The 2014 Mercedes Benz S Class recently entered production in the Sindelfingen plant in Germany. The all new S Class is currently on sale with a single diesel engine and a couple of petrol engines.
Mercedes is planning to launch the Plug-in Hybrid version of the new S Class at the 2013 Frankfurt Motor Show in September. In fact, this has been confirmed as the show's premiere list displays the Mercedes S500 Plug in Hybrid as one of the world premieres.
The car that you see here is the S500 Plug in Hybrid, which was showcased at the media launch of the S Class in Toronto, Canada.
The S500 Plug-in will combine a V6 petrol engine along with an electric motor and a battery pack. The battery will be mounted in the boot of the car. While the power and performance figures are still unknown, it is believed that Mercedes would be targeting a sub 70g/km CO2 emission making this the cleanest S Class ever made.
To put things in perspective, the Porsche Panamera Hybrid does 71g/km while two of the three Toyota Prius do 89g/km and 96g/km. If Mercedes achieves this figure, the S Class would be greener and cleaner than a Toyota Prius!!
The S500 Plug in would achieve 90mpg (UK) or 31.861km/l. To give you a comparison, the 2014 Honda Jazz Hybrid is rumored to achieve 36km/l.
