Summary

In 2024, Audi will launch the so-called Premium Platform Combustion (PPC). To this end, conventional drives as well as hybrid powertrains are being comprehensively further developed at Audi. In addition to complying with future legal emission limits, increasing performance and comfort, while at the same time reducing fuel consumption, are key development goals.

The new 3.0l V6 TFSI EA839evo represents the logical evolution of the V6 TFSI EA839- engine, which was launched in 2015. Newly designed exhaust gas turbochargers with variable turbine geometry, indirect charge air cooling, DoE-supported optimisation of charge exchange, Miller combustion process and fuel injection system form the basis for achieving these ambitious goals. The engine develops a full torque curve of up to 550 Nm and a nominal output of 270 kW (367 hp). In combination with the 48V mild hybrid system with powertrain generator offered in Europe, very attractive characteristics are achieved in terms of driving dynamics, comfort and CO₂ emissions.

The V6 TFSI EA839evo generation will go into series production in 2024 – initially as a 3.0 litre mono-turbo. It forms the high-performance basis for future S and RS models at Audi and will also be used in other Group models at a later date.
