For the first time, the engine in the 911 GT3 is equipped with enhanced VarioCam.This improved system not only adjusts the camshafts on the inlet side according to engine speed and load, it now also controls the exhaust camshaft – for even more power and torque. The continuous valve timing adjustment is performed by a rotary-type adjuster on each camshaft. VarioCam is an engine control concept that distinguishes between different load scenarios and adapts to the corresponding power requirement.

The adjustment is performed seamlessly by the Motronic® ME7.8.2 electronic engine management system. This enables smoother running characteristics, better fuel economy, lower exhaust emissions and, most important of all, added power and torque across the entire engine speed range.
