24 MPG combined requires context when discussing the 2018 Acura TLX AWD 3.5L. This particular TLX configuration isn’t bought for fuel efficiency. Instead, buyers seek the smooth, strong power of the V6, the sure-footedness of all-wheel drive, and the quiet competence that Acura delivers. Fuel economy, for this buyer, is an acceptable compromise, not the main selling point.

City and highway performance

The EPA estimates for the 2018 Acura TLX AWD 3.5L are 21 MPG for city driving and 30 MPG for highway driving. The difference between city and highway indicates the engine’s efficiency when cruising at consistent speeds. Acura’s Variable Cylinder Management (VCM) system plays a role, shutting down cylinders during steady-state highway driving to conserve fuel. In stop-and-go city environments, the engine operates in its six-cylinder mode, resulting in the lower MPG figure. Pay attention to your driving style in urban situations because constant acceleration or idling can severely reduce your city MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Acura TLX AWD 3.5L at $2,400. This is based on driving 15,000 miles per year and using the national average fuel price for regular unleaded gasoline at the time of calculation. Your actual fuel costs will vary depending on mileage, the type of driving you do (city vs. highway), and fluctuations in local fuel prices. However, the $2,400 figure provides a standard for comparing the TLX to other vehicles.

Real-world expectations

The EPA figures provide a baseline, but remember that real-world fuel economy often varies. Aggressive driving, frequent short trips, and extreme weather conditions can negatively impact your MPG. Gentle acceleration, consistent highway speeds, and regular maintenance can help you achieve or exceed the EPA estimates. Owners of the 2018 Acura TLX AWD 3.5L often report average fuel economy in the low-to-mid 20s, matching the official combined rating reasonably well.

How it compares

In the mid-size luxury sedan market with all-wheel drive, the 2018 Acura TLX AWD 3.5L’s fuel economy is competitive, though not the best. The BMW 330i xDrive from the same year gets a combined 28 MPG, a noticeable advantage, but its turbocharged four-cylinder engine provides a different driving experience than the Acura’s V6. The Lexus ES 350, which doesn’t have standard all-wheel drive, delivers around 25 MPG combined in front-wheel drive form. The Audi A4 Quattro is rated at 27 MPG combined. Some drivers might favor Acura’s V6 engine over a turbocharged one, or consider the Acura to be of higher quality and reliability, accepting the lower MPG as a trade-off. Comparing all Acura fuel economy data can also be beneficial.

Tips to maximize efficiency

Use the TLX’s “Econ” mode. This mode adjusts throttle response and transmission shift points to prioritize fuel efficiency. It may slightly reduce acceleration, but it can make a noticeable difference, especially during city driving. It’s a simple way to improve your MPG without drastically changing your driving.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check your tire pressure regularly and keep it at the level on the doorjamb sticker. This can improve fuel economy and handling.

Anticipate traffic flow to avoid unnecessary braking and acceleration. Maintaining a steady speed is more fuel-efficient than constantly speeding up and slowing down. Look ahead and try to maintain a consistent pace. This is helpful in commuting.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Idling uses fuel without moving the vehicle. While the TLX doesn’t have a fully automatic start-stop system, manually turning off the engine in prolonged stops can reduce fuel waste.

Keep up with scheduled maintenance. A well-maintained engine runs more efficiently. Follow the maintenance schedule in your owner’s manual, including oil changes, air filter and spark plug replacements. Regular maintenance will help your engine operate efficiently.
