A hybrid electric variant was also available for the first time in the A6, offering a 2-litre TFSI 211 metric horsepower (155 kW) engine combined with a 45 PS (33 kW) electric motor. Electric power is supplied via 1.3kWh lithium-ion battery, with electric-only range of 3 km for constant 60 km/h (37.28 mph) drive and top speed of 100 km/h (62.14 mph).

The market launch of the A6 Hybrid was scheduled for 2012. However, production of the US model was delayed.
