Nissan GT-R technical details

Posted Oct 28th 2007 12:02PM by Merritt Johnson

The new Nissan GT-R is an engineering playground. We hope to get our chance to play with it soon, but until then, we get pictures. Luckily, Nissan has released detailed images of the GT-R drivetrain and suspension. These reveal some of the alterations made in the GT-R design from prior models. One of the more significant changes is the placement of the transmission. The dual-clutch transmission and combination transfer case sit at the back of the car, coupled to the rear differential (that makes it a transfermissiondiffcase). It makes for more balanced weight distribution with the transmission, rear differential and transfer case counterbalancing the weight of the engine and front differential.

The turbochargers have also changed from Garrett units used in past GT-R models to IHI, a Japanese-owned company. The turbine housings (aka hot side) of the turbochargers are a combined casting with the engine exhaust manifolds. Most likely this is done to save space and for emissions reasons to ensure the catalytic converters are as close to the turbocharger outlets as possible. Each turbocharger is followed by two catalytic converters, making for a total of four. Two intercoolers are also installed, as opposed to one with two inlets, keeping the charged air for each bank of cylinders constantly separated. This is most likely done to ensure precise metering of air.

Talk about having two propeller shafts and a large center/transmission tunnel. I wonder where the fuel tank lies. It doesn't have enough room for a spare tire either.

It uses run-flat tires like BMW.

My guess is it has split fuel tanks under the rear seats on the opposite sides of the rear mounted transmission... its the only place left, there is no fuel tank behind the rear seats.
