Mercedes AMG5 3 reveiw 2026 001Mercedes AMG5 3 reveiw 2026 001IntroductionAMG is quietly changing direction with this new Mercedes-AMG GLC 53.Three years after launching the technically ambitious but commercially divisive four-cylinder GLC 63 S E-Performance, it has stepped back from the highly complex plug-in hybrid formula used by that car in favour of something that feels far more natural for a fast mid-sized SUV: six cylinders, less complication and a much sharper focus on drivability. In the process, Affalterbach has fundamentally reshaped its GLC line-up.AdvertisementAdvertisementThe previous four-cylinder GLC 43 and PHEV GLC 63 have disappeared, replaced by a single six-cylinder GLC 53 conceived to balance genuine performance with everyday usability. The move mirrors changes already seen with the CLE 53 Coupé and Cabriolet, where AMG has begun moving away from heavily electrified four-cylinder powertrains in favour of larger-capacity six-cylinder engines with a more traditional character. In the GLC 53, the approach feels particularly well suited.The first-generation GLC 63 used a turbocharged 4.0-litre V8 – still one of the defining engines of the modern AMG era. After the mixed reception for its four-cylinder PHEV replacement, the new GLC 53 feels much closer in spirit to that original model, even if the emphasis has shifted slightly away from outright aggression towards a more rounded and mature character.Design & stylingMercedes AMG5 3 reveiw 2026 002Visually, the changes are restrained by AMG standards but suit the GLC well. The Panamericana grille immediately separates it from lesser models, while the deeper front bumper, larger air intakes and reshaped lower surfaces give it a noticeably more purposeful stance.Broader front tracks and subtly reshaped wheel arches add extra visual width, while the rear receives a more prominent diffuser, quad exhaust outlets and a discreet roof-mounted spoiler. Standard 21in wheels fill the arches convincingly without tipping into the sort of visual excess that AMG has occasionally struggled with in recent years. Buyers can still choose between traditional SUV and sleeker Coupé bodystyles; I have the former here.InteriorMercedes AMG5 3 reveiw 2026 003Inside, the GLC 53 follows the established Mercedes-Benz SUV formula, albeit with a noticeably sportier edge. Material quality is excellent throughout, while sports seats, microfibre trim and AMG-specific graphics for the digital instruments and touchscreen help give the cabin a more focused feel.AdvertisementAdvertisementMercedes' MBUX infotainment system remains visually impressive and highly configurable in its latest generation, although the continued reliance on touchscreen controls can still frustrate on the move. The driving position, meanwhile, strikes a convincing balance between SUV visibility and genuine sporting intent.Engines & performanceMercedes AMG5 3 reveiw 2026 014AMG's biggest changes have been made beneath the bodywork, however. In place of that divisive four-cylinder PHEV powertrain sits AMG's turbocharged 3.0-litre straight six, paired with a 48V integrated starter-generator providing mild-hybrid assistance and a nine-speed automatic gearbox driving all four wheels through AMG's fully variable 4Matic+ four-wheel drive system.The engine develops 449bhp between 5500rpm and 6100rpm and 442lb ft from 2200–5000rpm, with overboost briefly raising torque to 472lb ft. AMG claims 0–62mph in 4.2sec and a top speed electronically limited to 155mph, or 168mph with the optional AMG Driver's Package (which is bundled into the £7500 Pro Performance Package in the UK).More important than the numbers themselves, however, is the way the new drivetrain changes the character of the GLC. The straight six here restores the smoothness, flexibility and progressive power delivery that had been missing from the old four-cylinder PHEV, which often felt oddly artificial. It responds crisply at lower speeds, spins cleanly through the rev range and delivers its performance with genuine enthusiasm.AdvertisementAdvertisementThere's plenty of pace: the GLC 53 feels quick in almost any situation, with strong initial response, muscular mid-range performance and enough top-end urgency to make sustained acceleration genuinely entertaining. And crucially it feels fast without becoming intimidating.Ride & handlingMercedes AMG5 3 reveiw 2026 015AMG has also extensively revised the standard Mercedes GLC’s chassis. The GLC 53 receives adaptive Ride Control suspension with steel springs, variable damping control and rear-wheel steering as standard. An electronically controlled rear differential is additionally available through the optional AMG Dynamic Plus Package (another constituent of that £7500 bundle in the UK). The front end turns in keenly and the rear-wheel steering system gives the GLC 53 a noticeably more agile feel than its size (4.7m long by 1.9m wide) initially suggests.Direction changes are clean and predictable, while the 4Matic+ system provides impressive traction when you're accelerating hard out of slower corners. What stands out most, however, is how composed the GLC 53 feels when pushed hard. The body remains tightly controlled and the chassis feels disciplined and secure, although the ride remains firmly on the sporting side of acceptable.Even in Comfort driving mode there's a constant underlying firmness that never entirely disappears. AMG has clearly prioritised body control, steering precision and high-speed stability over outright suppleness, and on rougher roads the suspension can occasionally feel busy on those big, 21in wheels. The payoff comes when the pace rises. On smoother roads the GLC 53 delivers excellent damping control and very little unwanted body movement during quick direction changes or heavy braking.VerdictMercedes AMG5 3 reveiw 2026 017Where the old four-cylinder PHEV sometimes felt engineered around a powertrain concept first and a driving experience second, this car feels far more cohesive.AdvertisementAdvertisementIt may lack the wild character of the original V8-powered GLC 63 but, as an everyday performance SUV, this is arguably AMG's best GLC-based model yet.]]>
