 Audi A8L, 2014

A superior design, hand-built quality, systematic lightweight construction and an abundance of high-end technologies. The A8 makes Audi among the innovation leaders in the worldwide luxury segment, the most demanding automobile category. One great strength of the big sedan is its low weight. The Audi A8 3.0 TFSI with the normal wheelbase has a curb weight of just 1,830 kilograms (4,034.46 lb) - best-in-class for models with all-wheel drive.

The key factor in its lightweight construction is the body, which except for the B-pillars is made entirely of aluminum. An Audi Space Frame (ASF) design, it tips the scales at just 231 kilograms (509.27 lb), roughly 40 percent less than a comparable steel construction. The ASF body also makes it possible to reduce weight in many other areas, from the brakes to the fuel tank.

Length (5.14 meters [16.86 ft]), wheelbase (2.99 meters [9.81 ft]), width (1.95 meters [6.40 ft]) and height (1.46 meters [4.79 ft]) remain unchanged, giving the Audi A8 the sportiest look in the segment. The A8 L gains an additional 13 centimeters (5.12 in) in both length and wheelbase. Equipped with a TDI engine, both body variants have a drag coefficient of just 0.26. This same figure with a TFSI engine is 0.27.

The A8 Audi paid great attention to the acoustics. Additional noise damping measures reduce the already low interior noise level even further. The trunk now has a maximum of 520 liters (18.36 cubic feet) and can be loaded substantially better thanks to the altered layout. The optional power trunk closing assist means that the entire car can be locked at the touch of a button.

Dynamic, yet harmoniously elegant - the big sedan's design has become even more expressive. The engine hood, the single-frame grille and the front bumper are even more sculptured and precise; the lower edge of the headlights is straight. In the German market, LED headlights are standard in all models with a V8 engine.

The Audi headlights with optional Matrix LED technology, which sets new benchmarks with respect to design and technology. With these headlights, the high-beam unit is made up of 25 individual segments. The small light-emitting diodes, which work in conjunction with lenses and reflectors connected in series, are activated and deactivated or dimmed individually according to the situation. This enables the system to react precisely to other cars, which it recognizes using a camera, and always illuminate the road brightly. Additional features of the new headlights are the intelligent cornering light, new-look daytime running lights and dynamic turn signals.

The LED lights at the rear of the new Audi A8 have also become flatter and are joined together by a continuous chrome strip. In all models except the S8, the redesigned bumper houses two rhomboid tailpipes. Chrome strips in the lower section of the body, fine inserts in the door handles and high-gloss black window frames round out the distinctive features. There is a choice of 12 exterior colors, including five new ones. Wheels are available in sizes up to 21 inches with 275/35-series tires.

The engines: more power with greater efficiency
Besides the S8, A8 L W12 quattro and A8 hybrid models, the new Audi A8 will be offered in the German market with two TFSI gasoline engines and two TDI units. A package of measures to reduce friction reduce fuel consumption by as much as ten percent, and most engines have also seen an increase in power. All engines already satisfy the requirements of the Euro 6 standard.

Under the hood of the A8 3.0 TFSI quattro is a V6 engine whose mechanical compressor can be deactivated. Power output is now 228 kW (310 hp), an increase of 15 kW (20 hp). The V6 accelerates the standard wheelbase version of the sedan from 0 to 100 km/h (62.14 mph) in 5.7 seconds. Top speed is electronically restricted to 250 km/h (155.34 mph). It consumes on average 7.8 liters per 100 kilometers (30.16 US mpg), corresponding to 183 grams CO2 per kilometer (294.51 g/mile).

The twin-turbo V8 in the A8 4.0 TFSI quattro now produces 320 kW (435 hp), 11 kW (15 hp) more than before. Key performance data: from 0 to 100 km/h (62.14 mph) in 4.5 seconds; average fuel consumption 9.1 liters per 100 kilometers (25.85 US mpg), corresponding to 213 grams CO2 per kilometer (342.79 g/mile). The Audi cylinder on demand (COD) system plays a major role in this efficiency by deactivating four of the eight cylinders under part load.

With average fuel consumption of 5.9 liters per 100 kilometers (39.87 US mpg), corresponding to 155 grams CO2 per kilometer (249.45 g/mile), the 3.0 TDI clean diesel set a new record in the all-wheel-drive luxury segment. The V6 diesel engine's output has been bumped up 6 kW (8 hp) to 190 kW (258 hp). It now accelerates the sedan from 0 to 100 km/h (62.14 mph) in 5.9 seconds.

The 4.2 TDI clean diesel tops the A8 lineup, delivering 850 Nm (626.93 lb-ft) to the crankshaft. Audi has boosted its output by a whopping 25 kW (34 hp) to 283 kW (385 hp). Equipped with the powerful V8 diesel, the A8 completes the standard sprint in 4.7 seconds, and average fuel consumption is 7.4 liters per 100 kilometers (31.79 US mpg), which corresponds to 194 grams CO2 per kilometer (312.21 g/mile).

