New Corvette Revives Stingray Name

The seventh-generation Corvette unveiled on Sunday in Detroit promises 450 hp, 450 lb-ft of torque, a zero-to-60 mph time of less than four seconds and the ability to achieve more than 1G cornering grip.

The so-called C7, which goes on sale in the third quarter, resurrects the Stingray name last used in 1982. Entirely redesigned, the new vehicle's wheelbase is about one inch longer and an inch wider than the current model. General Motors Co. says only two parts carried over from the current model.

The Stingray's all-new 6.2-liter, direct-injection V-8 engine the standard 'Vette's most powerful ever is equipped with cylinder deactivation that operates as a V-4 during coasting or in moderate driving in Eco mode.

The engine delivers power to the rear wheels through one of two available transmissions. A seven-speed Tremec manual is equipped with an electronic system that automatically matches engine speed to the next selected gear. A six-speed Hydra-Matic automatic features paddle shifters and electronically adjustable shift points.

Four-pot Brembo brakes with fixed calipers are standard. GM says stopping distance has been shortened 9%, in part because the standard rotors have 35% more swept area than the previous model. Optional performance brakes have 6% more swept area and deliver 5% shorter braking distance than the current performance brake system.

The new car is shod with Michelin Pilot Super Sport run-flat tires developed specifically for the C7. GM says the tires deliver the same grip as wider tires used on previous models but are quieter, more nimble, deliver quicker steering response and are more fuel efficient. The standard Stingray has 18-inch wheels in front and 19-inchers in back. The Z51 performance package bumps up both diameters by one inch.

The C7's aluminum frame is 57% stiffer and 99 lbs lighter than the steel frame used in the C6 'Vette. The redesigned steering system is five times stiffer than the old configuration. A carbon fiber hood and roof panel are standard. Hollow-cast aluminum front and rear cradles are about 25% lighter and 20% stiffer than the solid units used in the C6 car. GM says the new chassis, coupled with the use of lighter materials, results in an ideal 50:50 weight distribution.

Drivers can tailor the behavior of the C7 with a programmable five-position selector that allows adjustment of 12 vehicle attributes, including exhaust system sound. Selecting Sport or Track modes activates a launch control system. Switching modes also changes the main instrument panel display.

GM says the Stingray's exterior borrows several aerodynamic tricks from the Corvette racing program to enhance high-speed stability. Air flowing through the grille and radiator exits through a hood vent that improves aerodynamics and reduces front-end lift.

Indirect LED lamps are used fore (daytime running lights) and aft (brake and backup lights). The tail lamps include integrated air outlets for the optional differential and transmission coolers.

Inside, the new 'Vette features significantly upgraded trim with two configurable eight-inch displays, one of which has a touch screen with gesture recognition. A color head-up display is optional. The steering wheel is only 14.1 inches in diameter.

Two seating choices the standard GT and more heavily bolstered Competition Sport are available. Both use magnesium frames that are stronger, lighter and more rigid than the previous design. The interior surfaces of all models are covered with premium soft-touch materials that, depending on trim package, include aluminum, carbon fiber, micro-suede and Napa leather.
