Nissan is adding some more updates to the 2014 GT-R supercar, which goes on sale early next year. The new updates are expected to increase the performance and improve the GT-R's ride and handling. Notable modifications include improved engine response in both the mid- and upper-rpm rev range, increased body rigidity, and specification changes to the shock absorbers, springs and front stabilizer. As a result, the vehicle's overall performance is dramatically increased, high-speed stability improved and ride quality is more refined.
The engine's performance has been improved thanks to the incorporation of high-output injectors that more precisely control fuel injection improve mid-range engine response and acceleration at higher rpms. A specially-developed orifice to the relief valve have been added to the turbocharger bypass, which will suppress the rapid decrease of the forced injection pressure, helping to sustain acceleration at high rpms. Nissan has also added a specially-designed baffle plate to the oil pan to better stabilize the oil pressure at high speeds.
To improve the GT-R's handling, Nissan engineers lowered the vehicle's center of gravity in accordance with the deflection of the suspension bushings and tires. The specifications of the shock absorbers and front stabilizer have also been modified. Reinforcements were also added at two locations in the dash panel bar and instrument panel member , resulting in improved suspension performance and increased body rigidity.