Powertrain: tiptronic and quattro
All variants of the model series are equipped with a fast and smooth-shifting, eight-speed tiptronic. The transmission, which can be controlled electronically using an elegant selector lever as well as paddles on the steering wheel, works in conjunction with the quattro permanent all-wheel drive system. The latter is standard in the A8 series (except for the A8 hybrid). If desired, Audi will combine quattro all-wheel drive with the optional sport differential on the rear axle. The power can then be distributed between the rear wheels as needed for even more agile handling. The sport differential is standard in the S8 and the A8 4.2 TDI clean diesel quattro.

The Audi A8 owes its sporty character in large part to the sophisticated chassis. Axle load distribution is balanced, and all wheel control arms are aluminum. The Audi drive select system, which enables the driver to influence the function of various technical modules such as the steering and the accelerator characteristic, is standard. It also controls the adaptive air suspension with adaptive damping, which adjusts the body's ride height to the speed driven. Audi also offers the air suspension with a sporty setup upon request.

The power steering now uses an efficient electromechanical drive that reduces fuel consumption and also enables the use of numerous assistance systems. The optional dynamic steering varies its ratio with the car's speed. All brake discs are internally vented. Carbon fiber ceramic brake discs are available for V8 models, the S8 and the A8 L W12.

One new component of Audi's lightweight construction technology are the 9J x 20 aluminum-technology wheels. These are based on forged support wheels that are joined via a special process to a ten-spoke design element of high-strength polymer. This technology gives designers the freedom to use large-area, yet three-dimensional designs.

Elegant and airy: the interior
The interior of the Audi flagship enchants with its elegant, airy lines. The instrument panel is lean and low, and below the windshield is a long arc - the wrap-around. Space is generous in every seat. The broad range of options for the front seats includes ventilation and massage functions with five programs and intensities each.

Audi offers electrically adjustable, individual rear seats as an option for the A8 and the A8 L. The A8 L is also available with a continuous, leather-covered center console. Equipped with every available luxury feature, the relaxation seat with electrically adjustable footrest is the first-class solution here.

Among the numerous individual options available for the A8 family are four-zone deluxe automatic air conditioning, the panorama glass roof, convenience key with power door closing assist, privacy windows, a cooler, folding tables and an ionizer to improve air quality.

Audi quality knows no compromise. All of the materials in the new A8 have been carefully chosen and precisely worked. Lovingly executed details document the hand-built character, from the barely visible gaps in the two-piece inlays to the ambient lighting with its adjustable LED light to the seat covers in premium grades of leather. The best of these is the new Unicum leather in nutmeg brown, which is particularly natural-looking, soft and breathable.

 Audi A8, 2014

The superior design, hand-built quality, systematic lightweight construction and an abundance of high-end technologies: Audi presents the comprehensively updated A8, its successful flagship, at the 2013 IAA in Frankfurt am Main. The engine lineup has once again become more powerful and efficient; new assistance systems and the innovative Matrix LED headlights make driving more composed than ever.

Audi A3 Sport back S-Line, 2014

 

 

 Audi A3 Sport back S-Line, 2014

Sporty, versatile and functional - Audi presented the new A3 Sport back. The compact five-door model with the spacious luggage compartment is ground breakingly light thanks to ultra lightweight technology. The engines are powerful and highly efficient. The infotainment with the intuitive connect technology and the driver assistance systems available in the new Audi A3 Sport back set new standards in the premium compact segment. The overall design language concentrates on the essentials, with each individual design element making a confident aesthetic statement.

A lightweight car is a prerequisite for sportiness and efficiency. ultra lightweight technology from Audi reduces the weight of the new Audi A3 Sport back by as much as 90 kilograms (198.42 lb) compared with the previous version. Equipped with the 1.4 TFSI engine, the five-door model has a curb weight (without driver) of just 1,205 kilograms (2,656.57 lb). Hot-shaped steels are used in the occupant cell of the new A3 Sport back to reduce the weight. The complete occupant cell is 37 kilograms (81.57 lb) lighter overall than in the previous model. Significant weight reductions were also achieved in the interior and with the engines. Audi, worldwide pioneer in lightweight construction, has reversed the weight spiral and once again set a new record.

The body of the new Audi A3 Spor tback is long and lean. While the length (4,310 millimeters [14.14 ft]), width (1,780 millimeters [5.84 ft]) and height (1,425 millimeters [4.68 ft]) of the new model are only slightly greater than on the previous model, the wheelbase is now significantly longer at 2,636 millimeters (8.65 ft), an increase of 58 millimeters (2.28 in).

The front end is low; the roof arch spans a dome that extends beyond the subtle roof spoiler to the muscular tail end. The design with the three side windows is taut, with every detail precise and expressive. The large wheel wells underscore the sporty aspirations of the new Audi A3 Sport back.

