The 2017 Buick Cascada, equipped with its 1.6L turbocharged four-cylinder engine, offers an estimated 23 MPG combined. While this number might not compare to modern hybrids or compact cars, it’s important to remember that the Cascada is about affordable open-air enjoyment. This isn’t a car for fuel-sipping contests, but a stylish convertible chosen for leisurely weekend drives and daily commuting with a focus on image.

City and highway performance

The Cascada’s EPA ratings estimate 20 MPG in the city and 27 MPG on the highway. The city figure reflects the realities of stop-and-go driving, where the small turbo engine works harder because of the car’s weight. The highway number is more respectable, taking advantage of the six-speed automatic transmission to keep the engine at a lower, more efficient RPM at cruising speed. That said, don’t expect to consistently achieve 27 MPG if you’re frequently accelerating to pass or battling strong headwinds; the turbocharger will activate, and fuel consumption will increase.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2017 Buick Cascada. This assumes 15,000 miles of driving per year, with a mix of city and highway miles, using the national average fuel price at the time of calculation. Your actual fuel cost may vary based on your driving habits, local fuel prices, and the type of fuel you use. The Cascada doesn’t require premium fuel, but using it might yield a slight performance or fuel economy improvement in some cases, though probably not enough to offset the higher cost.

Real-world expectations

Cascada owners often report fuel economy figures close to the EPA estimates, but this is heavily influenced by driving style and conditions. Drivers who value fuel efficiency and drive conservatively can often achieve 25 MPG or higher on longer highway trips. However, those who enjoy occasional quick acceleration or spend most of their time in congested urban areas may see their fuel economy drop to the lower end of the EPA range or even slightly below.

How it compares

When considering the Cascada’s fuel economy, its competitors in the convertible segment should be taken into account. The now-discontinued Volkswagen Eos, for example, with its 2.0L turbo engine, was rated at 22 MPG combined. The Mazda MX-5 Miata, while smaller, offers better fuel economy, achieving around 30 MPG combined, which shows the benefits of lighter weight and a naturally aspirated engine. A newer convertible option like the Mini Cooper Convertible manages around 28 MPG combined. For more in-depth information on CASCADA MPG across all years, this site offers specific data. The Cascada buyer is often less focused on ultimate fuel efficiency and more appreciative of the combination of style, affordability, and a comfortable, practical convertible experience given the alternatives.

Tips to maximize efficiency

Maintaining proper tire inflation is a simple way to improve fuel economy. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the sticker located on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel efficiency.

Avoid excessive idling. If you’re stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine and restart it when you’re ready to go. The Cascada’s engine restarts quickly and smoothly, so there’s no need to keep it running unnecessarily.

Use cruise control on the highway to maintain a consistent speed and avoid unnecessary acceleration and braking. This can help you achieve the best possible fuel economy during long drives. Be mindful of traffic conditions and disengage cruise control when needed.

Minimize the use of accessories like air conditioning and heated seats, as they can strain the engine and reduce fuel economy. When possible, open the windows or put the top down instead of using the AC. Minimize the amount of extra weight in the vehicle, too.
