Did you see the photographs of the BMW iX on our feed this week? The answer to that is no, because we didn’t post any. Sharing images of a car so hideous would violate the Ti code of conduction. So rather than write about an electric SUV in which I have almost no interest whatsoever, I thought I’d write instead about a BMW that I like very much. The 5 Series has recently been facelifted and the 523bhp M550i xDrive is now available in the UK.
