Here we see BMW engineers putting the F25 X3 through some tow testing. This photo was taken on the infamous Großglockner High Alpine Road in Austria. Towing a heavy trailer while on a road with great vertical angles and sharp turns is just par for the course with a BMW SAV driver, so it is nice to see the engineers doing real-world tests for these situations! This next generation X3 will be built in the USA at the Spartanburg, SC plant.