The distinctive, Stone Gray single-frame grille with the angled upper corners is the distinguishing element at the front of the vehicle. Its horizontal slats and the Audi rings are highlighted three-dimensionally. The flat headlights are works of art and give the new Audi A3 Sport back a determined gaze. Full LED headlights will be offered at a later time.

The interior of the new A3 Sport back is elegant, airy and cleanly designed. It carries over the dynamics of the exterior. The instrument panel with its curving front is slim and low. Together with the center console oriented toward the driver, it appears to float slightly.

Large, round air nozzles in jet design, the elegant user interface panel for the climate control system and sculpturally styled trim set the tone - with their polish they bring the quality of the full-size class into the new Audi A3 Sport back. The seats and steering wheels are new developments, and the car's user controls are clear and intuitive - as they are in every Audi. The compact five-door model offers a generous luggage capacity of between 380 and 1,220 liters (13.42 and 43.08 cu ft).

Audi ultra lightweight technology
ultra lightweight construction has long been a main pillar of the brand. Audi recorded a pioneering achievement in the use of aluminum as a body material back in 1994: The first A8 had a full-aluminum body in ASF (Audi Space Frame) technology.

ultra lightweight technology reduces the weight of the new Audi A3 Sport back by as much as 90 kilograms (199.42 lb) compared with the previous version. Equipped with the 1.4 TFSI engine, the compact five-door model has a curb weight (without driver) of just 1,205 kilograms (2,656.57 lb). Audi, worldwide pioneer in lightweight construction, has reversed the weight spiral and once again set a new record.

ultra lightweight construction in the body
The broad-based expertise of the Audi body development engineers is by no means restricted to a certain material, but rather encompasses all relevant materials. The multimaterial construction of the new Audi A3 Sportback is entirely in keeping with the motto "The right material at the right place for optimal function."

High-end components of hot-shaped steel in the occupant cell form a strong, yet lightweight structure. Before deformation, they are heated in a continuous flow furnace to nearly 1,000 degrees Celsius and are then cooled to about 200 degrees in a water-cooled stamping press.

This extreme temperature jump creates an iron-carbon structure with extreme tensile strength. Hot shaped steels are able to perform with relatively thin walls, and this makes them lightweight.

Hot-shaped steels represent a roughly 25 percent share of body materials. They are used in the transition from the front of the vehicle to the occupant cell, in the A-pillars, roof arch, center tunnel, side sills and floor panels. What is known as a tailored rolled blank forms the transition from the floor to the rear body section - its eleven individual segments are rolled into five different thicknesses.

The B-pillars also consist of this high-end steel; their lower sections are more flexible than above, since the energy of a side-impact collision must be absorbed here. All together, the hot-shaped steels in the new Audi A3 Sport back reduce the weight of the vehicle by 37 kilograms (81.57 lb) compared with the previous model.

High-strength and ultra-high-strength steel grades are used in many other body areas such as in the side members and in the floor of the passenger cell. The engine hood, fenders, the subframe of the front axle and the sections mounted behind the front bumper as crash absorbers are made of aluminum. Together the aluminum components save around twelve kilograms (26.46 lb), thus improving axle load distribution.

Processing aluminum components in body construction and joining these components with steel components are challenging tasks. The same is true of welding hot-shaped components, which are coated with a corrosion-inhibiting aluminum-silicon alloy. Audi benefits here from its extensive know-how in ultra lightweight construction - the joining technologies have been practice-proven for years now in models such as the TT. A number of very different joining technologies are used to assemble the new A3 Sportback, including bonding, clinching and punch riveting.

Between the side wall and the roof, which are both made of steel, a Plasmatron brazed seam produces the joint, where the allowable tolerance is just a few tenths of a millimeter. The finished seam is smoothed with brushes - the practically invisible zero-joint that is produced is an expression of the stringent precision thinking at Audi.

Unlike the previous model, the doors and window frames are stamped in one piece, and this also saves weight. The door hinges integrate a convenient new type of clamping mechanism.

Safety and aerodynamics
The new Audi A3 Sportback is tops when it comes to passive safety. In a frontal collision, the front cross-member distributes the forces to the two side members, which undergo defined deformation to dissipate these forces. The structural members for the engine and front suspension, as well as the sections in the upper area of the fenders, act as additional load paths. If necessary, the pedals are decoupled from the firewall; the steering column absorbs energy and is not displaced into the occupant cell.

In a side impact, the occupant cell offers excellent protection with its hot-shaped steel components such as the sills and B-pillars. In a rear-end collision, the bumper's cross members redirect loads to the large side members made of high-strength steel.

ultra lightweight construction in the interior
The Audi ultra lightweight principle is not limited to the body or to specific subassemblies and parts - developers always consider the vehicle as a whole, and in their work every gram counts. This is the only way the car's curb weight could be reduced by up to 90 kg (198.42 lb) compared with the previous model.

