At speeds of around 100 km/h and above, drag accounts for more than 50 percent of a vehicle’s total energy demand. Every reduction in the drag coefficient brings a direct improvement in consumption and range. At 0.24, the A2 e-tron 140 kW with the efficiency package has the best drag coefficient among Audi’s compact models and makes the most of this advantage.
Its body follows the principles of streamlined design: a rounded front end, a flowing roofline, and a sharply defined rear. This design reduces drag compared with a conventional fastback model. Further detail solutions at the front flanks include air curtains — channels that redirect airflow to suppress turbulence — as well as gap reducers and gap breathers, which calm the air around the wheel arches.
The Audi A2 e-tron features an active cool-air intake that stays closed during normal driving and at higher speeds to reduce drag and optimize range. During charging, rapid acceleration, or in summer heat, the active cool-air intake opens to protect the battery and electronics.
