24 MPG combined isn’t going to win any awards, but the 2023 Porsche 718 Boxster 2.0L isn’t about sipping fuel. It’s about open-air thrills, perfectly balanced handling, and the visceral joy of driving. This number simply represents the price of admission to a very exclusive club.

City and highway performance

The 718 Boxster’s EPA ratings break down to 21 MPG in the city and 27 MPG on the highway. The city figure reflects the stop-and-go driving typical of urban environments. The relatively low city MPG is partly explained by the engine needing to work harder getting the car moving, but mostly by the temptation to exploit the engine’s responsive throttle in urban driving. The highway MPG is more respectable, achievable when cruising at a steady speed. Owners, however, rarely buy a Boxster to achieve efficiency. They likely bought the car to drive on roads where the 6-speed manual, precise steering, and mid-engine balance can be enjoyed at its peak.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Porsche 718 Boxster 2.0L at $2,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s critical to remember that this is only an estimate, and your actual fuel costs may vary significantly. Factors like your driving style, the type of fuel you use, and the amount of city versus highway driving you do will all influence the final number. However, for individuals considering this class of vehicle, the $2,400 estimation is a good indicator that the Porsche 718 is not the most fuel efficient in its class, especially compared to gas/electric hybrid vehicles.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. Owners frequently report numbers that fluctuate based on driving habits. Consistent aggressive acceleration and frequent track days will push fuel economy well below the official ratings. Conversely, drivers who prioritize smooth, deliberate inputs and spend more time on the highway may see figures closer to, or even slightly above, the EPA estimates. The 2.0L turbo engine is surprisingly efficient when driven moderately, but its addictive power delivery often encourages a heavier foot. To see 718 MPG across all years, view our model page.

How it compares

The Porsche 718 Boxster occupies a unique space in the sports car market. Focusing purely on fuel economy, some competitors fare better. The BMW Z4 sDrive30i, for example, boasts a combined EPA rating of 28 MPG with its 2.0L turbo engine. The Audi TT Coupe, with its 2.0L turbo-4 and standard quattro all-wheel drive, achieves around 26 MPG combined. However, these cars offer a different driving experience and attract a different type of buyer. A prospective Boxster owner cares more about the mid-engine layout, chassis tuning, and pure driving feedback, something the German automaker is well known for. For those interested in lower fuel consumption, you might consider researching all Porsche fuel economy data to view plug-in hybrid and full electric vehicle (EV) models.

Tips to maximize efficiency

Despite the 718 Boxster’s performance-oriented nature, there are ways to optimize fuel consumption. The car’s drive mode selector allows the driver to switch the Porsche 718 from Sport mode to Normal mode, which makes a difference in overall MPG through shifting pattern and throttle mapping.

The 718 Boxster responds well to smooth, progressive acceleration. Avoiding sudden bursts of speed and maintaining a steady pace can significantly improve fuel economy, especially in city driving, but knowing the limits of your engine and applying the right amount of pressure will extend the life span of your vehicle.

Proper tire inflation is important. Ensure your tires are inflated to the recommended pressure listed on the door jamb sticker. Underinflated tires increase rolling resistance, leading to decreased fuel economy.

Minimize unnecessary weight. Removing any non-essential items from the trunk can reduce the car’s overall weight, leading to a slight improvement in fuel economy. It’s unlikely to be drastic, but every little bit helps.
