Audi’s new A6 Avant features MHEV plus mild hybrid technology for both the 2.0 TDI diesel four-cylinder with 150 kW (204 PS) and the 3.0 gasoline TFSI six‑cylinder with 270 kW (367 PS).

The MHEV plus system supports the combustion engine, increases performance and driving comfort, and reduces carbon emissions. The system consists of three main components: a 48-volt battery, the belt alternator starter (BAS), and the powertrain generator (PTG) with integrated power electronics.

2.0 TDI (150 kW) quattro ultra powertrain with 48 volt MHEV plus technology.

The PTG enables fully electric parking and maneuvering. The A6 Avant also runs on electric power when driving slowly in the city, in slow-moving traffic, or outside city limits when coasting to the next stop. The PTG produces additional torque up to 230 N·m and up to 18 kW (24 PS) of power when starting off or overtaking. When decelerating, the PTG can recover up to 25 kW of energy.

Orders for the new Audi A6 Avant can be placed as of March 2025. The entry-level engine TFSI 150 kW will start at 58,000 euros. The 2.0 TDI with MHEV plus technology will start at 61,700 euros. The first vehicles will be delivered to customers at the end of May 2025.
