Car maker Infinti has announced that it is putting the FX "Sebastian Vettel version" concept car into production.
The 5.0-litre V8 was tuned to provide 420PS and given design and engineering tweaks and a high-downforce aerodynamics package in a collaboration between Infiniti and Red Bull Racing, giving it a top-line speed of 300km/h.
The company unveiled the concept car at Frankfurt billed as "the most focused and exclusive sports crossover ever built."
The concept car was sparked off by a conversation between Red Bull's world champion Sebastian Vettel and Infiniti Chief Creative Officer Shiro Nakamura at the 2011 Geneva Motor Show, and was the star of Infiniti's stand at the September's Frankfurt Motor Show.
"Doing the FX Sebastian Vettel version for Frankfurt was fun," said Infiniti Executive Vice President Andy Palmer. "But it's also a kind of pilot. It's about our equivalent of [Mercedes-Benz] AMG or [BMW] M Cars.
"We wanted to test the organisation and see if it could cope with this type of special version," Palmer continued. "Sebastian's FX demonstrates we are able to do low volume specials and the FX Sebastian Vettel version is one of the first that will go to market.”
Details of the production version - including availability, volumes and prices - are still to be announced.
Vettel is an Infiniti Global Brand Ambassador and already drove an Infiniti FX as his regular street car.
