The 2015 Acura TLX 2.4L’s 28 MPG combined rating signals a calculated compromise: efficiency suitable for comfortable daily driving, but without sacrificing the responsive feel expected of an Acura. This isn’t a hybrid chasing ultimate fuel savings, nor is it a hard-edged sports sedan demanding premium gasoline. Rather, it’s a balanced offering catering to those who prioritize a refined driving experience alongside reasonable running costs.

City and highway performance

The EPA estimates provide a clearer picture of the TLX 2.4L’s strengths and weaknesses. Its 24 MPG city rating is adequate for stop-and-go traffic, reflecting the engine’s smooth power delivery and the eight-speed automatic transmission’s ability to select the right gear promptly. Out on the open road, the TLX shines with a 35 MPG highway figure. This makes it a capable and relatively frugal choice for longer commutes or road trips, where the comfortable seats and quiet cabin further enhance the experience. The taller gearing of the 8-speed also settles the engine into its most efficient RPM range at highway speeds.

Annual fuel cost

The EPA estimates that it will cost $2,050 per year to fuel the 2015 Acura TLX 2.4L. This figure is calculated based on driving 15,000 miles per year and using national average fuel prices. This provides buyers with a standardized benchmark for comparing different vehicles. Keep in mind that your personal fuel costs may vary depending on your driving habits, the type of roads you typically drive on, and local fuel prices. Careful monitoring of your own fuel consumption can provide a more personalized estimate.

Real-world expectations

While EPA ratings offer a useful comparison tool, real-world MPG often deviates. Owners of the 2015 TLX 2.4L typically report figures within a few MPG of the EPA estimates, but aggressive driving or primarily city-based commutes can easily drop the average below 24 MPG. Conversely, those who frequently travel on highways and prioritize smooth acceleration may see figures closer to, or even slightly above, the 35 MPG highway rating. Factors like tire pressure, vehicle maintenance, and the use of climate control also play a role.

How it compares

The TLX 2.4L competes in a crowded segment of entry-level luxury sedans. The Lexus IS 300, for example, offers a sportier driving experience but achieves a slightly lower 24 MPG combined. The BMW 320i, while known for its handling, matches the TLX’s 28 MPG combined. Even the closely-related Honda Accord, in top trims with the 2.4L engine, posts similar MPG. These comparisons matter because TLX buyers are often cross-shopping these models, weighing fuel economy against factors like brand image, features, and driving dynamics. For those prioritizing fuel efficiency above all else, a hybrid option like the Lexus ES 300h (44 MPG combined) is worth considering, sacrificing some performance for substantial fuel savings.

Tips to maximize efficiency

Smooth and steady acceleration is key to maximizing fuel economy in the TLX 2.4L. Avoid harsh acceleration from a stop, and anticipate traffic flow to minimize braking. The engine and transmission are calibrated for efficiency under moderate loads, so driving with a light foot will make a noticeable difference over time.

Regular maintenance, including timely oil changes and air filter replacements, ensures that the engine operates at peak efficiency. A clean air filter allows for optimal airflow, while fresh oil reduces friction within the engine. These seemingly small details can collectively improve fuel economy by a measurable margin.

Tire pressure significantly impacts rolling resistance. Check your tire pressure regularly and maintain it at the recommended level, which can be found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, leading to lower MPG. Overinflated tires reduce comfort and grip.

Minimize idling time whenever possible. If you anticipate being stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling consumes fuel without any forward progress. This is especially true with the TLX 2.4L since it does not have a stop/start system.

Consider using the car’s “Econ” mode, if equipped. This setting adjusts throttle response and transmission behavior to prioritize fuel efficiency over performance. While it may slightly reduce acceleration, it can help to consistently achieve higher MPG, especially in city driving.
