A long history of differing car tastes show Canada is not just another state. Automakers from the U.S. and around the world sell versions of their cars in Canada that you can't buy in (and they go to great lengths to keep you from importing them to) the U.S.
BMW's brawny, turbocharged 2.0-liter four-cylinder engines are available only in the X1, X3, Z4, and 5-series in the U.S, where they make 240 hp and score a decent 34 mpg on the EPA highway test. In Canada, however, you can get a milder version that makes just 181 hp and returns nearly 40 mpg on the highway, in the 320i. The 320i (a designation that harkens back to the original progenitor of the fabled 2002) would cost about $33,800 if sold in the U.S., $600 cheaper than the least-expensive five-seat 3-series in the U.S.—the 328i, which gives you nearly 50 hp more than the 320i. But with gas that costs about $5 (U.S.) per gallon, Canadians seem to be more willing to a pay a premium for mpg over horsepower.
