Today Mercedes-Benz announces its European range of engines for the 2010 E-Class Coupe. U.S. offerings likely won't include four-cylinders or diesels (unless diesel popularity undergoes a sea change or fuel prices double). But significant changes to even the uplevel V-6 signals the greater power and efficiency that will make it to U.S. E-Class Coupes.

Probably the biggest news is the fitment of direct injection to Mercedes' 3.5-liter V-6. The current design uses traditional port fuel-injection, a technology that's quickly being abandoned by many luxury automakers (BMW, Audi, Cadillac) for the higher compression, higher efficiency, and greater power afforded by direct injection. This engine comes in the European E 350 CGI (Common rail Gasoline Injection) and is, they claim, "the world's first petrol engine with spray-guided direct injection." The new V-6 yields 292 hp, 269 lb-ft, and fuel efficiency of around 28 mpg converted to U.S. figures (8.5 liters/100 km European). Another notable - and efficient - achievement of the 2010 E-Class Coupe is a drag coefficient in some models of 0.24, a figure Mercedes claims is a "world-best cd figure for any series-production car."
Other engines in the European E-Class Coupe powertrain lineup are a new 204-hp/369 lb-ft 2.2-liter four-cylinder twin-turbo diesel (E 250 CDI BlueEFFICIENCY), 231-hp V-6 twin-turbo diesel (350 CDI BlueEFFICIENCY), 204-hp 1.8-liter direct-injected gasoline four-cylinder (E 250 CGI BlueEFFICIENCY), and the familiar 388 hp 5.5-liter V-8 (E 500 Coupe).
U.S. E-Class coupes have historically been offered only with gasoline six and eight-cylinder engines, but we're hoping that the burgeoning popularity of fuel-efficient luxury will bring us some of the frugal gasoline or diesel European engines. The 369 lb-ft torque and 46 mpg offered by the 2.2-liter turbodiesel sounds like a winning combination.
