Audi has unveiled the new A6 E-tron, positioning it as one of the most aerodynamically efficient and sleekest electric vehicles on the market. The design plays a key role in achieving a WTLP range of up to 350 miles, with a drag coefficient of 0.21, putting it in line with the Hyundai Ioniq 6 and slightly behind competitors like the Mercedes EQS and Tesla Model S. This focus on aerodynamics marks a significant step forward for Audi, showcasing the brand’s dedication to maximising range and efficiency in electric vehicles.
The A6 E-tron’s advanced aerodynamic design follows in the footsteps of previous trailblazers like the Audi A2 and the Mk3 Audi 100. Audi’s head of development in aerodynamics and aeroacoustics, Moni Islam, emphasised the resurgence of aerodynamics in car design, driven by the shift to electrification. In electric vehicles, a substantial portion of energy is used to overcome air resistance—up to 60% at highway speeds—making aerodynamics more critical than ever in optimising battery usage and extending range.
Islam noted that electric powertrains, with their higher efficiency compared to internal combustion engines (ICE), make aerodynamic improvements even more impactful. EV’s often feature flat underbodies, which are easier to streamline, unlike ICE vehicles that require exposed components for cooling. This allowed Audi’s development team to take full advantage of the A6 E-tron’s design from the outset, thanks to the flexibility provided by the new PPE platform, which also underpins the Q6 E-tron.
Key aerodynamic features of the A6 E-tron include:
- Active grille shutters: When the radiator doesn’t require cooling, flaps in the front grille close, guiding airflow over and under the vehicle to boost range by over seven miles.
- Air curtains: Channels on the front flanks direct airflow around the wheels, optimising interaction with the car’s shape and enhancing efficiency.
- Wheel design: The wheels are aerodynamically optimised to balance airflow and brake cooling, contributing to overall drag reduction.
- Virtual mirrors: Optional slim side cameras replace traditional mirrors, adding up to 4.3 miles of range while improving the car’s aesthetics and performance.
- Air suspension: At speeds above 75 mph, the A6 E-tron lowers by 20mm, reducing drag by streamlining airflow over the car and around the wheels.
- Hidden Gurney flaps: These small flaps at the rear of the floorpan help divert airflow from the rear axle, while mini spoilers on the rear wheels create a still air zone to minimise drag.
Audi’s meticulous attention to aerodynamics in the A6 E-tron not only enhances range but also sets the stage for the future of electric vehicle design, prioritising both aesthetics and performance.
