By besting their currently advertised 3.5-second run, Nissan firmly plants the car deeper into supercar territory at what is still a value price (relatively speaking). The new launch feature is primarily a software change in the transmission control unit, which decreases the max PRM at launch with Vehicle Dynamic Control (VDC) off from 4500 RPM to between 3000 and 3500 RPM.
But there's a twist: this new time was achieved while VDC was still on.
It seems the other change to VDC, which enabled a higher RPM at launch with the system on, provides enough juice to get it to there faster. We'll be curious to see what happens when they do a run with VDC off. In the meantime, the numbers aren't official yet but it was a Nissan test driver at the Nissan Tochigi test track so Nissan Japan should be announcing it any day now.
