DOHC on modern engines.
Most of the engines from Audi and Mercedes in use today are DOHC engines with rocker arms.
From what I have read, the reason is a smaller lift on the cam lobe, thus a smaller max cam diameter.
This uses less power (lower inertia) to turn the cam.
And also, the rockers are always roller equiped, reducing friction.
This system on some Audi v8 5 valve engine uses only one cam lobe on the intake side, not 3, reducing cost and weight of the cam.
Is this something that will be in the game, eventually?
