Same with a "tank with spawn engine".. spawn engine!
It's a little buggy in cylinders - pistons often turn in cylinder.
s - for establish link with wheels, i - for engine on, - o for fuel intake.
w - to enable 2wd instead of 1wd. By default only first wheel is connected to engine.
Gear are 2,1,0 on numpad. Be sure you take on only one gear at a time.
Engine works fine with load, but it crashes fastly if not loaded, so make car run as soon as posible after engine starts.
Sorry for my english
