Mercedes-Benz UK has released official pricing and specifications on the E300 BlueTEC Hybrid, the most efficient E-Class yet. On-the-road prices start from £39,645 for the saloon and £41,435 for the estate, with company car tax rates ranging from 12 per cent.

A 2.1 litre four-cylinder diesel developing 204 hp and 500 Nm of torque joins forces with a 20 kW electric motor (which is mounted within the gearbox to save space) to result in a 0-100 km/h time of 7.5 seconds for the saloon and 7.8 seconds for the estate, whilst top speed is around 230 km/h.

Standard kit includes leather upholstery, Becker Map Pilot Navigation, daytime-running LEDs and 17-inch alloys, although buyers can specify 16-inch wheels at no cost to achieve the lowest possible CO2 and economy figures which, Mercedes says, are 4.2 litres/100km for the saloon and 4.5 litres/100km for the estate. Emissions are 109 and 116 g/km respectively.

UK deliveries are expected to begin in November.
