Infiniti, known for its luxurious and performance-oriented vehicles, has embraced the Continuously Variable Transmission (CVT) technology in its lineup․ While some associate CVTs with fuel efficiency, others question their performance and durability․ This article delves into the intricacies of Infiniti’s CVT transmissions, exploring their manufacturer, design, and the advantages and disadvantages they offer․
Who Makes Infiniti CVT Transmissions?
Infiniti, being a subsidiary of Nissan, relies on Nissan’s expertise in CVT technology for its transmissions․ Nissan has been a pioneer in CVT development, with its Jatco subsidiary specializing in the production of these transmissions for various Nissan and Infiniti models․
Infiniti CVT Design and Features⁚
Infiniti’s CVTs, like those found in other Nissan vehicles, employ a belt-and-pulley system․ The belt, made of steel or a durable synthetic material, connects two pulleys․ These pulleys, with varying diameters, regulate the gear ratio, providing a seamless and smooth power delivery throughout the rev range․
Infiniti’s CVTs are known for their smooth and efficient operation․ Unlike traditional automatic transmissions with distinct gear steps, CVTs offer a continuous flow of power, eliminating the jerky transitions that can occur during gear changes․ This smooth acceleration is particularly advantageous in city driving and for fuel economy․
Advantages of Infiniti CVTs⁚
- Enhanced Fuel Efficiency⁚ CVTs allow the engine to operate at its most efficient RPM, resulting in reduced fuel consumption․
- Smooth and Seamless Acceleration⁚ The absence of distinct gear changes translates to a smoother and more refined driving experience․
- Quiet Operation⁚ CVTs generally operate more quietly than traditional automatic transmissions․
Disadvantages of Infiniti CVTs⁚
- Engine Braking⁚ Unlike traditional automatics, CVTs don’t offer the same level of engine braking, which can feel less responsive during downhill driving․
- “Rubber Band” Effect⁚ Some drivers perceive a “rubber band” effect where the engine revs up without a corresponding increase in speed, especially during acceleration․
- Durability Concerns⁚ CVTs, while generally reliable, have historically faced concerns about their longevity, particularly in high-performance applications․
Infiniti CVT Maintenance and Longevity⁚
Proper maintenance is crucial for the longevity of any transmission, and CVTs are no exception․ Regular fluid changes, following the manufacturer’s recommended schedule, are essential․ Additionally, it’s important to avoid excessive towing or carrying heavy loads, as this can put undue stress on the transmission․
Conclusion⁚
Infiniti’s CVT transmissions represent a balance of fuel efficiency and smooth driving experience․ While they may not be as widely accepted as traditional automatic transmissions, they have continued to evolve and improve over the years․ If you’re considering an Infiniti vehicle with a CVT, be sure to thoroughly research its performance and durability to make an informed decision․
