The extending rear spoiler Another innovation is the extending rear spoiler, which for the first time on an Audi has several positions to optimize the various driving modes. This means that in any driving mode the rear spoiler can adjust the direction of the airflow to produce the most appropriate aerodynamics. In eco mode, the slipstream is brought together as close to parallel and to the vehicle’s tail end as possible. The reason? The smaller this low-pressure zone at 1 Audi e-tron GT quattro: combined electric power consumption in kWh/100 km: 19.6–18.8 (NEDC); combined CO₂ emissions in g/km: 0 Audi Report 2020 144 Products & Services the rear, the lower the entire vehicle’s resistance. In the dynamic mode, the rear spoiler is angled much more steeply to reduce lift at the rear wheels to the minimum level required. The adaptive air suspension The controllable features also include the adaptive air suspension. “Height adjustment is important for aerodynamic reasons. The lowest position, the setting for fast freeway driving, is ideal for the drag coefficient,” explains Islam. He then adds: “From an aerodynamics perspective, I don’t mind if the suspension setting is higher for everyday use in city driving. At those speeds, aerodynamics are barely relevant.” He concludes: “The Audi e-tron GT1 has an outstanding drag coefficient of 0.24. That’s the best drag coefficient to date of any of our electric models. Good aerodynamics are especially important for maximizing the electric range. But if performance is what you want, with very low lift for precision driving dynamics, the Audi e-tron GT1 can of course also deliver. The technology makes incredible aerodynamic breadth possible.” Fascinating effects thanks to technological innovation: active adjustment of aerodynamics by the rear spoiler adjustable in two stages.
