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, a bigger boot with versatile 40/20/40 split-folding rear seats, and cabin quality that rivals the best in its class. The elevated driving position, generous luxury kit, and impressive infotainment system create a premium experience that justifies its positioning as Mercedes' smallest and most affordable SUV.

The driving experience is considerably more competitive than before, with a comfortable ride that handles sharply and a diverse engine lineup ranging from sensible to sensational. Diesel options deliver around 50-53mpg for high-mileage drivers, whilst petrol engines achieve 37-41mpg. The plug-in hybrid offers exceptional official figures but requires careful consideration of real-world usage. However, buyers should be aware of Mercedes' mixed reliability reputation, the GLA 45 S's high fuel costs, and slightly tight rear headroom for taller passengers. Prices are steep compared to rivals, though the captivating infotainment system and overall refinement often justify the premium.

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, those prioritising reliability, or taller passengers requiring generous rear headroom.


Comparison vs Key Rivals



The Verdict

You should buy the GLA-Class if: You seek a premium compact SUV with cutting-edge technology, sharp handling, and luxury cabin quality, or value style and infotainment sophistication.

Consider alternatives if: You're budget-conscious, prioritise reliability, or require generous rear headroom for taller passengers.

Competitive Position: The Mercedes-Benz GLA-Class (2020-present) is a strong contender in the compact luxury SUV segment, offering superior infotainment, sharp handling, and premium cabin quality. Whilst it commands a price premium over rivals like the Audi Q3 and BMW X1, its captivating technology and athletic styling justify the investment for those prioritising luxury and innovation. The Volvo XC40 matches it for user satisfaction and overall rating, whilst the BMW X1 offers slightly better value. However, the GLA's superb infotainment system and driving dynamics make it the choice for tech-savvy buyers willing to pay for premium quality and cutting-edge features.
