The 2024 Lexus TX 500h AWD gets 27 MPG combined, a respectable figure for a vehicle of this type. The goal isn’t just maximum fuel economy; it’s about providing acceptable efficiency in a spacious, luxurious, and technologically advanced three-row SUV with engaging performance. The TX 500h buyer wants a premium experience for the entire family and values a refined ride, modern features, and a touch of sportiness over squeezing every last mile from a gallon.

City and highway performance

The EPA estimates the TX 500h AWD at 27 MPG in the city and 28 MPG on the highway. These figures are closely aligned, reflecting the hybrid powertrain’s ability to use regenerative braking and electric assist effectively in both driving environments. The small difference between city and highway MPG suggests the TX 500h maintains consistent efficiency regardless of traffic conditions. This consistency is a positive attribute for families who split their time between daily commutes and longer road trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Lexus TX 500h AWD at $2,150. This is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful comparison point with other vehicles in its class, but individual fuel costs will vary based on driving habits, local fuel prices, and driving type (primarily city or highway).

Real-world expectations

While the EPA estimates offer a standardized comparison, real-world fuel economy always varies. If you drive conservatively and maximize the hybrid system’s capabilities, expect to see numbers close to the EPA figures. However, aggressive acceleration, frequent use of the sport drive modes, and consistent highway speeds above 70 mph will likely result in lower MPG. Understand how your driving style impacts efficiency to manage your refueling expectations.

How it compares

The TX 500h’s fuel economy is competitive within the three-row luxury SUV segment. The Acura MDX, with its standard V6 engine, achieves around 22 MPG combined. The Volvo XC90 Recharge plug-in hybrid offers significantly better efficiency when using its electric range, but its combined MPG drops to around 27 MPG when running solely on gasoline. A comparable BMW X5 xDrive40i gets around 25 MPG combined. Buyers choose the TX 500h because it offers better fuel economy than its non-hybrid rivals, without the charging complexities of a plug-in hybrid.

Tips to maximize efficiency

Drive smoothly and avoid abrupt acceleration or braking. The TX 500h’s hybrid system is most efficient when operated with a gentle touch. Minimize hard acceleration to maximize battery usage and fuel efficiency. Watch the energy monitor display to understand how the hybrid system operates and adjust your driving accordingly.

Use the “Normal” or “Eco” drive modes for everyday driving. These modes optimize the powertrain for fuel efficiency by smoothing throttle response and adjusting the climate control system. Sportier modes will lead to more aggressive engine mapping, reducing MPG.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels specified on the doorjamb sticker. A few PSI can make a surprising difference over time.

Reduce unnecessary weight. Remove any items from the vehicle that you don’t need. Extra weight increases the engine’s workload and reduces fuel efficiency. Consider removing roof racks or cargo carriers when not in use, as they create aerodynamic drag.

Plan your routes strategically to avoid stop-and-go traffic as much as possible. Consistent highway speeds or steady city driving allows the hybrid system to operate more efficiently than constantly accelerating and decelerating.
