Tony Chen is completely re-imagining the rally car with his Audi Rally King concept. Chen's concept looks to be a cross between an SUV and a sedan. Everything about it is futuristic, from its smooth and shiny body to unique wheels. The smooth and shiny body was undoubtedly designed to be as aerodynamic as possible. The wheels are another story entirely and look as if they can change according to what type of terrain is currently being traversed.
Chen hasn't said what size or type of engine he imagines powering his Audi Rally King. In this day and age it's likely to be a hybrid, especially if Chen envisions his concept competing in endurance events where fuel and time both come at a premium.
