While 28 MPG combined might not set any records, it’s a practical balance for the 2019 Acura ILX with the 2.4L 4-cylinder. The ILX isn’t chasing hybrid efficiency; it delivers accessible luxury with a dash of sporty flair. Its target buyer prioritizes the Acura badge, the engaging driving experience from its naturally aspirated engine and 8-speed dual-clutch transmission, and a reasonable cost to enter the premium segment. Fuel economy, while important, plays a secondary role for the typical ILX shopper behind those more emotional considerations.

City and highway performance

The EPA estimates for the 2019 Acura ILX are 24 MPG in the city and 34 MPG on the highway. These numbers reflect the engine’s tuning and the transmission’s programming, designed to provide both responsive acceleration and efficient cruising. The 2.4L engine, requiring premium fuel, offers a more engaging and linear power delivery than many turbocharged competitors.

The 8-speed dual-clutch automatic transmission contributes significantly to both performance and economy, offering quick, precise shifts and a wide ratio spread to optimize engine speed in various driving conditions. While the city figure lags behind some rivals, the highway MPG holds its own, making it a decent choice for those with a mixed commute.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Acura ILX at $2,050. This is based on driving 15,000 miles per year and using national average fuel prices. This number is a benchmark for consumers to compare the ILX to other vehicles in its class and to estimate their own potential fuel expenses based on their driving habits and local fuel costs.

While market fluctuations will change the price of fuel, $2,050 represents the EPA’s method of determining your running cost in a standardized fashion.

Real-world expectations

Achieving the EPA’s numbers in the real world depends heavily on driving style and conditions. Aggressive acceleration, frequent stop-and-go traffic, and sustained high-speed cruising will all negatively impact fuel economy. Smooth, deliberate driving and adherence to posted speed limits will help maximize fuel efficiency.

Owners generally report figures that align with the EPA estimates, though some see slightly lower numbers around town because the engine requires some revs to get into its powerband. Overall, drivers should expect a realistic combined MPG in the mid-to-high 20s with careful driving, something in-line with ILX MPG across all years.

How it compares

Compared to its competitors, the 2019 Acura ILX’s fuel economy is in the middle of the pack. For example, the 2019 Audi A3 2.0T quattro achieves around 25 MPG combined, sacrificing some efficiency for all-wheel drive. The 2019 Mercedes-Benz A220 manages about 28 MPG combined, similar to the ILX, but with a turbocharged engine delivering power in a different manner.

The Lexus CT 200h, while technically a hatchback, can be cross-shopped by the same buyers, offering considerably better fuel economy at around 42 MPG combined, but with a noticeably different driving experience. The ILX’s fuel economy is a trade-off; it’s not the most efficient choice, but it offers a specific blend of performance and luxury that appeals to a particular segment within the entry-level luxury market.

Tips to maximize efficiency

Use the ILX’s Intelligent Multi-Mode Drive system. Use the “Econ” mode in steady-state cruising to optimize throttle response and gear selection for efficiency. Switch to “Normal” or “Sport” mode when you want more spirited performance, understanding that fuel consumption will increase.

Maintain proper tire inflation. Under-inflated tires increase rolling resistance, which directly impacts fuel economy. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure for your ILX and check it regularly.

Minimize unnecessary weight. Carrying heavy items in the trunk or back seat reduces fuel economy. Remove any items you don’t need regularly to lighten the load and improve efficiency on typical drives.

Anticipate traffic flow and avoid aggressive acceleration and braking. Smooth and consistent driving maximizes fuel economy in any vehicle, but particularly in the ILX with its responsive engine and transmission. Plan ahead to minimize hard stops and bursts of acceleration.

Use cruise control on the highway. Maintaining a consistent speed with cruise control typically results in better fuel economy than constantly adjusting the throttle. This is helpful on long highway drives, and the ILX’s adaptive cruise control makes this easier.
