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 second-generation Mercedes-Benz GLA Class (2020-present) marks a significant evolution, transforming into a plausible and practical compact SUV. Based on the improved A-Class, it offers a larger boot and decent rear space, though headroom can be tight for taller passengers. On the road, the GLA provides a more civilised experience, handling well at higher speeds for comfortable motorway cruising, with agile handling thanks to its sportier suspension, though low-speed ride can be fidgety. The cabin impresses with a lofty driving position, luxury features, and advanced digital screens, creating a high-tech and sophisticated atmosphere.

The GLA features a diverse engine lineup, including petrols, diesels, and a plug-in hybrid, catering to various performance and efficiency needs. While new prices are steep compared to rivals like the Audi Q3 and BMW X1, and running costs reflect its premium status, the diesels offer good fuel economy (around 50-53mpg). Insurance groups range widely. Overall, it's a vastly superior offering that deserves its success based on its qualities, including its superb infotainment system and improved driving dynamics.

Best for: Buyers seeking a stylish, sophisticated compact SUV with advanced technology, sharp handling, and a premium interior. Those looking for a wide range of engine options, including high-performance AMG variants, or a plug-in hybrid.

Not ideal for: Budget-conscious buyers due to higher purchase prices and potential running costs. Those prioritising maximum rear headroom or a consistently plush ride at low speeds. Buyers sensitive to potential reliability concerns associated with Mercedes.

The Verdict

You should buy the GLA if: You're looking for a stylish, sophisticated compact SUV with advanced technology, sharp handling, and a premium interior, or if you desire a wide range of engine options, including high-performance AMG variants or a plug-in hybrid.

Consider alternatives if: You are on a strict budget, prioritise maximum rear headroom, seek a consistently plush ride at low speeds, or have concerns about potential reliability.

Competitive Position: The second-generation Mercedes-Benz GLA Class is a highly competitive and vastly improved offering in the compact premium SUV market. It distinguishes itself with sophisticated styling, a luxurious and technologically advanced interior featuring the MBUX infotainment system, and a broad range of engine options, from efficient diesels and a plug-in hybrid to potent AMG variants. While it comes at a higher price point than some alternatives and its low-speed ride can be a bit firm, its agile handling, comfortable motorway cruising, and premium feel make it a compelling choice for buyers seeking a sophisticated and feature-rich compact SUV.
