I am mistaken. However they are more powerful then most comercial Lorrys
However if you had 5 335d engines you would get 15 litres 30 cylinders and 3500nm of torque with around 1600bhp. Quite some thought.
I still like the thought of aero engines cars of the 20's and 30's how about a RR Merlin engine developing around 2000bhp when supercharged. I think that's 16+ litres.
