Filed under: Detroit Auto Show , Hybrid , Sedan , Mercedes-Benz , Luxury In between debuting the Smart for-us and SL on the floor of the Detroit Auto Show today, Mercedes-Benz thought it right to bring out two brown cars that are actually green: diesel and gasoline flavors of the E-Class hybrid. In fact, the E300 diesel hybrid is so efficient that Mercedes calls it the “world’s most economical luxury-class model.” Unsurprisingly, the diesel will launch in Europe while the gas-powered E400 hybrid will arrive first in America and will later come to Japan, China and other countries. Pricing for the E-Class hybrids has not yet been announced, but Mercedes says the “extra cost involved here is only moderate.” As we learned during the slow-burning teaser month of December, the diesel-fueled BlueTec hybrid is expected to get 56 miles per gallon (on the European scale, so around 45 mpg in the U.S.) and the gas-electric E400 Hybrid will get 27 mpg (U.S.). The numbers for the E300 are based on the sedan (saloon) versions; it will also be available in estate (station wagon) form.
