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

Pros	Cons
Still available with diesel and petrol engines	Mercedes still has an iffy reputation for reliability
Much sharper to drive than its predecessor	There is only one hybrid version
Superb infotainment system	Headroom is a little tight in the back

Quick Summary

The Mercedes-Benz GLA-Class (2020-present) is a vastly superior second-generation offering that improves significantly on its predecessor. The styling is now plausibly SUV-like rather than resembling a jacked-up hatchback, whilst the chunkier dimensions translate to more interior space and a bigger, more versatile boot. Cabin quality is competitive within its class, and the elevated driving position appeals to many buyers seeking an alternative to the A-Class hatchback. The GLA offers a varied powertrain lineup, ranging from sensible to sensational, with most engines delivering respectable fuel economy.

The driving experience is much more competitive than before, with a comfortable ride and fairly sharp handling, though some models feel slightly fidgety at low speeds. The captivating infotainment system is a standout feature that sets the Mercedes apart from rivals. Available engines include 1.3-litre petrol units, a 2.0-litre diesel, and a plug-in hybrid option with 43-45 miles of electric range. For those seeking extra performance, AMG versions deliver 302bhp or 415bhp respectively. Whilst more kit could be included as standard at nearly £40,000, the GLA's overall package makes it a compelling choice in the compact SUV segment.

Best for: Buyers seeking a premium compact SUV with excellent infotainment, those preferring diesel or petrol engines, and drivers wanting a more spacious alternative to a hatchback.

Not ideal for: Those prioritising maximum reliability, buyers needing multiple hybrid options, or taller passengers requiring generous rear headroom.


Comparison vs Key Rivals



The Verdict

You should buy the GLA if: You're seeking a premium compact SUV with excellent infotainment, prefer diesel or petrol engines, or want a more spacious alternative to a hatchback.

Consider alternatives if: You're prioritising maximum reliability, need multiple hybrid options, or require generous rear headroom for taller passengers.

Competitive Position: The Mercedes-Benz GLA-Class (2020-present) is a compelling contender in the compact premium SUV market, offering excellent infotainment, sharp handling, and a varied powertrain lineup. Whilst the Volvo XC40 edges ahead with slightly higher user ratings and the BMW X1 offers a wider powertrain selection, the GLA's superb technology and improved driving dynamics make it a strong choice. Its good availability of deals and competitive pricing position it well against rivals, particularly for buyers valuing premium cabin quality and cutting-edge infotainment systems.
