Nissan has taken the wraps off an updated version of its GT-R supercar, which is set to debut later this month at the 2011 Tokyo motor show.
The new car has only been revealed in its Japanese spec, but this is the model that will be sold elsewhere around the globe early next year as the 2013 Nissan GT-R.
First and foremost, the car is getting a power boost that sees output from its twin-turbocharged 3.8-liter engine rise to 542 horsepower at 6,400 rpm and 466 pound-feet of torque at 3,200 rpm. Best of all, that torque will plateau from 3,200 revs all the way up to 5,800.
At the same time, engine response and torque at mid- and low-speeds, and power at high revolutions, has been significantly improved, but Nissan also claims that the car has been made even more fuel efficient. Final EPA numbers aren’t expected until closer to the new GT-R’s local launch next year.
The improvements are mostly due thanks to improved intake efficiency. Air flow resistance, for example, has been reduced by adding an intake manifold fitted to the head of each unit and the use of special resin in the enlarged air intake duct for the intercooler.
Air flow resistance has also been reduced through a more compact underfloor catalyzer, which improves emissions efficiency and reduces weight. Finally, for improved exhaust valve cooling performance, a newly-designed metallic sodium-filled valve has been adopted. Valve control timing, the air mixture ratio and ignition timing have all been improved as well.
