German pocket rocket receives a healthy boost in power from the Audi tuning specialists. Audi aftermarket specialist ABT Sportsline has used the limited-run A1 Quattro for its latest project, working its magic to enhance the car's already potent performance.The 2.0-liter turbocharged four-cylinder engine has been tweaked with an ABT Engine Control and ABT Power Software unit added, increasing output from 256 horsepower and 258 pound-feet of torque to 307 hp and 295 lb-ft. As a result the A1 Quattro is able to sprint from 0-62 mph in just 5.4 seconds, which is three-tenths quicker than the stock model. Source: Carbuzz
