Nissan’s official motorsport partner Nismo has further developed the GT-R Nismo GT3 using data collected from teams running the current 2012 model, as well as its own dyno tests and customer feedback clinics.
Key areas where engineers were focused were engine performance and durability, aerodynamics, brake balance, and gear ratio and suspension improvements.
Power still comes from a twin-turbocharged 3.8-liter V-6, just like in the road-going GT-R, however, as part of the 2013 update, the engine has received new camshaft timing. Many of the engine’s moving components were also reinforced to improve durability. Peak output is rated at more than 543 horsepower and 469 pound-feet of torque.
Note, on this racing version of the GT-R, drive goes to the rear wheels only, and the six-speed dual-clutch transmission has been replaced by a six-speed sequential manual unit. Overall weight is just 2,866 pounds.
Outside the car, several modifications were made to enhance aerodynamics: canards were added to the front, and the front fender louvers were enlarged. The positioning of the rear wing was also optimized. These changes are said to have improved aerodynamic balance between the front and rear, while also increasing downforce.
Nismo has started taking orders for the new 2013 Nissan GT-R Nismo GT3 race car, which is priced from 35,000,000 yen (approximately $437,140). Nismo also plans to offer owners of the current 2012 model an upgrade package that will see their cars match the specification of the 2013 model.
