20 MPG combined isn’t usually a top concern for 718 Spyder buyers. This stunning open-top roadster prioritizes a visceral driving experience. Razor-sharp handling and the sound of its naturally aspirated engine are more important than fuel efficiency. It’s built for weekend canyon runs and spirited backroad adventures, where the reward lies in the driving sensation, not saving money at the gas pump.

City and highway performance

The 718 Spyder’s EPA ratings reflect the tradeoff for its performance. The city rating of 18 MPG results from the engine’s need to rev to deliver peak power, making it less efficient in stop-and-go conditions. The Spyder achieves 24 MPG on the highway, a slightly better number. This improvement suggests the Spyder isn’t entirely impractical for longer journeys, but expect higher fuel consumption than your average commuter car.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Porsche 718 Spyder at $2,900. This is based on driving 15,000 miles per year using current national average fuel prices. Your actual fuel expenses will vary depending on your driving habits, gasoline prices in your area, and how often you unleash the Spyder’s full potential. Considering that many owners likely won’t use this car as a daily driver, the annual cost may be less. This estimate is still a sobering reminder of the vehicle’s fuel requirements.

Real-world expectations

While EPA ratings offer a standardized benchmark, real-world fuel economy can differ. Aggressive driving, frequent acceleration, and extended periods in lower gears, all tempting in a 718 Spyder, will lower MPG. A gentler driving style and using cruise control on highways can help you approach the EPA estimates. Browse 718 MPG across all years and see if other owners report similar fuel economy.

How it compares

The 718 Spyder exists in a niche segment, making direct fuel economy comparisons difficult. Its closest rivals, like the BMW Z4 M40i (25 MPG combined) and Audi TTS (26 MPG combined), achieve better fuel efficiency because of their turbocharged engines. The Alpine A110, though not sold in the US with the same enthusiasm, achieves significantly higher MPG (around 34 MPG combined in European testing cycles). The Porsche suits drivers who want the feel of a natural aspirated engine, accepting lower fuel economy for it. For similar comparisons, browse all Porsche fuel economy data.

Tips to maximize efficiency

Resist constantly exploiting the engine’s high-revving nature. The 4.0L flat-six rewards those who explore its upper limits, but frequent use will hurt fuel economy. Shift smoothly and deliberately, and avoid unnecessary downshifts especially at higher speeds. Let the engine’s torque do the work when possible.

Tire pressure is critical, especially in a performance car like the Spyder. Underinflated tires increase rolling resistance, decreasing fuel economy and compromising handling. Regularly check and maintain the recommended tire pressure on the doorjamb sticker, when the tires are cold.

Consider how you use the car. Combining errands into fewer trips, rather than multiple short journeys, reduces fuel consumption by minimizing cold starts, which are less efficient. Simply plan your route to avoid traffic.

Remember that every pound counts. The Spyder isn’t designed to haul cargo, so avoid carrying extra weight, as it impacts fuel efficiency. Remove unnecessary items from the trunk and passenger area. Some owners even remove the front trunk’s carpet on track days to reduce vehicle weight, though that is extreme.
