Audi is expanding its portfolio in the midsize to the luxury class: The Four Rings will also be offering plug-in hybrids in the A7, A8, Q5 and Q7 model lines. They all bear the “TFSI e” logo. The A6 55 TFSI e quattro* is now continuing this series. Like all Audi plug-in hybrid models, it also combines two highly efficient drives to achieve a system output of 270 kW (367 PS). <br /><br />Its four-cylinder gasoline engine, a 2.0 TFSI, delivers 185 kW (252 PS). The electric motor, which is integrated into the seven-speed S tronic, has a peak output of 105 kW. The system torque already reaches its maximum of 500 Nm (368.8 lb-ft) at a speed of 1,250 rpm. The lithium-ion battery, which is positioned in the vehicle rear, stores 14.1 kWh of energy. It is integrated such that the luggage compartment offers level and convenient luggage space.<br /><br />The A6 TFSI e 55 quattro is a sporty car that is highly efficient at the same time. It accelerates from 0 to 100 km/h (62.1 mph) in 5.6 seconds and has a top speed of 250 km/h (155.3 mph). On purely electric power, it reaches a top speed of 135 km/h (83.9 mph). Its electric range, measured according to the WLTP procedure, is up to 53 kilometers (32.9 mi). Thus the tax rate imposed on it when used as a company car in Germany is cut in half. The powerful plug-in hybrid model is the only premium sedan in the direct competitive environment that has quattro all-wheel drive on board.
