Mercedes E-Class hybrid

The Mercedes E 300 de diesel and E 300 e petrol plug-in hybrid models are on sale in the UK now, going up against the Volvo S90 T8BMW 530e and Audi A6 TFSI e. You can read our full review of the model line here.

The models aim to offer zero-emissions capability for short-distance and urban driving, courtesy of a 122bhp electric motor and 13.5kWh battery, with the convenience of a 208bhp 2.0-litre petrol engine (in the E 300 e), or a 191bhp diesel engine (in the E 300 de).

Both the E-Class plug-in hybrid (PHEV) models fall into the same low, Benefit-in-Kind company-car tax band, and are exempt from the London Congestion Charge. However, neither model has a long enough pure-electric range to qualify for the government plug-in car grant.

Prices for the diesel start at £47,780 for the saloon and £49,780 for the estate in entry-level SE form, rising to £50,280 and £52,280 respectively for AMG Line trim. The petrol E 300 e is only available as a four-door saloon, and costs from £47,530 for the SE and £50,030 for the AMG Line.

Claimed zero-emissions ranges for the E 300 de saloon and estate are 34 and 32 miles respectively, while the E 300 e petrol saloon claims 31 miles of pure-electric running. Mercedes says a typical 7.4kW home wallbox charger will replenish the car's battery from 10 to 100% capacity in under two hours, while a three-pin domestic plug will do the same in four hours.

Claimed fuel efficiency is up to 202mpg and CO2 emissions for the four-door diesel saloon stand at 39g/km, while the estate emits 42g/km. The petrol E-Class hybrid saloon manages 135mpg and emits 47g/km of CO2. Performance-wise, the 0-62mph sprint takes 5.9 seconds in the diesel saloon (a tenth longer for the estate), and 5.7 seconds in the petrol.

SE and AMG Line trim levels are offered, with the base spec including blind-spot assistance, a widescreen cockpit, four USB ports, illuminated door sills, split-folding rear seats, active parking assistance with front and rear sensors, a seat comfort package, 64-colour ambient lighting, 18-inch alloy wheels, keyless go and heated front seats.

AMG Line adds sporty exterior bodystyling, a different design of 18-inch alloys, 'Artico Dinamica' leather upholstery, an AMG steering wheel with touch controls and privacy glass.

There are also option packages: the Premium Pack adds Mercedes' COMAND Online infotainment system, wireless charging; multi-beam LED lights and a 360-degree parking camera, while the Premium Plus pack adds a Burmester surround-sound stereo, hands-free access, a powered boot and a panoramic sunroof.

The Night Pack, meanwhile, includes high-gloss black alloy wheels and various pieces of high-gloss black and chrome exterior trim. Then there's the Comfort Pack, which is only available in conjunction with the Premium or Premium Plus packs. It includes air suspension and (on AMG Line only) Napa leather.

Driver assistance systems can be added by specifying the Lane Tracking pack (which includes active lane-keeping assistance) or the Driving Assistance Pack, which adds active braking assistance, Mercedes' DISTRONIC active cruise-control system, active speed-limit assistance, active lane-changing assistance, evasive steering assistance and various 'Pre-Safe' systems that prepare the car if an imminent impact is detected.
 
In addition to the diesel-electric and petrol-electric plug-in hybrid E-Class cars, Mercedes also offers a diesel-electric C-Class (the C 300 de) and petrol-electric S-Class (the S 560 e), to take on rivals including the BMW 3 Series plug-in hybrid and BMW 7 Series plug-in hybrid respectively.
