Mercedes-Benz GLE Coupé Review (UK)

Mercedes-Benz sells the GLE Coupé in the UK as the sloped-roof version of the GLE, and the range was reworked for 2026. This review sets out what Mercedes-Benz UK currently publishes for the car — the engines, the official WLTP figures, the weights and the towing limits — then puts the numbers that actually decide the monthly cost next to them: first-year road tax, the £40,000 list-price supplement, and the warranty terms.

1. Vehicle Overview

The GLE Coupé shares its mechanical package with the GLE but trades roofline and boot shape for a lower, tapered profile. Mercedes-Benz UK lists three core powertrains: the GLE 350 d and GLE 450 d, both 3.0-litre six-cylinder diesels with 48-volt mild-hybrid assistance, and the GLE 450 e, a six-cylinder petrol plug-in hybrid. Mercedes-AMG adds the GLE 53 in mild-hybrid and plug-in hybrid form, plus the V8 GLE 63 S.

The 2026 revisions are substantial on the cabin and software side rather than the chassis. Mercedes-Benz UK describes a new dashboard with a third 12.3-inch screen embedded for the front passenger, the MBUX Superscreen running three displays under one glass surface, the Mercedes-Benz Operating System (MB.OS), an illuminated outline around the radiator grille and DIGITAL LIGHT headlights. Auto Express reported on 5 August 2026 that the facelifted range keeps diesel power — which is unusual at this size and price — and that the Coupé opens at £82,995 in Urban Edition trim with the 350 d engine.

2. What the GLE Coupé costs in the UK

There is a genuine disagreement between sources here, and it is worth stating rather than smoothing over. Mercedes-Benz UK’s own specification page lists the plug-in hybrid as the GLE 450 e 4MATIC. UK retail price lists, including the one published by Carwow, are still built around the earlier GLE 350 de (diesel plug-in hybrid) and GLE 400 e designations alongside the 450 d. Both sets of figures are real; they describe the order book at different moments. Treat the prices below as the retail picture and confirm the exact engine designation on a dealer quotation.

Carwow puts the published RRP span at £79,995 to £97,495, quotes monthly finance from £1,002 and lists used GLE Coupés from £34,499 — a reminder that the first owner absorbs a very large share of this car’s depreciation. Auto Express’s £82,995 entry price for the facelifted Coupé sits around £3,000 above the equivalent GLE SUV, which it puts at £79,995.

3. Key Specifications (GLE Coupé)

All figures in this table are taken from Mercedes-Benz UK’s published technical data for the GLE Coupé, read on 1 October 2026.

One oddity is worth flagging: Mercedes-Benz UK publishes the same combined economy and CO₂ figures — 38.2 mpg and 194 g/km — for both the 350 d and the much more powerful 450 d, including the individual WLTP sub-cycle rows (24.2 mpg low, 40.4 mpg medium, 46.4 mpg high, 39.3 mpg extra high). WLTP figures legitimately move with wheel size and options, so check the figures on the specific configuration you are quoted rather than assuming the two diesels are identical to run.

4. Exterior Design

The Coupé is 4,940 mm long, 2,018 mm wide excluding mirrors (2,164 mm with them) and 1,729 mm tall in diesel form — a large car by any measure, and wide enough that multi-storey bays and narrow lanes need thought. The plug-in hybrid sits 2 mm lower at 1,727 mm; the AMG models are lower again at 1,717 mm. Turning circle is 11.87 m on the standard cars and 12.4 m on the AMGs.

For 2026 Mercedes-Benz UK highlights the illuminated outline around the radiator grille and DIGITAL LIGHT headlights with a star pattern. AMG Line specification is standard across the Coupé range, so the sportier bumpers and detailing are not an extra-cost decision as they are on some rivals.

5. Interior, Comfort & Materials

The headline change inside is the new dashboard. Mercedes-Benz UK describes a third 12.3-inch screen embedded for the front passenger, joining the driver display and central touchscreen; in MBUX Superscreen form the three displays merge under a single glass surface, giving the front passenger their own control area for media, apps and video calls. A fifteen-speaker Burmester 3D surround sound system with Dolby Atmos is offered.

All versions are five-seaters with five doors. The sloping roof is the trade-off for the styling: this is the body style to shortlist if rear headroom and a square boot opening matter less to you than the profile. Test rear-seat access and child-seat fitment in person rather than from the dimensions, because the roofline is exactly where a tape measure misleads.

