2026 Lexus LC 500 Convertible — the open‑top version of Lexus’s luxury grand tourer powered by a naturally aspirated V‑8 engine:

🔥 2026 Lexus LC 500 Convertible – EPA MPG (City / Highway)

• City: 15 MPG

• Highway: 25 MPG

• Combined: ~18 MPG
  (This is the EPA estimate for the 5.0 L V‑8 rear‑wheel‑drive convertible.)

🧠 Engine & Basics

• Engine: 5.0 L naturally aspirated V‑8 (~471 hp / 398 lb‑ft) — same powerplant as the coupe. 

• Transmission: 10‑speed automatic

• Drivetrain: Rear‑wheel drive 

• Fuel: Premium unleaded gasoline required 

📌 What This Means

• City MPG (15): Lower in urban stop‑and‑go traffic, typical for a high‑performance V‑8 convertible. 

• Highway MPG (25): Better fuel economy at steady speeds on open roads. 

• Combined (~18): Overall average economy reflecting mixed driving. 

The convertible typically rates slightly lower in city and slightly higher on highway compared with the coupe because of weight and aerodynamics changes. Real‑world testers note similar figures and sometimes see improved highway results under ideal conditions.
