The fastest, most powerful production Chevrolet Corvette ever, the 2018 Corvette ZR1 has been unveiled. Slated to hit U.S showrooms as early as March 2018, the ZR1 will take its place atop the Corvette Z06 (and Z07 Performance Package model), borrowing know-how and technology from the company's C7.R racecar program.
The all-new ZR1 delivers the highest specific output of any Corvette, thanks to a supercharged (LT5) 6.2-litre V8 engine producing a whopping 755 hp (more than a Porsche GT2 RS) and 969 Nm of torque.
The power gains come courtesy of a new, intercooled supercharger system that offers 52 percent more displacement than the Corvette Z06’s (LT4) supercharger. The ZR1 also uses GM’s first dual-fuel-injection system, which employs a primary direct injection and supplemental port injection, to achieve its output.
The all-new ZR1 also produces 117 hp more than the sixth-generation ZR1, which delivered 638 hp from its supercharged 6.2-litre V8.
Both seven-speed manual and eight-speed paddle-shift automatic transmissions are available. This is the first time an automatic transmission will be offered in a ZR1. Top speed is claimed to be in excess of 330km/h.
Two wind tunnel-honed aerodynamics packages are offered - a standard rear ‘Low Wing’, which delivers the highest top speed and an optional two-way-adjustable ‘High Wing’ that offers up to 430 kg of downforce, suited for track use. A Chevrolet-first, downforce-enhancing front underwing is also fitted as standard.
Both of the ZR1’s wings are tied into the chassis, like the Corvette Racing C7.R racecar, for added strength.
The front fascia is designed to channel air for the engine and drivetrain cooling, concealing four new radiators - bringing the total number of heat-exchangers to 13.
The ZR1 wears Michelin Pilot Sport Cup 2 tyres, and is modulated by a specific tuning for the chassis and 'Magnetic Ride' active suspension to achieve greater traction.
The Corvette ZR1 also debuts the new Sebring Orange Design Package. Centered on its Sebring Orange Tintcoat exterior color, the package also includes orange brake calipers, orange rocker and splitter accent stripes, orange seat belts, orange interior stitching and unique, bronze aluminum interior trim.
On the inside – the driver-focused cockpit includes standard leather-trimmed seats, with suede-microfiber inserts. Optionally, customers can opt for competition sports seats, a 'Performance Data Recorder' and Bose premium audio system.
