AMG Unleashes V8 Power: GLS & GLE Get Major Upgrades

Mercedes-AMG has globally revealed updated versions of its GLS 63 and GLE 63 S SUVs, bringing substantial mechanical and chassis enhancements. The most notable update is the revised 4.0-litre twin-turbocharged M177 EVO V8 engine. This powertrain now incorporates a flat-plane crankshaft, a technology inspired by motorsport, which reduces rotational mass and sharpens throttle response.

Both performance SUVs are equipped with a 48V mild-hybrid system that contributes an additional 23 hp during acceleration and also boosts fuel efficiency. The engine benefits from revised fuel injection, intake and exhaust ports, camshafts, and turbocharger housing. Despite efficiency improvements, the vehicles maintain formidable performance figures. The GLE 63 S achieves 0-100 kmph in 3.9 seconds, while the larger GLS 63 does it in 4.2 seconds. Both models feature AMG's all-wheel-drive system and can reach top speeds of up to 280 kmph.

Further enhancing their dynamic capabilities, the updated models receive an improved active ride control system to mitigate body roll. AMG has also strengthened the driveshafts to handle the increased power. The GLS 63 additionally features a rear-axle locking differential for enhanced traction. An adaptive exhaust system further refines the driving experience by adjusting sound characteristics.
