BMW X4 M review

Running costs? Well, if you get more than low 20s to the gallon, you’re a saint. BMW claims a reasonable 26.9mpg. In real-world driving, you’re unlikely to see a palpable saving versus the more soulful V8-powered GLC 63, in our experience. CO2 ratings of 239g/km mean a £1,185 bill. 

The X4 M Competition certainly comes with plenty of kit, but at £80,000, it costs a huge amount of money for a machine with such little bandwidth. There are a lot of better ways to spend such a hefty chunk of dosh.
