The European model employs a parallel hybrid concept combining a 2.0-liter TFSI gasoline engine delivering 211-horses and 350 Nm (258.15 lb-ft) with an electric motor that produces an output of 33 kW (45 hp) and 211 Nm (155.63 lb-ft) of torque.
Directly mounted behind one another, the four-cylinder gasoline engine and the electric motor have a brief combined system output of 245HP (180kW) and 480 Nm (354.03 lb-ft). A modified 8-speed tiptronic transmission transfers power to the front wheels.
The electric motor draws energy from a lithium-ion battery system, which weighs in at 36.7 kg (80.91 lb) and is located in the collision-protected area under the luggage compartment. Audi says the luggage capacity is 375 liters (13.24 cu. ft), which is significantly less than the regular model's 530 liters (18.7 cu.ft).
What you get in return is a 0 to 100 km/h (62 mph) sprint time of 7.3 seconds and a top speed of 238 km/h (148mph), but more importantly, a combined fuel economy in the European cycle of less than 6.4 liters per 100 km (36.75 US mpg) with CO2 emissions of less than 146 grams per km (234.96 g/mile).
In addition, Audi says that the A6 Hybrid can be driven up to 100 km/h (62mph) under electric power alone.
