Is the Buick Regal Fuel Consumption High?

[DelClayton]

Buick Regal itself has a large curb weight, so its fuel consumption is relatively higher, but it is also recognized as a highly safe vehicle. Starting from the Regal 2.5V6, fuel consumption is no longer a major issue for the Regal. Actual fuel consumption of the Buick Regal: The fuel consumption of the Buick Regal ranges from 4.3L to 10.2L. Actual fuel consumption is related to factors such as vehicle condition and road conditions, and there is no specific value. Methods for calculating fuel consumption: There are two methods to calculate a vehicle's fuel consumption: The first method involves resetting the mileage data on the vehicle's dashboard, after which the onboard computer automatically calculates the fuel consumption based on the recorded mileage and fuel consumption data. The second method involves recording the mileage traveled after a single refueling and then calculating the vehicle's fuel consumption. The fuel consumption obtained by both methods is the average fuel consumption of the vehicle.

I've been driving a Buick Regal for half a year now, let me share my real fuel consumption experience. As a daily commuter family car, it does consume quite a bit of fuel in city traffic jams, usually hovering around 10-12 liters per 100km, and I've recorded up to 14 liters when there are many traffic lights. However, it performs decently on highways with a steady 7-8 liters. Japanese cars with the same displacement generally consume 1-2 liters less, but the Regal's solid chassis provides stable handling and good sound insulation, which makes the difference acceptable to me. If you have a heavy foot on the accelerator or frequently drive uphill, the fuel consumption will be even higher. Actually, developing habits like anticipating road conditions and avoiding sudden braking can save you a lot on fuel costs.

When it comes to the Regal's fuel consumption, it really depends on how you compare. The 2.0T version with 245 horsepower delivers thrilling acceleration, but the trade-off is noticeably faster fuel consumption – it easily starts at 11L/100km in city driving with AC on. However, the 1.5T version is much more economical, with real-world combined consumption around 9L/100km. The new 9AT transmission is quite intelligent, offering 15% better fuel efficiency than the old 6AT. Last week, I specifically tested it at a steady 60km/h on the ring road, and the display showed only 5.8L/100km. My personal suggestion is not to focus solely on the numbers – this car comes standard with ANC active noise cancellation and aluminum suspension, which offer more substantial features than some Japanese cars in the same price range.

The fuel consumption of the Regal varies depending on the scenario. As a long-time owner, I've conducted real-world tests: with the AC on in 34°C heat while driving in the city, the display showed 12.3L; on overcast days with the AC off while driving on elevated roads, it was 7.2L. The driving mode has the biggest impact—sport mode consumes 1.5L more than normal mode. If you frequently drive fully loaded or uphill, I recommend opting for the 2.0T version with cylinder deactivation technology, which automatically switches to four cylinders during highway cruising for significant fuel savings. In fact, fuel efficiency is no longer a weakness for American cars. The current model's lightweight design brings it down to 1.5 tons, which is 50kg lighter than my friend's Passat.

Just helped a relative pick out a new Regal and thoroughly researched its fuel consumption. The key lies in the engine model: the 652T 2.0T engine consumes 10-11L/100km in city driving, while the 552T 1.5T averages around 9L/100km. Special reminder for northern drivers: fuel consumption spikes during cold starts in winter—it's best to use 0W-20 full synthetic oil. I compared it with the LaCrosse hybrid version, which saves 3L/100km over the gasoline model, but unfortunately, the Regal doesn't offer a hybrid variant. However, dealerships now offer a lifetime engine warranty policy, so higher fuel consumption doesn't necessarily mean worrying about maintenance costs.
