The Next Audi 48V Hybrid Powertrain Generation with an Integrated Electric Drive System

The new MHEV plus system based on a 48-volt on-board electrical system supports the combustion engine and reduces CO2 emissions while increasing performance. The powertrain generator (PTG) enables partially electric driving that contribute to a reduction in fuel consumption.

The PTG can also add up to 18 kW (24 PS) of electric power to the output of the combustion engine. When decelerating, the PTG feeds energy back into the battery (recuperation) at up to 25 kW. As a result, purely electric maneuvering and parking are possible to a limited extent. Thanks to the option of using an electric air conditioning compressor, the air conditioning system can also be operated when the vehicle is stopped at traffic lights and the combustion engine is switched off.

With the integrated and blending-capable brake control system (iBRS), the brake pedal and the brake hydraulics can be completely decoupled. In models with the MHEV plus system, for example, it achieves the necessary deceleration without using the friction brakes thanks to regenerative braking. This means that deceleration is initially achieved solely by recuperation. The friction brakes only kick in when the brake pedal is pressed harder. The brake feel remains unaffected by this.

  1. these look awesome.

    doesnt that cable junction look like it is situated right above the catalytic onvertor.

    you know. literally the hottest zone, outside of the combustion chamber?

    whats frustrating to me, is that toyota has had the prius on the market since 1997.

    and people like me have been BEGGING for a hybrid manual diesel

    (likened to a 5speed manual honda insight)

    and so now. manufacturers are building, basically, a prius.

    because they realize that when people go buy an EV. they want a tesla.

    the year is 1997. toyota releases the Prius.

    its now 2024, and we are seeing 48V hybrids.

    oh hey audi. did you tell them about the timing chain on the back of the engine?

    you know. the one that requires engine removal to ‘service’

    LOL
