The job's been done properly here. Rather than electrify one of its older engines, as Volkswagen has with its rival Golf GTE, Mercedes has here developed a much more bespoke unit, a 1,332cc petrol powerplant that manages to put out as much as 218hp. That figure combines the 160hp of this model's 1.33-litre powerplant with a 75kW electric motor linked to a 15.6kWh lithium-ion battery. These power sources collectively generate a pretty potent system pulling power figure of 450Nm. So, not surprisingly, performance is sprightly, 62mph dispatched in just 6.6s en route to 146mph. You have to have front wheel drive and an 8-speed 8G-DCT dual clutch auto transmission. Of most interest to a potential PHEV buyer though, will be this model's projected WLTP all-electric driving range - up to 44 miles (compare that to the 36 mile claim of a rival Golf GTE). Obviously, you won't get anywhere near that figure if you regularly approach the quoted all-electric top speed of 87mph.
An 'Electric' drive programme keeps the car in battery drive unless the accelerator pedal's kickdown function is used. In the 'Electric' programme, the energy recovery level can also be selected via paddles behind the steering wheel. The paddles on the steering wheel enable the selection of five different recuperation levels ('DAUTO', 'D+', 'D', 'D-' and 'D--'). The usual additional 'Comfort', 'Sport' and 'Individual' mode settings are also available. According to the given requirements, the driver is thus able to give priority to electric driving, place the emphasis on driving dynamics or give preference to combustion mode in order to save electric range, for example.
