The Nissan Nismo GT-R RC (Racing Competition), a production race car, will be showcased at the 2011 Tokyo Auto Salon. According to the company statement, the NISSAN NISMO GT-R RC is the latest addition to the RC (Racing Competition) line of high performance production model race cars that NISMO has developed and outfitted.
It is based on top performance NISSAN GT-R (R35) road car. Notably, the vehicle is built up from the pre-facelift version of the R35 GT-R. NISMO didn’t tweak the vehicle’s VR38DETT 3.8 liter twin-turbo V6, which means that it delivers more than 485 hp and 588 Nm of torque.
The vehicle doesn’t have the 530hp output that the refreshed version of the street-destined GT-R boasts but this racer features a lighter body, due to the use of carbon fiber for the bumper, hood, trunk lid and rear wing. It also has acrylic rear windows. As a result, the vehicle only weighs 1,520 kg.
Nismo fitted the car with a height adjustable racing suspension and a beefier braking system that uses 410 mm (front) and 380 mm (rear) rotors.
The vehicle sits on ADVAN 290/710 R20 slick tires, which are standard for all RC models. When it comes to safety features, the vehicle has an FIA standards-compliant weld-in roll cage, bucket seat & driver safety harness, fire extinguisher, ATL 120 liter safety fuel cell and air jacks.
GT-R RC can be used on production car series from anywhere around the world. It is priced at JPY 20,790,000 ($250,500).
The partition wall of the Nissan GT-R’s engine compartment makes use of a rigid and lightweight strut supporting bar made from carbon composite with an aluminum honeycomb. Engineers were also able to improve the body's responsiveness by connecting the right and left struts for quickly suspension input reception.
Nissan also installed an extra support member in the passenger's side dash panel, with the connection with engine compartment enhancing rigidity, and thereby improving chassis responsiveness.
The carmaker also modified the front suspension, the spring, shock absorber as well as stabilizer to improve the vertical load response of the tires. By increasing the front caster angle from 5 degrees 35 minutes to 6 degrees, engineers were also able to increase the car’s stability in a straight line as well as the tires’ road-holding ability while steering.
Meanwhile, Nissan lowered the roll center height to enhance the grip of the tires’ inside edge during turning maneuvers. The new Nissan GT-R also features a newly developed aluminum free-piston shock absorber that can generate more precise damping force, resulting to a load shift that rapidly responds to the driver's input as well as a stable road-holding capability. The new GT-R also delivers quality and seamless ride thanks to reduced shock absorber friction.
