20 MPG combined isn’t thrifty, but for a 2016 Porsche 911 Turbo S Cabriolet, it’s an acceptable trade-off for performance. This all-wheel-drive convertible has 560 horsepower and can reach 60 mph in under three seconds. This isn’t basic transportation; it’s a statement, an experience, an engineering masterpiece designed for driving pleasure. Buyers probably aren’t worried about gas prices; they’re buying an automotive icon, and fuel consumption is part of owning it.

City and highway performance

The EPA estimates the 2016 911 Turbo S Cabriolet gets 17 MPG in the city and 24 MPG on the highway. The city number reflects stop-and-go traffic, where the engine is constantly working. The highway number is better, thanks to the seven-speed PDK transmission choosing higher gears for efficient cruising. Even on the open road, resisting the urge to accelerate with the turbocharged flat-six will be difficult. Maintaining speed and avoiding quick overtaking will help achieve the rated 24 MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Porsche 911 Turbo S Cabriolet is $2,900. This is figured from 15,000 miles per year, with 45% in the city and 55% on the highway. It also assumes premium fuel, which is required. This $2,900 estimate is based on national average fuel prices – your actual costs will depend on your location and driving style. Because this is a high-performance model, expect to stop at the pump more often than a typical sedan driver.

Real-world expectations

The EPA provides a standard, but real-world fuel economy can vary. Aggressive driving, short trips, and bad weather will hurt fuel consumption. Owners who regularly use the Turbo S Cabriolet’s power will likely see numbers closer to the city rating, even in mixed driving. On the other hand, those who prioritize fuel efficiency and drive more calmly might get closer to the highway rating. Buying a car like this and obsessing over fuel economy is like buying a racehorse and not letting it run.

How it compares

The 911 Turbo S Cabriolet’s fuel economy is similar to other high-performance convertibles. A 2016 Audi R8 V10 Spyder, with its naturally aspirated engine, gets a similar 16 MPG city and 23 MPG highway. More exotic cars, like a Ferrari 488 Spider, get around 15 MPG city and 22 MPG highway. Porsche fuel economy data shows that extracting 560 hp from a 3.8-liter engine has consequences. These comparisons show that performance has a price, and for those wanting open-air driving, fuel efficiency isn’t usually the main concern. You can also see 911 MPG across all years, showing how efficiency has changed in this sports car.

Tips to maximize efficiency

Fuel economy might not be the top priority for a 911 Turbo S Cabriolet owner, but there are ways to minimize consumption while still having fun. Avoid fast acceleration and braking when you can. The Turbo S’s power is addictive, but gentle throttle inputs will reduce fuel consumption.

Use Sport or Sport Plus modes sparingly. These modes sharpen throttle response and hold gears longer, but they also increase fuel consumption. The standard driving mode balances performance and efficiency for everyday driving.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and consume more fuel. Check your tire pressures regularly and keep them at the recommended levels.

Remove any unnecessary weight from the vehicle. Extra weight adds to the car’s load, reducing fuel economy. Leave those golf clubs at home unless you’re going to the course.
