While Chevy's new 2016 extended-range electric Volt vehicle and the new Bolt EV concept car grabbed most of the attention during media day one (Jan. 12, 2015) at the North American International Auto Show in Detroit, the Corvette exhibit remained one of the most popular of the Chevrolet displays.
Two years after the introduction of the C7 Stingray, journalists from around the world still huddled around a 2015 Stingray and new Z06, opening the doors, sitting inside and taking photos of the cars from every angle. "Getting my picture in one of these beauties was tops on my list of things to do at the Detroit show," said one European journalist.
The Corvette Racing portion of the display featured one of the team's yellow racecars and an interesting trophy case full of drivers' helmets and awards the team has won.
Rounding out the display were Corvette engines that auto show visitors can touch and photograph up close. Another journalist from Asia said he "was amazed the Corvette can get so much power from an engine this size."
These photos provide a peak preview of the Corvette display. Enjoy the show!
To keep our readers updated on what's new with the 2015 Corvette, the following information was prepared by Chevrolet for distribution during the two days of media previews at the Detroit Auto Show, which opens to the public on Saturday, Jan. 17.

Corvette Stingray Design
Corvette Stingray’s provocative exterior styling is as functional as it is elegant. It makes a bold design statement that embraces the advanced technology of the car, while enhancing its overall performance in everything from the wind tunnel to the track.
Lighting is a signature element of the Corvette Stingray’s design and reinforces its high-tech aesthetic. At the front, indirect white LED lamps form a distinctive daytime styling cue. They are set in black-chrome lamp housings with standard HID projector headlamps. The turn signals feature edge-lit amber LED lighting.
The dual-element taillamps feature three-dimensional, sculpted lenses housing innovative indirect LED lighting. The state-of-the-art lighting uses hidden LED lamps that cast their light up from the bottom of the housing into a reverse reflector, creating an even glow. LED lamps are also used for the white backup lamps. The taillamps integrate functional aircraft-style air outlets for the available differential and transmission coolers.
The Corvette Stingray convertible features a fully electronic top that can be lowered remotely using the key fob. The top can also be opened or closed on the go, at speeds of up to 30 mph (50 km/h). Its folding mechanism is all-new and enables the top to be lowered in 21 seconds.
With the top up, the convertible is designed for a refined driving experience. A thick fabric top, along with sound-absorbing padding and a glass rear window, contributes to a quiet cabin and premium appearance.
With the top down, the Corvette Stingray’s signature profile is further accentuated. Behind the seat backs, dual black trim panels enhance the character lines of the tonneau cover. Corvette Stingray’s signature “waterfall” design originates in the valley between the seats, bringing the exterior color into the interior.
All Corvette Stingray models with the Z51 Performance Package feature integral coolers for the rear differential and transmission (the transmission cooler is also included with the optional automatic transmission). For coupe models, the air intakes are integrated on the rear quarter panels; and on convertible models, the air intakes are integrated into the underbody.
Airflow through the differential and transmission heat exchangers exits through the aircraft-inspired taillamp vents and lower-rear fascia air outlets. The Z51 Performance Package also includes brake-cooling ducts, a unique rear spoiler and additional air deflectors for enhanced track capability.

At the core of the 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 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.
Up to 12 performance parameters are adjusted with the selection of each mode, including:
- 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; in Eco mode the engine can operate in V-4 mode to improve fuel economy until aggressive acceleration is called for
- 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 Track mode for manual and automatic transmissions, providing maximum off-the-line acceleration
- Active handling (StabiliTrak stability control): A “competitive” setting is available in Track mode 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 Track mode and offers five settings of torque reduction and brake intervention for track driving.
Three configurable displays, including a pair of eight-inch screens and color head-up display, deliver personalized information and convey the different performance parameters of each drive mode.
The two eight-inch screens offer excellent visibility in direct sunlight, with 650 cd/m2 of brightness for the one integrated into the instrument cluster and 1,000 cd/m2 of brightness for the one in the center stack, making them among the brightest screens in the industry. The screen in the center stack also features touch-screen control with gesture recognition and can be lowered to reveal a hidden storage compartment that includes a USB input for device charging or uploads.
Performance Data Recorder
The award-winning, industry-first Performance Data Recorder – or PDR – enables users to record high-definition video, with telemetry overlays, of their driving experiences on and off the track. It was developed with Cosworth, the motorsports-engineering company that supplies the Corvette Racing team’s data acquisition and telemetry electronics system.
The PDR system includes three major components, all seamlessly integrated into the Corvette Stingray’s interior. First is a high-definition camera, mounted within the windshield header trim, which records the driver’s point-of-view through the windshield. Audio is recorded via a dedicated microphone in the cabin.
