e-tron: our fully electric drive technology

Electrification and digitalisation are the big issues of our time. At the same time, they are the key to a more sustainable future. At Audi, electrified cars carry the name e-tron.

What is e-tron?

Motors of the future should provide propulsion without fossil fuels. We therefore look to a particular type of energy that is theoretically available in infinite amounts: electricity. It is stored in batteries embedded in the vehicle floor. If this combination of batteries and an electric motor is used in an Audi, the vehicle carries the name e-tron.

More joy for the driver and the environment

“Battery electric vehicles” (BEV) offer some interesting advantages over combustion engines. They emit no CO₂ locally, and therefore cause less pollution in cities. The urban environment also benefits from the lower noise level of the almost silent electric motor. Usually, only wind and rolling noises are perceptible in the vehicles. The immediate availability of torque means that none of the fun of driving is lost. An e-tron has a clear advantage over most combustion engines when in sprint.

No need to worry about range

If you often have your smartphone in your hand and use it to watch videos or listen to music, you can hardly get through the day on one battery charge. The battery of an electric car empties faster when it’s driven at a sporty rather than a more relaxed pace as well. With e-tron, nobody has to worry about the range. Audi uses high-performance batteries with high storage capacity for long journeys. And even if a stopover is necessary, the batteries’ quick-charge capability means that it’s not long before you’re ready to continue your drive.
