2026 Mercedes‑Benz EQE 320 Sedan (electric luxury sedan): 

⚡ EPA Efficiency — MPGe (electric)

• City: ~87 MPGe (EPA estimated) 

• Highway: ~85 MPGe (EPA estimated) 

• Combined: ~86 MPGe (EPA estimated) 

MPGe (miles per gallon equivalent) expresses how efficiently the EQE uses electricity compared to a gasoline‑powered car. A higher number means better efficiency. 

🔋 EPA Estimated Range

• EPA electric range: ~267 miles on a full charge for the AWD EQE 320 4MATIC sedan. 

This range figure comes from Mercedes’ official data for the EQE 320 model with a ~90.6 kWh usable battery pack; RWD versions (like the EQE 320+) may have a slightly higher rated range (~308 miles) with a larger pack. 

🚗 What City vs Highway Means for You

City Driving

• EVs generally perform more efficiently in stop‑and‑go conditions because regenerative braking recaptures some energy.

• The EQE’s ~87 MPGe city rating reflects this benefit. 

Highway Driving

• At steady faster speeds, energy use increases from wind resistance.

• Still, the EQE remains efficient with ~85 MPGe highway. 

So while you’ll see slightly better efficiency in urban conditions compared with highway cruising, the difference is relatively small — thanks to the EQE’s aerodynamic design and electric drivetrain.
