The Audi A3 is offered as a sedan, convertible, or 5-door Sportback. Available engines include a turbocharged 1.8L unit that produces 170 horsepower and 200 pound-feet of torque. This engine sends power to the front wheels through a 6-speed dual-clutch gearbox. A 2.0L turbodiesel (TDI) engine making 150 horsepower and 236 pound-feet of torque is a fuel economy hero in the A3 range, and Audi estimates 36 mpg in combined city and highway driving for the TDI. Like the 1.8 engine, the 2.0L TDI sends power to the front wheels through a 6-speed dual-clutch transmission.
A 2.0L turbocharged gasoline engine makes the A3 a little bit speedier, with 220 horsepower and 258 pound-feet of torque. Unlike the 1.8 and TDI versions, any A3 powered by a 2.0L gasoline engine sends power to all-four wheels via quattro all-wheel drive. A high-performance version of this same engine powers the Audi S3, where it makes 292 horsepower -- enough to go from 0 to 60 mph in 4.7 seconds.
Finally, the A3 Sportback e-tron hybrid utilizes an electric motor that makes 102 horsepower and 243 pound-feet of torque, plus a 1.4L turbocharged gasoline engine capable of 150 horsepower. When combined, the two powerplants make 204 horsepower, making it one of the most powerful hybrids available. The Sportback e-tron can drive on purely electric power for about 17 miles,