The engineers have internalized the Audi ultra lightweight principle, and in the interior of the new Audi A3 Sportback they also succeeded in eliminating every superfluous gram. The redesigned seats contribute a one kilogram (2.20 lb) weight savings; lightweight plastic inserts replace the steel wire used previously in the frame of the rear bench seat.

A new control unit arrangement requires fewer wires, thus reducing the weight by 1.5 kilograms (3.31 lb). The blower motor requires fewer coils, and the air conditioning system shed four kilograms (8.82 lb) of weight. The housing of the passenger airbag is made of polymer; the mounting for the MMI monitor is made of magnesium. Together these two solutions save 640 grams (1.41 lb). In the previous model, many linings in the interior were fastened with steel screws. In the new Audi A3 Sportback, polymer expanding rivets were used here for a weight savings of four grams (0.01 lb) per fastening point. When it comes to the Audi ultra lightweight construction principle, every gram counts.

ultra lightweight construction in engines and chassis
The engines of the new Audi A3 Sportback have shed a significant amount of weight as well. The engines of the new A3 have shed a lot of weight as well. The 1.8 TFSI, for example, weighs just a little over 130 kilograms (286.60 lb), while the 1.4 TFSI weighs in at just 107 kilograms (235.89 lb) - 21 kilograms (46.30 lb) less than the previous engine. With a weight difference of 15 kilograms (33.07 lb), the aluminum crankcase accounts for the largest share of reductions, but progress has also been made in many small engine details - e.g. in the new aluminum pistons and the hollow-bored connecting rod pins.

Environmental footprint
In developing the new A3, Audi conducted an environmental assessment of two of the engine versions. The 1.4 TFSI and the 2.0 TDI - both with a manual transmission - were subjected to a detailed analysis. Both versions offer clear benefits compared with their respective previous models. Greenhouse gas emissions, for example, are reduced by roughly two metric tons per model. This corresponds to roughly seven to nine percent of the greenhouse gas emissions over the entire life cycle. This is due in large part to the substantially lower fuel consumption and low weight of the new models. At the end of its life, about 95 percent of the new Audi A3 Sportback can be recycled.

Exterior design
The new Audi A3 Sportback is long and lean. While the length (4,310 millimeters [14.14 ft]), width (1,780 millimeters [5.84 ft]) and height (1,425 millimeters [4.68 ft]) are only slightly greater than on the previous model, the wheelbase is now significantly longer at 2,636 millimeters (8.65 ft), an increase of 58 millimeters (2.28 in). The overall design language of the new Audi A3 Sportback concentrates on the essentials, with each individual design element making a clear and confident aesthetic statement. The front end is low; the roof arch spans a dome that extends beyond the subtle roof spoiler to the muscular tail end. The ratio of metal surface area to windows is two-thirds to one-third - a typical proportion for Audi.

The design with the three side windows is taut, with every detail precise and expressive. The tautly curved surfaces, the sharp shoulder of the body and the relatively narrow, sharply inclined C-pillar give the new Audi A3 Sportback its typical character. The sharply defined tornado line articulates the flank below the windows and evokes a powerful shoulder. The dynamic line above the side sills runs upward toward the rear. The large, precisely defined wheel wells and the subtle roof spoiler underscore the sporty aspirations of the new Audi A3 Sportback. The same applies to the exterior mirrors with integrated LED turn signals, which like with a sports car are mounted on the doors.

The distinguishing element of the front end is the distinctive, Stone Gray single-frame grille with the angled upper corners. Its horizontal slats and the Audi rings are highlighted three-dimensionally. A slender, chrome-plated frame surrounds the grille. Large air intakes up front hint at the supreme power of the engines.

The flat headlights are works of art of the highest technical precision and give the new Audi A3 Sportback a determined gaze. They are styled in a wedge shape, and their lower edges are contoured in a slight wave. In the optional xenon plus modules, the LED daytime running lights form clear, visually uniform contours of lights at the upper and lower edges, which suggest the shape of an eyebrow. The turn signal lights are at the pointed corner of the headlight behind the "wing" - a narrow, chrome-plated fin that is a typical Audi feature.

As an option, Audi can supply the new A3 Sportback with the high-beam assistant, and - in conjunction with xenon plus headlights - with adaptive light. It integrates a special curve, cornering and intersection light function and can be supplemented by variable headlight range control. It works together with the front-facing camera to adjust the light-dark boundary of the headlights automatically in response to approaching vehicles or the vehicles ahead. Full LED headlights will be offered somewhat later.

The rear is sculptured, and the split rear lights underscore its width. Audi offers LED rear lights in combination with the xenon plus headlights; LED light conductors appear to form a continuous arch. The adaptive brake light, which pulses at high frequency during hard braking, is standard. A sharp crease sets off the diffuser. Depending on the engine, the exhaust system terminates in one or two tailpipes on the left side of the car. On the Ambition and Ambiente they are chrome-plated.

