Mercedes-Benz is open to the idea of selling four-cylinder diesel engines in several different American-market cars, according to Wards Auto. The automaker has already confirmed that it will sell a four-cylinder turbodiesel engine in the 2013 GLK-Class crossover, and that engine could migrate to other vehicles.
The 2013 GLK-Class (pictured) was introduced at the New York auto show, and starting next year, Mercedes will sell the GLK250 Bluetec model with a turbocharged 2.1-liter inline-four diesel making 190 hp and 369 lb-ft of torque. It is said to be "extremely frugal" and return higher fuel-economy figures than gasoline versions of the GLK.
That 2.1-liter diesel engine seems likely to spread to other cars in the Mercedes range. Gunter Fischer, project manager for the Mercedes SL-Class, told Wards that four-cylinder diesels would provide enough performance and economy to be used in the American-market C-Class, SLK-Class roadster, and E-Class sedan. The German automaker reportedly believes that four-cylinder diesel engines will be a good way for Mercedes to improve fuel economy in American models.
"We brought a four-cylinder gasoline engine to the U.S. Why shouldn't we do that with a four-cylinder diesel?" Fischer told Wards.
Mercedes already sells other diesel models in the U.S. market: the ML350 BlueTec, GL350 BlueTec, S350 BlueTec, R350 BlueTec, and E350 BlueTec use a 3.0-liter turbodiesel V-6. The company also has launched a gasoline four-cylinder -- a turbocharged 1.8-liter inline-four -- in the C250 sedan and coupe, and SLK250 roadster.
