23 MPG combined won’t win any awards for less gas, but it defines the 2019 Acura TLX FWD A-SPEC 3.5L perfectly: a stylish, comfortably sporty sedan that prioritizes driving enjoyment over outright fuel efficiency. While hybrid competitors might have better numbers, the TLX A-SPEC appeals to a buyer who values a naturally aspirated V6 engine and sharp handling more than saving every last mile from a gallon of premium fuel. This is for someone who savors the journey, not just the cost of it.

City and highway performance

The EPA estimates of 20 MPG in the city and 30 MPG on the highway reflect the TLX A-SPEC’s dual nature. The 20 MPG city figure is adequate but uninspiring, a result of the 3.5L V6 needing to work harder in stop-and-go traffic. However, the 30 MPG highway rating demonstrates the engine’s ability to cruise efficiently at higher speeds. The smooth-shifting 9-speed automatic transmission (S9) helps optimize fuel economy on the open road, keeping the engine in its sweet spot. This difference in fuel economy suggests that drivers who spend more time on the highway will see numbers closer to the EPA combined estimate.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2019 Acura TLX FWD A-SPEC 3.5L is $2,500. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs could vary depending on your driving habits, the type of fuel you use, and local fuel prices. Those with a heavy foot or who primarily drive in congested city traffic will likely exceed this estimate. However, conservative drivers who stick to highway cruising may find themselves spending less.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. Factors like driving style, weather conditions, and even tire pressure can impact your MPG. Drivers who frequently engage the TLX A-SPEC’s Sport mode will undoubtedly see a dip in fuel economy, as the engine holds gears longer and responds more aggressively.

Similarly, using the air conditioning heavily, especially in hot climates, will strain the engine and lower your MPG. Monitoring your trip computer and adjusting your driving habits can help you achieve numbers closer to the EPA estimates.

How it compares

Compared to its competitors, the 2019 TLX A-SPEC 3.5L’s fuel economy is in the middle. For example, the Lexus ES 350, with its V6 engine, achieves a slightly better 26 MPG combined. The BMW 330i, with its turbocharged four-cylinder, manages around 28 MPG combined, showing a focus on efficiency. However, those cars don’t offer the specific blend of V6 power and visual aggression that the A-SPEC provides. If fuel economy is a top priority, alternatives like the Acura TLX 2.4L (non-A-SPEC) offer better numbers across the board.

Tips to maximize efficiency

Avoid aggressive acceleration. The TLX A-SPEC’s V6 is responsive, but launching from every stoplight will significantly reduce fuel economy. Smooth, gradual acceleration allows the engine to operate more efficiently and helps to conserve fuel. Anticipate traffic flow and maintain a steady speed.

Maintain proper tire inflation. Underinflated tires create more rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the driver’s side door jamb. This maintenance task can improve your fuel economy.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, preventing unnecessary acceleration and deceleration. This is helpful on long highway drives where speed changes can impact fuel economy. Be mindful of traffic conditions and disengage cruise control when needed.

Minimize idling. Extended idling wastes fuel. If you’re going to be stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and restarting consumes less fuel than idling for an extended period. This habit can add up to fuel savings.
