Why does the Tucson use a dry dual-clutch transmission?
2 Answers
Tucson uses a dry dual-clutch transmission because of its simple structure and low cost. The advantages of a dual-clutch transmission include the following: Fast shifting: The shifting time of a dual-clutch transmission is very short, even faster than a manual transmission, taking less than 0.2 seconds. Fuel efficiency: The dual-clutch transmission eliminates torque interruption, meaning the engine's power is continuously utilized and always operates at its optimal level, resulting in significant fuel savings. Compared to traditional planetary gear automatic transmissions, it is more conducive to improving fuel economy, with fuel consumption reduced by approximately 15%. Comfort: Due to the fast shifting speed, each shift of the DCT is very smooth, with the jerkiness minimized to a level that is hardly noticeable to the human body.
Hyundai equipped the Tucson with a dry dual-clutch transmission primarily for fuel and cost savings. This thing boasts about 7% higher transmission efficiency compared to AT gearboxes, especially noticeable on highways where it burns less fuel. The dry design is simpler and nearly 20kg lighter than wet versions, lowering overall vehicle costs—ultimately making the car cheaper for buyers. Of course, manufacturers also addressed cooling: newer models feature upgraded clutch materials and smarter shift logic, preventing overheating in normal city driving. But for daily mountain routes or long steep slopes, wet clutches do handle abuse better.
