The Fiat X1/9 was great for a lot of reasons. The tiny Italian two-seater had a unique '70s design, while its mid-engine layout gave it fantastic handling characteristics. One thing the X1/9 didn't get from the factory was power—its four-cylinder engine made just 74 horses when new. But at least one owner solved the Fiat's power issue, and turned his car into a world-beating hillclimb rocket.
Manuel Dondi, the current Touring Car Hillclimb Champion in Italy, brought out his fully prepped X1/9 to the last weekend. The car is very clearly equipped for time attack duty, with a full racing slicks and whole bunch of wild aero.
Additionally, Dondi's X1/9 is propelled by a mid-mounted 300-horsepower Alfa Romeo engine—a drivetrain with more than four times the original power output. As you'll see, the combination makes for a hell of a ride.
Watch below as Dondi pushes his little Fiat to the very edge of grip on the hill.
