400-HP Audi One-Off Is A City Car On Steroids

/ Comments

So much power in a little body is a recipe for fun.

ABT Sportsline is one of the world's best-known Volkswagen and Audi tuners responsible for building some incredibly powerful vehicles. The company recently turned its sights on a trio of V6-powered Audi models including the A6 sedan, A7 Sportback, and Q8 SUV and brought the output of the RS5 up to over 500 horsepower.

In its latest project, ABT built a hotter version of the Audi A1 city car, a vehicle we don't receive here in the United States. Audi is currently working on a hotter S1 of its own but ABT beat the automaker to the punch by tuning the 1.4-liter turbocharged engine from 197 horsepower and 236 pound-feet of torque to 236 hp and 266 lb-ft. 236 hp is plenty for a city car but ABT wanted to take things a step further but dropping in a 2.0-liter engine from a TT Cup race car - the results are staggering.

The motorsport-spec 2.0-liter TFSI engine already produced 310 hp with an overboost function to bring the power up to 340 hp. ABT managed to squeeze out even more juice, bringing the total output to 400 hp and 295 lb-ft, which sounds monstrous coming from a straight-pipe exhaust system. To match the lunacy under the hood, ABT has made the little A1 look equally bonkers on the exterior. It now sits on 19-inch forged aero wheels, is 2.1 inches wider at the rear, and features custom fender flares, hood, mirror caps, and a rear diffuser.

Topping it all off is an eye-catching two-tone livery that appears red on one side and black on the other. The interior has also been customized with new racing seats, tons of Alcantara, and a rear seat delete. ABT didn't say how much all of these modifications would cost because this one-off A1 is not for sale. We assume the amount of work and time invested in the project was massive and this little Audi would probably cost as much as some supercars.
