Nissan has unveiled the changes to its GT-R supercar, which will debut at the Tokyo Motor Show later this month.
Nissan has unveiled the Japanese-spec GT-R, which will be labeled as a 2012 model in Japan, but when it reaches the U.S. it will be the 2013 Nissan GT-R.
The 2013 Nissan GT-R is getting a boost under the hood. It’s twin-turbocharged 3.8L engine now packs 545 horsepower and 463 lb-ft. of torque. Nissan claims that the engine response and torque are mid and low engine speeds has now been improved thanks to improvements to air intake and exhaust efficiency; better air flow resistance, which has been reduced by the addition of an intake manifold fitted to the head of each unit; and reduced air flow resistance thanks to a more compact under floor catalyzer which improves emissions efficiency and reduces weight.
The transmission also gets upgrades thanks to a strengthened design of the shift fork arm and a firmer fixing bearing for the flywheel housing. A special differential oil R35 Competition Type 2189E (75W140), which was developed for competition is now used in every version of GT-R.
Ceramic brakes are now available as a factory-installed option and right-hand-drive versions of the GT-R now get an asymmetrical suspension setup that compensates for the driver and propeller shaft for the front wheels being located on the right side of the vehicle.
Overall the upgrades help the GT-R shave off about 8 to 10 seconds of its Nürburgring lap time. Nissan also claims that the 0-60 time will be about 2.7 seconds.
