The BMW X3 is a compact crossover SUV marketed by the German automaker BMW since 2003. Based on the BMW 3 Series platform, and now in its second generation, BMW designed the X3 in conjunction with Magna Steyr of Graz, Austria—who manufactured all X3s under contract to BMW for the first generation. Production of the second generation vehicle has transferred to BMW’s Spartanburg plant in South Carolina, United States.
Following the X5, the X3 was the second vehicle marketed by BMW as a Sports Activity Vehicle (SAV).
In 2010, 46,000 X3 were produced.
