Emphasizing sport over utility, the X4 is a coupelike version of the previous-generation X3. It's agile, rides tautly, and has a beautifully trimmed cabin. Seating is a bit lower than in the X3, which instills a more sporty experience. Cargo and rear-seat space under the sloping roofline are considerably smaller than in the X3, making the X4 a less practical SUV. Engine choices are a 240-hp, 2.0-liter turbo four-cylinder and a particularly smooth and powerful 355-hp, 3.0-liter turbo six-cylinder on the high-performance M40i version. An eight-speed automatic transmission and all-wheel drive are standard. In our brief time with the X4, we found that the optional 19-inch tires make the ride a bit too jiggly. A second generation X4 based on the redesigned X3 goes on sale this summer.
