Is the Envision 1.5 Dual Clutch Dry Type?
3 Answers
The Envision 1.5T transmission is a 7-speed dry dual clutch. Introduction to Dry Clutch: A clutch cooled by air is called a dry clutch. In use, the clutch must engage and disengage from the power smoothly and easily, and should not overheat even when operating under semi-engaged conditions for short periods. Dry clutches, because they lack the resistance of oil, generally have faster engagement responses and slightly greater engagement force. Also, due to the absence of oil cooling, dry clutches are usually exposed to dissipate heat. Introduction to Wet Clutch: A clutch cooled by oil is called a wet clutch. The cooling oil does not protect the friction plates but ensures smooth and gentle power transmission. Its advantages include a long service life and generally trouble-free operation, unless operating procedures are violated by frequently keeping the clutch in a semi-engaged state. Wet clutches are mostly used in automatic transmissions, such as the now commonly used manual-automatic integrated transmissions. They engage by pressing multiple steel plates and friction plates together through the action of a hydraulic cylinder and disengage when the oil returns under the force of springs.
I've been driving the Buick Envision 1.5T model for almost two years, and its dual-clutch transmission is indeed the dry type. When I was choosing the car, I carefully compared and found that this transmission occasionally has slight jerks during frequent start-stop in the city, especially noticeable in traffic jams. The advantages lie in its quick response, fast gear shifting, and high fuel efficiency, with average fuel consumption controlled at around 7 liters. As someone who often takes long trips, I find its highway performance very stable, but beginners might not adapt to the instant gear-shifting feeling. It's important to note that dry clutches are prone to problems in high-temperature environments. I recommend maintaining good vehicle condition and avoiding prolonged low-speed driving to extend its lifespan. Overall, you'll get used to it after driving for a while.
As a car enthusiast, I have a deep understanding of the Buick Envision's configurations. The 1.5L version uses a dry-type dual-clutch transmission. This means it lacks an oil cooling system and relies on dry friction plates for operation, providing direct gear shifts but potentially heating up in traffic jams. Compared to wet-type dual-clutch transmissions, it is lighter, has lower maintenance costs, but slightly inferior durability, especially in urban environments. During my test drive, I found the power delivery crisp and acceleration swift, making it suitable for those who enjoy a sporty feel. For occasional long-distance trips, it performs well, though it's advisable to regularly inspect the drivetrain components to prevent unexpected damage.
