The first-generation Mercedes GLA, produced from 2013 to 2020, blends compact crossover versatility with the brand’s signature luxury. Built on the A-Class platform, it offers elevated styling and premium features, making it a popular choice in the used market despite some compromises in practicality and ride quality.
Design and Visual Appeal
The GLA stands out with its bold, muscular exterior that differentiates it from standard hatchbacks. Its higher ride height and rugged lines give it genuine crossover presence, appealing to buyers seeking a fashionable daily driver. Pre-facelift models from 2013-2017 have a sleeker profile, while the 2017 update added chunkier bumpers and a more aggressive front grille for enhanced road presence.
Inside, the cabin delivers Mercedes quality with durable materials and a driver-focused layout. Early versions feature a functional dashboard, upgraded in the facelift with better infotainment and ambient lighting options. Space is decent upfront, but rear legroom lags behind taller rivals, suitable for couples or small families rather than larger groups.
Engine Lineup and Performance
A variety of four-cylinder engines power the GLA, balancing efficiency and power. Petrol options include the entry-level 1.6-litre GLA 180 (122hp) and punchier 2.0-litre GLA 250 (211hp), with the high-performance GLA 45 AMG delivering 381hp for thrilling acceleration.
Diesels dominate for economy: the 2.0-litre GLA 200d (136hp) achieves around 46-55mpg in real-world driving, while the 220d (170hp or 175hp post-facelift) offers strong torque for overtaking. Most models pair with a smooth seven-speed automatic, preferred over the manual for relaxed cruising; 4MATIC all-wheel drive is available on higher trims for better traction.
| Engine | Power | Economy (WLTP mpg) | 0-62mph (sec) |
|---|---|---|---|
| GLA 180 Petrol | 122hp | 40.4 | 9.0 |
| GLA 200 Petrol | 163hp | 39.8 | 8.1 |
| GLA 200d Diesel | 136hp | 46.3 | 9.5 |
| GLA 220d Diesel | 175hp | 47.9 | 8.1 |
| GLA 45 AMG | 381hp | 31.0 | 4.4 |
Performance is ample for most, with diesels excelling on motorways. The AMG variant transforms the GLA into a hot hatch rival, though it’s rare and pricier used.
Trims, Equipment, and Recommended Picks
Key trims include SE (entry-level with basics like sat-nav), Sport (sportier looks), and AMG Line (premium styling and tech). Special editions like WhiteArt (2017) and Urban (2018) add unique paint and extras. Post-2017 facelifts bring standard Apple CarPlay and improved multimedia.
- Best for value: GLA 200d SE – Efficient diesel with low running costs and solid kit.
- Best equipped: GLA 220d 4MATIC WhiteArt Edition – Loaded with options, AWD grip.
- Best for enthusiasts: GLA 45 AMG – Explosive power and handling upgrades.
Inspect option packs carefully; popular ones include parking aids and leather upgrades. Facelifted models (2017+) are preferable for refinements.
Driving Dynamics and Comfort
The GLA handles competently with precise steering, though its low centre of gravity feels more hatchback than SUV. Ride quality is firm, especially on AMG Line’s larger wheels, transmitting road imperfections. It’s stable at speed but lacks the plushness of some competitors.
4MATIC versions improve wet-weather confidence without sacrificing much efficiency. Noise insulation is good, making it a refined motorway companion, though diesel clatter is noticeable under acceleration.
Practicality and Interior Space
Boot space measures 421 litres, expandable to 1,235 litres, adequate for shopping but smaller than rivals like the Audi Q3. Rear seats fold flat easily, but the high loading lip can be awkward. No elevated ‘command’ seating position disappoints some SUV shoppers.
Upfront, seats are supportive with good adjustment; rears suit children or adults on shorter trips. Towing capacity reaches 1,800kg braked on diesels.
Running Costs and Economy
Used prices start around £10,000 for high-mileage early models, rising to £25,000+ for low-mileage facelifts or AMGs. Diesels shine with 45-55mpg, low CO2 (150g/km), and cheap BIK rates. Petrols manage 35-40mpg but suit shorter trips.
Services cost £300-£750; no cambelts needed. Insurance groups 20-45 reflect premium status. Tyres and brakes are pricey replacements.
Reliability and Owner Feedback
Mercedes ranks mid-pack for reliability, with GLA owners praising build quality but noting occasional issues with electronics and transmissions. In surveys, it’s middling, outperforming some rivals in durability but trailing Lexus or Volvo.
Common fixes include diesel particulate filter clogs (high-mileage) and infotainment glitches. Pre-purchase checks for service history are essential.
Comparisons with Key Rivals
| Model | Strengths | Weaknesses vs GLA |
|---|---|---|
| Audi Q3 | Superior interior, ride | Higher price, less agile |
| Range Rover Evoque | Premium feel, off-road | Poor reliability, thirsty |
| BMW X1 | Engaging drive | Firmer ride, costlier |
The GLA wins on style and badge prestige but trails in space and comfort.
