Audi will showcase the A3 e-tron plug-in hybrid at the 2013 Geneva Motor Show. The Audi A3 e-tron delivers 150 kW (204 hp) of system power and 350 nm (258 lb-ft) of system torque; projected fuel consumption is 1.5 liters per 100 km (157 mpg US), according to the ECE standard for plug-in hybrid automobiles. This corresponds to CO2 emissions of 35 grams per km (56 g/mile).
The A3 e-tron accelerates from 0 to 100 km/h (62 mph) in 7.6 seconds, and has a top speed of 222 km/h (138 mph). In electric mode, the Audi A3 e-tron reaches a top speed of 130 km/h (81 mph) and has a maximum range of 50 km (31 miles).
The combustion engine is a modified 1.4 TFSI producing 110 kW (150 hp). A clutch links the TFSI to an electric motor with an output of 75 kW. The disc-shaped electric motor is integrated into a newly designed six-speed e-S tronic, which transfers the power to the front wheels.
The two powerplants complement one another. The electric motor delivers its peak torque from start to around 2000 rpm, and the TFSI’s maximum pulling power is available in a range from 1,750 to 4,000 rpm.
The Audi A3 e-tron can be driven with just the combustion engine, just the electric drive or in hybrid mode. The driver can choose to have both powerplants active at the same time (“boosting”). When the driver lets up on the accelerator, they both deactivate temporarily (“gliding”). In this way motor braking torque is eliminated and efficiency increases.
