29 MPG combined isn’t going to win any hypermiling contests, but in a 2018 Mazda MX-5 2.0L it’s almost beside the point. This isn’t a car bought for its efficiency; it’s bought for the sheer joy of driving, the wind in your (possibly thinning) hair, and the connection you feel with the road. If you’re prioritizing ultimate fuel savings above all else, you’re shopping in the wrong aisle. The MX-5 is about smiles per gallon, not miles per gallon, though it’s still respectable for a sports car.

City and highway performance

The EPA estimates the 2018 Mazda MX-5 with the 2.0L four-cylinder and automatic transmission at 26 MPG in the city and 35 MPG on the highway. These numbers reasonably reflect a balance between spirited driving and reasonable efficiency. The highway figure is particularly useful for weekend getaways, top down of course. The city number reflects the car’s eagerness to rev and its nimble handling in urban environments. These figures are often bested by drivers who are mindful of fuel consumption. The responsive engine and relatively light vehicle weight contributes greatly to these numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Mazda MX-5 at precisely $2,000. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will fluctuate depending on where you live, how you drive, and current gasoline prices, but it provides a useful benchmark point of comparison to other vehicles in its class. A driver who primarily uses their MX-5 for short weekend pleasure drives will likely spend substantially less, while someone who commutes daily in heavy traffic may find that figure to be closer to reality. Use this data carefully, it is just an estimate.

Real-world expectations

While the EPA numbers are a good starting point, real-world fuel economy can vary. Owners often report figures that fall slightly above or below the official estimates depending on their driving style and conditions. Enthusiastic driving, particularly on winding roads, will naturally decrease fuel economy.

Careful and mindful driving on the highway, with the cruise control engaged, can often achieve a better MPG than the official 35 MPG. The MX-5’s small fuel tank means you’ll be visiting the gas station fairly frequently, but that’s a trade-off most drivers are willing to make for the driving experience.

How it compares

Compared to other sporty and fun-to-drive cars, the 2018 Mazda MX-5 holds its own in terms of fuel efficiency. A comparable Subaru BRZ or Toyota 86, with similar engine output and driving dynamics, often hovers around 24 MPG combined. A Nissan 370Z, with its powerful V6 engine, achieves significantly lower fuel economy in the high teens. The Fiat 124 Spider, which shares its platform with the MX-5 but features a turbocharged engine, delivers generally similar MPG, another indication that Mazda’s naturally aspirated engine is a solid choice. Owners who regularly monitor the MX 5 MPG across all years often find it favorably compares to other vehicles they’ve considered, especially since it’s often a secondary/fun car.

Tips to maximize efficiency

While fuel economy might not be the primary concern for MX-5 owners, there are still ways to improve it. Avoid aggressive acceleration and braking. The MX-5 is lightweight and responsive, so you don’t need to push it hard to enjoy it. Gentle inputs will save you fuel.

Maintain proper tire pressure. Underinflated tires increase rolling resistance and reduce fuel efficiency. Check your tire pressure regularly and inflate them to the recommended specifications listed on the doorjamb sticker.

Minimize idling. Idling consumes fuel without covering any distance. If you’re stopped for more than a brief moment, turn off the engine. This is especially relevant in city driving.

Use cruise control on the highway. Maintaining a consistent speed can improve fuel economy, particularly on long journeys. The MX-5’s cruise control system is easy to use and will prevent unintentional speed increases, maximizing your MPG.

Remember that roof up or down, this is not going to dramatically affect your MPG. Don’t worry about sacrificing open air enjoyment to slightly maximize fuel efficiency. For more details, check all Mazda fuel economy data. Buyers of this car accept it is not a hybrid, and plan to enjoy it!
