When it comes to buying an X3 with cash, there’s little to separate it on price from its main rivals. Generous discounts are available from dealers, as well as through our hassle-free New Car Buying service. However, the X3 is predicted to depreciate quite a bit more after three years (as a percentage of its list price) than an Audi Q5, Land Rover Discovery Sport or Porsche Macan. PCP deals are relatively pricey as a result, at least among its premium peers, with higher like-for-like monthly payments than the equivalent Q5.
The xDrive30e plug-in hybrid is the obvious choice for company car buyers, with by far the lowest CO2 emissions in the lineup and a generous company car tax break. If you can keep its battery topped up and run on electric power alone most of the time, you won’t pay much in fuel costs, either. Our pick – the 20d with 48v mild hybrid assistance – still makes sense if you're a higher-mileage driver because its near-50mpg WLTP average economy will trounce the xDrive30e's when its battery has run out. Across the X3’s engine lineup the official fuel economy figures are impressive compared with many of its rivals.
If you go for xLine trim you get 19in wheels, silver side sills, LED front foglights, sports seats and more off-road orientated exterior styling but, unless you’ve a particular desire to upgrade the X3's looks, it isn’t worth the extra money.
M Sport is the next step on the ladder, and offers an even sportier appearance as well as the larger infotainment screen and digital driver display we mentioned earlier. Range-topping M40i and M40d, meanwhile, feature even bigger 20in wheels and upgraded brakes among their upgrades.
