More power and sharper handling in new GT3


Porsche’s second generation 911 GT3 Model 997, which debuts at the Geneva motor show in March, gets a bigger, more powerful, engine and double its predecessor’s aerodynamic downforce

The six-cylinder boxer motor increases to 3.8-litres (from 3.6) and is 15kW more powerful, at 320kW. Porsche has improved cylinder head breathing by adding VarioCam to the exhaust camshafts. The engine also develops better torque at medium revs.

The 0-100km/h time improves, to 4.1 seconds, and the GT3 will hit 160km/h in 8.2 seconds and reach a top speed of 310km/h.

Porsche has retuned the Porsche Stability Management (PSM) system for greater sportiness. The driver can now deactivate both Stability Control (SC) and Traction Control (TC) in separate steps.

Neither is reactivated automatically, even during extremely hard driving; they come back on only when the driver presses a button.

Porsche says aerodynamic improvements result in front and rear downforce that is more double that generated by the previous 997 GT3.

Visual changes include Bi-Xenon headlights, LED rear light clusters, and modified air intakes and outlets.

The Porsche Active Suspension Management (PASM) system has allowed even stiffer springs and anti-roll bars for more precise handling in the selectable sports mode. In normal mode, the PASM provides a comfortable ride for everyday use.

The GT3 rides on new, lighter wheels in a racing-inspired design – with a centre locking nut – fitted with ultra-high performance (UHP) tyres. A tyre pressure monitoring system is standard.

The brakes have larger discs and an aluminium cover to reduce unsprung weight. Better brake ventilation gives consistent stopping power over long periods. Ceramic Composite Brakes (PCCB) made specifically for the GT3 are an added-cost option.

For racing the new 911 GT3 can be fitted with Porsche Active Drivetrain Mount (PADM) engine mountings. They recognise a particularly sporting, race-like style of driving, and make the normally elastic engine mounts harder and particularly resistant to flexing.

An optional lift system for the front axle can increase ground clearance of the car, at the touch of a button, for driving on bumpy surfaces or steep gradients.
