What is the real-world range of the 2025 Mercedes-Benz EQS in Canadian winter conditions?
The 2025 EQS declares an EPA range of 660 km (EQS 450+, RWD, 107.8 kWh battery) and 601 km (EQS 580 4MATIC, AWD). In typical Canadian winter conditions (-15°C, highway at 100 km/h), real-world range drops to approximately 380-420 km for the EQS 450+ and 340-380 km for the EQS 580 4MATIC — a 35-40% reduction due to cabin heating demands and reduced battery chemistry efficiency in cold. The standard heat pump (included on all Canadian-spec 2025 EQS models) recovers thermal energy from drivetrain components to reduce heating impact by 8-12% compared to direct electric heating. DC fast charging up to 200 kW (EQS 580) recovers 200 km of range in 15 minutes at IONITY or BRAVIA stations across Canada.
