New Porsche 911 GT3 RSR
The capacity of the well-known six-cylinder horizontally-opposed ‘boxer’ engine has been increased from 3.8 to 4.0-litres. The engine now delivers around 450 bhp (331 kW) at 7,800 rpm, and develops a maximum torque of 430 Nm at 7,250 rpm. The rev limiter of the efficient six-cylinder unit kicks in at 9,000 rpm. The engine features an optimized torque curve, which results in better driveability.
