General Motors has finally revealed the all-new Chevrolet Corvette Grand Sport powered by its next-generation V8 engine that produces more torque than any other naturally aspirated V8 before it.
GM has also introduced the new Grand Sport X, which comes with an all-wheel drive system, featuring a front-axle electric motor.
The LS6 6.7-liter naturally aspirated V8 delivers 535 hp and 520 lb-ft of torque. It uses a 95 mm throttle body, a tunnel ram intake with high-velocity ports, a new lubrication system, forged pistons and rods, and revised exhaust manifolds.
In the Grand Sport, power is transmitted to the rear axle via an 8-speed dual-clutch automatic transmission. It also gets a quad center exhaust – a first for a pushrod V8.
While Magnetic Ride Control is standard, the Z52 Sport Performance Package adds a stiffer setup, Michelin Pilot Sport 4S tires, and J560 brakes from the Corvette Z06.
The Z53 Track Performance Package comes with carbon ceramic brakes, Michelin Pilot Sport Cup 2R tires, a track-focused chassis and an aero package which includes a carbon fibre splitter, dive planes, rockers, underbody strakes and a wing.
The Grand Sport X packs 721 hp and comes equipped with carbon ceramic brakes, Magnetic Ride Control and Michelin tyres. Like the ZR1X, this version of the ‘Vette has ‘Endurance’ and ‘Qualifying’ modes as well as a ‘Push-to-Pass’ button that unleashes the full potential of the powertrain. In the electric-only Stealth mode, the Grand Sport X is restricted to 50 mph.
