Infiniti 4-door GT-R renderings

Is not the first time you hear about this: Nissan is working on a four-door version of the 2009 GT-R. It will be sold under the Infiniti badge starting 2010.

A source told AutoExpress, "Launching new cars these days is all about recouping investment costs. Nissan chief Carlos Ghosn wouldn’t have approved the GT-R if its hi-tech chassis and transmission were not going to be used in some way in other models – including products from Infiniti and [sister firm] Renault. It’s the only way of making it pay. So building a performance Infi-niti saloon is perfect business sense."

The 4-doors GT-R is internally known as the R50. It will be powered by a choice of two powerplants. Most obvious is the GT-R’s 473bhp twin-turbo 3.8-litre V6 – although they may be forced to use the 5.0-litre V8 unit recently unveiled in Infiniti’s all-new FX50 SUV. That’s because Nissan produces the GT-R’s engine by hand – output is only 50 a day, which would be nowhere near enough to supply Infiniti, too.
