If you happen to’ve ever been to Ferrari’s Museum in Maranello, you will have come throughout an engine not like another from Ferrari’s historical past; a tiny, 1.3-liter three-cylinder two-stroke engine that’s supercharged. Sure, a three-cylinder, nothing just like the V8s and V12s which Ferrari builds solely these days for its highway vehicles.
On this video from Drive Tribe, we uncover that Ferrari constructed this compact three-cylinder again within the early 1990s as a take a look at mattress for a two-stroke six-cylinder.

Though two-stroke engines have largely fallen out of favor resulting from their inefficiency and slim powerband, Ferrari’s was a bit of totally different. It used twin-port gasoline injection slightly than a carburetor like a standard two-stroke, in addition to exhaust valves managed by a camshaft. As for the supercharger, it helped to beat a number of the pitfalls of a two-stroke by pumping extra air into the cylinders whereas additionally serving to to flush out the exhaust gasses, growing the effectivity of combustion.
It stays unclear simply why this Ferrari engine by no means made it to manufacturing. The presenter believes that on the time, there wasn’t the best expertise to make sure such an engine could be clear sufficient. It additionally wouldn’t have had sufficient energy for a Ferrari as, in three-cylinder type, reportedly produced simply 130 hp. Nevertheless, it’s claimed the Italian automaker did think about turbocharging it so it may ship upwards of 216 hp, which might double to 432 hp as a six-cylinder.
