Infiniti is go!

Nissan's upmarket brand, Infiniti, will launch in the UK in spring 2009 - and its four-strong model line-up is now out in the open for everyone to see.

The FX37 revealed in Paris is powered by Nissan's 316bhp 3.7-litre V6 petrol engine. It has a top speed of 145mph and goes from 0-62mph in 6.8 seconds.

FX37 GT models will come with 20-inch alloy wheels, a seven-speed automatic gearbox, leather upholstery, heated front seats, cornering-beam headlights and parking cameras and sensors.

The FX37 S will get 21-inch wheels, sports seats and continuous damping control.

It will be joined in Infiniti's UK showrooms by the EX37 4x4, and the G37 coupe and saloon models.
