Nissan’s rather unhinged SpecV GT-R will go on sale in Europe for more than double its sibling’s price early next year. How do they justify that? A very limited number of SpecVs will be sold in Europe for 2010, and at £124,900, compared to the stock GT-R’s £58,100, it’s awfully challenging to not dismiss SpecV as a hugely cynical marketing exercise. Ostensibly the 40 cars allocated for Europe are to celebrate the 40th anniversary of GT-R badged Nissan products in EU…Really expensive brakesSo what do you get for double the price of a stock GT-R? Distressingly, not much.Peak power remains at 357kW, yet Nissan claims engine performance improves courtesy of a high-gear boost device which spools up the twin-turbos to optimal operational speed in a shorter amount of time. The new titanium exhaust should shore up the car's acoustic signature too...SpecV’s suspension gains revised springs and new fixed-rate dampers at each wheel corner, whilst a set of carbon-ceramic brakes (specifically made by Brembo for the SpecV) tally nearly one-third of the price increase over a stock GT-R. Those rotors might look dirty, but the cost as much as a Porsche Cayman...Heroically pointless or just heinously overpriced?The SpecV adds carbon-fibre weaving to the aft spoiler, grille and brake ducts to melt down the car’s mass.Forged alloy wheels from NISMO round off the car’s styling signature (although the stock GT-R's Rays wheels are probably prettier) and trim a few grams from each wheel corner too. All things considered though, SpecV is only 60kg lighter than a GT-R, which is less than a passenger…Plainly impossible to justify, the SpecV will undoubtedly find 40 very willing (and disturbed) owners, who’ll happily pay double for a negligible increase in performance over the stock GT-R.Considering the GT-R's only real weakness is track-day abused brake fade, if you’re a keen weekend helmet-and-driving-gloves type, those £40 000 Brembo’s are a bargain as part of the SpecV deal.