Second is a self-contained telemetry recorder, which uses a dedicated GPS receiver that operates at 5 hertz, or cycles per second – five times faster than the in-dash navigation system, which allows more precise positioning and corner traces. Finally, the system features a dedicated SD-card slot in the glove box for recording and transferring video and vehicle data. Recording time depends on the capacity of the memory card, but an 8-gigabyte card can record approximately 200 minutes, while a 32-GB card stores up to about 800 minutes – more than 13 hours of driving time.
The PDR system can record video with three data overlay options, each rendered in real time:
- Track Mode – shows the maximum level of data on the screen, including speed, rpm, g-force, a location-based map, lap time and more
- Sport Mode – shows fewer details on the overlay but includes key data including speed and g-force
- Touring Mode – simply records and displays video and audio of the drive with no data overlay
- Performance Mode – records performance metrics, such as 0 to 60 mph acceleration, 1/4-mile speed and elapsed time, and 0-100-0 mph runs.
The video can be viewed on the Corvette Stingray’s eight-inch color touchscreen when the car is parked, or downloaded to a computer for further editing, and for sharing video via social media sites. For users who want a more in-depth understanding of their performance, the PDR vehicle data can be opened in the included “Cosworth Toolbox” software, which combines Cosworth’s professional-level motorsport data analysis with an easy-to-use graphic interface.
Chevrolet MyLink and OnStar with 4G LTE
Chevrolet MyLink gives customers the best of both worlds when it comes to infotainment. It provides easy, intuitive operation of basic functions, yet it is also highly customizable and capable of linking up to 10 devices such as smartphones, SD cards and MP3 players, giving users more ways of staying connected. It is standard on all trim levels.
Enhanced connectivity and convenience includes a Text Message Alerts feature for smartphone users with Bluetooth profile (M.A.P.), which reads incoming texts through the vehicle’s speakers, and Siri Eyes Free for iPhone iOS 6 and iOS 7 users to enhance connectivity and convenience. Each enables voice-controlled connectivity, to help keep phones in pockets and hands on the wheel.
New OnStar with 4G LTE and built-in Wi-Fi hotspot provides a mobile hub for drivers and passengers, providing easier access to apps and services that require a high-speed data connection. 4G LTE is the most current and fastest mobile data network – 10 times faster than 3G. And with OnStar, it also offers stronger, broader coverage than smartphones on the same network and it’s easy to use: If the vehicle is on, the connection is on.
Corvette Stingray coupe and convertible take advantage of lightweight materials, advanced manufacturing techniques and technology transfer from the Corvette Racing program to produce an ideal 50/50 weight balance and to deliver world-class power-to-weight ratios.
The technologically advanced foundation is an aluminum frame structure so strong, no structural reinforcements are needed for the convertible model. The only changes are limited to accommodations for the folding top and repositioned safety belt mounts.
The frame features main rails composed of five customized aluminum segments, including aluminum extrusions at each end, a center main rail section and hollow-cast nodes at the suspension interface points. Each segment’s gauge varies in thickness from 2mm to 11mm, tailored – along with the shape – to optimize the strength requirements for each frame section with minimal weight.
The aluminum frame is manufactured using innovative manufacturing processes at GM’s Bowling Green, Ky., assembly plant. The state-of-the-art facility employs several advanced joining technologies to ensure dimensional accuracy within 0.75 mm. Each frame features:
- 439 spot-welds using a GM-patented process that uses a unique electrode designed specifically for aluminum
- 188 Flowdrill-machined fasteners, which are installed by a high-speed drill that extrudes the frame material to create a strong, integral collar that is tapped for bolt-on fasteners
- 113 feet of structural adhesives, used in conjunction with welding and fasteners to increase overall frame stiffness
- 37 feet of laser welds, which join frame sections via a precise beam of high energy that minimizes heat beyond the weld area for improved structural accuracy.
The frame’s greater strength and low weight are complemented by chassis elements also designed for low-mass strength, including hollow-cast aluminum front and rear cradles. Innovative use of materials also includes a standard carbon fiber hood on all Corvette Stingray models, and a carbon fiber roof panel on all coupes. In addition, underbody panels are created with carbon-nano composite technology, an advanced blend of traditional composite material and carbon fiber for reduced weight and improved strength. Fenders, doors, rear quarter panels and the rear hatch panel are made with light-density Sheet Molded Compound.
Performance and Efficiency
The Corvette Stingray’s 455 horses are generated by the LT1 6.2L Small Block V-8 engine, which also produces 460 lb-ft of torque (624 Nm). Its performance comes from combining advanced technologies such as direct injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing with an advanced combustion system. Z51-equipped models include a dry-sump oiling system.
