All engines used in the 2019 Audi A7 Sportback come standard with a new mild hybrid system for greater comfort and efficiency. With the two V6 engines, this uses a 48-volt primary electrical system. A belt alternator starter works together with a lithium-ion battery and achieves a recuperation performance of up to 12 kW when braking. At speeds between 34.2 and 99.4 mph, the four-door coupe can coast in freewheeling mode with the engine deactivated and then restarted comfortably via the belt alternator starter .
The start-stop function has been significantly expanded and now activates at 13.7 mph. In combination with the standard front camera, the engine is restarted predictively while at a standstill as soon as vehicle ahead begins to move. In real-world driving, the MHEV technology reduces fuel consumption by up to 0.7 liters per 100 kilometers.
