Nissan has revealed that it will once again upgrade the GT-R supercar. The changes announced so far concern the Japanese-market Nissan GT-R, which goes on sale there on November 19, although we believe the updates will be applied to the American-market car next year.
The Nissan GT-R has been tweaked nearly every year since it launched; for the 2013 model year, Nissan bumped power from 530 hp to 545 hp. Nissan says the latest round of changes was made in response to input from customers, many of whom frequently take the GT-R to track days and other high-performance driving events. For starters, the twin-turbo 3.8-liter V-6 engine receives new, higher-pressure fuel injectors designed to improve throttle response at high engine speeds; a baffled oil pan helps maintain oil pressure during aggressive cornering; a tweaked turbocharger bypass allows for more consistent performance at high engine speeds; and Nissan will now stock Motul Competition oil at the dealership to sate track-driving owners.
The Nissan GT-R also benefits from several chassis changes, including cam bolts that allow for easier alignment adjustment, redesigned front suspension components to help lower the car's center of gravity, and Nissan also tightened the connection between the driveshaft and hub bearings to make the drivetrain more durable. The car also has two additional braces behind the dashboard to reduce body flex.
Finally, Nissan made a few small tweaks to the car's interior. Base models receive a new stitching color with a thicker seam on the instrument panel and door trim, Black Edition cars get a red-and-black steering wheel and optional carbon-fiber Recaro bucket seats, and the GT-R Premium gains hand-stitched leather front seats and a new amber-and-black interior color choice.
A Nissan spokesman in the U.S. couldn't comment on which of the Japanese-market updates would be applied to the American GT-R. However, the company confirmed that the 2014 Nissan GT-R will roll out in Europe and North America from January 2013. Expect Nissan to reveal changes to the U.S.-market GT-R in the next few months.
