Mercedes-AMG is likely to develop a plug-in hybrid version of every model in its line-up in the future, featuring a performance-tuned version of Mercedes-Benz’s EQ Power system.
The move is part of a major push of plug-in hybrid (PHEV) technology being undertaken by Mercedes as a key element of its £9 billion electrification programme to dramatically reduce fleet CO2 emissions. As previously reported by Autocar, the first Mercedes-AMG PHEVs are expected in 2020.
Mercedes-AMG currently offers a number of mild-hybrid models, including the CLS 53 and E53. These feature the firm’s EQ Boost-branded 48V starter/generator, which can deliver an additional 22bhp and 184lb ft of torque. However, the need to meet increasingly tight EU fleet emissions targets means that these are likely to be an intermediary step.
Mercedes' head of external affairs for emissions, Frank Overmeyer, expressed his personal view that: "All the AMG vehicles will be available in the future with plug-in hybrids as an option. Mild hybrid is not the strategy of AMG, because the emissions savings are too small.” Overmeyer is not involved in the management or development of AMG models.
Mercedes-Benz currently offers PHEV variants of the C-Class, E-Class and S-Class under the EQ Power badge, with GLC and GLE versions coming soon. The firm will launch 20 PHEV variants by the end of 2020, with an A-Class using a new plug-in powertrain developed specifically for compact cars due imminently.
The models all feature the firm’s third-generation PHEV system. This uses an electric motor that produces 121bhp and 325lb ft and offers around 31 miles of electric-only range. Mercedes is working to extend that range with the next S-Class, due in 2020, which is expected to use a system that offers 62 miles of zero-emission power.
