Hybridization

Audi already has various hybrid models on the market. This year will see the rollout to dealers of the compact A3 Sportback e-tron with its plug-in hybrid technology. The next step will follow shortly – the new models with longitudinally mounted engines.
     
The second-generation modular longitudinal engine mounting system is designed to allow the electric motors to work together with the combustion engines – including the TDI units. Their interaction is tailored to the specific model. Audi has developed a technology matrix incorporating electrification stages through to the plug-in hybrid drive.

The interaction of the TDI with the electric motor offers the developers new freedom, permitting the load point to be shifted so as to benefit both fuel efficiency and emissions. In urban driving, where the TDI nowadays has to handle low loads, the electric motor provides zero-emission power on a local level.
