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.
