Quad-Al Fiat Topolino
This insane car was built by drag racing legend Jim Lytle.
In the 60s you could pick up an Allison V12 for $50-150. Quite the bargain for something that made 3,000HP in stock form.
Jim Lytle had already built an Allison powered car, the legendary Big Al sedan with its single V12 up front. So when he got the idea for the Quad-Al Topolino it was only a matter of time. This mad creation received four of the V12s amounting to 6,840 total cubic inches and 12,000hp. It holds the record for the most powerful piston powered car ever.
Lytle wasn’t done after shoving four V12s into one chassis, he decided it needed four wheel drive, eight tires, and a fiberglass body.
He fabricated all the linkages between the engines himself, and they’re stuffed into a custom chassis built in his own shop. The rear engines are actually canted 15 degrees so that their carburetor linkages line up with the front engines.
I imagine this being quite the adrenaline rush.
This wasn’t the only Fiat that Jim put one of those magnificent Allisons into. He also built a Fiat 600 Multipla with a fiberglass lift off body and a big Allison right smack in the middle.
