The 2026 Mercedes-Benz GLS63 4MATIC+ is a high-performance seven-seat luxury SUV that suits affluent buyers wanting serious off-road credentials alongside daily practicality, combining a potent 4-litre twin-turbo petrol engine producing 430kW and 900Nm with mild-hybrid efficiency and a 3500kg towing capacity.
