【简答题】
The CVT offers a similar driving experience to an automatic, but operates using a completely different mechanism. In fact, the CVT doesn’t have gears at all — instead, it uses a system of belts and pulleys to produce an infinite range of ratios. The car’s computer decides how to adjust the pulleys to create the optimal ratio for the particular driving situation. This creates the CVT’s primary advantage: fuel economy.
