With 24 MPG combined, the 2020 Acura TLX V6 isn’t trying to redefine fuel efficiency. It’s a mid-size sport sedan with a proven V6 engine, one that appeals to drivers who value a responsive throttle and a smooth power delivery over squeezing every last mile from a gallon of premium unleaded. The TLX V6 buyer prioritizes a satisfying driving experience and Acura’s reputation for reliability; fuel economy is a consideration, but not the deciding factor.

City and highway performance

The EPA estimates 20 MPG in the city and 31 MPG on the highway for the front-wheel-drive 2020 Acura TLX equipped with the 3.5L V6 and 9-speed automatic transmission. The city figure reflects the reality of stop-and-go driving, where the engine spends more time idling or accelerating from a standstill, impacting efficiency. The highway number is respectable, showcasing the benefits of the transmission’s tall top gear, which allows the engine to cruise at lower RPMs. These figures are based on standardized testing; your actual mileage will vary depending on driving style, traffic conditions, and vehicle maintenance.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 Acura TLX V6 at $2,400 per year. This is based on driving 15,000 miles annually, using the EPA’s estimate of prevailing fuel prices. It’s a useful benchmark for comparing the running costs of different vehicles, but your personal fuel expenses may differ significantly based on where you live and how you drive. Fuel prices fluctuate, and aggressive driving habits can easily push that $2,400 figure higher.

Real-world expectations

While the EPA provides standardized figures, expect real-world fuel economy to fluctuate. Aggressive acceleration, frequent short trips, and extended idling will all reduce your MPG. Conversely, smooth acceleration, anticipatory braking, and sticking to highway speed limits will help you approach or even exceed the EPA estimates. Tire pressure, vehicle maintenance, and even the weather can play a role; colder temperatures generally reduce fuel efficiency.

How it compares

The 2020 Acura TLX V6’s fuel economy places it within a competitive set. For example, the front-wheel-drive V6-powered Lexus ES 350 achieves 26 MPG combined, exceeding the TLX by a small but measurable amount. The BMW 330i, with its turbocharged four-cylinder, offers a claimed 28 MPG combined, demonstrating the efficiency advantages of smaller, boosted engines. Acura fuel economy data also shows that the smaller, four-cylinder TLX variant can achieve slightly higher figures. The TLX MPG across all years reflects Acura’s focus on balancing performance and reasonable efficiency, rather than outright leadership in either category. A prospective TLX buyer needs to decide if the V6’s character and power are worth the trade-off when compared to more frugal competitors.

Tips to maximize efficiency

Use the TLX’s “Econ” mode for everyday driving. This setting remaps the throttle response and shift points to prioritize fuel efficiency over outright performance. It’s particularly effective in city driving, reducing the temptation to accelerate aggressively.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which directly impacts fuel economy. Check your tire pressure at least monthly and keep them inflated to the recommended levels found on the sticker inside the driver’s side doorjamb.

Avoid unnecessary idling. Modern engines are designed to be restarted frequently without causing excessive wear. If you’re going to be stopped for more than a minute, turn off the engine. This is especially relevant in city traffic, where idling can significantly reduce your overall MPG.

Anticipate traffic flow and practice smooth driving techniques. Avoid abrupt acceleration and braking, which waste fuel. By looking ahead and maintaining a consistent speed, you can significantly improve your fuel economy.

Minimize aerodynamic drag. Remove any roof racks or carriers when they are not in use, as they increase wind resistance and fuel consumption, particularly at highway speeds. Even cleaning off road grime can slightly reduce aerodynamic drag.
