Mercedes has started accepting orders on the new 2019 E350 Coupe and Cabriolet models, which are powered by a 48-volt mild-hybrid powertrain.

The new E350 combines a 2.0-liter four-cylinder petrol engine with the brand’s EQ Boost hybrid system comprised of a belt-driven starter/alternator and a 48-volt electrical system. The EQ Boost adds 14hp to the overall output, which is set at 299hp and 295lb-ft (400Nm) of torque.

The mild hybrid powertrain is paired to the company’s 9G-Tronic Plus nine-speed automatic transmission. 0-62mph (100km/h) comes in a claimed 5.9 seconds for the Coupe and 6.1 seconds for the Cabriolet. Another interesting fact is that the specific powertrain is exclusive to this E-Class version, at least in the UK.

Since this is a mild hybrid, we need to talk about fuel economy. Mercedes claims 40.9 mpg UK (6.9 lt/100 km) combined and CO2 emissions of 158gr/km (Cabriolet: 39.8 mpg UK, 163gr/km of CO2).

Standard equipment is quite generous, and includes features like the big 12.3-inch digital displays for the dashboard, blind spot assist, illuminated door sills, 19-inch alloy wheels, electrically adjustable and heated front seats, privacy glass, ambient lighting, open-pore ash wood trim and black Artico leather upholstery.

For an additional £3,450 (£4,395 for the Coupé), you can opt for the Premium Plus package that adds a Burmester surround sound system, keyless-go and a panoramic sunroof (the latter in the Coupe only for obvious reasons).

Pricing for the new E350 Coupe starts from £44,750 OTR, while its Cabriolet sibling is priced from £49,246. Mercedes will begin delivering the first customers cars in the UK in spring 2019.
