WLTP Performance and Efficiency

WLTP results vary with wheel size, equipment, aerodynamic specification, temperature, traffic, payload and driving style. The 0.9 kWh battery supports the diesel engine through the mild-hybrid system; it is not intended to provide a conventional plug-in-electric driving range.

Battery & Charging

The battery is charged automatically during driving through energy recuperation and the vehicle’s electrical system. It is not externally chargeable.

SUV Capability

The GLS combines permanent all-wheel-drive traction with electronically controlled suspension height adjustment. AIRMATIC can lower the vehicle for easier loading and raise it when additional underbody clearance is useful on uneven surfaces. Payload and towing limits must be observed together with the vehicle’s permitted axle loads, trailer noseweight and the requirements of the UK driving licence category being used.
