27 MPG combined is a respectable figure for the 2018 Acura TLX FWD 2.4L 4-cyl, a car that consistently delivers a balance of sporty handling, premium features, and everyday usability. This isn’t a hybrid chasing maximum efficiency, nor is it a V6-powered bruiser prioritizing raw power. Instead, the TLX 2.4 is for buyers who prioritize a well-rounded driving experience with decent fuel consumption, people willing to trade a few MPG for the TLX’s smooth ride quality and Acura’s reputation for reliability.

City and highway performance

The EPA estimates the 2018 Acura TLX 2.4L FWD will achieve 23 MPG in the city and 33 MPG on the highway. The city figure reflects stop-and-go traffic, where the 2.4L engine and 8-speed dual-clutch transmission provide smooth acceleration and responsive shifts. On the highway, the 33 MPG rating is achievable during steady-state cruising, thanks to the transmission’s ability to select optimal gears for maximizing fuel efficiency at higher speeds.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2018 Acura TLX 2.4L FWD is $2,150. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, local fuel prices, and the specific conditions in which you operate the vehicle. This is a benchmark to help you consider the total cost of owning a TLX, including the amount you’ll spend on gas.

Real-world expectations

While the EPA provides a standardized measure, real-world fuel economy often differs. Aggressive driving, frequent short trips, and prolonged idling will negatively impact fuel consumption. Careful driving, consistent highway speeds, and proper vehicle maintenance can help you achieve numbers closer to the EPA estimates, or even slightly exceed them. The TLX’s Multi-Information Display provides real-time fuel economy data, helping drivers adopt more efficient habits.

How it compares

In the mid-size sedan segment, the 2018 Acura TLX 2.4L FWD holds its own in terms of fuel economy. Consider the Lexus ES 350, a similarly positioned luxury sedan, which achieves a combined 26 MPG with its V6 engine. A base BMW 330i from the same year, with its turbocharged 2.0L engine, manages a slightly better 28 MPG combined. The difference of a single MPG means something to a thrifty buyer, but someone who is looking at all Acura fuel economy data may prioritize the TLX’s blend of performance, features, and value over the absolute highest MPG. For buyers considering other TLX MPG across all years, knowing the specific engine options is important for comparisons between model years.

Tips to maximize efficiency

Smooth and steady acceleration is key. The TLX’s 8-speed dual-clutch transmission responds best to gradual throttle inputs. Avoid sudden bursts of acceleration and hard braking; these actions consume more fuel. Think ahead and anticipate traffic flow.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels specified on the sticker located on the driver’s side doorjamb. This simple step can noticeably improve your fuel efficiency.

Reduce unnecessary weight. Carrying extra cargo in your trunk adds weight to the vehicle, forcing the engine to work harder and burn more fuel. Remove any unnecessary items from your trunk to lighten the load and improve fuel economy, for example sports equipment, tools, or bulky items that are not needed for daily driving.

Use cruise control on the highway. Maintaining a consistent speed helps optimize fuel efficiency. Use cruise control on long stretches of highway to avoid unintentional speed fluctuations and maintain a steady pace, maximizing your MPG. Remember to disengage cruise control in inclement weather or heavy traffic.
