Daimler AG’s Mercedes-Benz unit is launching plug-in hybrid versions of its entry-level A- and B-Class cars.
The 2020 models team a 1.3-liter 4-cylinder engine with an electric motor to generate a combined 218 hp and 332 lb-ft of torque. The plug-in small cars take 6.6 seconds to accelerate from zero to 62 mph, which is 0.4 seconds slower than their conventionally powered counterparts.
The hybrid powertrains are mated with an 8-speed dual-clutch transmission that drives the front wheels. The engine is started by the electric motor—a first for a Mercedes hybrid.
Supplied by Daimler’s Accumotive GmbH subsidiary, the cars’ 15.6-kWh lithium-ion battery provide a 40-mile all-electric range on the European driving cycle. Mercedes says the battery can be fully recharged in less than two hours via a standard outlet and to 80% capacity in 25 minutes via a DC fast charger.
The third-generation hybrid system taps into the navigation system to maximize the use of electric power during a trip. To help make room for the electric components without sacrificing interior or trunk space, Mercedes shortened the exhaust system and integrated the fuel tank into the axle installation space.
The A 250 e plug-in will be available as either a hatchback or sedan; the B 250 e is an MPV. Sales of the vehicles kick off this autumn in Europe. Mercedes hasn’t said whether it will offer the plug-in hybrid small cars in the U.S.
