Mercedes GLA-Class H247 — Overview
The H247 is the second generation of the Mercedes-Benz GLA, introduced in 2020 as the successor to the X156.
It shares the MFA2 platform with the A-Class and GLB, offering a taller, more practical body with improved interior space and technology. A 2023 facelift brought 48V mild-hybrid assistance to all petrol engines, along with updated MBUX infotainment. The range spans from the Renault-sourced 1.3-litre M282 petrol four-cylinder to the hand-built M139 in the 421 bhp AMG GLA 45 S.

Market Intelligence
The OM654 diesel engine family generated 520 real UK enquiries in 2025 [MB-VERIFIED], concentrated on the GLA 200 d and 220 d as these compact SUVs continue to serve fleet and private buyers alike.
Best & Worst Engines
Best Diesel Overall
OM654.920 (GLA 220 d, 190 bhp)
“The 2.0-litre four-cylinder diesel offers genuine performance (7.3s to 60mph) with excellent fuel economy and the reliability of Mercedes' modern common-rail system — AdBlue system maintenance is its only real demand.”
Who it's for: buyers who want diesel torque and economy without the older OM651's issues.
Best Petrol Overall
M260.920 (GLA 250, 224 bhp)
“The 2.0-litre turbo four is the sweet spot of the petrol range — punchy, responsive, and without the M139's high-strung complexity. It's the engine that makes the GLA feel genuinely quick.”
Who it's for: buyers who want performance without the AMG premium.
Highest Risk
M282.914 (GLA 180/200, 1.3L)
“The Renault-sourced 1.3-litre turbo is a clever engine, but its small displacement means it works hard in a 1.5-tonne SUV — turbocharger and timing chain wear are emerging as concerns on higher-mileage examples.”
Who it's for: buyers who prioritise running costs and accept the smaller engine's limitations.
Most Expensive Failure
M139.980 (AMG GLA 45 S, 421 bhp)
“The hand-built 2.0-litre turbo delivers 421 bhp — the most powerful four-cylinder in production — but high-strung engines come with high-strung costs. Turbo and cooling system failures are expensive, and specialist labour is essential.”
Who it's for: AMG enthusiasts with the budget to maintain the most powerful four-cylinder ever made.
Best Value
OM654.920 (GLA 200 d, 150 bhp)
“The entry-level diesel offers genuine economy (50+ mpg) with the same core engine as the more powerful 220 d — and significantly lower purchase prices. It's the sensible choice for high-mileage drivers.”
Who it's for: buyers who want diesel economy without the V6 or AMG premium.
Most Overlooked
M260.920 (AMG GLA 35, 306 bhp)
“Often overshadowed by the 45 S, the GLA 35 offers genuine AMG performance (306 bhp) with significantly lower running costs than its big brother — and the 48V mild-hybrid system adds a useful 13 bhp boost.”
Who it's for: buyers who want AMG credentials without the 45 S's running costs.
Mercedes GLA-Class H247 — Ownership Economics
The H247 rule
A £2,800–£5,000 OM654 recon against a £15,000–£30,000 H247 sits at 10–30% of the car's value — well within our 70% Mercedes-Benz threshold. Even the £5,000–£11,000 M139 V8-equivalent four-cylinder recon against a £35,000–£55,000 AMG GLA 45 S is just 15–30% — a viable spend on a well-maintained example. These are modern, valuable cars; replacement almost always makes financial sense.
Key Takeaways

GLA 200 d (OM654) — cheapest diesel recon, best fuel economy.
Which H247 Costs Most To Own?
