Mercedes-Benz Creates A Plug-In HYBRID Luxury Concept Car

STUTTGART, GERMANY - Mercedes-Benz unveiled at the end of last year a close to production technology concept version of their S-Class luxury sedan using a very high efficiency plug-in hybrid powertrain. It is called the Vision S 500 Plug-In HYBRID, and this Mercedes-Benz S-Class is a hybrid car that can be plugged into a home power outlet to charge the S 500 Hybrid's 10 kWh onboard lithium-ion battery pack.

The S 500 Plug-In HYBRID has a 3.5 L 24-valve gasoline (petrol) engine combined in a hybrid electric arrangement with a 44 kW/60 hp electric motor. Mercedes-Benz says that the S 500 Plug-In HYBRID can drive for 30 km (18.8 miles) using its battery power alone and when using a high amperage charger, the lithium-ion battery pack can be fully charged in under 60 minutes. If a standard home outlet is used to charge the Mercedes-Benz Plug-In S-Class it will take about 4.5 hours to charge the car.

The most obvious benefit from Mercedes-Benz's use of a plug-in hybrid powertrain in the S 500 Plug-In is that it gives this large S-Class the fuel efficiency of a micro-compact, achieving an incredible combined 3.2 L/100 kms or 73.5 US MPG (88.3 Imp MPG). This is also achieved with a very low NEDC (New European Driving Cycle) CO2 output of just 74 grams per kilometre. The S 500 Plug-In HYBRID can also accelerate incredibly fast with a zero to 62.2 mph time of just 5.5 seconds, and a top speed of 250 km/h (155 mph).

By Using the electric motor to help the S 500 Plug-IN HYBRID accelerate, Mercedes-Benz engineers have given the car a combined hybrid torque of 250 Nm, giving the car fast acceleration times coupled with a high efficiency combustion process for the gasoline (petrol) engine. Mercedes-Benz mounts the S 500 Plug-In HYBRID's lithium-ion battery pack behind the rear passenger seats in the trunk (boot) area.

The S 500 Plug-In HYBRID is part of Mercedes-Benz's business strategy to be a leader in delivering high-efficiency luxury motoring with low CO2 emissions and even zero emissions in the case of their upcoming electric cars. They say that their engineers are working very hard to make the S 500 Plug-In HYBRID a production reality for not-so-distant future.
