2026 Lexus LS 500 luxury sedan (the AWD Heritage Edition is the sole U.S. model for 2026):

🛻 2026 Lexus LS 500 – EPA City / Highway MPG

• City: 17 MPG

• Highway: 27 MPG

• Combined: 21 MPG

🔎 Powertrain & Details

• Engine: 3.4 L twin-turbo V-6 (~416 hp, 442 lb-ft) 

• Transmission: 10-speed automatic 

• Drivetrain: Standard All-Wheel Drive (AWD)

• Fuel: Premium unleaded recommended 

These ratings reflect the EPA’s performance estimates for real-world driving and are consistent across sources. They indicate typical efficiency for a large, powerful AWD luxury sedan: lower city MPG due to heavier vehicle weight and less frequent highway cruising, and better highway MPG at steady speeds. 

🚗 What It Means

• City driving (~17 MPG): Typical for a flagship sedan with a high-output turbocharged engine. 

• Highway driving (~27 MPG): Improved economy under steady cruising conditions. 

• Range: With a ~21.7-gallon tank, the LS 500 can cover substantial distances between fill-ups (often 400+ miles) in mixed driving. 

If you’d like, I can estimate real-world range based on these ratings or compare the LS 500’s fuel economy with rival full-size luxury sedans like the BMW 7 Series or Mercedes-Benz S-Class.
