Mercedes-Benz continues its electrification
offensive with two new plug-in hybrid models based on the E-Class. They’re called the E300e and
E300de and they’re using gasoline and diesel engines, respectively. Both target
the same type of client: frequent drivers who want long-distance comfort and
zero emissions in inner-city areas. Replacing the previous E350e, the E300e
uses a 211 PS 2.0-liter turbocharged four-pt, a 90kW (122 PS)
electric motor, and a 13.5kWh battery.
The result is a system output of 320 PS and
combined torque of 700 Nm. Consequently, the E300e is quicker than
its predecessor. 0-100 km/h (takes 5.7 seconds and the top speed is
limited at 250 km/h.
More importantly, however, the all-electric driving
range increases to 50 km compared to the E350e’s 33 km.
Finally, the claimed average fuel consumption (NEDC) is 2 liters/100 km (117.6
mpg US), with corresponding CO2 emissions of 45 g/km.
As for the E300de, it features a 194 PS 2.0-liter turbo diesel and the same electric motor and battery from its
gasoline-powered counterpart. System output and torque are similar: 306 PS and 700 Nm, respectively. The 0-100 km/h sprint
takes 5.9 seconds and the driving range in EV mode is as high as 54 km.
Combined fuel economy is rated at 1.6 l/100 km (147
mpg US), with CO2 emissions of 44-41 g/km. Unlike the E300e which is only
offered as a sedan, the E300de can be had both in sedan and wagon body styles. In both hybrid models, the
electric motor is located in the hybrid traction head of the 9G-Tronic
nine-speed automatic transmission and delivers 440 Nm from a
standing start.
The battery can be charged from 10 to 100 percent
SoC (State of Charge) in about 1.5 hours at a Wallbox, thanks to a 7.4kW
water-cooled onboard charger. Using a conventional domestic power socket, it
takes approximately 5 hours to replenish the battery.
