The recuperation system contributes to the electric SUV’s range. It involves both the two electric motors and the electrohydraulically integrated brake control system. For the first time, three different recuperation modes are combined: manual coasting recuperation using the shift paddles, automatic coasting recuperation via the predictive efficiency assist, and brake recuperation with smooth transition between electric and hydraulic deceleration.
Depending on the driving situation, the Audi Q8 e-tron decides whether to decelerate via the electric motor, the wheel brakes, or a combination of both – and does so individually for each axle. When braking from higher speeds, the system recuperates with around two-thirds of its drive power.
The animation explains the brake-by-wire system of the Audi e-tron.
This technical animation shows the function of brake blending and recuperation in the Audi Q6 e-tron. Around 95 percent of all braking processes in everyday driving can be covered by recuperation and thus contribute to the efficeincy and range of the vehicle.
This animation illustrates the composition and function of the "digital stage" in the Audi Q6 e-tron with the curved MMI panoramic display and the optional MMI front passenger display and augmented reality (AR) head-up display (HUD).
The technical prerequisite for the efficient recuperation properties in the Audi Q8 e-tron is the brake-by-wire braking system – it completely decouples the brake pedal and brake hydraulics. When the driver presses the brake pedal, the system calculates whether the generators’ recuperation power is sufficient for the desired deceleration or whether it’s necessary to use the disc brakes on the front and rear axles.
