The Bertone Mantide is a design study based on the Corvette ZR1 first unveiled in 2009 over a series of YouTube videos known simply as Project M.
The Mantide has better performance figures than the ZR1, due in part to its highly advanced aerodynamics and significant weight savings. The overall vehicle weight has been reduced with using carbon fibre for all body panels, interior trim, seats and even the wheels. The Mantide is 220 lb (100 kg) lighter than the ZR1.
The Mantide has a 638 bhp (476 kW; 647 PS) supercharged 6,162 cc (376.0 cu in) V8 engine that produces 604 lb·ft (819 N·m) of torque at 3800 rpm.
The aerodynamic results are excellent, with drag reduced by 25% (Cd 0.298) and a 30% improvement over the ZR1 in down force.
The performances are exciting 0-62 mph (0–100 km/h) in 3.2 seconds and a top speed of 351 km/h (218 mph). Bertone plans to produce 10 Mantides at $2 million each.
