What is a Direct Shift Gearbox (DSG)?

What is a DSG Gearbox?

There are different kinds of gearbox options available in vehicles these days. While the manual and automatic gearbox options are well-known, a newer option called the direct shift gearbox (DSG) has now emerged. Here, the clutching system is automated and works to release the appropriate gears as the car moves.

How Does a Direct Shift Gearbox Work?

Now that you know what is a direct shift gearbox, let us understand how it works. There are two clutches, each responsible for the odd (1st, 3rd, 5th) and even (2nd, 4th, 6th) gears. While one works, the other clutch prepares the remaining set of gears for use. This results in quick and smooth gear changes that increase the efficiency of the vehicle.

Pros of Direct-Shift Gearbox

1. Very fast -

The DSG direct shift gearbox system leads to a lightning-fast gear shift while the vehicle is moving and this adds to the driving experience.

2. Completely automatic -

The system is completely automatic and that reduces the stress on the driver and the vehicle as well.

3. Fuel efficient -

Gear ratio optimisation happens in the direct shift gearbox system. This leads to total fuel efficiency and you see a significant change in the car’s mileage.

Cons of Direct-Shift Gearbox

1. Shorter lifespan -

Due to constant engagement, the DSG clutches experience wear and tear at a faster pace. Consequently, the entire system has a lower lifespan as compared to a traditional gear system.

2. High maintenance -

You require very precise and advanced maintenance for this technologically refined gear system.

3. More expensive -

The components of the gearbox are expensive and you may have to spend more during repairs. Your standard car insurance policy may not cover all the repairs, so explore the add-on covers to maximise coverage.

Comparison of DSG Gearbox with Manual & Automatic Transmission

When compared to the traditional manual and automatic gearbox systems, the DSG system has its advantages and disadvantages. While on one hand, it increases the performance and fuel efficiency of the car, on the other, it increases the cost. It is also a very new concept for Indian drivers who have, over the years, been accustomed to manual systems. The direct shift gearbox system is a very good initiative and with time, will surely gain more prominence in India.

FAQs

2. Is the direct shift gearbox system covered in a car insurance plan?
