With the introduction of the new GLC 53, Mercedes-AMG has made a strong comeback for Affalterbach’s performance SUV.
Out goes the divisive four-cylinder setup, replaced by a comprehensively reworked 3.0-litre turbocharged straight-six, restoring the soundtrack, character and punch many enthusiasts felt had been missing.
The revised six-cylinder unit has been heavily upgraded, featuring a new cylinder head, reworked intake and exhaust ports, a larger intake system and an uprated intercooler.
Boost pressure now peaks at 1.5 bar, while the electric compressor can operate for longer periods to sharpen throttle response.
The result is 443bhp and 443lb ft, rising to 472lb ft on overboost, sent through AMG’s nine-speed Speedshift automatic gearbox and fully variable all-wheel drive.
Performance figures are suitably serious, with 0–62mph in 4.2 seconds and a limited 155mph top speed.
AMG has also focused on driver engagement. The GLC 53 can fully decouple the front axle to run in rear-wheel drive, while a rear electronic limited-slip differential and rear-axle steering appear for the first time.
A starter-generator integrated into the transmission supports stop-start operation and delivers brief additional boost when needed.
Braking hardware is equally substantial, with 390mm front discs and four-piston calipers, backed up by 360mm rear discs.
Sound, AMG insists, is a major part of the experience. A new exhaust system promises a louder, more emotional note, complete with crackles on lift-off and a deep, bass-heavy growl under load.
Early buyers can specify a Golden Accents pack, while the Night Package adds gloss black detailing throughout.
According to AMG boss Michael Schiebe, the aim was clear: more emotion, more character, and more fun. On paper, the GLC 53 finally delivers.
