The Engine

A compression ratio of 8.5:1, twin T28 Garrett turbochargers and a large front-mounted intercooler help the RB26DETT produce 280hp at 6800rpm and 360Nm (260lb-ft) of torque at 4400rpm. But actually this engine was directly designed for use in Japanese Group A racing, and tuned derivatives have proven to reliably run with over 550hp without need-ing any internal changes - so look at the tuning-part to really see

what this engine is capable of.

The Transmission

The power is deployed to the wheels via a 5-speed gearbox which is coupled to the Skyline's all-wheel-drive system ATTESA-ETS (Advanced Total Traction Engineering System for All - Electronic Torque Split).

ATTESA-ETS

The GT-R uses an electronically controlled all-wheel-drive system (similar to Porsche's 959). A 16-bit microprocessor monitors the car's movements a 100 times per second, including wheel rotation and lateral as well as longitudinal acceleration. When slip is detected at a driving wheel, the system electronically distributes torque from this spinning wheel to one without slip.

In this case the electronic AWD-system offers the advan-tage that actions are enacted much faster than by a viscous-coupling-system (we're speak-ing of hundredths of a second here). In standard setup, ATTESA-ETS distributes the torque to the rear-wheels, but when slip is detected on one of those rear-wheels, it can distribute up to 50% of the torque to the front wheels, i.e. it can adjust the front/rear torque-split from

anything between 0:100 to 50:50. Among the rear-wheels, an active LSD can further distribute the torque from one wheel to the other if necessary. Due to this setup, the Skyline GT-R can even drift, although it is an AWD car.

The Suspension

The R32 GT-R uses a multilink suspension front and rear. Road-holding and especially the steering is further improved by the Skyline's all-wheel-steering system Super HICAS.

Super HICAS

The Skyline's all-wheel-steering enables the rear-wheels to steer the car with a maximum of one degree. A very complex system compares the car's movements with the driver's input at the steering wheel and adjusts the angle of the steering wheel according to the direction the driver intends to go. The result is a steering that makes the GT-R feel much more nimble than its size suggests.

The V-Spec Version

The Victory Specification version is the most sportive version of the Skyline GT-R. It uses a stiffer suspension and a revised all-wheel-drive system. Additionally the performance is improved by bigger 17inch 225/50 tires and four-pot Brembo brakes with ventilated 324mm discs up front and two pot 300mm Brembo brakes in the back.
