BMW keeps on filling out its Sport Activity Vehicle line-up, making 2018 a busy year for the brand's SAVs. The X7 will soon act as a new bookend to a range which starts with the X1. A new X5 is imminent, while the second generation X4 is arriving at dealerships. The line-up was recently completed - for now at least - by the X2, a 4,360mm long Range Rover Evoque rival.
