Mercedes-Benz F125 concept

Mercedes today revealed the F125 concept at the Frankfurt motor show. Claimed to represent ‘a radical reinterpretation of a sports sedan', the new car is also said to preview the next generation S-Class. Created in close collaboration between the technical research and development departments, as well as the Advanced Design Studios in Sindelfingen and Carlsbad, CA, Mercedes says the exterior design of the F125 is a further development of the company's current design strategy, with organic use of body surfaces, a cab-forward stance and short overhangs.

Mercedes Vision S500 Plug In Hybrid (2009)

By Ben Pulman First Official Pictures 11 September 2009 09:55 This is Mercedes’ latest Vision concept car, the S500 Plug-in Hybrid, and it will be unveiled at the Frankfurt motor show next week alongside an electric version of the company's new SLS supercar. Based on the current-gen but pre-facelift S-class the S500 Plug-in Hybrid achieves over 88mpg but only emits 74g/km, and the company claims the car demonstrates 'the future of Mercedes' modular set of hybrid systems.' All next-gen S-classes are expected to get stop/start technology as standard, while full hybrid and plug-in hybrids will also be offered. Merc is claiming that its S500 Plug-in Hybrid is the world’s first 'three-litre' limo, offering 88.3mpg (or 3.2l/100km), figures that shame the Lexus LS600h (30.4mpg), BMW’s 7 ActiveHybrid (29.1) and even the company’s own S400 Hybrid (35.8).
