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 distinctive coupe-SUV that challenges conventional thinking about high-riding vehicles. This second-generation model combines the practicality of an SUV with the bold styling of a coupe, offering 525 litres of boot space with seats up and 1,430 litres with them folded. Whilst slightly less spacious than the X3, the difference is negligible for most users. The X4 features xDrive all-wheel drive as standard and an eight-speed automatic transmission across the range, with M Sport suspension providing a more driver-focused experience than its pragmatic sibling.

The engine lineup spans from the entry-level 190hp xDrive20d to the formidable 510hp M Competition, which accelerates to 62mph in just 4.1 seconds—quicker than a Porsche 911 Carrera. The xDrive30d strikes an excellent balance, delivering sparkling performance with a 5.8-second 0-62mph time whilst achieving over 40mpg. All models feature finely weighted steering and responsive handling. Running costs vary considerably across the range, with the xDrive20d achieving 42.2-45.6mpg and the xDrive30d returning 38.2-40.9mpg. Servicing is available via monthly payment plans, though connected services require subscriptions after three years.

Best for: Drivers seeking a distinctive, driver-focused SUV with bold styling, those wanting performance without sacrificing practicality, and buyers who appreciate the xDrive30d's balance of power and economy.

Not ideal for: Those prioritising maximum boot space, buyers seeking plug-in hybrid options, or those wanting a small petrol engine alternative.


Comparison vs Key Rivals



The Verdict

You should buy the X4 if: You seek a distinctive, driver-focused SUV with bold styling, want performance without sacrificing practicality, or appreciate the xDrive30d's balance of power and economy.

Consider alternatives if: You prioritise maximum boot space, seek plug-in hybrid options, or want a small petrol engine alternative.

Competitive Position: The BMW X4 (2018-present) is a compelling choice in the coupe-SUV segment, offering distinctive styling that stands out from conventional SUVs. Whilst the Mercedes-Benz GLC-Class edges ahead with a marginally higher overall rating and better value proposition, the X4 excels in driving dynamics and user satisfaction. The Porsche Macan and Range Rover Evoque are strong competitors, but the X4's xDrive30d engine delivers an exceptional balance of performance and economy. For buyers valuing driver engagement and bold aesthetics over maximum practicality, the X4 represents an excellent choice in an increasingly popular market segment.
