Considerably less fuel consumption despite a much higher output was the development objective for the new Mercedes-Benz V-engine generation, which will initially be used as an 8-cylinder in the CL-Class, and later in the S-Class from autumn 2010. Mercedes-Benz developed the new six and eight-cylinder units because optimised internal combustion engines continue to have specific advantages over other drive systems with respect to operating range and refuelling time and costs, while offering the greatest short-term potential to achieve significant fuel savings in day-to-day operation. The V8 is in a new league of its own On the basis of its predecessor, the new V8 has undergone concerted further development. For example, it has a 15-percent smaller displacement (4663 cc rather than 5461 cc) but generates 320 kW (435 hp) and therefore around 12 percent more output than the preceding unit (285 kW/388 hp). Whereas the current CL ...
