The Renault Rafale is a newcomer that sits in the same segment as the X4, but it can’t match the BMW’s premium feel; the same is true for the Citroen C5 X, which doesn’t have the degree of substance to back up the smart looks.
What to look for
Fuel tank
Sport editions come with a 68-litre fuel tank, but the M Sport and M Sport X have a 59-litre capacity.
Extras
The options list is long and includes wireless phone charging, a heated steering wheel, adaptive cruise control and 360-degree cameras.
Tyres
M Sport models are fitted with run-flat tyres, but the Sport features conventional rubber. A space-saver spare will fit under the boot floor.
Towing
An integrated electric towbar was offered as an option. All X4s, whether petrol or diesel, have a braked towing capacity of 2,000kg.
Interior
Taken from the X3, the X4’s dash is a model of clarity, as you’d expect. The M40i and M40d have digital instrumentation. There’s a good balance of touchscreen and buttons or dials to control all the various operations, while the infotainment set-up is one of the best that you’ll find.
The choice of materials is excellent and so is the design, while front-seat space and comfort are also impressive. There’s decent room in the back seats as well, although the car’s sloping roofline means headroom is compromised and so, potentially, is boot space. This comes in at 1,430 litres with the back seats folded down, or 525 litres if they’re in use.
Running costs
As with all BMWs, the X4 comes with Condition-Based Servicing, which is a variable maintenance programme that tells the driver when work is required, based on oil levels, wear rates of individual components and how hard the vehicle is driven.
