25 MPG combined in the 2021 Acura TLX FWD A-Spec 2.0L won’t win any hypermiling contests, but it’s an acceptable trade-off for what this car offers: sharp styling, a responsive turbo engine, and a sporty driving experience that elevates it beyond the typical luxury sedan. This isn’t a car bought primarily for ultimate fuel efficiency; it’s a car for those who appreciate style and engagement and who are willing to live with slightly less-than-stellar MPG to get it.

City and highway performance

The EPA estimates 22 MPG in the city and 30 MPG on the highway for the 2021 Acura TLX FWD A-Spec. The city figure reflects the fuel demands of stop-and-go driving, where the engine frequently idles and accelerates from a standstill. The 30 MPG highway rating, however, paints a slightly rosier picture. This is where the TLX’s 10-speed automatic transmission helps optimize fuel consumption. The higher gears allow the engine to cruise at lower RPMs, reducing fuel burn during long highway stretches, so the Acura achieves solid performance on long trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Acura TLX FWD A-Spec at $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual costs will vary depending on driving habits and where you live, as local gas prices can fluctuate significantly. This provides a benchmark to assess the ongoing ownership expenses related to fuel.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world MPG often differs. Aggressive driving, frequent short trips, and even environmental factors like weather and terrain can impact fuel consumption. Expect figures that fluctuate slightly above or below the EPA’s estimates. Many owners report achieving numbers close to the EPA figures under normal mixed driving conditions, so this is the expected MPG for this trim level.

How it compares

Compared to its rivals, the 2021 Acura TLX FWD A-Spec sits in the middle of the pack. The BMW 330i, for example, achieves an EPA-estimated 26 MPG combined, offering slightly better fuel economy with similarly engaging driving dynamics. The Genesis G70 2.0T, another stylish competitor, mirrors the TLX at 25 MPG combined, while prioritizing value and features. The Lexus IS 300 RWD comes in lower, at 24 MPG combined. The TLX buyer likely isn’t making a decision based solely on fuel economy. They are balancing MPG with aesthetics, performance, and brand appeal, which is why this Acura remains popular.

Tips to maximize efficiency

Use the TLX’s drive modes. The “Econ” mode recalibrates the throttle response and transmission shift points for maximum fuel efficiency. Performance will be slightly reduced, but it can make a noticeable difference during everyday commuting.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which lowers fuel economy. Keeping your tires properly inflated not only improves MPG but also extends tire life and enhances safety.

Avoid aggressive acceleration and braking. The TLX’s turbo engine responds eagerly to throttle inputs, but excessive bursts of speed significantly impact fuel consumption. Smooth, gradual acceleration and gentle braking are key for maximizing efficiency.

Minimize idling. Letting the engine run unnecessarily wastes fuel. If you’re stopped for more than a minute or two, turn off the engine, especially during cold weather when idling is more common.

Service the vehicle at the recommended intervals. Regular maintenance, including oil changes and air filter replacements, ensures the engine runs efficiently. Following the manufacturer’s maintenance schedule can improve fuel economy.
