28 MPG combined won’t set the world on fire, but it reflects the 2020 Acura ILX 2.4L 4-cyl’s position in the market. It’s not a hybrid designed for hypermilers, but a gateway into the Acura brand. It’s aimed at younger buyers who prioritize style, reliability, and some sportiness over ultimate fuel efficiency. This group often accepts slightly lower MPG for the Acura badge and the engaging driving of the 2.4L engine and 8-speed dual-clutch transmission.

City and highway performance

The ILX’s EPA ratings are 24 MPG in the city and 34 MPG on the highway. The city number reflects stop-and-go traffic where the engine is less efficient. The 2.4L engine needs to rev to deliver its power. In dense urban environments, this means more fuel consumption than a smaller, turbocharged unit. The highway figure is better. The eight-speed dual-clutch transmission allows the engine to cruise at lower RPMs, optimizing fuel efficiency during sustained highway driving. The car’s shape also helps reduce drag at higher speeds, improving highway MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Acura ILX at $2,050. This is based on driving 15,000 miles per year and using national average fuel prices when calculated. It lets consumers compare fuel costs across different vehicles. Remember that this is an estimate, and actual fuel costs will vary depending on driving habits, fuel type, and local fuel prices. If you drive around 1,250 miles per month and fuel prices are average, expect to spend around $2,050 per year to keep your ILX running.

Real-world expectations

The EPA provides standardized testing, but real-world MPG often differs from the official numbers. ILX owners report figures close to the EPA estimates, especially on long highway trips. However, aggressive driving, frequent short trips, and heavy traffic can all hurt fuel economy. Consider the fuel type, too. The ILX doesn’t require premium fuel, but some drivers say they see slightly better performance and fuel economy when they use higher octane gasoline.

How it compares

The ILX’s fuel economy is competitive within the entry-level luxury sedan segment. The Mercedes-Benz A220 gets 28 MPG combined with a turbocharged engine prioritizing low-end torque. The Audi A3 achieves around 30 MPG combined. Even Acura’s Integra, revived in 2023, offers 33 MPG. The ILX offers an amazing driving experience, but it has an MPG cost. Buyers who want less gas might like those cars more, but the ILX’s naturally aspirated engine and dual-clutch transmission offer a driving experience that some find preferable, despite MPG.

Tips to maximize efficiency

The 2.4L engine in the ILX likes accelerating smoothly and moderately. Avoid hard acceleration, especially in the city, because it burns gas quickly. Watch traffic and keep a consistent speed when you can.

Regular maintenance is critical for fuel economy. Keep the ILX’s tires properly inflated, and the engine tuned as recommended. A well-maintained engine runs better, and inflated tires reduce rolling resistance.

The ILX’s paddle shifters offer gear control, but using “D” mode for most driving is usually best for fuel economy. The transmission selects the most efficient gear for driving.

Use air conditioning less, especially on short trips. The AC compressor strains the engine, increasing fuel use. Use the fan or open the windows to reduce the strain, but close your windows above 45mph.
