According to GTRBlog, the new Spec-V variant of the Nissan GT-R will not increase engine output, instead remaining at the 478 horsepower standard on the Series II GT-R. An Overboost button will replace the transmission mode selection button, indicating the Spec-V will be stuck in the "Race" setting. The base price of 15,750,000 yen (approx. $167,849) can be increased to 16,978,000 yen (approx. $180,705) with all options equipped.
According to the leaked specifications, Nissan has attempted to address the GT-R's biggest weakness with the Spec-V model: its weight. The rear seats in the Spec-V are replaced by a carbon fiber shelf, while the grille and rear wing are also replaced with carbon fiber alternatives.
20-inch forged aluminum wheels and an upgraded Bilstein Damptronic suspension package are standard, while Dunlop tires a no-cost option. Other options include a Thatcham alarm system and a Bose audio system upgrade. Ultimate Black Pearl paint is a new 577,500 yen ($6,148) option.
If these specifications are correct, Nissan has decided to forego power modifications altogether-a proposition which goes against other rumors we've heard about a Spec-V tuned to the sound of at least 520 horsepower. Given this list of specifications and pricing, we're not sure the Spec-V offers the same value as the base GT-R (read our review of the 2009 Nissan GT-R), which can be had for 7,770,000 yen (approx. $82,698). We'll have to wait until Nissan releases the official specifications for the 2010 Nissan GT-R Spec-V to find out for sure.
It is unknown whether the Spec-V will be made available stateside, but according to GTRBlog, the 2010 Nissan GT-R Spec-V will be available in Japan on January 8th, 2009.
