23 MPG combined is what you can expect from the 2020 Acura TLX with all-wheel drive and the reliable 3.5L V6. This TLX configuration prioritizes smooth, responsive power and sure-footed traction over saving gas. The target customer appreciates a refined driving experience, doesn’t want to compromise on all-weather capability, and is willing to use a little more gas for the satisfaction the V6 provides.

City and highway performance

The EPA estimates this TLX achieves 20 MPG in the city and 29 MPG on the highway. The city number reflects the engine’s need to work harder in stop-and-go traffic, where the nine-speed automatic transmission is constantly shifting to find the optimal gear. The highway figure, while respectable, means that even with an advanced transmission, a naturally aspirated V6 will always need to burn a decent amount to maintain higher speeds. Consider it the price for that classic Acura driving experience: smooth power delivery and a satisfying engine note.

Annual fuel cost

The EPA calculates an annual fuel cost of $2,500 for this version of the 2020 Acura TLX. This figure is based on driving 15,000 miles per year, using the national average fuel price at the time of calculation, and the vehicle’s combined MPG rating. Remember that your actual fuel costs will vary depending on your driving habits, local fuel prices, and the type of fuel you use. Aggressive acceleration, frequent short trips in cold weather, or consistently using premium fuel when regular is recommended can all significantly impact your yearly fuel expenditures.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world MPG often differs. TLX owners report numbers slightly below the EPA figures in mixed driving. This is especially true for those who enjoy pushing the V6 engine. Expect to see numbers closer to the high teens in predominantly city driving and potentially exceeding the 29 MPG highway figure on longer road trips, especially when using cruise control. Tire pressure, vehicle maintenance and cargo weight can also influence these figures.

How it compares

The fuel economy of the 2020 Acura TLX AWD V6 places it in the middle of its competitive set. The BMW 330i xDrive achieves a slightly better 28 MPG combined with its turbocharged four-cylinder engine, demonstrating the efficiency gains offered by smaller engines. The Lexus ES 350, another popular alternative, boasts a similar 26 MPG combined with its V6, showcasing Lexus’ engineering. A comparably equipped INFINITI Q50 with all-wheel drive and its 3.0-liter twin-turbo V6 nets near-identical figures to the Acura at 22 MPG combined. For buyers prioritizing lower fuel costs, perhaps the four-cylinder TLX configuration or a hybrid competitor like the Lexus ES 300h (44 MPG combined) would make more sense. For shoppers who value the unique V6 experience and sure-footedness of all-wheel drive from a brand they trust, TLX MPG across all years makes the trade-offs justifiable.

Tips to maximize efficiency

One of the easiest ways to improve fuel economy in your TLX is monitoring your tire pressure. Ensure your tires are inflated to the recommended pressure, typically found on a sticker inside the driver’s side door jamb. Under-inflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel.

Avoid aggressive acceleration and excessive braking. The TLX’s V6 loves to rev, but frequent hard acceleration will dramatically reduce fuel economy. Anticipating traffic flow and maintaining a steady speed helps the automatic transmission stay in higher, more efficient gears. Use the paddle shifters carefully; while they’re fun for spirited driving, leaving the transmission in “Drive (D)” generally maximizes efficiency during normal commuting.

Consider using the TLX’s “Econ” mode for everyday driving. This mode adjusts throttle response and transmission mapping to prioritize fuel efficiency. While it may slightly dull the engine’s responsiveness, the fuel savings can be noticeable, especially during city driving. Likewise, cruise control can be used when possible on the highway. Maintaining a consistent speed minimizes unnecessary acceleration and deceleration, optimizing fuel consumption.

Regular maintenance is important for optimal fuel economy. Ensure your TLX receives timely oil changes, air filter replacements, and spark plug servicing. A well-maintained engine operates more efficiently, maximizing power output and minimizing fuel consumption. Before opting for an aftermarket engine air filter, consider that TLX engine management systems are most likely optimized for the factory part.

Minimize unnecessary weight in your vehicle. Extra cargo in the trunk or rear seats adds to the vehicle’s overall weight, requiring the engine to work harder. Remove any items you don’t need to carry regularly. Evaluate adding a roof rack only if you will use it regularly, as even an unloaded rack adds aero drag and weight.
