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.