The S line exterior package further sharpens the look of the premium compact car. The single-frame grille is painted in a high-gloss black, honeycomb-look screens with fog lights fill the large air inlets, which are bordered by powerful edges. Suggested air inlets that extend towards the wheels create distinctive visual accents. The sills have distinctive add-on strips. The roof spoiler has been lengthened, the bumper has an additional edge, the platinum gray diffuser includes a honeycomb-pattern insert, and the tailpipes of the exhaust system are chrome-plated.

There are twelve paint colors from which to choose. The solid finishes are called Amalfi White, Brilliant Red and Brilliant Black. The metallic finishes are Beluga Brown, Dakota Gray, Ice Silver, Glacier White, Monsoon Gray, Scuba Blue and Shiraz Red. The pearl-effect finishes Phantom Black and Misano Red round out the selection. The optional high-gloss package offers small highlights in the area of the side windows (standard with the Ambiente line).

Interior
The interior of the new Audi A3 Sportback is marked by an elegant, clean and light design. The dynamics of the exterior are also fully carried over here; the lines and surfaces are dynamic and taut. In the style of the larger Audi model series, a long arch called the wrap-around runs below the windshield. The instrument panel with its curving front is slim and low. Together with the center console oriented slightly toward the driver, it appears to float slightly.

The clean ergonomics are a classic Audi strength. The MMI operating system with the power-retractable monitor is available with the MMI radio and above. The center tunnel console, framed on both sides by knee pads in the style of the TT sports car, presents a clean, well-organized look. Thanks to the new electromechanical parking brake, there is no longer any brake lever; this has created space for the terminal of the optional MMI user interface. The armrest is adjustable in length and height.

The driver seats at an elegant steering wheel. Depending on the version, it has three or four spokes, a flat-bottomed rim, multifunction buttons and shift paddles. The large dial instruments can be easily read at a glance. The driver information system, which is available with an optional color monitor, displays useful data on a 3.5-inch display. These include such things as the current radio station or song title, speed, outside temperature and the time, as well as information from the navigation and driver assistance systems if present. The on-board computer provides information on fuel consumption, average speed and the time and distance driven. Furthermore, the integrated efficiency program supports an economical driving style.

Audi A3 Sedan, 2014

 

 

 Audi A3 Sedan, 2014

With the launch of the A3 Sedan in spring 2013, Audi is entering the world's largest market segment, the class of compact sedans. The dynamic four-door car offers all of the strengths of the A3 model series - with low weight thanks to lightweight design, powerful and highly efficient engines and numerous high-end solutions for infotainment as well as driver assistance systems. The top model of the series is the S3 Sedan with 221 kW (300 hp).

The Exterior Design
The Audi A3 Sedan has a sporty stance on the road, and it is precise and highly expressive in every detail. Its design is a cross between the classic three-box concept and the coupé philosophy. The "tornado line" design element forms a distinct light-refracting edge that runs over the entire side. The overhangs are short. The four-door car has a 2.64 meter (8.66 ft) long wheelbase and an overall length of 4.46 meters (14.63 ft).

Above the side sills, the dynamic line rises more sharply than on the other two A3 models. The side surfaces are more intensively curved, and the wheel arches are slightly more flared. With a width of 1.80 meters (5.91 ft), the A3 Sedan is eleven mm (0.43 in) wider than the A3 Sportback; its height (1.42 meters [4.66 ft]) is still nine mm (0.35 in) lower than that of the Sportback.

The four-door car also expresses independent lines in the contour of its hood, in the bumpers, air intakes and its implementation of the singleframe grille. At the rear, the spoiler is integrated in the trunk lid, and the lights emphasize the car's horizontal lines with their broad and low cuts. LED technology is available as an option. Audi will also be offering full-LED headlights right at market launch - their innovative technology and distinctive appearance underscore the exceptional positioning of the Audi A3 Sedan.

The Body
With a 1.4 TFSI engine, the sedan has a curb weight of just 1,250 kg (2,755.78 lb). Audi uses many hot-shaped steel parts in the passenger compartment for low weight and maximum strength, while the engine hood is made of aluminum. The body is very rigid, crash-safe and quiet.

The strict dictate of lightweight design carries over into the interior and the engines as well. The four-cylinder engine weighs just over 100 kg (220.46 lb).

The Powertrain
When the Audi A3 Sedan launches in Germany and Europe, the engine line-up will consist of three four-cylinder engines. Completely redesigned, the engines bring together efficiency technologies from Audi - direct fuel injection, turbocharging, innovative thermal management and the start-stop-system. The line-up of engines and transmissions will grow further, and will include two new basic engines.

