What are the differences between the dual-clutch transmission and automatic transmission in the Excelle?

[StMiguel]

The differences between the dual-clutch transmission and automatic transmission in the Excelle are as follows: The dual-clutch is one type of automatic transmission implementation, with other automatic transmission implementations including planetary gear type, CVT continuously variable transmission, parallel shaft type, and mechanical automatic transmission. Taking the 2021 Excelle as an example, it belongs to the compact car category, with body dimensions of: length 4609mm, width 1798mm, height 1464mm, a wheelbase of 2640mm, a fuel tank capacity of 44L, and a curb weight of 1270kg. The 2021 Excelle features a MacPherson independent front suspension and a multi-link independent rear suspension. It is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 113PS, a maximum power of 83kW, and a maximum torque of 141Nm, paired with a 6-speed automatic manual transmission.

The difference between the dual-clutch transmission (DCT) and the automatic transmission in the Excelle is quite significant. I've driven models with both transmissions, and what impressed me most was the driving experience. The DCT has two clutches—one for odd gears and one for even gears—resulting in very fast gear shifts, giving a smooth, race-car-like feel, especially during high-speed acceleration, with quicker response and slightly lower fuel consumption. However, at low speeds, such as in traffic jams, there can occasionally be a slight jerk, as if the engine gives a tiny shudder. The automatic transmission, on the other hand, uses a torque converter structure, providing smooth and comfortable gear shifts, making it ideal for city commuting, though it consumes a bit more fuel. In the newer Excelle models, the DCT is more commonly found in sportier versions, while the automatic transmission is standard in base models. In terms of maintenance, if the DCT has issues, repairs can be more expensive due to its more intricate components, whereas the automatic transmission is cheaper to maintain, requiring only regular oil changes. Overall, the DCT suits those who prioritize efficiency and driving excitement, while the automatic transmission is better for those who prefer stability.

As a car enthusiast, I often compare transmission performance. The difference between the Buick Excelle's dual-clutch and automatic transmissions is reflected in operational efficiency. The dual-clutch design, through pre-shifting, delivers more direct power output, offering a manual-like agile feel with smooth acceleration and fuel efficiency; however, it can feel a bit jerky in frequent start-stop traffic. The automatic transmission is different, using traditional gear sets for smooth, barely noticeable shifts, making it more suitable for daily commuting, albeit with slightly higher fuel consumption. In the actual Excelle models, the dual-clutch version is usually positioned as more premium with faster response; the automatic transmission focuses on comfort and reliability. If you prefer a sporty feel, the dual-clutch is the better choice; if you prioritize hassle-free driving, the automatic is the safer bet. Don't forget, the dual-clutch excels on long trips, saving significant fuel costs; the automatic is simpler to maintain and has a longer lifespan.

I've been using the Buick Excelle with a dual-clutch transmission for several months now, and the main differences compared to the previous automatic version lie in smoothness and fuel efficiency. The dual-clutch shifts quickly, rarely dragging its feet, especially making starts and overtaking crisp and fuel-efficient; however, it has one issue—it's prone to slight tremors when moving at low speeds, giving a sense of instability. The automatic transmission is much smoother, stable no matter how you drive, at the cost of higher fuel consumption. The Excelle's dual-clutch requires more meticulous maintenance, with more frequent checks needed; the automatic only needs regular oil changes. If you're a beginner or mostly drive in the city, the automatic is simpler and more reliable; if you're after fuel economy, the dual-clutch offers better value.
