25 MPG combined is an acceptable fuel economy figure for the 2015 Acura TLX 3.5L, especially considering it’s designed to be a comfortable, well-equipped sedan with a smooth V6 engine. It offers a balance of performance and reasonable running costs. The buyer likely values a refined driving experience and a touch of luxury without the aggressive demeanor of a BMW or Lexus, and accepts mid-pack fuel economy.

City and highway performance

The EPA estimates for the 2015 Acura TLX 3.5L are 21 MPG in the city and 34 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine works harder. However, the highway number shows the benefits of the TLX’s nine-speed automatic transmission (S9), which allows the engine to cruise at relatively low RPMs, maximizing efficiency on longer drives. The highway fuel economy often sways buyers; they know they can achieve a respectable figure on their daily commute or weekend getaways.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Acura TLX 3.5L at $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. Individual costs will vary based on driving habits, location, and prevailing gas prices, but this provides a benchmark for comparing the TLX’s running costs against other vehicles. Consider this number with overall vehicle ownership costs like insurance, maintenance, and depreciation. Fuel is just one factor.

Real-world expectations

While the EPA numbers offer a comparison point, real-world fuel economy varies. Owners of the 2015 TLX 3.5L report numbers close to the EPA estimates, particularly on the highway. Aggressive driving, frequent short trips, and heavy city traffic can reduce fuel economy. The car’s trip computer provides real-time and average MPG readouts, which can help drivers monitor fuel consumption and adjust driving habits. Premium fuel is recommended for optimal performance, which can slightly increase the cost per gallon.

How it compares

The 2015 Acura TLX 3.5L isn’t the most fuel efficient, but it’s competitive. A 2015 Lexus ES 350 achieves 24 MPG combined, 21 MPG city, and 31 MPG highway. The V6-powered 2015 Toyota Avalon gets 21 MPG city and 31 MPG highway. A 2015 Audi A4 2.0T with front-wheel drive achieves 25 MPG city and 33 MPG highway but lacks the V6 power. These comparisons show the TLX’s balance of performance and efficiency, appealing to buyers who want a comfortable driving experience over fuel savings.

Tips to maximize efficiency

Avoid aggressive acceleration and hard braking. The TLX’s V6 responds well to a smooth driving style. Gentle acceleration and anticipating traffic to minimize braking will affect your fuel consumption.

Monitor your tire pressure. Underinflated tires increase rolling resistance, reducing fuel economy. Check your tire pressure monthly, matching the recommended pressure on the driver’s side doorjamb.

Use cruise control on the highway. Maintaining a consistent speed reduces unnecessary acceleration, improving fuel economy. The TLX’s adaptive cruise control helps maintain a safe following distance.

Minimize idling. If you’re stopped longer than a minute, turn off the engine. Modern cars restart quickly, and avoiding idling saves fuel.

Consider the weight you are carrying by removing unnecessary items from the trunk. Extra weight reduces fuel economy, particularly in city driving.
