Already an eye-popping package of performance, luxury and technology, the 2015 Mercedes-Benz S-Class is about to raise ye olde bar once again: This time with a sophisticated plug-in hybrid powertrain that Mercedes claims can return the equivalent of 84 mpg in combined travel (in European testing), while also providing 20 miles of all-electric, zero-emissions driving.
Other preliminary specs for the 2015 Mercedes-Benz S-Class plug-in hybrid show it starts with a twin-turbo 3.0-liter V6 engine making 329 hp and 354 lb.-ft. of torque, then complements that setup with an 8.8 kWh lithium-ion battery and 85 kW electric motor. Working together, the system serves up a total of 436 hp and 479 lb.-ft. of torque, which is enough to propel the plug-in 2015 Mercedes-Benz S-Class from 0-62 mph in 5.2 seconds, with an electronically limited top speed of 130 mph.
M-B also provided some information about charging times for the 2015 Mercedes-Benz S-Class plug-in hybrid, noting that a battery at 20 percent of capacity can be fully recharged in two to four hours, depending on the source of electricity. Speaking of which, future plans for the 2015 Mercedes-Benz S-Class plug-in do include wireless inductive charging, although exact timing of that feature remains up in the air at this time.
Added Prof. Dr. Thomas Weber, member of the Daimler Board of Management responsible for Group Research and Mercedes-Benz cars Development: "The S550 PLUG-IN HYBRID is the first luxury sedan with the performance of a V8 and the fuel consumption of a compact model. The greatest challenge in this is to translate efficiency into superior performance. In this respect there is a highly interesting parallel with our successful Formula 1 racing car, which likewise has a turbocharged V6 engine and a high-tech hybrid drive."
