23 MPG combined isn’t going to win any awards in the midsize SUV segment, but the 2024 Lexus TX 350 AWD 2.4L 4-cyl is designed for a specific buyer: someone who prioritizes a plush ride, a vault-like interior, and the reassurance of a premium badge over outright fuel efficiency. This isn’t a vehicle chasing Prius owners; it’s quietly doing its job shuttling families and their cargo while maintaining Lexus’s reputation for comfort and dependability.

City and highway performance

The EPA estimates reflect the TX’s performance in varying conditions: 20 MPG in the city and 26 MPG on the highway. The city figure hints at the impact of the TX’s weight and the stop-and-go driving that naturally reduces fuel economy. The highway rating, however, shows the potential of the turbocharged 2.4L engine to deliver more respectable numbers when cruising at a steady speed. The eight-speed automatic transmission plays a role here, keeping the engine in its most efficient range. Drivers who frequently engage the All-Wheel Drive system, especially in adverse weather conditions, may observe a dip in both city and highway figures.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2024 Lexus TX 350 AWD 2.4L 4-cyl to be $2,500. This figure is based on driving 15,000 miles per year and using the national average fuel prices at the time of calculation. Individual fuel costs will vary depending on driving habits, local fuel prices, and the type of fuel used. While this is a useful benchmark, understand that aggressive driving or consistently using premium fuel will undoubtedly increase your personal fuel expenditure beyond the EPA’s estimate. Remember that fluctuations in gas prices can significantly alter this annual cost.

Real-world expectations

While the EPA provides a standardized estimate, real-world MPG often differs. Drivers who spend more time in dense urban environments with frequent idling and low speeds are likely to see numbers closer to or even below the 20 MPG city rating. Conversely, those who primarily use the TX for longer highway journeys, sticking to posted speed limits, might experience figures closer to or slightly above the 26 MPG highway estimate. The key is understanding your own driving patterns and how they align with the conditions used for EPA testing. Regular maintenance, including tire inflation, can also positively influence real-world fuel economy.

How it compares

The Lexus TX inhabits a competitive segment. The Acura MDX SH-AWD, a perennial favorite, manages around 21 MPG combined. The Infiniti QX60, another popular choice with a focus on comfort, lands around 23 MPG combined in its AWD configuration. The Volvo XC90 B6 AWD sits closer to 22 MPG combined. These comparisons are vital for the Lexus TX buyer. While all offer three-row seating and a luxurious experience, subtle differences in fuel economy, combined with varying levels of performance and features, can sway a decision. For example, someone prioritizing cargo space over absolute fuel efficiency might be willing to accept the TX’s MPG, while another buyer might lean towards the Acura MDX for its slightly sportier driving dynamics and comparable mileage.

Tips to maximize efficiency

Anticipate traffic flow to minimize braking and acceleration. The TX’s eight-speed transmission benefits from smooth, gradual inputs. Avoid sudden bursts of speed, as the turbocharger will kick in more aggressively, consuming more fuel.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly and maintain the recommended PSI, found on the driver’s side door jamb.

Reduce unnecessary weight. Carrying extra cargo in the vehicle adds to the load the engine must haul, decreasing fuel efficiency. Remove items you don’t need, especially heavier objects that can significantly impact MPG. See TX MPG across all years.

Use cruise control on the highway. Maintaining a consistent speed helps optimize fuel consumption. However, be mindful of terrain changes and avoid using cruise control in hilly areas, as the transmission may downshift frequently.

Consider using the “Eco” drive mode, if equipped. This mode typically adjusts throttle response and shift points to prioritize fuel efficiency. It may slightly reduce performance, but can contribute to improved MPG on longer drives; You can find all all Lexus fuel economy data.
