Mercedes-Benz C-Class C300e 2021 UK review

The most economical new C-Class variant comes with over 60 miles of EV range and could be an excellent counterpoint to the less refined, more engaging 330e Perhaps you’ve always liked the plug-in hybrid idea but so far they’ve made little sense for you as an individual.You’re certainly not alone: with any PHEV, it’s possible to save magnificently on fuel costs, but only if your driving habits fit a very specific pattern of behaviour. If they don’t, the meagre electric range of most PHEVs starts to feel pretty nominal and the heavy battery pack becomes an ornament that drags down the efficiency of an engine forced to work harder than necessary. All pretty contradictory.However, with this new Mercedes C300e, the technology is coming of age. The plug-in C300e has an official electric range of 62 miles, almost double that of the outgoing version. By comparison, the otherwise excellent BMW 330e musters only 37 miles and there will be no PHEV Audi A4 until at least 2023. So if you want a premium saloon that you can use as freely as an EV during the week but has proper ICE legs for longer journeys, the C300e is your most promising option, and the estate version will only enhance the breadth of its appeal.The layout is familiar, with charge for the electric motor supplied by a 25.4kWh battery pack beneath the stepless boot f loor. The pack can be replenished fully in half an hour at charging speeds of up to 55kW and the 127bhp motor it drives is integrated into the nine-speed automatic transmission.Four-wheel drive is likely to follow, but at first the C300e will be rear driven, with its motor assisting a 201bhp 2.0-litre four-cylinder petrol engine that can propel the car alone. Total system output is 8bhp down on before but still generous at 308bhp.
