Buick Regal uses a 9-speed automatic manual transmission. The functions of the transmission are: 1. Change the transmission ratio to meet the traction needs under different driving conditions; 2. Achieve reverse driving; 3. Interrupt the power transmission to the driving wheels when the engine starts, idles, the car shifts gears, or needs to stop for power output. Taking the 2020 Buick Regal as an example, it belongs to the mid-size car category, with body dimensions of: length 4904mm, width 1863mm, height 1461mm, wheelbase of 2829mm, and a trunk volume of 441l. The 2020 Buick Regal is equipped with a 1.5t turbocharged engine, with a maximum horsepower of 169ps, maximum power of 124kw, and maximum torque of 250nm.

I've been driving the Buick Regal for quite some time now, and it comes equipped with a 9-speed automatic transmission. The specific model I recall is the Hydra-Matic 9T50, which pairs quite smoothly with either the 1.5T or 2.0T engine. Shifts are almost imperceptible, with no jerking during city traffic jams, and on the highway, the RPM stays low, making it very fuel-efficient. The ride is quiet and comfortable. For maintenance, regular checks are necessary, typically recommending a transmission fluid change every 60,000 kilometers—just opt for the original factory fluid to prevent minor issues like leaks or unusual noises. I once tested it on a long-distance trip, and the transmission responded quickly with ample power, significantly enhancing the overall driving experience. It offers great value for money, excellent durability, and peace of mind for long-term use without major issues, making it particularly suitable for office workers or family use. Occasional overtaking is no problem at all—handling is easy, the steering wheel is responsive, and everything is well-coordinated. It's fuel-efficient and just a joy to drive, with spacious and highly comfortable interiors. Overall, it's a reliable choice worth owning long-term. Avoiding aggressive driving can extend its lifespan, and after several years, it generally requires no major repairs, making upkeep a breeze.

As a car enthusiast, I'm particularly interested in the transmission details of the Buick Regal. It uses GM's 9AT, specifically the Hydra-Matic 9T50. This transmission features 9 gears with a wide gear ratio range, delivering excellent fuel economy. Actual tests show about 10% lower fuel consumption compared to older models. It provides linear acceleration, quick response, and works efficiently even with smaller displacement engines. The shifting logic is intelligent, offering smooth transitions. Early versions might have had slight delays, but the newer models have been optimized for much smoother operation. It's highly reliable, and for maintenance, it's recommended to use specialized fluids and regularly check the control system. Long-term use shows minimal issues. The overall performance is well-balanced, making it ideal for daily driving while enhancing the driving experience. The space design is practical, with a large trunk, making it comfortable and hassle-free for long trips. It's also convenient for occasional hauling, demonstrating strong practicality. Maintenance costs are reasonable, and the 4S service is attentive, making ownership simple and worry-free. Overall, it's a great car with excellent driving feel, worth considering for its high value for money. It's easy to get used to, and after driving it for a while, it becomes even smoother.

Looking back, the Buick Regal's transmission has undergone significant changes. Early versions might have used a 6AT with slow shifting and high fuel consumption. However, in recent years, it has been upgraded to a 9AT, offering smoother, quieter, and more comfortable driving. There is no noticeable jerkiness in daily driving, and it is fuel-efficient on highways with good reliability and simple maintenance. The 4S service recommends regular oil changes to avoid long-term high-temperature damage. Overall, it is highly durable, suitable for family use, and provides an excellent comprehensive experience. It rarely develops issues even after several years of use, and simple maintenance is all it takes to keep it running well.
