AMG's V8 Refuses To Quiet Down: New GLE 63 S And GLS 63 Sharpen The High-Performance SUV Game
SHERIDAN, WYOMING – June 17, 2026 – Mercedes-AMG has rolled out the extensively updated 2027 AMG GLE 63 S and AMG GLS 63, a pair of high-performance SUVs built around a thoroughly reworked 4.0-liter V8 biturbo engine now churning out 603 hp and 627 lb-ft of torque. Both models land at U.S. dealerships this fall, giving American buyers their first real crack at AMG's latest spin on eight-cylinder muscle stuffed into a daily-usable SUV body. For anyone who's followed AMG's V8 story over the years, this update matters because it proves the engine isn't fading quietly into an electrified future — it's adapting, loudly. New tech like the ISG 2.0 mild-hybrid system and AMG ACTIVE RIDE CONTROL hint that AMG still believes performance and comfort don't have to cancel each other out.
