Chevrolet Corvette C7 Stingray, 2014
The Chevrolet is redefining modern performance with the debut of the all-new Chevrolet Corvette C7 Stingray. And only a Corvette with the perfect balance of technology, design and performance can wear the iconic Stingray designation.
The 2014 Corvette Stingray is the most powerful standard model ever, with an estimated 450 horsepower (335 kW) and 450 lb.-ft. of torque (610 Nm). It is also the most capable standard model ever, able to accelerate from 0-60 in less than four seconds and achieve more than 1g in cornering grip. It is expected to be the most fuel-efficient Chevrolet Corvette, exceeding the EPA-estimated 26 mpg of the previous model.
The all-new Chevrolet Corvette C7 Stingray shares only two parts with the previous generation Corvette. It incorporates an all-new frame structure and chassis, a new powertrain and supporting technologies, as well as completely new exterior and interior designs. Highlights:
- An interior that includes real carbon fiber, aluminum and hand-wrapped leather materials, two new seat choices - each featuring a lightweight magnesium frame for exceptional support - and dual eight-inch configurable driver/infotainment screens
- Advanced driver technologies, including a five-position Drive Mode Selector that tailors 12 vehicle attributes to the fit the driver's environment and a new seven-speed manual transmission with Active Rev Matching that anticipates gear selections and matches engine speed for perfect shifts every time
- An all-new 6.2L LT1 V-8 engine combines advanced technologies, including direct injection, Active Fuel Management, continuously variable valve timing and an advanced combustion system that delivers more power while using less fuel
- Lightweight materials, including a carbon fiber hood and removable roof panel; composite fenders, doors and rear quarter panels; carbon-nano composite underbody panels and a new aluminum frame help shift weight rearward for an optimal 50/50 weight balance that supports a world-class power-to-weight ratio
- A sculptured exterior features advanced high-intensity discharge and light-emitting diode lighting and racing-proven aerodynamics that balance low drag for efficiency and performance elements for improved stability and track capability
- Track-capable Z51 Performance Package including: an electronic limited-slip differential, dry-sump oiling system, integral brake, differential and transmission cooling, as well as a unique aero package that further improves high-speed stability.
The new Corvette Stingray will be built at GM's Bowling Green, Ky., assembly plant, which underwent a $131-million upgrade, including approximately $52 million for a new body shop to manufacture the aluminum frame in-house for the first time.
The 2014 Corvette C7 Stingray coupe goes on sale in the third quarter of 2013.
Handcrafted, high-tech interior
The new Chevrolet Corvette Stingray interior blends fine materials and craftsmanship with advanced technologies that contribute to a more connected and more engaging driving experience, said Helen Emsley, interior design director.
The smaller, 14.1-inch-diameter (360 mm) steering wheel fosters a more direct, immediate feel to directional inputs. The attention to the driver extends to the smallest details, including the flat, precise stitching on the steering wheel designed to provide a smooth, consistent feel.
Precise and elegant stitching also is seen in the available Napa leather trim of the all-new seats.
Two seating choices will be offered: a GT seat for all-around comfort and a Competition Sport seat with more aggressive side bolstering which provides greater support on the track.
The frame structure for both seats is made of magnesium for greater strength and less weight than comparable steel frames. They're also more rigid, contributing to the enhanced feeling of support during performance driving.
Additional performance-enhancing details of the interior resulted from designers' "field trips" to GM's Proving Ground in Milford, Mich., where high-performance driving experiences spurred the design and implementation of several features, including a steel-reinforced grab bar on the center console for the passenger and soft-touch materials on the edge of the console, where the driver naturally braces during high-load cornering.
High-performance driving also influenced elements of the configurable display screens and available head-up display, which vary depending on the driving mode, including the Track display inspired by the C6.R.
The performance-supporting elements inside the new Corvette C7 Stingray are complemented by unprecedented attention to detail and build quality, including the sweeping arch motif over the driver cockpit trim and the seamless transition of the line from the instrument panel to the door.
All models feature a fully-wrapped interior, where every surface is covered with premium, soft-touch materials. Available materials, depending on the trim level, include Napa leather, aluminum, carbon fiber and micro-suede.
A blend of hand craftsmanship and machined precision is intended to ensure the fit, finish and ambience of the cabin is first-rate. The leather-wrapped instrument panel, for example, features hand-selected and hand-stretched materials for better grain matching with stitching performed by robots that deliver perfect seams.
There's even a micro-LED screen for the passenger's climate control placed below the vent on the on the dash away from the performance features on the instrument panel.
Driver-oriented technologies
At the core of the Chevrolet Corvette Stingray's driver-focused technologies is the cockpit-mounted Driver Mode Selector, which allows drivers to optimize the car for their driving preference and road conditions via five settings: Weather, Eco, Tour, Sport and Track.
The Driver Mode Selector is easy to use via a rotary knob near the shifter. The Tour mode is the default setting for everyday driving; Weather mode is designed primarily for added confidence while driving in rain and snow; Eco mode is for achieving optimal fuel economy; Sport mode is for spirited road driving and Track mode is for track use.
Twelve performance parameters are adjusted with the selection of each mode:
- Gauge cluster configuration: The Tour, Eco and Weather modes feature displays for trip data, audio and navigation; Sport mode shows classic, easy-to-read sports car gauges; and Track mode's configuration shows a gauge design based on the Corvette Racing C6.R race car display with lap timer
- ETC (Electronic Throttle Control): Adjusts the throttle input curve for the selected mode for improved responsiveness
- Paddle-shift automatic transmission: Adjusts shift comfort and shift points
- Active Fuel Management: in normal mode, the LT1 engine uses V-8 power during acceleration and V-4 power when coasting; in Eco mode the engine remains in V-4 mode to improve fuel economy until aggressive acceleration is needed
- Exhaust (active exhaust system): The system adjusts the timing of the electronically controlled exhaust valves to enhance audible feedback from the V-8 depending on the drive mode
- Electronic limited-slip differential (Z51): Adjusts the rate at which the limited slip engages, to balance between steering response and stability in different driving conditions; more aggressive performance in Sport and Track modes
- Steering: Assist effort is adjusted in the modes to provide the driver with the correct steering feel for the driving condition
- Magnetic Ride Control: Adjusts shock damping based on road conditions, from optimized comfort to performance driving
- Launch control: Available in Sport and Track modes for manual and automatic transmissions, providing maximum off-the-line acceleration
- Active handling (Stabili Trak stability control): A "competitive" setting is available in Sport and Track modes and is more suited for on-track conditions. It can also be disabled, giving the driver complete control
- Traction control: Weather mode tailors traction control and engine torque for driving in inclement conditions
- Performance Traction Management: Available in the Sport and Track modes and offers five settings of torque reduction and brake intervention for track driving.
