Mercedes-Benz E 300 e 2021 Add To Compare Remove From Compare Vehicle Description Contact The Mercedes-Benz E-Class is no stranger to this award, having picked up the gong in this category last year with a two-pronged plug-in offering. Updates to the car for 2020 have only added to its appeal, so with the petrol-powered E 300 e and the turbodiesel E 300 de, the Mercedes E-Class is once again our Premium Hybrid Car of the Year. We’ve already covered the tweaks this 2020 E-Class received, making it our favourite executive model, while the plug-in powertrains are superbly refined, thanks to the electrical assistance they offer, taking the load off the engines and adding to the relaxed ambience inside the cabin. The stats are impressive; the E 300 e combines a 2.0-litre four-cylinder turbocharged petrol engine with a 13.5kWh lithium-ion battery and electric motor set-up for a total of 316bhp. That’s as much as the Honda Civic Type R that won our Hot Hatchback award. The E 300 de uses a 2.0-litre diesel engine combined with the same battery and motor set-up for slightly less power, at 302bhp, but the same 700Nm of torque, so both machines are much faster than you might think. However, this class is about efficiency and a little luxury, rather than outright speed. Both models will cover 34 miles on electric power alone and travel at up to 30mph in electric mode, but they work best if they’re left to their own devices, when the electric motor assists the combustion engine to keep things quiet and give an instant boost to the acceleration Mercedes-Benz E 300 de AMG Line Edition (£47,480) The diesel PHEV option is still the best choice, offering easy motorway cruising performance, with zero emissions around town. It gets the level of equipment you would expect at this price, too, with twin 12.3-inch screens, the latest connectivity, heated seats, wireless phone charging and lots of safety technology Three petrol and one diesel mild hybrid, four Plug-In versions The engine range includes two Plug-In Hybrid versions (E 300 e, E 300 de, both with rwd or awd), three petrol engines all with mild hybrid (E 200, E 300 and E 450, the latest standard with 4Matic) and three diesels (E 200 d, E 220 d 4-cylinder, E 400 d 6-cylinder and all-wheel drive). The M 254 turbo 2 liter 4-cylinder engine from E 200 and E 300 has an integrated alternator starter with 14 HP and a 48V network. In the E 450 4Matic, the M 256 engine with 3 liter 6-cylinder in line and 367 HP makes its debut in the E-Class range, with integrated alternator starter of 22 HP and 48V network. And the cherry on top is represented by the two AMG versions: AMG E 53 (435 hp, mild hybrid), AMG E 63 (571 hp) and AMG E 63 S (612 hp). The E 300 d with mild hybrid will make its debut later on, only for Europe.
