The Sebastian Vettel Infiniti FX50 Concept is an SUV. It was based on the FX Limited Edition of 2010 and has a different grille, a different carbon fiber spoiler (supposedly based on the F1 car), a rear wing instead of roof rails and other carbon fiber bits here and there. Chances are that this concept car will be produced as a marketing tool for Infiniti and to some extent Red Bull/Vettel.
Of course Sebastian Vettel is actually Infiniti's global ambassador and drives a normal FX50 on the road because of this. But an SUV as a first car? Can't he get the Infiniti luxury coupe instead as the first car with his name on it? The SUV compared to his Formula 1 car is as different as night and day or heaven and hell. It may look aggressive, but the bottomline is that the SUV is tall and huge. He should get a coupe instead.
Remember Michael Schumacher? When he was with Ferrari his name was plastered on small, nippy Fiats that could actually handle and drive well – like the Fiat Seicento Schumacher or the Stilo Schumacher. Even Fernando Alonso gets to promote the Maserati Gran Turismo. I suppose you can't choose too much from the hand that pays you.
