Smaller than the X3, the BMW X1 is a compact five-seat SUV. The base 240-hp, turbocharged four-cylinder, mated to an eight-speed automatic, provides quick acceleration and is available with rear- or all-wheel drive. The 3.0-liter, 300-hp turbocharged six-cylinder gets a six-speed automatic. The X1 feels quite sporty to drive, but ride comfort is on the stiff side and the sharp and communicative steering feels heavy at low speeds. Noise isolation and interior quality are a notch below BMW's high standards, but still decent. Stick to basic models with the Premium and Cold Weather packages. Indulging in the myriad high-end trim options can launch the price into the stratosphere, even used. The 2.0-liter engine is plenty powerful, so you can skip the six-cylinder. Electronic stability control, traction control, antilock brakes, brake assist, dynamic cruise control, and daytime running lights are standard.
