BMW and Mercedes-Benz Considering 4-Cylinders for the US

We’ve been hearing rumors for a while that BMW and Mercedes-Benz are considering bringing back 4-cylinders to the US to cut their brand’s overall fuel economy.

BMW is currently working on a turbocharged, direct-injected four-cylinder that will likely be used in the 1 and 3 Series sometime around 2012. The new four-cylinder is expected to have the similar horsepower numbers as the current in-line sixes, but with better gas mileage and lower emissions. The engine is also slated for the X1 and new X3. BMW is waiting to decide on the engine for the U.S. until Washington releases what the new fuel economy standards will be.

Mercedes-Benz hasn’t released any details on what the possible 4-cylinder engines could be, although a 2.2-liter four-cylinder turbo-diesel was shown in the E250 Bluetech concept. A four-cylinder will most likely be offered in the C-Class and GLK within the next few years.
