BMW Four Cylinder Diesels Coming
“You’re going to see it of course in the 3 Series,” BMW’s Tom Baloga tells Inside Line, “and the 5 Series is a good possibility. If the performance [of such an engine] is sufficient in the X3, U.S. customers would likely accept it in the X5 as well.” The “it” he’s referring to is BMW’s two liter turbodiesel engine, which BMW hopes will soon make up 10 to 20 percent of its engine mix in the US. And the Bavarians aren’t bringing the diesel four over for mere miserly mileage alone. “We would be focusing to make sure we get the performance that people expect without squeezing every last mile per gallon out of it,” Baloga says. “I don’t think we would ever consciously look at [the VW Jetta TDI’s] numbers and say ‘we have to beat that.'”
Inside Line claims that the US-bound oil burner is the same one found in BMW’s European 320d, which would make it 177 hp strong. However, BMW also makes a 143 hp version of its two liter diesel as well as a 204 hp version, the latter being the first production oil burner to achieve over 100 hp per liter. However that engine is only available in the 1 Series (123d), making it unlikely to come to America. The 320d burns 4.9 liters of diesel every 100 km, giving it an approximate rating of 48 MPG. It’s important to note though, that European cycles tend to rate higher than EPA, meaning a 320d should arrive somewhere closer to 40 mpg when it arrives in the US. A particle filter is more likely to be used for exhaust cleaning than the urea-injection system used on US-market Audi and Mercedes diesels, although a final decision has not yet been made.
