Is a four door , V-8 powered car, built on a similar but stretched chassis a four door GT-R or is it a replacement for the Q45 ? Competitor to the $50k M45 ? They do already produce a M45x all wheel drive starting at around $52k.
initially rumored to get a slightly downtuned version of the GT-R's 476-horsepower twin-turbo V6, but one source close to Nissan says the company is now leaning towards a slightly tuned-up version of the 5.0-liter V8 that powers the Infiniti FX50. In that guise, the four-door GT-R should develop around 420 hp. The seven-speed automatic gearbox mated to the FX's V8 will almost certainly migrate together with the 5.0-liter engine.
The four-door GT-R is expected to weigh around 4,080 pounds and cost in the neighborhood of $100,000. It's slated for a late-2010 debut.
