Does the 2021 Teana CVT Use a Steel Chain?
3 Answers
The new Teana's CVT transmission uses a chain. Below are specific details about the Teana: 1. The Teana is a mid-size sedan under the Nissan brand, with dimensions of 4901mm in length, 1850mm in width, and 1450mm in height, and a wheelbase of 2825mm. 2. This model is equipped with two types of engines: a 2.0L turbocharged engine and a 2.0L naturally aspirated engine. The 2.0L naturally aspirated engine delivers a maximum power of 115kW at 6000 rpm and a maximum torque of 197Nm at 4400 rpm. This engine features dual C-VTC continuous variable valve timing system and direct fuel injection technology, with an aluminum alloy cylinder head and block. It is paired with a CVT transmission. The 2.0L turbocharged engine produces a maximum power of 179kW at 5400 rpm and a maximum torque of 371Nm at 4400 rpm. This engine is equipped with variable compression ratio technology and continuous variable valve timing system, also featuring an aluminum alloy cylinder head and block. It is matched with a CVT transmission. The use of a CVT transmission enhances gear shift smoothness and fuel efficiency, while also offering relatively better reliability and durability. 3. The Teana's front suspension employs a MacPherson independent suspension, and the rear suspension uses a multi-link independent suspension. The multi-link suspension improves the vehicle's handling and ride comfort.
As an automotive technology enthusiast, I frequently study transmission designs. The 2021 Altima's CVT uses a steel belt instead of a chain, which is the standard configuration for Nissan's XTRONIC CVT. The steel belt structure is lighter and more suitable for family cars, providing smooth acceleration and reduced fuel consumption, particularly noticeable in urban driving. Compared to steel chains, belts offer better noise control and lower costs, though they may not match chains' durability in high-torque scenarios. Nissan has optimized this CVT by adding simulated gear shifts to enhance driving feel. User feedback indicates the 2021 model's CVT rarely exhibits the overheating issues of earlier versions, offering long service life with regular fluid changes and avoiding aggressive driving. CVT technology is evolving toward efficiency and energy savings, with the Altima's choice reflecting a balanced design for mass markets.
As an owner of the 2021 Teana, I can share my real experience. The CVT transmission in this car indeed uses a steel belt, not a chain, which I specifically checked in the manual when purchasing. The driving experience is incredibly smooth, with no jerks during acceleration, and fuel consumption stays around 7 liters per 100 kilometers. A friend once asked why Nissan opted for a steel belt—I learned it's simpler to maintain and cheaper to repair. In daily commuting, the CVT has proven reliable with no failures, though it's advisable to change the transmission fluid every 60,000 kilometers to prevent wear. The steel belt performs well even during cold starts in winter, unlike some cars that develop strange noises. Overall, this CVT design is quite practical, ideal for average family use. Remember to avoid aggressive throttle use to protect the transmission.
