The 2020 Mazda MX-5 2.0L, equipped with the automatic transmission, achieves an EPA-estimated 30 MPG combined. This isn’t about saving money for massive road trips or commuting, it’s about preserving some responsibility while indulging in pure driving joy. The MX-5 buyer isn’t prioritizing ultimate efficiency, but they also don’t want to feel irresponsible at the pump. 30 MPG is an acceptable compromise for top-down motoring.

City and highway performance

The city and highway MPG numbers provide a more specific view of the MX-5’s consumption. The EPA estimates 26 MPG in the city, reflecting the engine’s responsiveness and relatively light weight, key to navigating stop-and-go traffic. On the highway, the MX-5 reaches 35 MPG. This is adequate for weekend escapes. While not optimized for long-distance cruising, this car is more than capable of efficiently handling highway speeds during a drive to the coast or the mountains.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2020 Mazda MX-5 2.0L is $1,950. This figure is based on driving 15,000 miles per year and using national average fuel prices. These are EPA estimates for “typical driving habits.” If you use the MX-5 primarily for weekend fun, and drive less frequently, your annual cost could be lower. If you commute long distances, prepare for slightly higher fuel bills.

Real-world expectations

EPA fuel economy numbers are a good starting point, but real-world results always vary. The MX-5’s mileage can depend heavily on driving style. A gentle foot will often see numbers right in line with the EPA’s estimates, or even slightly better on the highway. However, using the engine’s rev-happy nature and embracing a more aggressive driving style will lead to lower MPG figures. Factors like tire pressure, ambient temperature, and even the weight of luggage or passengers can influence fuel consumption.

How it compares

The MX-5 isn’t about outright fuel efficiency but it’s informative to see how it stacks up against alternatives. The Fiat 124 Spider, which shares its platform and engine with the MX-5, achieves nearly identical fuel economy figures. Looking beyond roadsters, a sporty hatchback like the Honda Civic Si offers similar driving engagement with better practicality and a slightly lower EPA combined rating of 28 MPG. A Subaru BRZ offers a more rigid, track-focused experience but delivers around 25 MPG combined. These alternatives appeal to drivers who value a sporty experience, but who have different priorities relating to passenger space, cargo capacity, or budget. For drivers seeking wind-in-your-hair thrills, the MX-5’s fuel economy is acceptable, with all Mazda fuel economy data easy to find online.

Tips to maximize efficiency

The MX-5 is lightweight, and this plays a role in its respectable fuel economy. Avoid adding unnecessary weight to the car. Removing extra items from the trunk and passenger area will contribute to better gas mileage, particularly around town.

Proper tire inflation is critical. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications. Over- or under-inflated tires not only reduce fuel economy but also affect handling and tire wear. Use the values on the sticker inside the driver’s door.

Gentle acceleration and smooth braking are key to saving fuel in any vehicle, and the MX-5 is no exception. Avoid aggressive driving habits, such as rapid acceleration and hard braking. Anticipate traffic conditions and maintain a steady pace.

The automatic transmission in the MX-5 is responsive and efficient. Make sure you aren’t constantly triggering downshifts with excessive throttle input. Let the transmission do its job and avoid revving the engine to extract performance. The car is tuned for low-end torque, so use it.

Plan your trips wisely. Combining errands into a single journey avoids multiple cold starts, which consume more fuel as the engine warms up. Route carefully when possible, to use highways with longer sustained speeds. You can see MX 5 MPG across all years on other pages of this website.
