Cadillac S-class fighter confirmed

General Motors CEO Dan Akerson recently revealed to USA Today that a new Cadillac S-class and 7-series fighter is in the works. He suggested it would be released in about two years.

Mercedes-Benz CL gets a facelift for 2011

Three years after its introduction, Mercedes-Benz has given the CL a mid-cycle facelift, providing the big two-door with lightly altered bumpers--those up front with new LED daytime running lamps, reshaped headlamps, a more contoured hood, larger exterior mirrors with integrated indicators and revised tail-lamp lenses, among other detailed visual changes. More significant than the styling tweaks, however, are the changes underneath the hood, with the arrival of a new twin-turbocharged 4.6-liter V8 direct-injection gasoline engine--the first of Mercedes-Benz's advanced MoVe powerplants that aim to bring efficiency gains to its lineup. With 429 hp and 516 lb-ft of torque, the new engine delivers 47 hp and 125 lb-ft more than the naturally aspirated 5.5-liter V8 it replaces in the four-year-old CL500--enough to lower the luxury coupe's 0-to-62-mph time by 0.5 second to 4.9 seconds.
