BMW X4 Leaks

We have the first official photos of the BMW X4 SUV – the ‘Lifestyle’ version of the X3 – which we expect to debut at the Shanghai Motor Show this month. We have the first leaked images of the X4 that show a BMW X3 with the same sort of treatment as the X5 got to turn it in to the X6, and create what BMW like to call an SAC – a Sports Activity Coupe.
