The company has already announced it has invested $2.8 billion into developing eco-friendly hybrid versions of every model. The Mercedes-Benz S-Class electric is said to be a full electric model though, using no petrol or diesel hybrid assistance.

Mercedes-Benz technical boss, Thomas Weber, hasn't ruled out the potential of an electric model, saying in a recent Autocar report, "At the moment, we are looking at customer demand".

Even without an electric variant, the new S-Class promises to be more fuel efficient across the range, with the introduction of the first ever four-cylinder S-Class on the list. Badged the S250 CDI, it will feature a 2.2-litre turbo-diesel engine producing 150kW of power and 500Nm of torque.

Other revisions to the new model include V6 and V8 MoVe petrol engines as well as a plug-in hybrid version. The new model is expected to debut sometime in 2013.
