Costs & verdict
Everyday costs, plus how reliable and safe it is
If you’re buying an BMW X4 with cash, it will cost you several thousand pounds more than an equivalent BMW X3. But, perhaps more importantly, it’s also pricier than its closest rival, the Mercedes GLC Coupé. There are deals to be had, though, not least if you use our New Car Buying service.
Running costs are more impressive; the 20d model averages just over 50mpg in official economy tests, compared with the 46.4mpg of the most efficient GLC Coupé.
