What's the difference between GS4's dual-clutch and 6AT transmissions?
2 Answers
In terms of technology and structure, the AT (automatic transmission) is the most mature automatic transmission, with an earlier development history compared to dual-clutch transmissions. The 6AT transmission, especially the Aisin 6AT, is often referred to as the "best transmission" in the market. Below is more information about dual-clutch and 6AT transmissions: 1. Automotive transmissions can be divided into manual transmissions and automatic transmissions. The AT is what is commonly known as an automatic transmission, with gear positions including P, R, N, D, 2, 1, or L. The 6AT indicates six forward gears, meaning there are six sets of gear groups with different transmission ratios. Others include 4AT, 8AT, 9AT, and even 10AT. Although the numbers differ, they are all derivatives of automatic transmission technology. 2. A dual-clutch transmission, simply put, has two sets of clutches working simultaneously—one manages the odd-numbered gears, while the other manages the even-numbered gears. This design aims to avoid the power interruption issue during gear shifts in traditional manual transmissions, achieving faster gear changes.
I think the choice between the dual-clutch and 6-speed automatic transmission for the GS4 really depends on personal needs. The dual-clutch shifts exceptionally fast, providing smooth acceleration and fuel efficiency during highway driving or aggressive maneuvers, but it can feel jerky in stop-and-go city traffic and is prone to overheating issues. The 6AT is much smoother, highly durable, and performs steadily in almost all road conditions, though its fuel consumption is slightly higher than the dual-clutch. It feels more suitable for daily commuting. Having driven both versions, I found the GS4 with the dual-clutch offers agile handling but higher maintenance costs—replacing a clutch plate can cost thousands, while the 6AT only requires basic upkeep, saving both money and hassle. If you enjoy strong acceleration and low fuel consumption, try the dual-clutch; if you prioritize stability and fewer repairs, the 6AT is definitely reliable.
