2009 Nissan GT-R

We’re only a few days away from the official public unveiling of the 2009 Nissan GT-R, but a few motoring magazines have already had their go at Nissan’s at long last attempt at the successor to the venerable R34 Skyline GT-R.

Nissan aims the car at the likes of the the Porsche 911 Turbo - nearly every manufacturer of a new “supercar” seems to have the 911 Turbo as the holy grail of benchmarks, an example is the recent Audi R8. AutoWeek magazine has a test drive report online and even compares the new GT-R with a 911 Turbo in a mini shootout of sorts, as a 911 Turbo had been provided by Nissan on the track day.

According to AutoWeek, the new engine is called the VR38 and sits slightly behind the front axle, with two of its 6 cylinders before the front axle and the other four behind it. The VR38 engine sends power to a GR6 twin-clutch 6-speed gearbox at the rear transaxle through a carbon fiber propellor shaft. Another shaft runs from the gearbox at the transaxle to the front axle for the front wheels. We now officially have shift times for this gearbox - 200ms. In comparison, Volkswagen’s DSG does upshifts in 8ms but unanticipated shifts that have not been preselected by the DSG can take up to 400ms.

The car uses Nissan’s new PM platform, or Prime Midship platform, which uses a combination of polypropylene, carbon composite and the usual metals used in a car chassis for its construction.
