The petrol plug-in hybrid in this E 300 e combines a 1,991cc four-cylinder producing 211hp with a 122-hp electric motor, good for a system output of 320hp and 700Nm. With its 13.5-kWh capacity the battery provides an electric range between 49 and 53 kilometres. Official CO2 emissions are 41g/km, putting it in the same league as the E 300 de plug-in diesel, which produces 306hp and 700Nm of torque with standard emissions of 36g/km. This makes both models particularly appealing from a tax point of view.
In terms of performance, the petrol and diesel versions of the plug-in also barely differ, as they accelerate from 0 to 100km/h in 5.7 seconds and 5.9 seconds, respectively. Yet there is a difference: the petrol version is significantly quieter than the diesel when the combustion engine kicks into action.
