The electric drivetrain with 3-motor-layout
of the new Audi e-tron top model
Das elektrische Antriebssystem mit 3-Motor-Layout
im neuen Audi e-tron Top-Modell
Abstract
With the e-tron top model, Audi is the first high-volume manufacturer to put a BEV with a
3-motor layout and active electric torque vectoring into mass production, completing its
scalable electrical drivetrain system for the e-tron series.
The drivetrain kit for the Audi e-tron and e-tron Sportback thus comprises two battery vari-
ants (71 kWh and 95 kWh) with flexible cell technology (prismatic/pouch) and four electric
axle drives with system power outputs between 230 and 370 kW.
Forty years after the launch of the mechanical quattro drive in Geneva in 1980, the new
electric twin-coax rear axle of the Audi e-tron top model is a real technical highlight. It is
capable of applying several thousand newton metres of yaw moment to the vertical axis of
the vehicle, enhancing the dynamics of the e-tron to a highly sporty level. The outstanding
electric quattro drive of the Audi e-tron has been significantly improved once again as a
result.
