Presence requires a strong foundation. On the 911
The engine comes in two power levels. In the 911
By deploying larger turbochargers and electronics further optimised for performance, the 911
Despite achieving an increase in performance compared to the previous generation, fuel consumption and CO2 emissions are remarkably low.
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 lightweight metal design with integrated dry sump lubrication. Forged connecting rods are used as well as forged aluminum pistons moving in cylinders made from an aluminum/silicon alloy.
Together these help deliver the 911
