Mercedes is introducing the new generation of its M-class series. The automaker has traditionally been behind the curve when it comes to eco-friendly technology, but they want to change that now. The new M-class is expected to consume 25% less fuel than its predecessor and it will meet European emissions standards too. All the gas and diesel engines have been redesigned with seven-speed gearboxes - and they, too, consume less fuel, thanks to the start-stop function. The new M-class resembles both the CL luxury convertible and the E-Class, but all in all it's kept the traditional M-Class look. Drive It! takes the new car out for a spin.
