Nissan Focuses on the Chassis Dynamics for the 2014 GT-R

Rather than just squeeze more power out of its superb 3.8-litre biturbo V6 in search of ever more impressive performance figures, Nissan has concentrated on improving the chassis dynamics of its GT-R supercar for the 2014 model year, which is actually much more difficult.

The numbers are unchanged: 397kW at 6400rpm and 628Nm from 3200 – 5800rpm, delivering a 0-100km/h sprint in just 2.9 seconds and a top speed of 315km/h, driving all four wheels through a six-speed dual-clutch transmission. Impressive enough.

But the GT-R’s suspension is now symmetrical to reduce load fluctuation between the four wheels for improved stability and more consistent grip, the electronically controlled damper valves have been revised to make better use of the suspension stroke for improved road-holding, and the front stabilizer spring rates re-calibrated for more consistent tire contact with the road, as well as better straight-line stability.

The GT-R now comes with Dunlop SP Sport Maxx GT 600 DSST CTT 255/40 ZRF20 front and 285/35 ZRF20 rear tires with stiffer sidewalls to reduce deformation and improve steering response under hard cornering.

Braking calibration has been returned for a firmer and more linear response at everyday speeds, allowing for smoother braking to be more intuitive, especially in the wet, while the steering has been tweaked to reduce the effort needed for in-town maneuvering without sacrificing high-speed stability and feedback.

Multi-LED adaptive headlights are now standard, which adjust the angle of the lighting beam according to speed. The four LED units have intensive LED high-beam and three different low-beam settings, including long distance and wide illumination; at higher speeds, actuators in the headlight cluster adjust the angle of the LED projectors to throw the light further, even the assembly process of the body-shell, built up from steel, carbon fiber and die-cast aluminium components, has been revised for increased rigidity.

New for 2014 is a carbon-fiber boot lid and rear wing, as an option to replace the standard boot lid, reducing weight, increasing rear down force and pushing the GT-R’s Cool Quotient from Left Field to Clean off the Wall.
