Nissan 2020 Vision Gran Turismo concept

Nissan is the latest manufacturer to unveil a virtual concept car for Polyphony's Gran Turismo game, appropriately based on its GTR flagship.Designed by the team at Nissan Design Europe in London, the 2020 Vision Gran Turismo takes the broad themes of the GTR and transposes them into a far more extreme expression of its character. The vertical front and circular rear lamps are familiar, while the tapered DLO and bodyside graphic are also recognizable, but its proportions are new – wildly low and wide. Wilder still is its surfacing, with extreme offsets through its body section, layered aero elements and wheel arches that incorporate exhaust outlets behind the front wheels and a Gandini-like hexagonal rear graphic.The rear of the Visions Gran Turismo is dominated by the vast lower venturi to suck it to the (virtual) circuit and an equally dominant wing pressing it down, bracketed by the iconic four round lamps.
