RX 2160

The RX 2160 was a highly efficient engine secretly developed during WWII by Bent Cranium under orders from Erwin Rommel to provide a stronger powerplant for the Nazis' prototype super tanks in the face of a shortage of petrol supplies. At the time that he had developed the engine, Cranium was a young engineering prodigy.

It was only seen during a flashback in the 1999 Speed Racer three-part comic book miniseries by WildStorm.

Trivia

 * On the cylinder head, the engine's designation is stylized with Roman numerals as RX MMCLX. MMCLX means "2160" in Roman numerals.
