Infiniti released further details and pictures of the FX Sebastian Vettel edition, the car they refer to as the ultimate FX.

This is the car designed and built in six months based on Vettel’s desired specs. So the main focus here was to make it faster and more racing driver like! Changes including increased power, lower weight, derestricted top speed, longer gearing, increased downforce and lowered and stiffer suspension

The FX gets an aerodynamic package that gives 30% improvement in the coefficient of lift (Cl) a 5 per cent lower coefficient of drag (Cd), and consists of splitter, sills, front grille, mirror covers and rear diffuser and wing, all made of carbon fiber for low weight and rigidity. The car also rides 20mm lower than standard FXs.

Then there is the 21-inch black multispoke alloys with silver rims, bespoke for this car, new LED lights at front and a bunch of Vettel logos and badges to make the car even more distinguishable.

Engine-wise, this car gets the 390 hp 5.0-litre V8, tuned up to 420 hp for Vettel, which enables it to go form 0 to 100 km.h in 5.6 seconds and achieve max speed of 300 km/h.

Other technical features Vettel waned on his car include dual-flow path (DFP) dampers with continuous damping control (CDC); the same wishbone front/multilink rear suspension, much of it constructed out of aluminium; opposed 4-piston (front), 2-piston (rear) calipers for the 355/350mm brake discs; and vehicle-speed variable rack and pinion steering.

The interior is modified too, with black carbon – real, not appliqué – on the doors and centre console. Highlights that would normally be silver chrome are treated to a special black chrome finish, while in true F1 style, Alcantara is used on the steering wheel and gearshift paddles. Special seats, with extra support, are covered in black quilted suede cloth finished with purple stitching and special “SV” logos. The material also features on the pillars, roof lining and sun visors.
