Here are the 2026 Audi e-tron GT city/highway efficiency and range details you asked about — based on the most recent EPA estimates and available specs:

⚡ Fuel Economy (EPA MPGe)

• City: ~91 MPGe

• Highway: ~88 MPGe

• Combined: ~90 MPGe
  These figures come from EPA estimates for the updated e-tron GT (including the S model); final 2026 EPA values aren’t published yet but are expected to be very similar to the latest numbers. 

🚗 Electric Range

• EPA-Estimated Range: ~278 – 300 miles
  This is the approximate EPA range for the refreshed models on a full charge, depending on wheel size and conditions. 

🔋 Battery & Charging

• Battery Pack: ~105 kWh total (≈97 kWh usable)

• DC Fast Charging: ~320 kW peak — approx. 10 % → 80 % in ~18 minutes on a high-power DC fast charger. 

🚙 What This Means

• The MPGe numbers (MPGe = Miles Per Gallon Equivalent) give you a good idea of efficiency — higher is more efficient when compared to other EVs in city or highway driving. 

• A ~300-mile EPA range makes the e-tron GT competitive in the premium electric sedan segment, suitable for most daily use and many longer trips with fast charging stops.
