2017 Mercedes S 500 e Coming with Longer Range Battery

Daimler is adding to its electrified vehicles campaign with a longer-range 2017 Mercedes S 500 e.

The new Mercedes S 500 e (badged as the S550e in the U.S.) plug-in hybrid will be getting a 13.3 kWh battery. That’s up from its current 8.7 kWh battery, and will offer a 53-percent increase in its battery-powered miles. It will also be getting an exterior facelift.

Mercedes says that the S 500 e will be its first PHEV to exceed a 50 km (31 miles) range rating. That’s based on the European NEDC battery mile standard. That could mean a potential increase of perhaps 30 km (19 miles) by U.S. Environmental Protection Agency standards, but this will remain to be seen. There could be some differential, with the 19-mile estimate based on all-electric range and the Mercedes S 500 e being a plug-in hybrid.

“The next major technological leap will be made in 2017, starting with the facelift of the S 500 e: for the first time, fully electric operating ranges exceeding 50 km will be made possible by a further development of the lithium-ion battery together with a further optimized, intelligent operating strategy,” Mercedes states.

The battery system will come from Deutsche ACCUmotive, a wholly-owned Daimler subsidiary. It will also be supplying, for the first time, accumulators for plug-in hybrids from Mercedes-Benz, the company said. Mercedes expects to see further progress in battery technology to gradually increase battery capacity and operating range.
