25 MPG combined isn’t going to set any records, but it represents a reasonable compromise for the 2017 Acura TLX AWD 3.5L. This isn’t a fuel-sipping hybrid; it’s a comfortably appointed sedan offering sure-footed all-wheel drive and a willing V6 engine. Buyers in the market for this specific TLX configuration understand that they are prioritizing confident performance and all-weather capability over outright efficiency. They accept the fuel economy trade-off because it aligns with their driving needs and the overall character of the car.

City and highway performance

The EPA estimates for the 2017 Acura TLX AWD 3.5L break down to 21 MPG in the city and 31 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, something any driver in a densely populated area knows all too well. The engine requires more fuel to accelerate from a standstill, and idling consumes fuel without covering any distance. The highway figure showcases the engine’s ability to cruise efficiently at a steady speed. Credit goes to the nine-speed automatic transmission (S9), which allows the engine to operate at lower RPMs for reduced fuel consumption. Achieving the stated highway MPG requires a conscious effort to maintain a consistent speed and avoid aggressive acceleration; this can be difficult with the TLX’s responsive V6.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Acura TLX AWD 3.5L at $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. While $2,300 provides a benchmark, your actual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and the prevailing fuel prices in your area. Someone who primarily drives short distances in the city will likely exceed this estimate, while someone who predominantly drives longer distances on the highway may spend less. This also assumes regular fuel; premium fuel is recommended for optimal performance, which would inflate this annual cost figure.

Real-world expectations

While the EPA estimates provide a useful point of comparison, real-world fuel economy often deviates from the official numbers. The 2017 Acura TLX AWD 3.5L is no exception. Aggressive driving, frequent short trips, and extreme weather conditions can all negatively impact fuel efficiency. However, drivers who adopt a more conservative driving style and prioritize highway miles should find it possible to achieve figures close to, or even slightly above, the EPA estimates. Tire pressure, vehicle maintenance, and even the type of gasoline used can also play a role in determining real-world fuel economy.

How it compares

Compared to its competitors, the 2017 Acura TLX AWD 3.5L occupies a middle ground in terms of fuel economy. For example, the comparable Lexus IS 350 AWD is rated at 22 MPG combined, 19 MPG city, and 26 MPG highway, putting it slightly behind the TLX. The BMW 340i xDrive, while offering more power and a sportier driving experience, achieves a similar 25 MPG combined, though it requires premium fuel. On the more efficient end, the Audi A4 quattro achieves around 27 MPG combined largely due to its turbocharged 4-cylinder engine, but sacrifices the sound and smoothness of a V6. This comparison matters to the TLX buyer because it highlights the compromise they are making: they’re not seeking the absolute best fuel economy, but rather a balance of performance, all-weather capability, and reasonable efficiency.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel efficiency in the 2017 Acura TLX AWD 3.5L. Avoid sudden bursts of speed and instead, gradually increase your speed. The V6 has plenty of power, but using it carefully will save fuel. Pay attention to the road ahead and anticipate traffic flow to avoid unnecessary braking and acceleration.

Maintain a consistent speed on the highway to optimize fuel economy. Using cruise control can help with this, especially on long drives. The TLX’s adaptive cruise control feature can also assist in maintaining a safe following distance while optimizing fuel efficiency, though its effectiveness will depend on traffic conditions.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure specified on the sticker inside the driver’s side doorjamb. Proper tire maintenance improves both fuel efficiency and handling.

Reduce unnecessary weight in the vehicle. Carrying extra weight requires the engine to work harder, which consumes more fuel. Remove any unnecessary items from the trunk and passenger compartment to improve fuel efficiency. Consider cleaning out the car every few weeks to remove any accumulated items that weigh it down.

Consider the Drive Mode selector. The TLX features distinct drive modes that impact efficiency: Econ, Normal, Sport, and Sport+. For maximum MPG, try sticking to Econ. Also, be aware that choosing a drive mode that increases RPMs (such as Sport+) can change your TLX MPG across all years.
