The Porsche 911 GT3 Cup S has been replaced by this new model – the Porsche 911 GT3 R, adding yet another variant to the neverending list of different 911 GT3 models. No matter what kind of 911-beating laptimes Nissan posts with its GT-R, the choice of plenty of small racing teams most of the time is the 911 GT3.

The GT3 R’s 6 cylinder boxer engine has a displacement of 4.0 litres, up from the 3.8 litres you get with the road cars or the Cup model. This same engine size is also found in the 2009 GT3 RSR. The 0.2 litres of extra displacement has been achieved by increasing the cylinder stroke to 80.4mm instead of 76.4mm.


The engine is mated to a 6-speed sequential dog-teeth gearbox. Dog-boxes use gears that are straight-cut instead of the helical-cut gears that we have in our normal road car manual transmissions. Because of the different way the gears engage, a dog-teeth gearbox is much more noisy (that whirring sound that we get when we travel in reverse gear – they have it all the time!), and they also don’t have synchro rings so you basically just slam it with greater force into engagement instead of having to clutch at changes. A dog box has less transmission losses compared to a helical gearbox and is more durable.

Porsche’s focus with this new model is better drivability and easier handling. The GT3 and its race-going variants have always been hardcore cars but this car has ABS, traction control and a throttle blip function built into its e-gas throttle body. These features make it more suitable for an ambitious amateur racer (with deep pockets – the car is 279,000 Euros) to drive the car.
