GM cuts Facebook ad spending, but Ford steps on the gas

On the eve of Facebook's wildly anticipated initial public stock offering, General Motors said May 15 that it will stop buying advertisements on Facebook--about $10 million a year--but "remains committed" to the social network as part of "an aggressive content strategy with all our products and brands." In other words, GM will not pay Facebook for ads but will continue to maintain content, for which Facebook doesn't collect revenue. News of the decision was reported in The Wall Street Journal. But GM's position is far from universal.

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.
