The new BMW X3, which features the latest (third) generation of BMW's xDrive all-wheel-drive technology, gets an incredible 50.
4 mpg when equipped with the 2.0-liter 4-cylinder turbo engine. The only problem is that the diesel isn't (yet) slated to be available in the U.S.
Last May, BMW promised two new diesels within 12 months. One is likely to be the 535d. The other is a big question mark but an X3 that gets 50+ mpg would be a key differentiator since the current diesel SUVs that are sold in the U.S. barely get half that.
