BusinessWeek have published a "test driven" review of the new Mercedes GLK-Class SUV. 'The GLK, which goes on sale in Europe in October and in the U.S. early in 2009, is Mercedes' most important new car of the year, and it's good—if you ignore the fact that soaring fuel prices are causing SUV sales to plunge. At least the GLK is a so-called compact SUV. "Compact" in this case presumably means "compared with a Hummer." But the GLK does get decent gas mileage for a 2-ton vehicle. The 4-cylinder diesel version is rated at 34 miles per gallon (or, in European terms, 6.9 liters per 100 kilometers). The 6-cylinder gasoline version that will be sold in the U.S. gets just 22 mpg, however. (Mercedes hasn't yet announced a U.S. price for the GLK, but the same car costs more than $60,000 in Germany.)'