The 2.0 TDI produces 110 kW (150 hp) and develops 320 Nm (236.02 lb-ft) of torque. It accelerates the Audi A3 Sedan from 0 to 100 km/h (62.14 mph) in 8.7 seconds and takes it to a top speed of 220 km/h (136.70 mph). Its combined fuel consumption is 4.1 liters per 100 km (57.37 US mpg) - for a CO2 equivalent of 108 grams per km (172.20 g/mile).

Key performance parameters of the 1.4 TFSI are 103 kW (140 hp) and 250 Nm (184.39 lb-ft). At low engine load, the COD (cylinder on demand) system deactivates two cylinders. The 1.4-liter engine gives the car a combined fuel consumption of just 4.7 liters fuel per 100 km (50.05 US mpg); its CO2 emissions are 109 grams per km (175.42 g/mile). It takes just 8.4 seconds to accelerate from 0 to 100 km/h (62.14 mph), and the car's top speed with this engine is 213 km/h (132.35 mph).

The 1.8 TFSI produces 132 kW (180 hp) and 250 Nm (184.39 lb-ft) of torque. It utilizes an extensive package of high-end technologies, including dual injection into the combustion chambers and the induction manifold. It enables sporty performance, taking 7.3 seconds for the standard sprint to 100 km/h (62.14 mph) and reaching a top speed of 235 km/h (146.02 mph). Its combined fuel consumption is 5.6 liters per 100 km (42.00 US mpg), equivalent to 129 grams CO2 per km (207.61 g/mile).

Depending on the engine, either a manual six-speed transmission or the S tronic is used. The dual-clutch transmission shifts the gears without any noticeable break in propulsive power. It is controlled by either the selector lever or paddles on the steering wheel.

The D shifting map is laid out for maximum fuel efficiency, while the rev levels are somewhat higher in the sporty S mode. In cooperation with the Audi drive select vehicle dynamics system, the S tronic offers a free-wheeling function in its efficiency mode which further reduces fuel consumption.

Chassis
The pole position that the Audi A3 Sedan has enjoyed in its segment is largely due to its chassis engineering. Providing the foundation here is a finely balanced axle load distribution (60 percent front and 40 percent rear, varies somewhat for different engines). All engines are tilted twelve degrees towards the rear, while the front wheel suspensions are placed far forward.

The front suspension is a MacPherson design with A-arms and aluminum pivot bearings. It is joined to an aluminum subframe. The electromechanically assisted steering system operates sensitively and efficiently together with various assistance systems. In the four-link rear suspension, which utilizes a steel crossmember, the springs and shock absorbers are mounted separately. The sport suspensions for the Ambition line and S line lower the body by up to 25 mm (0.98 in).

The Audi A3 Sedan has 16- to 18-inch-wheels; quattro GmbH can also deliver wheels up to 19 inches in diameter. The front brake discs are internally ventilated.

Electronic stabilization control or ESC also includes an electronic differential lock. In fast driving through curves, it brakes the inside front wheel very slightly to minimize understeering and improve traction.

The Interior
The interior of the Audi A3 Sedan is characterized by impressive attention to detail. The lines and surfaces are cleanly designed, and a long arc spans the width of the windshield. The instrument panel with its curved front is slender, and the center console is slightly turned towards the driver. The optional color display of the driver information system (DIS) shows images in highly detailed 3D graphics.

Starting with the MMI Radio system, the MMI operating system has an electrically extending screen. Its terminal is housed in the console of the center tunnel. The electromechanical parking brake is activated by a pushbutton. The steering wheel has either three or four spokes, depending on the version. The customer can also order the steering wheel with a flat bottom, multifunction keys and shift paddles. Audi can also install sport seats in the front as an option. They are standard in the Ambition line, where S sport seats with integrated head restraints are available as an option.

The interior colors - black, titan gray, pashmina beige and chestnut brown - are based on the specific equipment line. The two-tone Audi design selection lasso brown creates an exclusive color world. The S line sport package, which can be ordered for the A3 Sedan Ambition, immerses the interior space entirely in black. Available upholstery materials include fabric covers, a mix of fabric and artificial leather, Milano leather and a combination of Pearl nappa leather and Alcantara.

Audi A3 Sportback g-tron, 2014

 

 

 Audi A3 Sportback g-tron, 2014

The Audi is taking a large step towards sustainable future mobility with the A3 Sportback g-tron. The five-door premium compact model, which will appear on the market at the end of the year, runs on both the fossil fuel natural gas and on climate-friendly Audi e-gas, which Audi itself produces at a recently completed power-to-gas plant. It innovatively combines ecological balance, economy and high-tech solutions.

The Audi A3 Sportback g-tron, the brand's first natural gas car to go into production, reveals the sheer depth of the technological expertise of Audi - from ultra lightweight technology through the highly advanced infotainment to the driver assistance systems. It showcases state-of-the-art CNG technology (CNG = compressed natural gas), complete with the fuel storage technology. Its two pressurized tanks beneath the trunk floor each hold around seven kilograms (15.43 lb) of gas; they essentially use the recess for the spare wheel, thus impinging only minimally on the load capacity.

