In all, Audi will offer the A3 Sportback with six different engines, half diesel and half gasoline. The model shown here features a new 2-liter turbo diesel, good for 150 horsepower and 236 pound-feet of torque. The most likely engine to be used in the U.S. model would be a gasoline-fueled, turbocharged 1.8-liter. This one makes 180 horsepower and 184 pound-feet of torque. As Audi currently offers a diesel (TDI) A3 in the U.S., the new 2-liter diesel may find its way over as well.
