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 upon 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 those preferring SUVs over hatchbacks. The GLA is the least expensive SUV with a three-pointed star, positioned between the A-Class hatchback and larger GLB.

The driving experience is much more competitive than before, with a comfortable ride and fairly sharp handling, though the suspension remains slightly fidgety at low speeds. Engine options range from sensible to sensational, with most delivering good fuel economy. The superb infotainment system with its 10.25-inch displays, voice activation, and Apple CarPlay/Android Auto integration is a standout feature. Available powertrains include 1.3-litre petrol units, a 2.0-litre diesel, and a plug-in hybrid with 43-45 miles of electric range. AMG variants offer thrilling performance with up to 415bhp.

Best for: Tech-savvy buyers seeking premium infotainment, those wanting an affordable Mercedes SUV with multiple powertrain options, and drivers prioritising an elevated driving position with modern styling.

Not ideal for: Buyers concerned about Mercedes reliability, those needing multiple hybrid options, or taller passengers requiring maximum rear headroom.


Comparison vs Key Rivals



The Verdict

You should buy the GLA if: You're seeking an affordable Mercedes SUV with premium infotainment, multiple powertrain options, and modern styling, or you prefer an elevated driving position with competitive handling.

Consider alternatives if: You prioritise reliability above all else, require multiple hybrid options, or need maximum rear headroom for taller passengers.

Competitive Position: The Mercedes-Benz GLA-Class (2020-present) is a strong contender in the compact premium SUV segment, offering excellent value and a superb infotainment system that rivals struggle to match. Whilst the Volvo XC40 edges ahead in user satisfaction and the Audi Q3 offers broader powertrain choices, the GLA's affordability, sharp handling, and captivating technology make it a compelling choice. The range of engines from sensible to sensational, combined with competitive pricing, positions it well against the BMW X1 and Audi Q3. For tech-savvy buyers willing to accept Mercedes' reliability reputation, the GLA represents outstanding value in the premium compact SUV market.
