If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.

Key takeaways

  • The most efficient car in the Compact Cars class for the 2022 model year is the Porsche Taycan GTS at 83 MPG.
  • EPA estimates this car costs around $1,500 more in fuel over five years than an average new vehicle of the same model year.

Fuel economy at a glance

These are the EPA's official ratings for the 2022 Acura ILX. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.

Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

Combined MPG 28 MPG
City MPG 24 MPG
Highway MPG 34 MPG
Annual fuel cost $2,450
Tailpipe CO₂ 316 g/mi
Fuel type Premium

Annual fuel cost across driving patterns

The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for premium gasoline, which is $4.61/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.

The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 535.7 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $1,225
Average driver, 15,000 miles per year $2,450
Heavy driver, 25,000 miles per year $4,083

Specifications

The 2022 Acura ILX runs a 2.4-liter 4-cylinder engine paired with a automatic (am-s8), sending power through front-wheel drive.

Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
