2007 Mercedes CLS-Class (CLS 500, CLS 350 CGI)

You've already seen the 2007 Mercedes CLS 63 AMG, so now have a look at the 2007 CLS500 and CLS350 CGI. The CLS 350 is powered by the world's first gas engine featuring piezoelectric direct injection and spray-guided combustion, offering 292 horsepower in a six-cylinder package. Meanwhile, the CLS 500 will be equipped with the new V8 engine from the S-Class, whose output of 388 hp is about 26 percent higher than that of the previous eight-cylinder engine. (It's not clear why the S-Class model is called S550, yet the new four-door coupe is not called CLS550.) More info and photos after the jump...
