Continuously Variable Transmissions (CVTs) are a type of automatic transmission that provides a seamless transition through a continuous range of gear ratios. Unlike traditional automatic transmissions with fixed gears, a CVT uses pulleys and a belt or chain to adjust gear ratios without discrete steps. This allows the engine to operate at its most efficient RPM for a given speed, potentially improving fuel economy. Early iterations of the Toyota RAV4 utilized traditional automatic transmissions.
The implementation of CVTs in vehicles offers benefits such as enhanced fuel efficiency and a smoother driving experience due to the elimination of gear shifting jolts. Historically, the adoption of CVTs was initially limited, but advancements in technology and materials have led to their increased prevalence in modern vehicles, focusing on optimizing engine performance and reducing emissions. This shift reflects a broader industry trend towards prioritizing efficiency and a refined driving experience.
