Interesting question! I think it's two-strokes that scale best. The company Wärtsilä builds 14 cylinder diesel two-strokes that generate 80,080 kW of power. They are used in cargo ships.
EDIT: Oh, "used in cars". I misunderderstood the question.
A two stroke marine diesel is very different from a gasoline two stroke. Only intake is done through the cylinder wall ports and exhaust is through poppet valves at the top. (Uniflow) Also lubrication is done like in four strokes. There is no crankcase compression, instead turbochargers are used.

I did not know of those engines. Very interesting. That does win the question, given how you just can out scale a cargo ship. :)
