The main difference from conventional variants is that the e-Tron S and e-Tron S Sportback have three electric motors (one on the front axle, two on the rear), compared to the configuration of two standard engines. This makes them the first production models in the world with this mechanical configuration.
The front-engine is an adapted version of the rear engine of the Audi e-Tron 55. In S mode, both vehicles offer a maximum power of 503 hp (370 kW) and a torque of 973 Nm for eight seconds, doing 0 to 60 mph in just 4.5 seconds and reaching a maximum speed of 130 mph.
The battery pack continues to be 95 kWh, with 91% (86 kWh) of usable capacity. The autonomy is 223 mile-range(e-Tron S) and 226 mile-range (e-Tron S Sportback), respectively. This slight difference is due to the superior aerodynamics of the e-Tron S Sportback (0.26 Cx), which despite having the same powertrain, enjoys a body with a more pronounced roof drop than the e-Tron S (Cx of 0.28).
The suspension has specific settings. The Audi drive select system offers up to seven driving profiles, acting on the adaptive air suspension, which can vary its height by up to 7.6 centimeters. The tracks are 23 millimeters wide, while the standard wheels are 20 inches, although optionally, they can be equipped with 21 and 22 inches.
