For the 2021 Acura ILX 2.4L 4-cyl, 28 MPG combined fuel economy is acceptable. This compact luxury sedan targets a buyer who appreciates the Acura brand, the responsive, naturally aspirated engine, and the composed handling. These features are appealing without the high price or excessive fuel consumption. For these drivers, the ILX’s efficiency doesn’t have to rival the latest hybrids.

City and highway performance

The ILX achieves 24 MPG in city driving and 34 MPG on the highway. In stop-and-go conditions, expect the city figure. The eight-speed dual-clutch automatic transmission (AM-S8) enhances highway fuel conservation by allowing the engine to cruise at lower RPMs. Aggressive driving will hurt both figures. Moderate throttle and anticipate traffic to maximize efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Acura ILX 2.4L 4-cyl at $2,050. This is based on 15,000 miles per year, with 55% in the city and 45% on the highway, using national average fuel prices. Individual fuel costs will vary with driving habits, local fuel prices, and gasoline grade. This $2,050 estimate is a useful benchmark but check all Acura fuel economy data to compare it to Acura’s lineup.

Real-world expectations

EPA estimates are a standardized benchmark, but real-world fuel economy varies. Some ILX owners report figures close to the EPA estimates and even exceeding the highway MPG on long trips. Fuel consumption is affected by driving style, traffic, and tire pressure. Regular maintenance, including oil changes and air filter replacements, maintains fuel efficiency.

How it compares

The ILX’s fuel economy is mid-pack. In front-wheel drive, the 2021 Audi A3 achieves a combined 32 MPG. The BMW 228i Gran Coupe manages a combined 28 MPG, on par with the Acura. With its base 2.0L turbocharged engine, the Lexus IS 300 comes in at 25 MPG combined. The ILX is slightly more efficient. Some buyers might also consider the Honda Civic Si, which offers similar performance and driving enjoyment with better fuel economy.

Tips to maximize efficiency

Drive smoothly to allow the efficient eight-speed dual-clutch transmission to shift into higher gears quickly. Avoid aggressive acceleration when merging or overtaking, as it wastes fuel and does not greatly affect arrival time. Also research ILX MPG across all years if you are considering other model years.

Ensure tires are at the pressure listed on the driver’s side door. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check tire pressure regularly, especially during temperature changes.

Minimize weight in the vehicle. Extra cargo reduces fuel economy. Remove unneeded items to lighten the load.

Use cruise control on the highway to maintain speed. Maintaining a steady speed helps your ILX optimize fuel consumption. However, be mindful of traffic and adjust your speed for safety.

Avoid idling. Turn off the engine if you’re stopped for more than a minute. Modern engines restart quickly, and idling wastes fuel.
