Putting a bank of batteries into the Mercedes-Benz S-Class is not a new idea – the S500 Vision Plug-in Hybrid concept was unveiled in Frankfurt in 2009, after all – but actually adding a cord to a production version sure is – at least in public. We don't know how long Daimler has been considering making a plug-in hybrid version of the S-Class, but Australian media outlets are reporting that such a vehicle was accidentally disclosed during a recent presentation in Germany.

Motoring and Car Advice both say they saw a graphic of a "W222 S-Class PHEV" that showed a dash indicator of remaining battery range. There was also a "graphic drivetrain schematic featuring an electric motor sitting behind a conventional engine and a battery pack positioned in the boot," writes Car Advice. Despite this, there is, of course, no guarantee that any such vehicle will ever make it to market. And, as we asked years ago when we reviewed the 2010 Mercedes-Benz S400 Hybrid, who is it for?

A M-B spokesman in Australia, Jerry Stamoulis, told Motoring that, "The reality is that there is a lot of spec still to be confirmed; the car is so far away for us. It's (the mainstream S-Class is due here) in December – and if there were plug-in hybrid variants there's no guarantee that they're actually available from launch anywhere in the world." It'll take a while to see if showing off the image was a mistake or a leak to gauge interest, but we admit we like this tease.

      No congestion charge, access to carpool lanes, etc. may be enough to justify this.. Though it would be nice to see MB electrify with an efficient backup genset since electric powertrains are superior in terms of efficiency, reliability and simplicity.

        Nailed it. Your luxury legacy sedan loses its elegance when it relegates you to the slow lanes leaf, model S drivers pass you by.

      And, as we asked years ago when we reviewed the 2010 Mercedes-Benz S400 Hybrid, who is it for? It's for the government regulators of the world. S class owners in Europe will go for the diesel, in the Middle East and USA a V8, and Asia a V12 LWB version.

        Most hybrid luxury power-trains provide better acceleration and better fuel efficiency than their conventional counterparts. Adding electric motors is the only way that Mercedes can hope to offer a sedan than can beat the Model S 0-60 time of 3.9 seconds. http://www.autoblog.com/2012/08/27/motor-trend-tests-tesla-model-s-finds-0-60-in-3-9-sec-an/

          Mercedes does not have to beat a model S in 0-60 times. They just have to maintain their sales and profit per car. There are many cars faster than a V8 S class, some even cost half as much. Chrysler 300 SRT8 for example.

      Daimler has been watching with alarm at the increasing competition from Toyota's Lexus 600 series hybrids to the Mercedes-Benz S-Class. Lexus have made serious inroads into a market that was traditionally owned by Mercedes. The Lexus provides better value, and more modern technology, while equalling build quality.

        Equalling? Lexus has been routinely besting Mercedes in build quality and reliability.

      Yeah, I almost feel guilty blowing past tons of BMWs, Audis, Porsches, Volvos, Range Rovers, Cadillacs, Mercedes, etc. in my low-grade EV as they sit there stuck in traffic. But hey, they could do the same thing and oil usage would drop heavily. And better yet, many of them would see the light on PV solar systems and buy one. Heck, they are cheaper than the EVs and will provide electricity to power EVs for some 30+ years.

      Considering the huge letters reading PLUG-IN HYBRID on the side (in 90,000 point letters), I assume this isn't meant to be a secret.

      alot of these plug in hybrid are coming, because there is no other way to meet cafe standard, except somr form of electrification.
