The 2018 Acura TLX AWD A-SPEC with the 3.5L V6 gets 23 MPG combined. This might seem high compared to some four-cylinder rivals, but it’s designed for someone who wants the smooth power and confident all-weather grip of a V6 and all-wheel drive, even if it means sacrificing some fuel economy. It’s about enjoying a well-balanced sport sedan that delivers a satisfying driving experience year-round, not hypermiling.

City and highway performance

The EPA breaks down the TLX AWD A-SPEC’s fuel economy to 20 MPG in the city and 29 MPG on the highway. The city figure reflects the engine’s demands during stop-and-go driving, where the all-wheel-drive system’s added weight reduces efficiency. However, the 29 MPG highway rating shows that the 3.5L V6 can be relatively efficient when cruising at consistent speeds. The nine-speed automatic transmission (S9) is important here, keeping the engine in its most economical range when possible. Understanding this split is key to managing fuel costs, especially for drivers with longer commutes or frequent highway trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Acura TLX AWD A-SPEC at $2,500. This is based on driving 15,000 miles per year and national average fuel prices at the time of calculation. It’s a useful benchmark for comparing running costs with other vehicles, but actual fuel costs can vary depending on driving habits, local fuel prices, and fuel type. Premium fuel, which is recommended for optimal performance, will increase this annual cost.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often differs. Aggressive driving, heavy acceleration, and frequent short trips can negatively impact fuel efficiency. Factors like tire pressure, vehicle maintenance, and even weather conditions can influence MPG. Expect to see numbers close to the EPA estimates with careful driving, but don’t be surprised if your averages are slightly below, especially if you frequently use the V6’s power. Track your own fuel economy to gain a realistic understanding of your TLX’s consumption.

How it compares

The TLX AWD A-SPEC’s fuel economy sits in an interesting spot. A similarly equipped Lexus IS 350 AWD achieves around 22 MPG combined. An Audi A4 with Quattro all-wheel drive and the 2.0T engine returns around 27 MPG combined, but lacks the Acura’s V6 power. A BMW 330i xDrive manages similar MPG to the Audi. The front-wheel-drive, four-cylinder TLX models offer significantly better fuel economy, but for the buyer prioritizing the A-SPEC’s styling and the V6/AWD combination, the trade-off is accepted.

Tips to Maximize Efficiency

Smooth acceleration is key to optimizing fuel economy in the TLX AWD A-SPEC. Avoid aggressive throttle inputs and try to maintain a steady speed. The nine-speed automatic transmission is programmed to shift efficiently, so let it do its job without constantly demanding downshifts.

Proper tire inflation is important for fuel efficiency. Check your tire pressure regularly and ensure it matches the recommended levels on the doorjamb sticker. Underinflated tires create increased rolling resistance, which negatively impacts MPG.

Reduce unnecessary weight. Carrying excessive cargo in the trunk or back seat adds weight, forcing the engine to work harder and consume more fuel. Remove any items you don’t need to carry regularly.

When possible, use cruise control on the highway. Cruise control helps maintain a constant speed, minimizing fluctuations in fuel consumption. This is effective on long, flat stretches of road where speed variations are minimal.

Regular maintenance is crucial for optimal fuel economy. Ensure the engine is properly tuned, the air filter is clean, and the oil is changed according to the manufacturer’s recommendations. A well-maintained engine runs more efficiently and delivers better MPG.