The LT1 is backed by a choice of active, 2.75-inch-diameter exhaust systems. The standard system features a pair of butterfly valves that contribute to greater refinement at cruising speeds when the engine is operating in fuel-saving V-4 mode. The available performance variable-mode active exhaust system has two additional valves that open to a lower-restriction path through the mufflers. When open, these valves increase engine performance and produce a more powerful exhaust note – while also raising the engine’s output to 460 horsepower (343 kW) and 465 lb-ft of torque (630 Nm).
The LT1 is offered with an all-new seven-speed manual transmission with Active Rev Matching. It incorporates rev-matching technology for upshifts and downshifts. This driver-selectable feature can be easily engaged or disengaged via paddles on the steering wheel. The seven-speed is used with a new dual-mass flywheel and dual-disc clutch, which deliver greater shift quality and feel through lower inertia. The transmission with the Z51 Performance Package includes specific close-ratio gearing for more aggressive driving.
New for 2015 is an available eight-speed paddle-shift automatic transmission. Designed and built by GM, the new 8L90 transmission delivers world-class shift times that rival the best dual-clutch designs. It is also expected to contribute up to 5-percent greater efficiency, when compared to the previous six-speed automatic. EPA fuel economy test results are pending and will be announced later.
The new eight-speed makes the Corvette Stingray one of the few sports cars to offer a conventional manual transmission and an eight-speed automatic.
The Corvette Stingray’s chassis and suspension are designed to take advantage of the lighter, stiffer structure. Its rigidity allowed engineers to more precisely tune the suspension and steering for a more nimble and responsive driving experience. The components and their calibrations – from the brake size and damper rates to the steering system – are identical between coupes and convertible.
A racing-proven short/long-arm suspension design is used front and rear, with lightweight complementing components that include hollow lower control arms and aluminum rear toe links.
The Corvette Stingray rides on 18 x 8.5-inch front and 19 x 10-inch rear wheels, while models with the Z51 Performance Package roll on 19 x 8.5-inch front and 20 x 10-inch rear forged aluminum wheels – all shod with Michelin Pilot Super Sport run-flat tires developed specifically for the seventh-generation Corvette. As a result, the Corvette Stingray with the Z51 Performance Package is capable of 1.03g in cornering acceleration.
Additional suspension features:
Dampers – includes standard 35mm-piston Bilstein monotube shocks that connect to dual-path aluminum shock mounts that separate the shock rod and shock body load paths. The Z51 Performance Package comes with 45mm-piston Bilstein dampers for more aggressive body control and track capability. Z51 is available with the third-generation Magnetic Ride Control, which features a twin-wire/dual-coil damper system that reacts 40 percent faster than previous generations, enabling improved ride comfort and body control.
Steering – Electric power steering offers variable ratios and variable effort to tailor responsiveness and feel for each driving situation. It also delivers precise control and feedback to the driver, along with great variability of effort for high-performance driving, as well as excellent on-center sensitivity and linearity.
Axle – A smart electronic limited-slip differential (eLSD) is included in the Z51 Performance Package and continuously makes the most of the torque split between the rear wheels. The system features a hydraulically actuated clutch that can infinitely vary clutch engagement and can respond from open to full engagement in tenths of a second. It shifts torque based on a unique algorithm that factors in vehicle speed, steering input and throttle position to improve steering feel, handling balance and traction.
The eLSD is fully integrated with Electronic Stability Control and Performance Traction Management systems. Its calibrations vary among three modes, based on the Drive Mode Selector setting:
- Mode 1 is the default setting for normal driving and emphasizes vehicle stability
- Mode 2 is engaged when electronic stability control is turned off in the Sport or Track modes. This calibration enables more nimble turn-in and traction while accelerating out of a corner
- Mode 3 is automatically selected when Performance Traction Management is engaged. This calibration has the same function as Mode 2, but is fine-tuned to work with Performance Traction Management.
Brakes – Standard Brembo brakes, with four-piston fixed calipers derived from racing, deliver exceptional stopping power on the street or track. System highlights include:
- 12.6-inch (320 mm) front rotors and 13.3-inch (338 mm) rear rotors are standard and have 35-percent more swept area than previous-generation brakes. Consequently, stopping distance is improved 9 percent
- Dual-cast, slotted 13.6-inch (345 mm) front rotors and 13.3-inch (338 mm) slotted rear rotors are included with Z51 Performance Package. They have 6-percent more swept area than the previous-generation Grand Sport and are cooled front and rear for improved track capability. Consequently, stopping distance is improved 5 percent
- All brake packages have fixed four-piston front and rear calipers that are stiffer for more even pad wear, reduced drag and improved modulation.