These tanks, which store the gas at a pressure of 200 bar, use the ultra lightweight construction principle of Audi: They weigh 70 percent less than conventional steel bottles, each of them weighing 27 kilograms (59.52 lb) less than an equivalent steel version. Their composition reveals an innovative layout: The inner layer consists of a gas-impermeable polyamide matrix, while a second layer of carbon fiber reinforced polymer (CFRP) gives the tank its extremely high strength; a third layer of glass fiber reinforced polymer (GFRP) provides protection against damage from the outside. Epoxy resin is used to bind the fiber reinforced materials.

A second highlight of the Audi A3 Sportback g-tron is its electronic gas pressure regulator. This compact and lightweight component reduces the high pressure of the gas flowing from the cylinders down to around five to nine bar in two stages. It ensures that the right pressure is always present in the gas rail and at the injector valves - low pressure for efficient driving in the lower speed range, and higher when the driver wants more power and torque.

When the pressure in the tank falls below 10 bar when there remains about 0.6 kilogram (1.32 lb) of gas, the engine management automatically switches to gasoline operation. The Audi A3 Sportback g-tron is designed as a bi-fuel concept. In the NEDC cycle it drives over 400 kilometers (248.55 miles) on gas and a further 900 kilometers (559.23 miles) on gasoline, so its overall range is comparable to a TDI. The driver information system always shows current consumption; two displays in the instrument cluster indicate the tanks' fuel level. The filler pipes for both are located behind the same flap.

After refueling, and whenever it is very cold, the Audi A3 Sportback g-tron is started with gasoline initially, then it is switched over to natural gas as quickly as possible. Its engine is a modified 1.4 TFSI; the cylinder head, turbocharger, injection system and catalytic converter are specifically designed to run on gas. With an output of 81 kW (110 hp) and 200 Nm (147.51 lb-ft) of torque, the compact five-door model accelerates from 0 to 100 km/h (62.14 mph) in less than 11 seconds; it achieves a top speed of more than 190 km/h (118.06 mph).

The Audi A3 Sportback g-tron is the benchmark in its segment for efficiency and economy. Its CO2 emissions in the exhaust gas remain below 95 grams per km (152.89 g/mile) in the NEDC cycle, and the fuel costs for the customer are around four euros per 100 km (62.14 miles). Over 100 km (62.14 miles), the compact car uses on average less than 3.5 kilograms (7.72 lb) of natural gas or Audi e-gas - the fuel that is produced in the Audi e-gas project from CO2 and water using renewable power. This fuel is a major step into the future of mobility for the brand with the four rings - Audi is the first carmaker to be establishing production facilities for a whole chain of sustainable energy sources.

The e-gas plant that Audi has set up in Werlte (Emsland) involes two major process stages - electrolysis and methanation. In the first step, the plant uses renewable power to break water down into oxygen and hydrogen in three electrolyzers. The hydrogen obtained from this process can be stored separately if required, for powering future fuel-cell vehicles.

Audi A3 e-tron Concept, 2013

 

 Audi A3 e-tron Concept, 2013

The Audi A3 Sportback e-tron from Audi is a latest-generation plug-in-hybrid car. The premium compact vehicle will go on sale from 2014 and is a genuine Audi. It combines sporty power with impressive efficiency and abundant driving enjoyment with unrestricted everyday utility. The A3 Sportback e-tron offers 150 kW (204 hp) of system power and achieves average consumption of only 1.5 liters per 100 km (156.81 US mpg) of gasoline. In the electric mode its operating range is up to 50 kilometers (31.07 miles), with the TFSI engine adding a further 890 km (553.02 miles).

From 0 to 100 km/h (62.14 mph) in 7.6 seconds and a top speed of 222 km/h (137.94 mph) - the Audi A3 Sportback e-tron adds an extra highlight to the sporty character of the compact premium car line. In accordance with the ECE standard for plug-in hybrid vehicles, its average CO2 emissions are a mere 35 grams per km (56.33 g/mile) - equivalent to consumption of 1.5 liters of fuel per 100 km (156.81 US mpg).

Thanks to the ultra lightweight construction philosophy of Audi, the unladen five-door model complete with all electrical components weighs less than 1,580 kilo-grams (3,483.30 lb), with space for five occupants and plenty of cargo. It comes complete with all the brand's strengths - elegant design, sporty chassis, top-notch ergonomics, excellent build quality and an extensive choice of high-end assistance and infotainment systems.

The 1.4 TFSI combustion engine is one of the most modern power units of Audi. Inside the engine compartment, looking in the direction of travel, it is positioned a few centimeters further to the right than usual, to create space for the high-voltage components. Its crankcase is made from diecast aluminum, weighing little more than 100 kg (220.46 lb).

