The fourth-generation Buick Regal puts comfort at the heart of its sedan appeal. Your choice of engine matters most when matching the car to everyday commuting and longer journeys.
Buick Regal engine options include the 2.2 AT, 2.5 AT and 3.0 AT examples, all combining gasoline power with an automatic transmission and front-wheel drive. The automatic handles gear changes for you. When choosing between engines, assess their response during overtaking and hill climbs alongside fuel consumption.
