The big news is that the twin-turbo, 3.8-liter V-6 engine now produces 545 hp and 463 lb-ft of torque, up from 530 hp and 448 lb-ft for 2012. The power gain is courtesy of a more efficient intake and exhaust, and a larger intake duct for the intercooler. In addition, a revised shift fork and, firmer flywheel bearings, and motorsports-specification differential oil help make the dual-clutch transmission smoother and quieter.
The 2013 GT-R also is marginally more aerodynamic than the 2012 model, thanks to a new front fascia that cuts the coefficient of drag from 0.27 to 0.26. Black Edition models wear a new handmade carbon-fiber rear spoiler. Inside, the tachometer receives new blue accent lighting. Nissan says that the car’s suspension has been mildly retuned.
In addition, navigation, a backup camera, and Bluetooth connectivity become standard for the new model year. There is one small disappointment: Japanese-spec Nissan GT-Rs can be specified with a new “Track Pack”, which deletes the rear seat and includes two lightweight bucket seats, stiffer suspension, and lighter wheels. That option package won’t be coming to the American market.
The 2013 Nissan GT-R reaches showrooms in January 2012. Expect pricing figures to be announced closer to the launch date.
