When one is considering purchasing a new car, probably one of the important decisions is to choose between either a CVT or an automatic transmission. The debate between CVT vs. automatic transmissions can get rather confusing right from the word go, but with a clear understanding of the differences, one will be able to make an appropriate choice. Even though both types of transmissions offer different benefits and features, they work in very diverse ways.
In this guide, we’ll closely examine what makes CVT and automatic transmissions tick so that you know which suits your style and needs. So, let’s get into the world of car transmissions to learn these basic differences!
What is CVT and How Does it Work?
Continuously Variable Transmission is a type of transmission that has no set number of gears like in the normal automatic transmission but uses a belt and pulley system. This system enables the CVT to shift smoothly through the entire band of gear proportions, corresponding to the preferred engine speed in any condition of control.
To understand how it works, think about riding a bicycle with gears: CVT works differently, where it slips continuously rather than having set gears, so there is almost no gear shifting; it makes drives smoother as well as more fuel efficient compared to automatics.
Key Differences: CVT vs. Automatic Transmission
Here are the major areas of interest:
Gear System
- CVT: No fixed gears, but uses a system of belt and pulley.
- Automatic Transmission: Have a fixed number of gears.
Driving Experience
- CVT: Smooth and seamless.
- Automatic Gearbox: The gears noticeably change clearly, and it provides a more traditional feel when driving.
Fuel Efficiency
- CVT: Mostly fuel-efficient since it operates while the engine is at its peak level.
Automatic Gearbox: May consume more fuel since it operates mostly on stop-and-go traffic.
Performance - CVT: Lacks some performance or control according to some drivers.
Automatic Transmission: Most drivers who would like to have much better responsiveness and control prefer using this.
Maintenance and Durability
- CVT: Known for having specific maintenance needs and can be more expensive to repair.
- Automatic Transmission: It is generally more robust and easier to maintain in the long term.
Advantages of Automatic Transmissions
- Better Driving Experience: The automatic gearbox gives the driver a better experience. You can feel the upshifts and downshifts, offering a connected feeling to the vehicle. This is helpful, especially in large SUVs or off-road vehicles.
- Repair Costs: Conventional automatic gearboxes are usually much cheaper to repair. The gears are easily replaced, and the mechanism is definitely less complicated than that of stepless transmissions.
Disadvantages
- More Emissions: Automatic gearbox can be less eco-friendly. Limited gear ratios mean the engine may not always run at optimal efficiency, leading to higher emissions.
- Lower Fuel Efficiency: In comparison to stepless variable gearboxes, automatics may prove to be less efficient due to their fixed gear ratios that don’t constantly coordinate with optimal power needs.
Advantages of Continuously Variable Transmission
- Smoother Operation: It offers smooth and unnoticeable gear shifts. This results in much less movement in the cabin and, hence, more comfortable for long drives.
- More Economical to Run: Most stepless transmissions provide better gas mileage. They can run at the best RPM or revolutions per minute for whatever the driving condition, thus saving fuel and limiting wear on the engine.
Disadvantages
- Expensive to Repair: Continuously variable transmission is costly to repair. It is relatively more complicated compared to the rest of the types of gearboxes and can only be repaired by a technician experienced with such gearboxes, which is hefty to repair.
- Noisy: Some models of stepless variable transmission produce droning sounds when used at high speeds. This constant noise can be irritating on long drives.
Common CVT Transmission Problems
- Belt Wear: The belt in a stepless transmission can wear down faster as compared to the gears in a normal automatic gearbox.
- Overheating: The stepless transmission may overheat, especially if it is loaded heavily or while being driven aggressively.
- Noise: Many drivers report CVTs to be noisier compared to normal automatics.
Conclusion
Choosing between CVT vs. automatic transmission depends on your priorities. If you want smooth driving and better fuel efficiency, CVT might be best. If you prefer a classic driving feel and lower repair costs, an auto transmission could be the way to go.