6. Features & Infotainment

The 2026 car runs the Mercedes-Benz Operating System (MB.OS), which Mercedes-Benz describes as integrating the whole vehicle and carrying the latest generation of driver-assistance systems. In practice the things to check on a quotation are which assistance systems are standard on your chosen trim rather than bundled into an options pack, and whether connected services carry a subscription after an initial period — both vary by market and by model year.

7. Safety & Ratings

This section needs care, because the honest answer is more complicated than a star count. Euro NCAP tested the Mercedes-Benz GLE in 2019 and published a five-star result. The scores were 91% for adult occupant protection, 90% for child occupant protection, 78% for vulnerable road users and 78% for safety assist. The tested car was a GLE 350 d 4MATIC in AMG Line trim, left-hand drive, with a kerb weight of 2,235 kg.

Two caveats follow directly from Euro NCAP’s own assessment page. First, the Coupé is covered: Euro NCAP lists the rating as applying to the GLE 300 d, GLE 350 d, GLE 400 d and GLE 450 4MATIC variants, each annotated “incl. Coupé”, in both left- and right-hand drive. Second, that rating has expired. Euro NCAP’s validity table records the rating published on 3 July 2019, annual reviews in 2020 and 2021, and the rating expired on 1 January 2026. The current UK engines — 450 d, 450 e and the AMG versions — do not appear in that variant list at all.

Expiry is not a downgrade and it is not evidence the car has become less safe; Euro NCAP’s test protocols simply move on, and an older result is no longer comparable with cars rated under the current scheme. The practical consequence for a buyer is that there is no current independent crash rating for the GLE Coupé you can order today, so judge the safety specification on the equipment list and on what is standard rather than optional.

8. Driving Performance

Every GLE Coupé is all-wheel drive with a nine-speed automatic — 9G-TRONIC on the standard cars, AMG SPEEDSHIFT TCT 9G on the AMGs. The spread of performance is wide. The 350 d reaches 62 mph in 6.2 seconds; the 450 d does it in 5.3 seconds on 750 Nm of torque, and the 450 e in 5.6 seconds. The 450 e is the heaviest of the three at 2,778 kg against 2,478 kg for the diesels, a 300 kg penalty for the battery and motor.

True Motion Auto does not road-test cars, so we do not make ride or handling claims of our own. For an external view, Carwow’s reviewer Mat Watson scores the GLE Coupé 7 out of 10 and frames it as giving up some of the GLE’s space and practicality for the styling, while remaining a very good large SUV underneath. Carwow also notes around 40 mpg is achievable in the 450 d when driven gently, against the 38.2 mpg official combined figure.

9. Economy, Electric Range & Charging

The 450 e is the only GLE Coupé you can drive on electricity alone. Mercedes-Benz UK publishes a WLTP electric range of 63 miles, an Equivalent All-Electric Range of 65 miles, a usable battery capacity of 25.72 kWh and a combined energy consumption of 21.5 kWh/100km.

A 60 kW DC ceiling is modest next to a full electric car, but on a plug-in hybrid with a 25.72 kWh pack it still means a useful top-up inside a coffee stop. The important money point is the one that catches out plug-in hybrid owners generally: the 91.2 mpg combined figure assumes a battery that starts full. Drive the car on petrol with a flat battery and you are moving nearly 2.8 tonnes on a 3.0-litre six, and the real figure will be a fraction of that. If you cannot charge at home or at work most nights, the diesel is very likely the cheaper car — one of several plug-in hybrid ownership mistakes that turn a tax-efficient company car into an expensive private one. If you are still deciding between the formats, our guide to hybrids, plug-in hybrids and full EVs sets out where each one actually saves money.

10. Road tax and the £40,000 supplement

This is where the powertrain choice has its sharpest financial consequence, and it is a four-figure difference in the first year alone. The table applies the current GOV.UK vehicle tax rate tables to the CO₂ figures Mercedes-Benz UK publishes for each version. Every GLE Coupé has a list price above £40,000, so every one of them also pays the additional rate of £440 a year on top of the £200 standard rate, for five years from the second time the vehicle is taxed.

The gap between the plug-in hybrid and the diesels in year one is £3,285, and between the 450 e and the GLE 63 S it is £5,555. For a company-car driver the plug-in hybrid’s advantage widens again, because benefit-in-kind bands are set by CO₂ and electric range — the mechanism we explain in our guide to the best company cars in the UK. For a private buyer paying cash, the first-year rate is usually folded into the on-the-road price, so check how your quotation presents it.

