🔋 EPA Efficiency — City / Highway

2026 Mercedes‑Benz EQS 450 4MATIC (AWD EV sedan)

• City MPGe: ~91 MPGe

• Highway MPGe: ~93 MPGe

• Combined MPGe: ~92 MPGe (est.)

• EPA Estimated Range: ~367 miles per charge

These are the EPA metrics indicating how efficiently the EV uses energy in city and highway conditions compared to gasoline vehicles.

🚗 What City vs Highway Means

• City driving: Around 91 MPGe — EVs benefit from regenerative braking in stop‑and‑go traffic, boosting urban efficiency. 

• Highway driving: Around 93 MPGe — a slight efficiency increase at sustained higher speeds thanks to optimized aerodynamics and balance of motor output. 

• Real‑world range: The EPA ~367 mile rating gives a good benchmark for mixed driving, though actual range on long highway trips may dip slightly and urban usage may stretch toward or above EPA claims depending on conditions and driving style. 

The EQS 450’s efficiency is competitive with other luxury EVs of similar size — large, aerodynamic, and trimmed for comfortable long‑distance travel without extreme energy use.
