Emphasizing sport over utility, the X4 is a coupelike variant of the X3.
It's agile, rides tautly, and has a beautifully trimmed cabin.
Front and rear seats are lowered to keep passengers' heads from hitting the low roof, and the cargo space shrinks considerably under the sloping rear hatch, making it a less practical SUV.
Engine choices are a 240-hp, 2.0-liter turbo four-cylinder and a 300-hp, 3.0-liter turbo six-cylinder that is particularly smooth and powerful.
Both engines are mated to an eight-speed automatic transmission, and all-wheel drive is standard.
Optional 19-inch tires make the ride a bit too jiggly.