11. Practicality, Towing & Everyday Usability

Boot space is 655 litres on the diesel and AMG mild-hybrid versions. The plug-in hybrids drop to 505 litres — a 150-litre loss to the battery, and the single biggest practical reason to think twice about the 450 e if you regularly travel fully loaded.

A 2,700 kg braked towing limit is a real strength, and the AMG versions are rated higher still — 3,500 kg for the GLE 53 mild hybrid and the GLE 63 S, 3,300 kg for the GLE 53 HYBRID. Before you plan around those numbers, check what your licence actually permits: the rules depend on when you passed your test and on the combined weight of car and trailer, which we set out in our guide to UK towing licence rules. With a gross vehicle weight of 3,130 kg on the diesel and 3,310 kg on the plug-in hybrid, a GLE Coupé plus a heavy caravan is well into the territory where the combination limit, not the car, is the constraint.

12. Warranty & Maintenance

Mercedes-Benz UK states that every new Mercedes-Benz car sold through its network comes with a comprehensive three-year warranty, and that Roadside Assistance is included free of charge for three years. That is shorter than the five- and seven-year warranties offered by some mainstream brands, and worth pricing against an extended-warranty quotation if you intend to keep the car beyond year three.

For the plug-in hybrid versions, Mercedes-Benz Cars UK’s High Voltage Battery Certificate covers technical malfunction of the high-voltage battery arising directly from an inherent manufacturing fault. The conditions matter: maintenance must have been carried out to Mercedes-Benz specification, there must be no chip tuning, and repairs under the certificate must be carried out by a Mercedes-Benz approved repairer. Keep the service record intact if you want that cover to survive to a second owner.

13. Mercedes-AMG GLE Coupé: 53 and 63 S

Mercedes-AMG offers three versions of the Coupé, and the 2026 line-up includes a plug-in hybrid AMG, which changes the tax position of a 585 hp car dramatically.

The GLE 53 HYBRID is the interesting case on cost. It is quicker to 62 mph than the mild-hybrid 53 (4.5 seconds against 4.9), yet its 88 g/km weighted CO₂ puts it in a £280 first-year VED band against £4,850 for the mild hybrid — and it carries a 25.28 kWh battery with 55 miles of WLTP electric range. The price for that is weight, at 2,825 kg, and the same 505-litre boot as the other plug-in hybrids.

14. Comparison with Rivals

The GLE Coupé’s natural comparisons are the other large, coupé-profile or style-led premium SUVs. We have full UK reviews of two of its closest competitors: the Audi Q8, which Carwow currently lists from £71,744, and the Porsche Cayenne, which is also sold in a coupé body. The BMW X6 is the most direct rival of all on concept.

15. Pros & Cons

Pros

Six-cylinder diesel choice is still available, and the 450 d pairs 367 hp with 750 Nm

GLE 450 e combines 435 hp system output with 63 miles of WLTP electric range and a £135 first-year VED bill

2,700 kg braked towing as standard, up to 3,500 kg on the AMG mild hybrids

Substantially upgraded 2026 cabin: MB.OS, a third front-passenger display, MBUX Superscreen

655-litre boot on the non-plug-in versions is competitive for a coupé-profile SUV

Cons

No current independent crash rating — the 2019 Euro NCAP result expired on 1 January 2026

Plug-in hybrid loses 150 litres of boot space and adds 300 kg over the diesel

Diesel versions face a £3,420 first-year VED charge against the 450 e’s £135

Every version pays the £40,000 list-price supplement, so years two to six cost £640 a year

Three-year warranty is short for the money

Used examples from £34,499 show how steeply the first owner absorbs depreciation

16. Overall Rating

4.0 / 5

17. Final Verdict

The GLE Coupé is a confident, well-equipped large SUV whose 2026 update lands mostly on the cabin and the software, and whose powertrain range is broader than almost anything else at this size — including diesels that rivals have abandoned. The decision that matters is not trim but powertrain, and road tax makes it for you. If you can charge regularly, the 450 e is the rational choice: 435 hp, 63 miles of electric range and £135 of first-year VED instead of £3,420, at the cost of 150 litres of boot and 300 kg. If you cannot charge, or you tow and load the car heavily, the 450 d is the honest answer and you should budget for the tax. What a buyer should weigh against the badge is the absence of a current crash rating and a three-year warranty on an £83,000 car.
