The performance of dual-clutch transmissions (DCT) in long-term use requires comprehensive evaluation based on their technical characteristics and usage scenarios. DCT achieves rapid gear shifts through the alternating operation of two clutch sets, offering high transmission efficiency and minimal power loss. It is ideal for drivers seeking enhanced performance or frequent high-speed operation, with shift speeds approaching those of manual transmissions to deliver more immediate acceleration. However, in stop-and-go urban traffic, repeated starts and stops may lead to clutch plate overheating-particularly in dry DCT systems-where prolonged partial engagement accelerates wear. Regular maintenance (such as clutch clearance inspection every 60,000 kilometres) is essential to prevent failures. By comparison, continuously variable transmissions (CVT) excel in long-term durability due to their simpler construction and seamless gear transitions. For predominantly urban commuting, CVT's smooth operation and fuel efficiency prove more practical, while DCT's power transfer efficiency better suits highway driving or performance-oriented applications. Both systems can exceed 10 years of service life when properly maintained, though DCT demands more rigorous upkeep.
