25 MPG combined is a respectable figure for the 2025 Acura TLX FWD 2.0L 4-cyl. It’s not a hybrid or a stripped-down economy car; it’s a stylish, comfortable entry-level luxury sedan for younger professionals who value a premium driving experience but aren’t necessarily chasing ultimate performance. Fuel economy is a consideration, balanced against the car’s design, features, and prestige. The TLX buyer wants a level of engineering beyond a mainstream sedan, and 25 MPG is the compromise they’re willing to make.

City and highway performance

The EPA estimates the 2025 Acura TLX FWD 2.0L 4-cyl at 22 MPG in the city and 31 MPG on the highway. The city rating reflects stop-and-go traffic and lower average speeds, where the engine spends more time at lower efficiency levels. The highway rating demonstrates the engine’s improved efficiency during steady-state cruising. While 31 MPG on the highway is decent, aggressive driving or strong headwinds can significantly reduce that number. Drivers who frequently encounter heavy urban congestion will likely see results closer to the city estimate, while those with longer commutes on open highways may find themselves exceeding the official highway rating. The 10-speed automatic transmission makes good use of the engine’s powerband and also contributes to highway efficiency by keeping the RPMs low at higher speeds.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2025 Acura TLX FWD 2.0L 4-cyl will be $2,300. The EPA calculates this figure based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, and using the national average fuel price. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use (premium is recommended for this TLX’s engine), and the price of gasoline in your specific area. If you drive significantly more or less than 15,000 miles annually, you can adjust this figure accordingly to get a more personalized estimate of your potential fuel expenses. Review all Acura fuel economy data to analyze the entire brand’s performance.

Real-world expectations

Official EPA estimates offer a standardized baseline, but real-world fuel economy often differs. Achieving the stated 25 MPG combined figure will depend on your driving style. Expect to see lower numbers if you drive aggressively, frequently use the Sport mode, or spend a lot of time idling in traffic. But, if you prioritize smooth acceleration, maintain consistent speeds, and anticipate traffic flow, you’ll likely come closer to, or slightly exceed, the EPA estimates. The TLX’s onboard computer provides real-time and average fuel economy readings, helping drivers monitor their efficiency and make adjustments to their driving habits.

How it compares

The 2025 Acura TLX FWD 2.0L 4-cyl falls roughly in the middle of its competitors for fuel economy. The BMW 330i, another popular choice in the entry-level luxury sedan segment, achieves an EPA-estimated 29 MPG combined. The Lexus IS 300 RWD is rated at 25 MPG combined, matching the TLX, while the Genesis G70 2.0T RWD comes in at 24 MPG combined. Considering that the TLX emphasizes interior refinement and a balance of sporty handling and relaxed comfort, these differences in fuel economy are a factor for car buyers. Buyers might be drawn to a particular aesthetic, for example, or some may have a preference for Acura’s interior design or its reputation for reliability, which may sway them away from a 330i. Review TLX MPG across all years to get a better understanding of its efficiency.

Tips to maximize efficiency

Gentle acceleration is essential for less gas. Avoid stomping on the gas pedal, which forces the engine to work harder and burn more fuel. Instead, gradually increase your speed to minimize fuel consumption.

Maintain a steady speed whenever possible. Using cruise control on the highway can help you maintain consistent speeds and avoid unnecessary acceleration and deceleration, which can improve fuel economy.

Proper tire inflation is critical. Underinflated tires create more rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressure regularly and inflate them to the manufacturer’s recommended levels, found on the driver’s side doorjamb.

Reduce unnecessary weight in the vehicle because carrying extra weight in your trunk or back seat can negatively impact fuel economy. Remove any items you don’t need to lighten the load and improve your MPG.

Be mindful of driving in Sport mode. While Sport mode enhances throttle response and steering feel, it also holds gears longer and uses more fuel. Use it carefully and switch to normal or eco mode when cruising on the highway or driving in the city to maximize fuel efficiency.
