1953 Timossi-Ferrari ‘Arno XI' Racing Hydroplane is literally unique. Being built the beginning of the 50's this one-of-a-kind hydroplane Ferrari is powered by a twin-supercharged 4.5-liter Ferrari Tipo 375 F1 V-12 engine.

Moreover, this powerful V12 is equipped with twin four-barrel carburetors. And if you wonder about the horsepower it produces, well … can you even imagine that an engine which is built in the middle of the last century can produce more than 600 horsepower?

To be hones, at first I couldn't. But there were some videos recently made, which prove that this is in fact true. Take a look at one of them below, and see and hear for your own self how powerful this engine sounds.

This achingly beautiful and historic Ferrari was recently sold for $1 124 060 in RM Auctions' Monaco sale. It weighs less than 1764 pounds and has been restored for the sale.
