25 MPG combined is a reasonable figure for the 2017 Acura TLX FWD 3.5L, especially considering its purpose. This isn’t supposed to be a hyper-efficient appliance; it’s a comfortable and refined sedan with a healthy dose of V6 power under the hood, built for the professional who wants a touch of excitement in their daily commute. Someone buys this car because they want a smooth, quiet ride, good acceleration, and the Acura badge. Fuel economy, while important, isn’t the primary reason behind this purchase.

City and highway performance

The EPA estimates 21 MPG in the city and 34 MPG on the highway for this specific TLX configuration. These numbers reflect the car’s tuning. The V6 delivers ample power for confident merging and passing, which inevitably impacts city fuel consumption. However, on the open road, the 9-speed automatic transmission (S9) helps the engine settle into a relaxed cruise, maximizing efficiency. The 34 MPG highway figure is achievable if you resist the urge to frequently dip into that readily available V6 power.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2017 Acura TLX FWD 3.5L is approximately $2,300. This estimate is based on driving 15,000 miles per year and using the national average fuel price. Your actual fuel costs may vary depending on your driving habits, local fuel prices, and the type of fuel you use. Premium fuel is recommended for optimal performance, and prices fluctuate daily. The $2,300 estimate provides a useful benchmark, but it’s essential to factor in your personal driving circumstances.

Real-world expectations

While the EPA estimates are useful, real-world MPG often differs. An experienced TLX driver will likely see figures close to the EPA estimates with mindful driving. Expect around 19-23 MPG in typical city driving and 31-36 MPG on the highway during longer trips. Aggressive acceleration, frequent short trips, and heavy traffic will push the numbers lower. Consistent use of the car’s ECON mode can slightly improve efficiency, but it also dulls throttle response. Choosing Sport mode will prioritize performance over saving fuel. Factors like tire pressure, vehicle maintenance, and even the weather conditions influence the actual MPG you achieve.

How it compares

The 2017 Acura TLX FWD 3.5L occupies a competitive space in the mid-size luxury sedan market. Consider the Lexus ES 350 from the same year, which delivers similar performance and luxury but boasts an EPA combined rating of 24 MPG, slightly lower than the TLX. The BMW 330i, while dynamically superior, only manages around 28 MPG combined. The Audi A4, with its smaller turbocharged engine, achieves a better combined rating. Drivers choosing the TLX likely prioritize V6 smoothness and Acura’s reputation for reliability over ultimate fuel efficiency. For a broader picture, you can find TLX MPG across all years on this site.

Tips to maximize efficiency

Use cruise control on the highway. The TLX’s adaptive cruise control is especially helpful for maintaining a consistent speed, which directly translates to improved fuel economy. Avoiding sudden acceleration and braking can dramatically impact your gas mileage on long highway drives.

Monitor and maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and use more fuel. Refer to the sticker on the driver’s side doorjamb for the recommended tire pressure.

Minimize idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you’re stopped for more than a minute or two, turn off the engine. While some newer cars have auto start-stop features, this model does not, so it’s important to be proactive.

Service your vehicle regularly. Routine maintenance, such as oil changes and air filter replacements, ensures the engine is running efficiently. A well-maintained engine consumes less fuel and lasts longer. Regular maintenance also helps to keep the advanced 9-speed transmission operating smoothly, which helps with maximizing efficiency.

Avoid carrying unnecessary weight. Extra cargo in the trunk or backseat adds weight to the vehicle, reducing fuel economy. Remove any items you don’t need to lighten the load.
