Nissan confirmed last month that they would be installing a software update for the gearbox in the GT-R that was designed to minimize stress levels placed on the dual-clutch unit. While the VDC is engaged, tests have shown that the car is pulling off 0-60mph times in less than 3.3 seconds unofficially. This shaves 0.2 seconds off the official 3.5 second time of the current car.
The RPM level has increased beyond the current 2,000rpm limit when the VDC traction control system is turned on, on the flip side of things it also decreases the maximum allowable rpm limit when the VDC is switched off from 4,500rpm to 3,000-3,500rpm. The news of the unofficial acceleration times comes from officals at the Nissan Tochigi Assembly plant, where engineers have been testing the new car.
Rumors are also circling that a GT-R owner with the software update has posted a quarter-mile time of 11.347 seconds at 120.85mph, with stock Dunlop tires. Amazing! Incidentally, this time is quicker than official times posted by many reviewers during the launch of the original car last year.
Nissan engineers are starting to think that by lowering the maximum RPM levels at launch, less wheel spin occurs and the car launches of the line both quicker and more smoothly. Now, things should be interesting when engineers test the new SpecV model.
