The crossover SUV that the Formula 1 world champion built, more or less, the Infiniti FX Sebastian Vettel Version is a 200-unit limited edition based on Infiniti’s FX50S Premium. If you don’t know Sebastian Vettel, he is, at 24, the youngest ever superstar of Grand Prix F1 racing, having won the championship for the last two years. Already an FX50 driver, used to pushing it on no-speed-limit German highways, he was approached by Infiniti as part of their partnership with his team sponsor, Red Bull, to up the ante. The Vettel Version is way more than a cosmetic makeover and branding (the car does have an upgraded interior and Vettel’s personal logo on it). Starting with the original 390 hp 5.0 liter V-8 engine, power has been increased to 420 hp, weight reduced, speed upped from 155 mph to a substantial 185 mph (a key Vettel spec), the suspension lowered and stiffened, and aerodynamics adjusted to increase downforce. Vettel is said to have worked closely with Infiniti on the project, and the Infiniti engineers in turn studied Vettel’s F1 car, borrowing ideas for the FX. The whole process took an intense six months, and the concept prototype has become a production reality for early 2013. The videos below include a bit eye and ear candy, and a cool mini-documentary covering the design process, with lots of Vettel face time. Top tier all the way.
