Mercedes-Benz GLA-Class (2020-present) Pros and Cons

Pros	Cons
Muscular and athletic styling	Mercedes has an iffy reputation for reliability
Sharp to drive	The 45 S is very expensive to fuel
Superb infotainment system	Headroom is a little tight in the back

Quick Summary

The Mercedes-Benz GLA-Class (2020-present) is a compact luxury SUV that represents a significant improvement over its predecessor. With muscular, athletic styling that genuinely looks like a proper SUV rather than a jacked-up hatchback, the second-generation GLA offers more interior space and a larger, more versatile boot. The cabin quality rivals the best in its class, featuring an elevated driving position, generous luxury equipment, and an impressive array of digital screens that create a sophisticated, hi-tech atmosphere. A varied line-up of four-cylinder turbo engines ranges from sensible to sensational, with petrols from 134bhp to 415bhp, efficient diesels, and a plug-in hybrid option.

The driving experience is considerably more competitive than before, with a comfortable ride that flattens out at higher speeds and sharp handling that contains body roll effectively. The standout feature is the captivating infotainment system, which impresses tech enthusiasts and general users alike. Fuel economy varies by engine choice, with diesels returning around 50-53mpg and petrols achieving 37-41mpg. However, as a Mercedes, the GLA commands premium pricing and carries higher running costs, including insurance groups up to 44 and potential luxury tax implications. Reliability concerns are worth considering before purchase.

Best for: Buyers seeking a premium compact SUV with cutting-edge technology, sharp handling, and luxury cabin quality; those who value style and infotainment sophistication.

Not ideal for: Budget-conscious buyers concerned about reliability, those prioritising maximum rear headroom, or drivers seeking the lowest fuel costs in the segment.


Comparison vs Key Rivals



The Verdict

You should buy the GLA-Class if: You're seeking a premium compact SUV with cutting-edge technology, sharp handling, and luxury cabin quality, or you value style and infotainment sophistication above all else.

Consider alternatives if: You're budget-conscious and concerned about reliability, prioritise maximum rear headroom, or seek the lowest fuel costs in the segment.

Competitive Position: The Mercedes-Benz GLA-Class (2020-present) is a strong contender in the premium compact SUV market, offering muscular styling, sharp handling, and an exceptional infotainment system that sets it apart from rivals. Whilst the Volvo XC40 edges ahead on user satisfaction and the Audi Q3 offers comparable quality at potentially lower cost, the GLA's captivating technology and athletic driving dynamics make it a compelling choice for those willing to pay a premium. The BMW X1 provides similar overall appeal, but the GLA's distinctive design and infotainment excellence give it a unique edge for tech-focused buyers.
