While the BMW 3-Series diesel never really took off in the North American market, diesel powered Bimmers make up about 50 percent of European 3-Series sales, and the brand reports similar numbers for the X5 in North America.
BMW USA execs admit that there's still an issue of convincing customers regarding how well modern diesels operate, but also said that oil-burners may be crucial to meeting future CAFE standards. While this left the door open for a diesel 3-Series, BMW USA has ruled out a 3-series wagon, stating that volumes would be so minimal that it would be difficult to justify selling it Stateside.
Ian Robertson, BMW's head of sales and marketing, also derided the auto industry's obsession with cylinder count and displacement, stating that BMW's forthcoming nomenclature would reflect performance rather than the actual displacement the new 328i, for example, would actually use a 2.0L turbocharged 4-cylinder rather than a 2.8L 6-cylinder engine.
