BMW X4 (2018-present) Pros and Cons

Pros	Cons
Coupe-like looks stand out from the SUV crowd	Not as practical as an X3, although that's hardly surprising
Drives well, even if you choose one of the less powerful versions	No plug-in hybrid version
The xDrive30d offers great performance and reasonable economy	Lacks a small petrol engine

Quick Summary

The BMW X4 (2018-present) is a divisive yet compelling coupe-SUV that challenges conventional thinking about high-riding vehicles. This second-generation model combines striking styling with genuine driving enjoyment, offering a bolder alternative to traditional SUVs. With 525 litres of boot space (1,430 litres seats down), it sacrifices only modest practicality compared to the X3, making it suitable for those who don't require maximum rear headroom. All models feature xDrive four-wheel drive and eight-speed automatic transmission, with M Sport suspension as standard, delivering an engaging driving experience across the range.

The engine lineup spans from the entry-level 190hp xDrive20d to the thrilling 510hp M Competition, which accelerates to 62mph in 4.1 seconds—quicker than a Porsche 911 Carrera. The xDrive30d strikes an excellent balance, delivering 5.8-second 0-62mph performance whilst achieving over 40mpg in real-world driving. Running costs vary considerably across the range, with the xDrive20d achieving 42.2-45.6mpg officially. All X4s exceed the £40,000 threshold for enhanced road tax, and BMW servicing is available via monthly payment plans. The X4 M Competition offers thrilling performance in a more practical package than traditional M cars, though it demands higher running costs.

Best for: Buyers seeking distinctive styling, engaging driving dynamics, and those who prioritise design over maximum practicality; performance enthusiasts wanting M Car thrills in a taller package.

Not ideal for: Those requiring maximum boot space and rear headroom, buyers seeking plug-in hybrid options, or those wanting small petrol engine efficiency.


Comparison vs Key Rivals



The Verdict

You should buy the X4 if: You value distinctive styling, enjoy engaging driving dynamics, and don't require maximum practicality; or you seek M Car performance in a taller, more practical package.

Consider alternatives if: You prioritise maximum boot space and rear headroom, require plug-in hybrid options, or prefer traditional SUV practicality over coupe aesthetics.

Competitive Position: The BMW X4 (2018-present) occupies a unique position in the premium compact SUV segment, offering bold coupe-inspired design that stands apart from conventional rivals. Whilst the Porsche Macan and Mercedes-Benz GLC Coupe provide alternative premium options, the X4 delivers compelling driving dynamics and striking styling at a competitive price point. The xDrive30d variant offers an excellent balance of performance and economy, making it particularly appealing. However, buyers seeking maximum practicality or plug-in hybrid technology may find the Range Rover Evoque or Mercedes-Benz GLC-Class more suitable, though the X4 remains the driver's choice for those prioritising engagement and distinctive aesthetics.
