Mercedes-Benz has killed off its current batch of plug-in hybrid vehicles ahead of the brand’s next-generation EQ cars. In the meantime, the C-Class, E-Class, S-Class, and GLE-Class will soldier on without a plug-in hybrid variant.

The German luxury brand told Autocar in a report Friday that the plug-in hybrids will be replaced in the months to come. First up will be the S-Class, however. Each plug-in car will boast the brand’s third-generation plug-in hybrid powertrain under the new “EQ” badging. Mercedes will race in Formula E with its EQ name as well.

The powertrains feature extensive updates over the second-generation units. According to the report, the electric motor will contribute 121 horsepower and 325 pound-feet of torque to the car’s final power output. When running on pure electricity, the powertrain can now travel at speeds up to 87 mph versus 81 mph previously. Electric range is estimated to grow from around 21 miles to 31 miles on the European test cycle.

Look for the S-Class to arrive with the new technology first with the S560e model. The range-topping sedan was revealed last year with the third-generation powertrain and features a 13.5-kilowatt-hour battery pack. Adding the power of the gasoline V-6 to the electric motor and the power figure sits around 487 hp.

Following the S-Class will be two E-Class plug-in hybrids. One will pair with a four-cylinder diesel engine and the other a gasoline-powered four-cylinder engine. The report added the first E-Class plug-ins will arrive later this year. Spring of 2019 will see the C-Class plug-in hybrid debut.
