What Does the New 627bhp V8 Bring to the Mercedes‑AMG GLE 63 and GLS 63?

Mid‑life refresh for Mercedes‑AMG’s flagship SUVs

Mercedes‑AMG has announced a mid‑life update for its top‑end GLE 63 and GLS 63 models. Both vehicles, positioned as the most powerful variants in the GLE and GLS families, now receive a brand‑new engine and a suite of subtle refinements aimed at keeping the models competitive in the high‑performance SUV segment.

New flat‑plane crank twin‑turbo V8

The heart of the update is a flat‑plane crank twin‑turbocharged V8 that delivers 627 brake‑horsepower. This engine replaces the previous generation’s power unit and is expected to provide a more immediate throttle response and a distinctive exhaust note, hallmarks of AMG’s performance philosophy. The flat‑plane design, unlike the traditional cross‑plane layout, allows for a smoother power delivery and contributes to the vehicle’s sporty character.

What the power boost means for drivers

With 627 bhp now on tap, the GLE 63 and GLS 63 continue to sit at the top of AMG’s SUV hierarchy. While the exact performance figures such as 0‑60 mph times have not been disclosed in the source material, the substantial increase in power suggests improved acceleration and overtaking capability, especially in the larger GLS 63, which benefits from its extra size without compromising on performance.

Styling and equipment tweaks

Alongside the mechanical overhaul, AMG has introduced a series of mid‑cycle visual updates. These include refreshed front and rear bumpers, subtle changes to the radiator grille, and new alloy wheel designs that underscore the models’ sporty intent. Inside the cabin, AMG‑specific trim and upgraded infotainment options reinforce the premium feel expected of Mercedes‑AMG offerings.

AMG’s electric ambition – a glance at the upcoming GT 4‑Door

At the same time Mercedes‑AMG is hinting at an electric future. Recent commentary suggests that AMG may soon reveal an all‑electric GT 4‑Door, a vehicle intended to take on established high‑performance EVs such as the Porsche Taycan. While details remain scarce, the prospect signals AMG’s willingness to enter the unpredictable high‑end electric market, aiming to attract buyers who demand both performance and zero‑emission technology.

Why the update matters for prospective buyers

For customers considering a high‑performance SUV in the UK, the refreshed GLE 63 and GLS 63 now offer a more powerful V8 without the need to wait for an entirely new generation. The combination of a potent flat‑plane V8, refreshed styling, and the promise of future electric models positions AMG as a brand that balances tradition with innovation. Prospective owners can expect the same practical SUV platform they are familiar with, now coupled with a markedly higher power output.

Conclusion

The mid‑life update of the Mercedes‑AMG GLE 63 and GLS 63 brings a 627 bhp flat‑plane crank V8 to the fore, reinforcing the models’ status as the most powerful SUVs in the AMG line‑up. Coupled with modest design tweaks and the prospect of an electric GT 4‑Door, AMG demonstrates its commitment to keeping the range exciting for performance‑focused buyers, whether they prefer combustion power or are looking ahead to electric performance.
