Mercedes-AMG reveals the 2027 GLS63, its most powerful three-row luxury SUV to date. The performance variant of the GLS-Class flagship arrives with a twin-turbocharged 4.0-liter V8 engine paired with an integrated electric motor, producing over 600 horsepower. The hybrid system elevates the GLS63 into direct competition with BMW's X7 M50i xDrive and the Porsche Cayenne Turbo S E-Hybrid.
The 2027 GLS63 adopts Mercedes-AMG's latest design language, featuring an aggressive front grille, wider stance, and angular LED headlight clusters that establish immediate visual separation from standard GLS models. The SUV retains the three-row seating layout while adding muscular body kit elements including flared fenders, a prominent roof spoiler, and darkened trim pieces throughout. Twenty-inch wheels come standard, with larger options available.
Inside, the GLS63 receives AMG-specific treatments: performance seats with aggressive bolstering, a flat-bottomed steering wheel, and upgraded trim materials. The dual-screen infotainment system integrates Mercedes-Benz's latest MBUX software, offering navigation, connectivity, and vehicle performance readouts tailored to AMG models.
Performance expectations point toward sub-4-second 0-60 times and a top speed electronically limited to 130 mph. The hybrid system adds low-end torque response while the electric motor assists acceleration during high-load scenarios. Four-wheel drive and adaptive air suspension come standard, allowing drivers to adjust ride height and damping for either comfort or aggressive cornering.
Pricing for the 2027 GLS63 starts around $110,000, placing it above the standard GLS580 but below ultra-luxury
