Summary

With its next generation of the V8 TDI engine, Audi is implementing a completely new engine design concept featuring sequential turbocharging in the inner V in combination with an electric powered compressor (EPC). This 4.0l engine is a new highlight of Audi TDI technology. The newly developed engine will have its world première in the Audi SQ7. It combines low fuel consumption with high dynamism and sporty response across the entire revs range. The new V8 TDI engine develops its power from a 3,956 cc capacity. The two turbochargers follow the sequential turbocharging concept. A global first is the electric powered compressor, which assists the conventional turbochargers and delivers highly dynamic starting-off performance among other benefits. The EPC delivers the charge pressure necessary for dynamic power response very rapidly.
