Citroen did it with the 'sahara' 2cv
I read an article on the Mercedes-Benz A190 Twin the other day, it is fitted with two 125 hp 1.9 engines, one in the front and one in the back. It was built by Mercedes in 1999 as a one-off for Mika Häkkinen.
Because of this, I started to think about what other car factories has made twin-engine cars, either as one-offs, prototypes, race cars or simply production models. I could only think of three, which I'll post here. What other cars were out there?
Mercedes-Benz A190 Twin
Citroen 2CV Sahara, it featured another engine and transmission in the trunk, for 4wd traction.
Gear changes for the front and rear transmissions were operated by a common central shift lever, simultaneously moving the two sets of selector rods; the rear rods could also be disengaged, thereby enabling the Citroen to be driven by only the front engine as a two wheel drive car. Sahara production started in December 1960 and ended in 1971 after 694 vehicles had been built,
The Golf Pikes Peak, a true rally car made for the famous hill climb.
