The electrification of the powertrain has a huge influence on the emissions produced by a vehicle with a combustion engine. Considerable savings are possible in particular in urban use. The variety of approaches ranges from simple P0 mild hybrids with belt starter generators to 48-V systems and high-voltage hybrids. It is likely that in the near future all newly developed vehicles will have powertrains that are electrified to a greater or lesser extent, regardless of whether they have a gasoline or a diesel engine. This will allow end customers to choose the best possible powertrain for their personal requirements. Because of the high efficiency of diesels at low engine speeds and the relatively high cost of their exhaust gas treatment systems, they have not been widely used in hybrid systems. However, our cover story highlights the potential they offer. AVL has equipped a diesel SUV with a 48-V hybrid module to give a P2 configuration. The result was a reduction in CO
