26 MPG combined is perfectly acceptable for the 2020 Buick Regal 2.0L turbo. Buick isn’t trying to be the most efficient. This car is designed for comfortable cruising, offering a plush ride and quiet cabin without sacrificing all sense of responsiveness. The Regal buyer wants value and a smooth driving experience. They aren’t hypermilers, but they also aren’t looking to spend a lot on gas every week. This MPG strikes a reasonable balance.
City and highway performance
The EPA estimates for the 2020 Regal are 22 MPG in the city and 32 MPG on the highway. That highway number is where the Regal works best, which shows how well it works for long trips. The 2.0L turbo provides enough power for merging and passing, and the nine-speed automatic transmission allows the engine to run at a low RPM at cruising speeds, maximizing fuel efficiency. City driving, with its stop-and-go nature, lowers the fuel economy. The 22 MPG rating is still good for this class of vehicle, but drivers who mostly commute in the city should remember that it will affect their overall MPG.
Annual fuel cost
The EPA estimates that the annual fuel cost for the 2020 Buick Regal 2.0L 4-cyl is $2,250. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Fuel costs will change depending on driving habits, local fuel prices, and the type of fuel used, but this is a good way for potential owners to estimate. Premium fuel is not *required* in the Regal, but using it will likely make it more responsive. If gasoline prices change a lot, this annual cost will change. For example, a 50-cent swing in the national average gas price could change the annual fuel cost by several hundred dollars.
Real-world expectations
While the EPA figures are useful, real-world MPG can change a lot. Driving fast will quickly use up the fuel, while smooth acceleration and watching traffic can push the numbers closer to the EPA’s estimates. The Regal’s nine-speed automatic generally selects the right gear, but fast acceleration can still force frequent downshifts, which hurts fuel economy. Driving style, terrain, and even weather conditions all matter. Owners who often carry passengers or cargo will also see a decrease in MPG. To get the best fuel economy you should drive mindfully and consistently.
How it compares
Several competitors have similar fuel economy, but each has some tradeoffs. The Acura TLX 2.4L, for example, gets around 28 MPG combined, but it’s not as fun to drive as the Regal. The Mazda6 with the 2.5L turbo engine offers about 26 MPG combined, but it’s sportier and might not appeal to Buick buyers who want comfort. Even the Honda Accord 1.5T models do about 33 MPG combined, but it has more mainstream styling than the Regal. The REGAL MPG across all years offers insights to the Regal’s engine options and performance. These differences show that it’s important to choose a vehicle that fits your needs and wants. The Regal is a good option for those who want luxury and comfort and look at all Buick fuel economy.
Tips to maximize efficiency
Use the Regal’s cruise control system on long highway stretches. Keeping a consistent speed improves fuel economy and reduces driver fatigue on those long road trips.
Check your tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Keep your tires inflated to improve fuel economy and extend tire life.
Avoid fast acceleration and hard braking. The Regal’s turbocharged engine responds well to smooth inputs. Watch traffic and let off the gas early to reduce the need for sudden braking. This will result in a smoother ride and improved fuel economy.
Minimize idling. If you anticipate being stopped for more than a minute or two, turn off the engine. Idling uses fuel without moving the vehicle. Modern cars restart quickly, so there’s no need to let the engine run.
Use “Tour” mode for most driving. This mode helps fuel efficiency by changing the engine and transmission settings for smooth driving. “Sport” mode offers more aggressive throttle response, but it uses more fuel, so use it when you want to enjoy the Regal’s performance.
