Ever since the all-wheel-drive was introduced on the R32 GT-R, the Nissan sports coupe has always been lauded as a triumph of technology over Newtonian physics. It's rapier-sharp handling owed much of its success to the ATTESA-ETS all-wheel-drive system which channeled torque to the front wheels when the rear tyres lost grip. With the new R35 GT-R, Nissan has kept their performance flagship packed full of high-tech kit and to show it they've released a bunch of images to illustrate just what lies beneath Godzilla's skin.
One of the main differences between the R35 and the R32-R34 GT-R's is in the drivetrain layout. On the older cars, the layout was quite traditional. The front-mounted engine was bolted to a five or six-speed gearbox that had a transfer case mounted to the end, which then sent torque to conventional limited-slip differentials at both axles. On the R35 (click the picture above), the gearbox is now an automated-manual transaxle that resides inside the rear suspension subframe, leaving the engine all alone up front with only the front diff for company. This means the R35 actually has two prop-shafts spanning the gap 'tween gearbox and engine: one taking power from the motor to the transaxle, with another taking power back to the front differential. It all helps to keep longitudinal weight distribution as close to the golden 50-50 mark and it's a trick used by supercars as diverse as the Corvette Z06 and the Ferrari 599 GTB. You'd think such an arrangement would add a lot of weight, but the R35 - like the 350Z - features carbon-fibre prop-shafts to help keep rotating mass and overall weight to a minimum. Still, that doesn't stop it from looking weird.
Speaking of weird, the trainspotter types amongst you will have probably noticed that the R35 features a merged and split exhaust system like the 350Z, instead of a true dual exhaust like the Z32 300ZX. Obviously, the second propshaft precludes the use of a symmetrical dual exhaust, but we have to wonder what kind of efficiency hit the merged design imparts upon the R35. Clearly this is one area that will benefit from an aftermarket solution.
Anyway, there's a bunch of detail shots of the R35 in all it's naked glory over at Nissan's site, so head over and check them out pronto. Not only are there pics of drivetrain and powertrain hardware, but there's also some screen grabs of the Polyphony Digital-designed multifunction display in there. Is the new GT-R a techno-geek's wet dream? You betcha.
