Mercedes-Benz is following in BMW (BMW i) footsteps with the creation of a sub brand specifically for its plug-in vehicles.
M-B says that beginning this Summer, two sub brands will be put into use. EQ Power will be the brand under which Mercedes will sell its plug-in hybrids and EQ Power + will be the designation used on AMG (performance division) plug-in and conventional hybrids released by M-B.
As Auto Express explains:
"All standard Mercedes plug-in hybrid cars will gain the EQ Power designation from the launch of the upcoming facelifted S-Class onwards, which we expect to arrive this summer. High performance Mercedes-AMG hybrids will carry the EQ Power+ designation as used on this year’s F1 challenger, christened the Mercedes-AMG F1 W08 EQ Power+."
Though M-B doesn't expressly states that AMG EQ Power + models will be of the plug-in variety, how many performance hybrids exist that don't plug-in?
Auto Express says that we should see the first EQ Power + AMG model launch in 2018.
Of course, all of this leads up to the launch of the first long-range, pure electric SUV from M-B. This mid-sized crossover with range of more than 300 miles will launch in 2019, or perhaps even sooner.
Further down the road, M-B says that at least 10 BEVs will carry the EQ Power designation by 2025.
