The 2025 Acura Integra 1.5L 4-cyl achieves 33 MPG combined, confirming its place as a stylish and sporty daily driver that won’t break the bank when you fill up. It’s not a hyper-efficient hybrid or a gas-guzzling performance monster. It’s an Integra, designed for young professionals and those who value both a premium driving experience and reasonable running costs. These buyers are willing to trade ultimate fuel efficiency for Acura’s reputation for reliability, sharp handling, and a touch of luxury.

City and highway performance

The EPA breaks down the Integra’s fuel consumption further, reporting 30 MPG in the city and 37 MPG on the highway. The strong highway number shows the Integra’s well-tuned engine and smooth-shifting automatic transmission (AV-S7) work well. This is ideal for those who commute longer distances or frequently take road trips. The city figure, while lower, is still respectable for a non-hybrid vehicle, meaning stop-and-go traffic won’t disproportionately drain the fuel tank. The 1.5L engine provides ample power for merging and passing, striking a balance between performance and efficiency, helping its popularity in urban environments.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Acura Integra 1.5L 4-cyl at $1,750. This number is based on driving 15,000 miles per year using national average fuel prices. Actual fuel cost will vary depending on individual driving habits, local fuel prices, and even weather conditions. However, the $1,750 provides a benchmark for comparing the Integra’s running costs to other vehicles in its class. If you drive significantly more or less than 15,000 miles annually, you can adjust that number to better estimate your specific expenses.

Real-world expectations

EPA ratings provide a standardized comparison point, but real-world fuel economy can differ. Aggressive driving, meaning hard acceleration and braking, will negatively affect MPG. The same is true for carrying heavy loads or driving in challenging conditions like snow or strong headwinds. However, careful drivers can often meet or even slightly exceed the EPA estimates, particularly on long highway trips. The 33 MPG combined figure represents a realistic expectation for the typical Integra owner, even with some spirited driving.

How it compares

The Integra faces many competitors in the small car segment, and its fuel economy holds up well against them. The Honda Civic Si, for example, delivers a slightly lower 31 MPG combined, trading some efficiency for more performance. The Mazda3 with its standard engine manages around 32 MPG, nearly identical to the Integra. Even the Lexus IS 300, offers a more luxurious experience, but it struggles to surpass 25 MPG combined. For those seeking even greater fuel efficiency, hybrid options such as the Toyota Corolla Hybrid achieve upwards of 50 MPG, but they come with a different driving experience and price point. Exploring all Acura fuel economy data is a good place to start for more information on the Integra’s place within the brand’s lineup. You can also look into INTEGRA MPG across all years to compare its efficiency across model years.

Tips to maximize efficiency

Drive smoothly to save fuel. Avoid sudden acceleration and braking, because these consume more fuel. Anticipate traffic flow and maintain a steady speed when you can. This is especially relevant for the Integra, since its responsive engine can tempt drivers use more power than necessary.

Make sure your tires are properly inflated. Low tire pressure increases rolling resistance, reducing fuel economy. Check your tire pressure regularly and inflate them to the recommended specifications found on the driver’s side doorjamb. Properly inflated tires improve fuel efficiency and enhance handling and tire life.

Reduce unnecessary weight. Carrying extra weight in your vehicle decreases fuel economy. Remove any items you don’t need, such as golf clubs, sporting equipment, or old tools. The lighter the vehicle, the less fuel it burns.

Consider using cruise control on long highway drives. Cruise control helps maintain a consistent speed, which can improve fuel economy. Avoid using cruise control in hilly terrain, as the vehicle may downshift frequently, negating any potential fuel savings.
