The S 550 e is a plug-in hybrid version of the long wheelbase S-Class sedan, with a 3.0-litre V6 twin-turbo engine rated at 245 kW; 328 hp (333 PS) and 480 N⋅m (354 lb⋅ft) and an electric motor rated at 80 kW; 108 hp (109 PS) and 340 N⋅m (251 lb⋅ft), and with an externally rechargeable 8.7kWh battery pack. It features 4 hybrid operating modes (HYBRID, E‑MODE, E-SAVE, and CHARGE), second-generation regenerative braking system, haptic accelerator pedal, pre-entry climate control of the interior, and Intelligent HYBRID with (dis)charging management based on COMAND Online navigation data. The all electric range is about 30 km (19 mi) under the New European Driving Cycle. Under the U.S. Environmental Protection Agency (EPA) tests, the S 500 e has an all-electric range of 14 mi (23 km), with some gasoline consumption (0.1 gal/100 mi). So, the actual all-electric range is rated between 0 and 12 mi (0 and 19 km). The EPA, under its five-cycle tests, rated the 2015 S 500 e energy consumption in all-electric mode at 59 kWh per 100 miles, which translates into a combined city/highway fuel economy of 58 miles per gallon gasoline equivalent (MPG-e) (4.1 L/100 km; 70 mpg−imp gasoline equivalent). When powered only by the gasoline engine, EPA's official combined city/highway fuel economy is 26 mpg‑US (9.0 L/100 km; 31 mpg‑imp). The production vehicle was unveiled in Toronto in 2013, followed by the 2013 Frankfurt Motor Show. Deliveries began in September 2014 in Europe, starting at a price of €108,945 (~US$146,000). The U.S. launch was slated for early 2015. A total of 17 units were registered in Germany as of September 2014. According to JATO Dynamics, a total of 38 units were registered in Europe through September 2014.
