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.

Volkswagen Passat TDI covers 1,626 miles on a single tank of fuel

John and Helen Taylor recently drove a 2012 Volkswagen Passat TDI carefully enough to return an unbelievable 84.1 mpg on trip from Houston, Texas, to Sterling, Va. That's 1,626.1 miles on one tank of low-sulfur diesel. That's almost 100 miles better than the old world record.

2014 Range Rover adds supercharged V6

In addition to a complete inside-and-out redesign, the big story for the new-for-2013 Range Rover was the weight savings -- about 700 pounds worth thanks to an all-aluminum unibody structure. On Wednesday, we caught wind of the 2014 model. Word on the street is Jaguar-Land Rover's 3.0-liter supercharged V6 will replace the normally aspirated V8 for next year.
