Some concepts are production ready. Others, like the Renault Trezor Concept, are not. Unapologetically impractical, this low-slung GT has a single-piece clamshell roof that opens upwards to provide access to the interior. Speaking of which, it has a red wood dashboard, lounge-like seats, three screens, and a Formula 1-inspired rectangular steering wheel that puts you in control of the 350 hp electric motor, capable of moving the car from 0-62 mph in under four seconds. Outside, there's red glazing, C-shaped lights, carbon bodywork with contrasting finishes, and red fiber optic lighting in the rear.
