DCT vs CVT: Which Gearbox is Better?

One of the major factors that affect your driving experience is the kind of gearbox present in your car. While there are broadly two types of transmissions - manual (MT) and automatic (AT), the latter has multiple sub-categories. Two popular and prominent types of AT include the Dual Clutch Transmission (DCT) and the Continuously Variable Transmission (CVT). Each comes with its own set of merits and demerits, making the decision to choose between them a difficult one. Let’s take a look at DCT and CVT gearboxes in detail, exploring their functioning, merits, demerits, cost considerations, maintenance requirements, and more.

What is a DCT Gearbox?

First, let’s understand what DCT is and how it works:

1. A Dual Clutch Transmission (DCT) is a newer, more advanced form of AT that requires the working of two separate clutches to allow for gear shifts.
2. What makes DCT distinct from the rest of ATs is the fact that while one clutch engages one gear, the other pre-selects the next gear. This can smoothen the shifts between gear shifts to a great extent.
3. The DCT gearbox is popular in sports cars and high-performance vehicles due to its high-speed gearshifts. However, its complexity and high cost can mean that it suits only certain car types and drivers.
4. Currently, some of the cost-effective DCT cars available in India include the Tata Altroz, Hyundai Venue, Hyundai i10, and Kia Sonet.

What is a CVT Gearbox?

Now, let’s briefly read through how a CVT gearbox works:

1. Continuously Variable Transmission (CVT) is also an advanced type of AT. CVT makes use of a belt and pulley system to continually change the gear ratio, leading to a smooth driving experience.
2. CVTs are considered fuel-efficient, outperforming conventional transmissions.
3. While its fuel efficiency is a considerable benefit, a CVT gearbox may not be as responsive as a DCT. Hence, they may not be ideal for high-performance vehicles.
4. When it comes to cost-effective CVT cars, the Honda Amaze, Renault Kiger, Nissan Magnite, and Honda Jazz are some well-known options.

DCT vs CVT: Performance

Let’s see how DCTs and CVTs fare against each other in the following key aspects:

Performance of the gearbox

When it comes to performance, DCT gearshift time is known for being lightning-fast. Hence, it is usually found in high-performance and sports cars. On the other hand, CVT performance is characterised by a seamless driving experience. Accordingly, it is commonly used for mainstream vehicles.

Fuel efficiency and responsiveness

Regarding efficiency, DCT’s mileage is considered slightly lower. However, it has impressive responsiveness. Alternately, while CVT offers higher fuel efficiency, it may lag behind DCT in responsiveness.

Cost and affordability 

When it comes to costs, DCTs tend to be on the higher side. They are expensive to manufacture, and hence, they can be costly to maintain as well. On the other hand, CVTs generally come with a lower price tag, even though the actual cost can vary based on the make and model of the vehicle.

Maintenance requirements

Both DCT and CVT gearboxes need regular maintenance and care. However, despite one’s best efforts, wear and tear are potential concerns for both transmissions. DCTs may be a bit more difficult to maintain since they tend to be more complex. Thus, when it comes to choosing between DCT and CVT, the answer may depend on individual preferences and needs. If you want a smooth and efficient driving experience, then CVT might be the better option. But if high-speed gear shifts and better gearbox response are what you are looking for, DCT might be the more fitting choice. Regardless of which type of transmission you choose, it is important to secure your car and its components with a vehicle insurance policy. With the right kind of car insurance coverage, you can get financial protection for the gearbox as well.* Claims are subject to terms and conditions set forth under motor insurance policy.

Car Insurance - Financial Protection for Gearbox and Other Components

Here are some ways a car insurance plan can benefit you.

Protection from accidents*

As per prevailing laws, vehicle owners must have relevant third-party car and bike insurance . If you opt for a comprehensive plan, you get protection from third-party liabilities as well as high-quality repairs for damages to your car in case of an accident.

Protection for various components*

By opting for add-ons such as the engine protector add-on, you can enhance the vehicle insurance plan’s overall protection. This add-on provides coverage to the car’s engine, gearbox, and gearbox parts against water ingression, oil leakage, hydrostatic lock, and so on.

All-round coverage against various events*

Whether it is a natural disaster like an earthquake, tsunami, flood, or a manmade calamity like riots or theft, damage to your car due to these events is covered.
