The next X3 will be about four inches longer, a half-inch narrower, and a fraction of an inch taller. The extra length will help improve interior room, but the Sport Activity Vehicle is said to be tuned for increased sporting performance. The features list will include hand-me-downs from the 7 Series such as Night Vision and Heads Up Display, and -- in Europe at least -- six engines will be offered: two gasoline and four diesel. We in the U.S. will probably still make do with the either the naturally aspirated or turbocharged 3.0-liter gas engines and possibly a turbo'd four.
