Spied: Mercedes CL-Class (CL400?) hybrid

Spy photographers have spotted what appears to be the first prototype for a Mercedes-Benz CL-Class hybrid testing in Europe. On the outside, the car looks very much like a regular CL, except for the unusual components protruding from the hood on this test car.



According to our sources, BMW hybrid prototypes have similar instrumentation coming out of the hood, albeit cloaked by fake "powerdomes."

Not much is known at this time of the CL hybrid, but the big Benz coupe will probably be powered by the same unit as the hybrid S400 sedan.

If making small, efficient cars more efficient saves a little bit of gas and the associated pollution, then surely making big cars more efficient is even more effective. This logic seems to be resulting in more big hybrids out there. Lexus has the first luxury V8 hybrid with its LS 460h and also offers hybrid versions of its RX SUV and GS sports sedan.

A recent report provided a timeframe for the arrival of a hybrid 7-series from BMW, and many other automakers are also gaining interest in the segment. From the high-performance Fisker Karma to the hulking Chevrolet Tahoe Hybrid, it's clear gas-electric powertrains aren't limited to economy cars.
