Mercedes-Benz E-Class Gains Revised PHEV Powertrain, Headed For U.S.

It’s the first electrified E-Class to be sold in the States.

Mercedes-Benz has thoroughly refreshed its midsize E-Class model, and while its exterior and interior changes are noteworthy, we’re interested in the revised E350e motivated by the brand’s third-generation plug-in hybrid system.

It pairs a 2.0-liter turbocharged four-cylinder with an electric motor for a total of 315 horsepower combined at 5,500 rpm (the previous iteration of the PHEV powertrain had 275 horsepower combined).

Peak torque for the system comes in at 516 pound-feet (700 Nm), which is delivered flat between 1,300 and 4,000 rpm. Mercedes doesn’t quote its performance figures yet, but it should be able to do the benchmark sprint in under six seconds, at least in dry conditions because it’s only available with rear-wheel drive; top speed is limited to 130 mph (210 km/h).

The 90 kW (120 horsepower) electric motor provides a lot of the system’s peak twist – its maximum torque is 325 pound-feet (440 Nm). The motor provides the exact same torque as in the outgoing E350e model (that featured Mercedes’ second-gen PHEV powertrain), but more power and this helps boost the overall power figure.

The battery it draws from is most likely a 13.5 kWh pack (maximum charge rate is 7.4 kW) that in the case of the mechanically similar GLC350e provides a claimed all-electric range of between 26 miles (43 km) according to the WLTP test cycle. This number will drop when the vehicle is tested by the EPA, which it will since this E350e will be the first electrified E-Class to be sold in the United States.
