2005 BMW X3

The 2005 BMW X3 marked the introduction of a compact luxury crossover SUV from BMW. It offered a blend of BMW’s sporty driving dynamics with the practicality of an SUV. The 2005 X3 was available with two inline-six engine options: a 2.5-liter engine producing 184 horsepower and 175 lb-ft of torque and a 3.0-liter engine producing 225 horsepower and 214 lb-ft of torque. Both engines were typically paired with either a 5-speed manual transmission or a 5-speed automatic transmission. Owners often praised the X3 for its responsive handling, all-wheel-drive system, and premium interior. Common criticisms included a somewhat stiff ride, limited rear-seat space, and higher maintenance costs associated with European vehicles.
