At launch earlier this year, the turbocharged 1.4-liter's highest output was rather reserved at 120 horsepower and 148 pound-feet of torque. With two forms of forced induction, the supercharger begins its task at a low rpm, while the turbocharger handles high-end boost. By twin-charging the small gasoline engine, Audi was able to bring its power figures up to 185 horsepower and 184 pound feet-of torque, propelling the A1 from 0 to 100km/h in just 6.9 seconds. By comparison, the Mini Cooper S, a key competitor, is powered by a 1.6-liter turbocharged I-4, making 181 horsepower and 177 pound-feet of torque, with century sprint time of about 6.6 seconds.
Audi packaged the high-end A1 with its seven-speed dual clutch transmission as standard equipment, and power is routed to the front wheels. With a tall seventh gear, the A1 returns a very respectable 40 mpg. All 1.4 TFSI models come packaged with Audi's S line body treatment, 17-inch wheels, and an LED interior light package. The standard electronic limited slip differential keeps both front wheels spinning together by applying brakes to the wheel without traction.
