Overview

Mercedes-Benz GLE C167 — Overview

The Mercedes-Benz GLE C167 is the coupé SUV variant of the third-generation GLE-Class, introduced in 2019 as the successor to the C292.

Built on the same V167 platform as the standard GLE SUV, the C167 brings a more dramatic roofline, sportier styling and a driving experience that prioritises on-road dynamics. Engine choice spans the OM656 2.9-litre straight-six diesel (GLE 350 d/400 d), the M256 3.0-litre inline-six petrol with EQ Boost (AMG GLE 53), the M177 4.0-litre twin-turbo V8 (AMG GLE 63/63 S), plus four-cylinder options including the M264 petrol and M274 plug-in hybrid. A facelift in 2023 introduced the OM654 2.0-litre diesel (GLE 300 d), the M256.925 2.5-litre six-cylinder (GLE 450) and the OM656 370 bhp diesel (GLE 450 d).

Best & Worst Engines

Thin-Data Summary

“Thin-Data Fallback mode applied — compressed to a single paragraph. Best & Worst Engines: The C167's engine range spans four distinct powertrain families. At the top for everyday usability sits the OM656 3.0-litre straight-six diesel — the GLE 400 d (330 bhp) offers effortless torque and proven durability in the wider Mercedes lineup, making it the most sensible choice for high-mileage buyers. The GLE 350 d (272 bhp) is a more affordable entry point with the same robust architecture. Among petrols, the M256 3.0-litre inline-six in the AMG GLE 53 (435 bhp) is a masterpiece — smooth, responsive with EQ Boost assistance, and significantly more affordable to run than its V8 stablemate. The M264 2.0-litre turbo (GLE 350) offers the lowest running costs but lacks the effortless delivery of the six-cylinder cars. The M274 plug-in hybrid (GLE 350 e) is a niche proposition — fuel economy is strong but the complexity of the hybrid system adds potential failure points and higher replacement costs. The M177 in the AMG GLE 63 and 63 S (571–612 bhp) is brutal and addictive, but demands deep pockets for fuel, tyres and specialist maintenance. For most buyers, the GLE 400 d (OM656) or AMG GLE 53 (M256) represent the sweet spot between capability, economy and running costs. Who it's for: buyers who want the sweet spot between coupé SUV presence and running-cost sanity.”

The C167 rule

A £4,500–£7,000 OM656 recon against a £30,000–£60,000 C167 sits at just 7.5–23% of the car's value — well within Mercedes-Benz's 70% threshold. Even a £9,000–£16,000 M177 recon on a £50,000–£80,000 AMG GLE 63 sits at 11–32%. The GLE Coupé's strong retained values mean engine replacement is almost always financially viable. For OM654 four-cylinder diesels, the economics are even more favourable — a £4,000 recon on a £35,000 example is just 11%. Value the car, but know that the C167 holds its value well.
