A Dual Clutch Transmission can be regarded as a hybrid gear and works a little like a manual and an automatic combined. These gearboxes are usually fully automatic, but can also be manually shifted using the steering wheel paddles. A simple way of describing its operation is that it is an automatically operated manual transmission which is achieved by using two clutches. The beauty of this type of gear unlike manual and automatic is that it features lightning-quick gear shifts. These gearboxes are currently found mostly in racing cars, high-end sports cars, and high-performance vehicles. We will take a closer look at this transmission and its advantages and disadvantages.
Advantages
- The goal of a DCT is to keep the gap between gear shifts as small as possible, resulting in enhanced performance and fuel efficiency.
- The less time spent off the power changing gear during acceleration, the faster the car can accelerate – and the less time spent off the power during gear changes in general, the greater fuel efficiency the vehicle will have because engine power will not be lost.
- DCT gear changes may now be timed in milliseconds, faster than any driver can shift a gear, while yet maintaining the advantages of a manual gearbox over an automated.
- It accomplishes these lightning-fast shifts by anticipating the next gear required depending on criteria including rate of acceleration or deceleration, current speed of travel, and engine speed. This allows the computer to automatically engage the predicted gear before the shift is made.
- It is a portable transmission, light weight and easy to install.
Disadvantages
- It is an expensive transmission.
- When driving from a stop to a very slow pace, it frequently encounters issues, such as a delay in entering first gear as the driver continues to depress the accelerator in anticipation of power delivery. Once the system has caught up and the gear is engaged, the car will accelerate in accordance with the engine speed, and if the driver has given it too much power, the car may unexpectedly surge ahead.
- Advances in automatic gearbox technology have narrowed the gap between them and DCTs, and with automatics already outselling manuals in growing numbers, we may soon witness a period when manual transmissions are phased out entirely, leaving only aficionados with them.
Continuous refinement and improvement, like any system, eliminates problems and enhances operation, and this may be the case here provided the development time is granted. However, the writing on the wall may already be on the wall, as some automakers have questioned the viability of complex transmissions.
