Mercedes-Benz is already working at the second generation CLS that will make its world debut during a major car show in late 2010 with sales following in early 2011. Big news is, that next to the standard engine, the future CLS will also be offered as a hybrid. It will get the same powertrain as the forthcoming S400 Hybrid that will be launched at the end of 2009, which means that the CLS Hybrid will make use of lithium-ion batteries that not only weigh less but also offer more power than the nickel hydride units used in today�s hybrids. Design will follow the basic shape of the current generation model adorned with styling elements from the German automaker�s newest cars.
