Sudden loss of acceleration is possible repair and replacement costs are high.

More power out of a smaller engine, for a steadier, more responsive acceleration.There are also fewer moving parts than traditional automatic transmissions. It has grown in popularity with improvements such as stronger, more advanced belts, hydraulic systems, sensors, and microprocessors. While the idea didn’t catch on, the CVT transmission came back in the late 1980s and was adopted by various automakers through the 1990s. An early CVT was included on the first automobile, produced by Karl Benz, in 1886. Modern CVT’s offer adaptability, but the idea goes back to the 16 th century with a drawing by Leonardo da Vinci. According to the EPA, a CVT transmission can yield a nearly 6% improvement in fuel economy. Both are connected by a flexible belt, allowing the system to adjust to any gear ratio very quickly. Variable-width pulleys make this possible one pulley is connected to the engine and another links to the wheels. The difference between standard and CVT cars is that rather than stepping between low and high speeds, the transitions among a practically infinite number of gear ratios lets the engine run in an optimal power range. For example, higher gears can be used to improve efficiency, while lower gears can provide better acceleration. Nowadays, it’s not uncommon to come across eight-, nine-, or 10- speed transmissions, to better optimize engine operation under different conditions. It provides different gears to drive in the typical car had just three or four gears in the past. How Does a Continuously Variable Transmission Work?Īn automobile’s transmission system transfers power from the engine to the wheels. Continue reading to learn how the system works and what advantages and disadvantages it has to offer. A CVT works differently than a standard transmission, and there are several pros and cons to consider. It is a type of automatic transmission that can improve fuel economy.
