30 MPG combined is a respectable figure for the 2023 Mazda MX-5 equipped with the 2.0L four-cylinder engine and automatic transmission, but focusing solely on that number misses the point entirely. No one buys an MX-5 expecting Prius-like efficiency. Buyers choose this car for its razor-sharp handling, open-air thrills, and a connection to the road that’s increasingly rare in modern automobiles. The MX-5’s fuel economy is simply the acceptable price to pay for admission into that world of driving enjoyment.

City and highway performance

The EPA estimates for the MX-5 in this configuration suggest 26 MPG in the city and 35 MPG on the highway. In reality, these figures are achievable, but your driving style will dramatically impact it. Aggressively accelerate out of corners and frequently downshift with the paddle shifters, and expect fuel economy to drop considerably. However, adopting a more relaxed driving style, focusing on smooth inputs and anticipating traffic, means you’ll likely meet or even exceed the EPA’s projections. The forgiving nature of the engine and well-spaced ratios of the automatic transmission genuinely aid in achieving consistent fuel efficiency.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,950 for the 2023 Mazda MX-5 with the automatic transmission. This figure is calculated based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate, and your actual fuel costs will vary depending on your driving habits, the type of fuel you purchase, and where you live. Regions with higher gas prices, obviously, will lead to a higher annual cost.

Real-world expectations

The MX-5’s fuel economy is predictable. While some modern turbocharged engines struggle to match EPA estimates in real-world use, the naturally aspirated 2.0L in the MX-5 generally performs very consistently. Expect to see figures in the high 20s or low 30s in mixed driving, with highway-only trips easily reaching the mid-30s. Those seeking the best possible mileage will likely do even better. Mazda’s engineering means that this car offers a delightful driving experience without sacrificing reasonable fuel efficiency.

How it compares

Compared to other sporty cars, the MX-5 fares quite well. The Toyota GR86, for instance, achieves a combined EPA rating of 25 MPG with the automatic transmission, making the MX-5 a noticeably more economical choice without sacrificing a similar fun driving experience. Even some economy cars, like the Honda Civic Si (rated at 31 MPG combined), only eke out a slightly better MPG, reinforcing the fact that the MX-5 offers remarkable efficiency for a sports car. The Nissan Z, while offering significantly more power, gets only 22 MPG combined. If you want to view all Mazda fuel economy data, you’ll see a trend that many of their vehicles hold decent fuel efficiency. The MX 5 MPG across all years has remained pretty consistent, even as technology changes.

Tips to maximize efficiency

The most effective way to improve the MX-5’s fuel economy is to adopt a smoother driving style. Avoid sudden acceleration and braking, and anticipate traffic flow to maintain a consistent speed. The MX-5 rewards finesse, and driving smoothly not only saves fuel but also enhances the overall driving experience.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which puts extra strain on the engine and reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the door jamb sticker.

Reduce unnecessary weight in the vehicle. Carrying extra cargo in the trunk adds weight, which requires more energy to move. Remove any items you don’t need to improve fuel efficiency, but please drive safely.

Use the automatic transmission’s shift lever intelligently. While the MX-5’s automatic is generally well-tuned, using the manual shift mode to hold gears on long inclines or when anticipating spirited driving can help optimize fuel consumption and ensure the engine isn’t constantly shifting unnecessarily, even if it’s fun.

Consider opting for a fuel additive designed to clean fuel injectors and maintain optimal engine performance. A clean engine runs more efficiently, leading to improved fuel economy over time. A well-maintained Mazda MX-5 is a happy and efficient Mazda MX-5.