The four-cylinder engine is state of the art in every respect - its low frictional losses, its turbocharger, its intercooler and its thermal management. One special feature is the way the exhaust manifold is integrated into the cylinder head. After a cold start, it brings the coolant swiftly up to operating temperature. At high loads the water jacket lowers the temperature of the exhaust gas.

Developing 110 kW (150 hp) and 250 Nm (184.39 lb-ft), the 1.4 TFSI is a powerful unit. It supplies peak torque across the entire speed range from 1,750 through 4,000 rpm, thus harmonizing excellently with the electric motor. The maximum of 330 Nm (243.40 lb-ft) is available virtually from the off, and is maintained constantly across a broad speed range up to about 2,200 rpm. Its maximum output is 75 kW. The system output of the A3 Sportback e-tron is 150 kW (204 hp), and system torque is 350 Nm (258.15 lb-ft). With the combination of electric motor and combustion engine, an overall operating range of up to 940 kilometers (584.09 miles) is possible. And its road performance is unwaveringly sporty: It takes a mere 4.9 seconds to sprint from 0 to 60 km/h (37.28 mph).

The electric motor is a permanently excited synchronous machine. It weighs 34 kilograms (74.96 lb) and is liquid-cooled via a cooling jacket in the stator. The electric motor is located between the engine's dual-mass flywheel and the newly developed separating clutch, the K0 clutch. When the TFSI starts, it is tow-started by the electric motor via the clutch. As soon as the former has achieved the same speed as the electric motor, the clutch is opened. This smooth, highly precise process takes place within half a second.

 Audi A3 Cabriolet, 2014

Sporty, elegant and multi-faceted - Audi presents the new A3 Cabriolet. The compact four-seater impresses at first glance with its flowing lines and soft top. It is also at the top of its class technically - with systematic lightweight design, new engines, multi-faceted networking and high-performance assistance systems.

The Exterior design
The new Audi A3 Cabriolet has grown compared to the previous model: its length increased from 4.24 to 4.42 meters (13.91 to 14.50 ft), its wheelbase from 2.58 to 2.60 meters (8.46 to 8.53 ft) and its width from 1.77 to 1.79 meters (5.81 to 5.87 ft). Only its height (1.41 meters [4.63 ft]) was reduced by 15 millimeters (0.59 in). This gives the four-seat convertible a more elegant and sporty look on the road. Luggage capacity grew by 60 liters (2.12 cubic ft), and it is easier to load. The wheel housings can handle wheels up to 19 inches in size.

The front of the Audi A3 Cabriolet is characterized by the Singleframe radiator grille. The flat headlights give it a resolute look; they emphasize the horizontal styling and the air intakes in the bumper. Audi offers headlights with LED technology as an option; they are the only LED headlights in the compact segment to offer variable headlight leveling control.

The rear overhang plays a key role in the harmonious proportions of the two-door car. The windshield frame is made of aluminum - and an aluminum-look trim strip runs around the entire car. On the flanks, the design features a taut tornado line and contoured sheet metal surfaces that create a fascinating interplay of light and shadow.

The soft top
The new A3 Cabriolet has a soft cloth top that is stretched over a lightweight kinematic mechanism made of magnesium-steel, and it complements the car's design perfectly. At the press of a button, the top opens or closes electro-hydraulically in less than 18 seconds, even while driving up to 50 km/h (31.07 mph). In the opened state, the top - folded into three layers - rests in a tray that barely affects luggage capacity, which is 287 liters (10.14 cubic ft).

The fully automatic soft top has a glass rear window and is offered in Black as standard. A fully automatic acoustic top is available as an alternative; it has a thicker inner foam layer which reduces the already low interior noise level of the Audi A3 Cabriolet even more. The acoustic top is available in the three exterior colors of Black, Gray and Brown, and its roofliner is available in black and lunar silver. A wind deflector is standard for the Ambiente trim line, and head-level heating is an option for the front seats. An active rollover protection system protects the occupants in case of a rollover accident. It consists of two spring-loaded plates that are recessed into the body.

Body
In the base version, the car's curb weight is just 1,365 kilograms (3009.31 lb) - the new Audi A3 Cabriolet is around 50 kilograms (110.23 lb) lighter than the previous model despite its larger size and better comfort. Including its special reinforcements, which deliver high torsional stiffness, the body-in-white weighs 30 kilograms (66.14 lb) less than previously; the engine hood is made of aluminum. Weight was also significantly reduced in the interior and in the engines. This let Audi - a pioneer in this technical field - set an impressive best value in the compact class. Customers can choose from 16 different exterior paints for the body.

Interior
Elegantly drawn lines and clean surfaces also typify the interior design of the new Audi A3 Cabriolet. The instrument panel is lean and low, its front is slightly curved, and the center console is angled slightly towards the driver. The large, round air vents in jet design, the control panel for the air conditioner and the three-dimensional trim strips bring premium class elegance into the interior. The optional lighting package includes a touch-sensitive switch for the reading lights - a feature being offered for the first time.
