Best for: interior opulence

Packing a drive battery twice the size of many of its PHEV rivals, this Mercedes-Benz C-Class model has an official electric range of up to 69 miles.

The C300e’s powertrain comprises a 2.0-litre turbocharged petrol engine and a 127bhp electric motor and makes 308bhp in all, in a car that can crack 62mph from rest in just 6.1sec.

It’s available in both saloon and estate bodystyles, importantly with no significant compromise to either passenger or boot space from its extra PHEV hardware.

The C300e impressed our road testers with its refinement and isolation and with its laid-back, luxury-first, Mercedes S-Class-in-miniature vibes.

Keener drivers with less of an eye on their tax bills may probably still prefer to consider the likes of the BMW 330e, but for most fleet drivers and operators, the C300e’s excellent electric range is sure to make it a popular option.
