Chevy Malibu Eco hybrid is a tough sell

Most prospective Chevrolet Malibu buyers at Castle Chevrolet in suburban Chicago quickly decide that they don't want to pay nearly $3,000 more for the Eco mild-hybrid version. "For most people, it's hard to justify the extra money based on the extra fuel economy" of a combined 3 mpg more than the base model, says Jeff Tuckman, the dealership's inventory manager. "You've got the base LS model sitting next to it that's just as nice and luxurious." It's a problem flagged by many Chevy dealers.

Citroen C5 Airscape concept

Following the C-Airlounge of 2003, the C-Airdream of 2005 and the C-Airplay of 2006, is the C5 Airscape. Due to make its international debut at the Frankfurt Motor Show next month, this new Citroen concept acts as a spoiler for the forthcoming upper-medium C5 replacement dues soon. Unlike the forthcoming production car, the concept is a four seat coupe cabriolet which is aiming to show a new level of premium quality for the brand.

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.
