Corvette Convertible

Every Corvette provides peace of mind with OnStar(1) (standard for one year) with nine safety and security services. An OnStar Advisor is always ready to help in a variety of situations, whether you've locked your keys your car(2) or have a flat tire. And with Automatic Crash Response, built-in sensors can automatically alert an OnStar Advisor who is immediately connected in to your vehicle and can request emergency help be sent to your determined location.

The ZR1(1) is powered by a 6.2 Liter aluminum-block V8 boosted by an Eaton® TVS™ (Twin Vortices Series) supercharger for a total power output of 638 hp at 6500 rpm and 604 lb.-ft. of torque at 3800 rpm. It is the most powerful motor ever to occupy the engine bay of a General Motors production car.

The supercharger features four lobes instead of the usual three for higher power and efficiency. It also features an intercooler to cool down the airflow charge for more power. In addition, nozzles squirt cooling oil into the underside of each piston.

The engine also features a dual-pressure fuel injection system for peak performance during multiple operating conditions.

Like the LS7 engine in the Z06, the LS9 features titanium connecting rods and exhaust valves as well as a dry-sump oil system with a larger capacity reservoir - now 10.5 quarts. The LS9 is hand-assembled at the GM Performance Build Center in Wixom, MI.

ZR1(1) employs Brembo® brakes, which feature carbon ceramic matrix rotors for excellent heat dissipation. The advantages are superior friction and thermal properties. Unlike the carbon rotors on a race car, these rotors do not need to be hot in order to work effectively. The vented and cross drilled rotors measure 15.5 inches (394mm) in diameter in the front and 15 inches (380mm) in the rear - making them among the largest carbon ceramic rotors available on any production vehicle. While large in size, they are also low in mass, saving approximately 11 lbs. per rotor over comparable cast-iron units. Like the Z06, the ZR1 features six-piston front calipers and four-piston rear calipers. The front brakes utilize a single pad measuring 148 sq. cm. (22.9 sq. in.) in surface area - double the 70 sq. cm. (10.9 sq. in.) pad size of Z06.

Z06 and ZR1(1) achieve a power-to-weight ratio of 6.3 lbs. per hp for Z06 and 5.2 lbs. per hp for ZR1, in part because of their lightweight yet strong aluminum frames combined with their magnesium roof structure and engine cradle. The aluminum structure weighs only 278 pounds — that’s 136 pounds less than coupe. The structure includes full-length hydroformed aluminum rails to provide exceptional strength and dimensional accuracy.

The low beams are a xenon high intensity discharge projector lamp, coupled with tungsten-halogen high beams. At 900 lumens, the headlamps provide significant forward lighting power. The low beams also have a spread pattern that is wider than conventional headlamps.
