By the way, from reading the April 2005 issue of Motor Trend, I have a hunch that the 3.0-liter "low tech" I-6 that will be on the E90 3-Series for the North American market could be built similar to what BMW did with the 2.7-liter I-6 eta engine from the 1980's--higher than normal compression ratio and special engine computer programming for more emphasis on fuel economy than performance. My educated guess on fuel economy per EPA rating: 24 mpg city, 34 mpg highway, similar to what Honda did with the K24 2.4-liter I-4 engine used on the Honda Accord.
