The impressive-looking rendering of this vehicle may carry GT3 updates, but it remains road-legal, even if most will have a hard time trying to figure it out on which car it was based on.

The GT3 conversion adds a brand new body by Casborn Styling Studio, made using Carbon Ceramic Composites, a race and aerospace tested material, and its highlights are the pointed shark nose front, narrowed large air intakes, active front diffuser, side design rockers, rear wing and widened fenders. Images of the interior haven’t been released at this point, but its makers mention the custom HUD in a "jet fighter style", sport seats, steering wheel, gear shifter and headliner wrapped in Alcantara, a unique surround sound system, Bluetooth and Wi-Fi connectivity.

As a result, the car needs less than 3.1 seconds to reach 60mph (96km/h), compared to the stock version's 4.1sec with the manual and 3.9sec with the dual-clutch gearbox. Top speed is 210 mph (338 km/h), up from the electronically limited 155mph (250km/h).
