Presence requires a strong foundation. On the 911
The engine comes in two power levels: in the 911
This superior performance is especially remarkable contrasted with the fuel consumption and CO2 emissions values. These are comparatively lower. This is the result of technologies that make efficient use of fuel. In addition to direct fuel injection and VarioCam Plus, a system that controls the camshafts on the inlet side and controls valve lift, the measures responsible include the auto start/stop function and the coasting function.
Another important factor is that the low engine weight relative to its high output benefits both agility and fuel consumption.
The engine features a light-alloy construction with integrated dry sump lubrication. Forged connecting rods are used as well as forged aluminium pistons moving in cylinders made from an aluminium/silicon alloy.
Together, these help deliver the 911
