It was roughly two months ago when we first heard of an upcoming Mercedes-Benz S-Class plug-in hybrid via some leaked slides at an M-B presentation.  Now, Mercedes-Benz has officially confirmed that its flagship S-Class will indeed get a plug-in hybrid added to the lineup in 2014.

Mercedes-Benz’s next generation flagship S-Class was introduced at an elaborate event in Germany, but the S500 Plug-In Hybrid wasn't present.  Instead, M-B wheeled out several plug-less variants of the 2014 S-Class.  That's because the plug-in S-Class won't be available at initial launch.

Mercedes says the plug-in S-Class, officially called the S 500 Plug-In HYBRID, will arrive in early 2014.

No details were released on this plug-in Mercedes aside from a tossed out fuel economy figure of this: "first S-Class with a fuel consumption lower than 4l/100 km (59 mpg US)."

We believe the 2014 S-Class plug-in will be able to cover approximately 20 miles in electric-only mode and that it'll likely feature a V6 engine.  Beyond that, it's all guesses.

We'll have more details on the 2014 S 500 Plug-In HYBRID closer to its launch, which is tentatively set for sometime next year.
