2016 Porsche Boxster GTS Fuel Economy: What to Expect

25 MPG combined isn’t going to win any green car awards, but it’s perfectly acceptable for the 2016 Porsche Boxster GTS. This figure represents balanced performance: enough efficiency to avoid guzzler taxes, paired with the naturally aspirated flat-six thrill that defines the GTS experience. This isn’t basic transportation; it’s an experience, and buyers of the Boxster GTS understand that trade-off. They’re not prioritizing hypermiling; they’re prioritizing the sound, the responsiveness, and the sheer joy of driving a perfectly balanced, mid-engine roadster.

City and highway performance

The EPA estimates the 2016 Porsche Boxster GTS achieves 21 MPG in the city and 30 MPG on the highway. The city figure reflects the nature of urban driving: stop-and-go traffic and frequent acceleration that puts a strain on fuel consumption. The highway number is more indicative of the engine’s efficiency at a steady cruise, where the 3.4L flat-six can settle into its most efficient operating range. These numbers assume a reasonable driving style, of course, but even a spirited driver should see numbers close to these, as the PDK transmission is programmed to upshift quickly to higher gears when appropriate.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Porsche Boxster GTS at $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that premium fuel is required for optimal performance, and prices fluctuate, thus impacting real-world costs. Owners report that they find this figure to be lower than initially suggested, because Boxster GTS owners generally don’t put 15,000 miles on their car every year. They tend to be weekend cars, toys, or vehicles used during the warmer months.

Real-world expectations

While the EPA provides a baseline, real-world fuel economy depends heavily on driving habits. Expect lower numbers with frequent track days or aggressive canyon carving. Conversely, a driver who prioritizes smooth acceleration and consistent highway speeds might see slightly better numbers. The temptation to explore the upper reaches of the tachometer is strong with the Boxster GTS, and frequent visits to the redline will certainly diminish fuel economy. Remember that this car rewards spirited driving, and the occasional indulgence comes at the expense of efficiency. See all all Porsche fuel economy data here.

How it compares

In the realm of performance roadsters, the 2016 Porsche Boxster GTS sits in a competitive field. A comparable BMW Z4 M40i delivers around 25 MPG combined. The difference comes down to priorities. The Boxster GTS emphasizes pure driving feel, while the Z4 provides a slightly more luxurious experience. A Jaguar F-Type with its V6 engine manages around 23 MPG combined, illustrating the fuel-economy penalty of a larger displacement engine. The Alfa Romeo 4C Spider achieves around 28 MPG combined, but its focus on minimalism sacrifices some of the Boxster’s refinement. Each vehicle presents its own unique pros and cons. Be sure to view all BOXSTER MPG across all years to see the progression of this vehicle and model’s fuel mileage across the years.

Tips to maximize efficiency

Avoid short trips. Cold starts consume a significant amount of fuel as the engine works to reach its optimal operating temperature. Combining errands into longer driving routes can lessen the impact of cold starts, improving overall fuel economy.

Monitor tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and waste fuel. The Boxster GTS has a tire pressure monitoring system. Keeping your tires properly inflated not only improves efficiency but also enhances handling and safety.

Use the PDK transmission’s automatic mode when cruising. The PDK (Porsche Doppelkupplungsgetriebe) transmission is remarkably intelligent, and its automatic mode is surprisingly adept at selecting the most efficient gear for the situation. You shouldn’t be afraid to use it instead of always shifting yourself.

Anticipate traffic flow. By looking ahead and anticipating changes in traffic speed, you can minimize unnecessary braking and acceleration. Smooth, consistent driving is the key to maximizing fuel efficiency, especially on the highway. Let other drivers go first off the line, you’ll ultimately save fuel.
