Audi A3 Sportback e-tron

Audi is working intently to electrify the drivetrain using plug-in hybrid technology. One highlight at the 2013 International Motor Show in Frankfurt that is ready for series production: the Audi A3 Sportback e-tron.

An eye-catcher that will turn heads

The A3 e-tron is a true Audi. With 150 kW (204 hp) of system output and 350 Nm of system torque, it sprints from 0 to 100 km/h in 7.6 seconds before going on to a top speed of 222 km/h. According to the ECE standard for plug-in hybrid cars, the five-door model consumes on average just 1.5 litres of fuel per 100 km – equivalent to CO2 emissions of 35 grams per km. In all-electric mode, the Audi A3 e-tron has a top speed of 130 km/h and an electric range of up to 50 km.

Dynamic or efficient? Why or?

The Audi A3 e-tron is designed as a parallel hybrid – a highly efficient concept. The combustion engine is a modified 1.4 TFSI, which produces 110 kW (150 hp) and 250 Nm of torque. The TFSI operates in tandem with an electric motor that develops 75 kW and 330 Nm of torque.

 

The disc-shaped electric motor is integrated into an all-new six-speed e-S tronic, which transfers the power to the front wheels. The two powerplants complement each other – the electric motor develops peak torque right from start to around 2,000 rpm; the TFSI delivers its maximum pulling power in a range from 1,750 to 4,000 rpm.

 

Accelerating releases energy. Braking recovers it. When braking, the electromechanical brake booster ensures that as much kinetic energy as possible is saved in the form of electrical energy in the battery.

Family car or time machine?

The Audi A3 e-tron’s energy store is a lithium-ion battery system installed in a space-efficient, crash-protected location in the floor, beneath the rear seat bench. The high-voltage battery, inside a housing made mainly from aluminium, has a capacity of 8.8 kWh.

 

A liquid cooling system with its own low-temperature circuit keeps the battery in the optimum temperature range. This sophisticated technology is the key to the power and stamina of the electric drive unit, which remains available at low ambient temperatures.

 

The power electronics are housed in the engine compartment of the Audi A3 e-tron. These convert the direct current from the battery into alternating current to power the motor. The compact unit, with integral DC/DC converter to power the 12V electrical system shares the same cooling circuit as the battery and the charging device.

The charging connection is located behind the four rings in the radiator grille; the cover of the charging socket, like the TFSI engine, sports an e-tron badge. The high-voltage battery can be fully charged in just over two hours with a 3.6 kW charger.

All relevant components within the high-voltage network of the A3 e-tron have no conductive connections to other parts of the vehicle. If the seat belt tensioners or airbags are triggered in an accident, the entire system is immediately disconnected from the power supply.
