What is the fuel consumption of the 2009 Buick Regal?
2 Answers
The 2009 Buick Regal has a total of 6 models. Among them, the 2009-1.6T-Elite Sport version is equipped with a 179 horsepower engine, with an NEDC fuel consumption of 7.9L per 100km. The 2009-2.0L-Elite and Comfort versions, both equipped with a 147 horsepower engine, have an NEDC fuel consumption of 8.8L per 100km. The 2009-2.4L-Flagship and Elite versions, both equipped with a 170 horsepower engine, have an NEDC fuel consumption of 9L per 100km. The 2009-2.0T-Luxury Sport version, equipped with a 220 horsepower engine, has an NEDC fuel consumption of 9.6L per 100km. The 2009 Buick Regal has a fuel tank capacity of 70L. The distance each model can travel on a full tank of fuel is as follows: Models equipped with a 179 horsepower engine can travel 70/7.9*100=886km on a full tank. Models equipped with a 147 horsepower engine can travel 70/8.8*100=795km on a full tank. Models equipped with a 170 horsepower engine can travel 70/9*100=777km on a full tank. Models equipped with a 220 horsepower engine can travel 70/9.6*100=729km on a full tank. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacement generally consume more fuel than those with smaller displacement because larger displacement usually means higher power, requiring more gasoline for combustion. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperature: When the engine block is cold, the injected gasoline is less likely to vaporize during a cold start, requiring more gasoline to combust, thus increasing fuel consumption. Additionally, in low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, which also increases fuel consumption.
I drove a 2009 Buick Regal with a 2.4L engine for a while, and it typically consumed around 13-15 liters per 100km in city commuting. During rush hour traffic jams, the instantaneous fuel consumption could spike to 18 liters, but it was more economical on highway cruising, averaging about 8-9 liters. The car weighs nearly 1.6 tons, coupled with an old 6AT transmission, so it's not exactly fuel-efficient. I usually try to avoid congested routes, maintain steady speeds, and regularly clean throttle valve carbon deposits to slightly improve the situation. After all, it's a decade-old car, so higher fuel consumption is normal—the key is to invest in proper maintenance.
