Technical Specs and Features in the 2012 Corvette and Corvette Grand Sport

Everything you need to know about the 2012 Corvette & Grand Sport


The 2012 Corvettes are arriving in the showrooms now, and of course, you want to know what's new for '12. Here's a compilation of all the changes to help you with your shopping and wish list:

2012 Base Corvette and Grand Sport

The 2012 base model Corvette represents an evolutionary change from 2011, with just a few feature and option changes. Chevy sources tell us that there will be big news coming out this year, and that news will almost certainly be about the new C7 revision of the Corvette line.

430 Horsepower LS3 Engine

Both base Corvette and Grand Sport models will continue to be powered by the 6.2-liter 430-horsepower (321 kW) and 424 lb.-ft. of torque (575 Nm) LS3 V-8. An optional dual-mode exhaust system brings a power rating increase to 436 horses (325 kW) and 428 lb.-ft. (580 Nm). A standard six-speed manual transmission and an optional six-speed automatic paddle-shift automatic are offered. Launch control is standard on manual-transmission-equipped models. It optimizes performance for full-throttle starts on a track. In competitive mode, the system will hold a predetermined engine speed while the driver pushes the throttle to the floor. That allows the driver to quickly release the clutch and the system modulates engine torque 100 times per second to maximize the available traction.

Chassis and Suspension

Both the base Corvette and Grand Sport models have a hydroformed steel rail backbone structure. Additionally, Corvette design features cored composite floors, an enclosed center tunnel, rear-mounted transmission for balanced weight distribution, and a unique aluminum cockpit structure.

All Corvette models offer two suspension choices that allow drivers to choose the setup that best suits their driving style. The standard suspension is tuned for a balance of ride comfort and precise handling and comes standard on the base Corvette, while the base Corvette's optional Z16 Performance Package is standard on Grand Sport.

The Z16 package includes extra cooling, stiffer springs and stabilizer bars, specific shock absorbers, larger brakes with six-piston front and four-piston rear cross-drilled rotors, specific tires and Z16-specific six-speed manual when ordered with six-speed manual transmission, or a performance rear axle ratio when ordered with the six-speed paddle shift automatic.

The optional Magnetic Selective Ride Control suspension features magneto-rheological dampers able to detect road surfaces, and adjust the damping rates to those surfaces almost instantly for optimal ride control. It includes larger, cross-drilled brake rotors.

Corvette Grand Sport Features

Over the basic Corvette package, the Grand Sport combines the base Corvette's LS3-based powertrain with the wide-body styling, a wider track and a racing-bred suspension similar to the Z06 for a distinctive model that delivers greater handling performance with wider wheels and tires, revised shock valving, upgraded sway bar and spring specifications, and specific gearing.

Grand Sport models may also be ordered with an optional "Heritage" package that includes iconic Grand Sport front fender hash marks offered in four colors, and custom seat embroidery. You can also specify optional brake caliper colors in red, yellow, silver and gray.

2012 Chevy Centennial Edition Corvette

The 2012 Corvette lineup celebrates Chevrolet's performance heritage with the 2012 Chevrolet Centennial Edition Corvette, which features a sleek black color scheme, unique design elements and Corvette's unsurpassed sports car technology. The special package is inspired by Chevrolet's racing-bred foundation and is offered on all Corvette models for 2012.
