Mercedes-Benz S550e to get wireless charging option

Recent reports suggest the revised plug-in hybrid will also get longer all-electric range.

Mercedes-Benz' S550e may be the first plug-in hybrid to be offered with a wireless charging system directly from the factory.

The revised hybrid sedan will launch with integrated inductive coils as an optional upgrade, according to Green Car Reports.

The system is expected to deliver up to 3.6 kilowatts of electricity, with an efficiency rating of more than 90 percent. For reference, the Nissan Leaf's 24-kWh battery takes eight hours to fill via a 3.6 kW charger.

The mid-cycle update is also due for a larger battery pack, jumping from 8.7 kWh to 13.5 kWh. Reports suggest the 55-percent capacity increase could push electric range to 30 miles or higher.

The higher-capacity battery promises to arrive without any weight penalty. It is also expected to take advantage of a more powerful electric motor, potentially bringing a modest performance boost.

The refreshed S550e is expected to land in US showrooms next year for the 2018 model year.
