Automatic transmission (automatic transmission) and dual clutch transmission (DSG) are the two main types of automatic transmissions used in modern cars. The main differences between them are as follows:
Design:
* Automatic transmission: Has a torque converter, which serves to transfer power from the engine to the gearbox smoothly.
* DSG: Has two clutches: one for odd gears and the other for even gears. This ensures faster gear changes.
Gear shift:
* Automatic transmission: Shifts gears smoothly, without noticeable jerks.
* DSG: Shifts gears very quickly, which can result in noticeable jerkiness, especially at low speeds.
Efficiency:
* Automatic transmission: Typically less efficient than DSG due to power loss in the torque converter.
* DSG: More efficient because it uses two clutches and does not have a torque converter.
Reliability:
* Automatic transmission: Generally more reliable than DSG, especially at high mileage and in difficult operating conditions.
* DSG: More sensitive to clutch wear and problems with mechatronics (electronic control unit).
Service:
* Automatic transmission: Requires regular oil and filter changes.
* DSG: Also requires regular oil and filter changes, but usually less frequently than automatic transmissions.
Application:
* Automatic Transmission: Widely used in many types of vehicles, including cars, SUVs and trucks.
* DSG: Often used in sports cars and high-performance models due to its quick gear changes.
Price:
* Automatic: Typically cheaper to produce than DSG.
* DSG: More expensive due to its complex design.
Generally:
* Automatic transmission provides a smoother and more comfortable ride, but is less efficient and may be less reliable than DSG.
* DSG provides faster and sharper gear changes, which improves efficiency and performance, but it can be less reliable and more expensive to maintain.
