At this year’s Geneva Motor Show, Audi will bring the A3 e-tron, an electrified version if its popular hatchback. According to the official press release, the A3 e-tron is powered by a 1.4-liter TFSI engine delivering 150 hp (110 kW).
Moreover, the vehicle uses also an electric motor that produces 75 kW or 100 hp. 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 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.
Audi A3 e-tron is capable to hit 100 km/h (62 mph) in 7.6 seconds and has a top speed of 222 km/h (137.94 mph). The five-door model needs only just 1.5 liters of fuel per 100 km (156.81 US mpg), which corresponds to CO2 emissions of 35 grams per km (56.33 g/mile).
Using just electricity, the A3 e-tron has a maximum range of 50 km (31.07 miles) and a top speed of 130 km/h (80.78 mph). What is more interesting is that 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.
Audi revealed that there will be three modes under the A3 Sportback e-tron. What this means is that it can be driven using the combustion engine alone, the electric drive, or both with the hybrid mode. Drivers who opt for the electric mode need not worry as it continues to deliver powerful acceleration even if the TFSI is not used. Still, the driver will always have the ability to use the two powerplants at the same time, also called as boosting.
Should the driver stop pressing on the accelerator, both powerplants are immediately deactivated, known as gliding. Because of this, the braking torque of the engine is removed, which means the efficiency in heightened. The three driving modes can be selected through the selector lever of the e-tron and the EV button. The S plane stands for sporty, with the D program ensuring that the vehicle runs efficiently, and the EV clearly refers to electric mode.
On the inside the A3 Sportback e-tron has a display concept which shows the precise information of the model’s drivetrain status. For its instrument cluster, the overall system power is no longer shown on the standard rev counter but on the powermeter. In addition, the instrument cluster now displays the battery’s charge status.
Meanwhile the color display of the driver information system, as well as the MMI navigation monitor, is where the driver can see the power flows of the drivetrain and the consumption figures and operating ranges of both the gas engine and electric drive. A feature in the A3 Sportback e-tron is the electrified brake servo which helps to recover energy while braking.
There is a vacuum brake servo with an electric vacuum pump serving as that extra supply connection. Further the hybrid management has been tuned responsively with the model’s electric motor.
With the moderate braking forces, the electric motor now functions as an alternator. Thus, it supplies much of the retardation while recovering majority of the energy used. It is then transmitted back to the high-voltage battery. For the wheel brakes, these are only activated if the brake pedal is pressed with more force.
