CVTs utilize a pulley procedure with a steel belt/chain to provide an infinite array of gear ratios, even though regular automatics have a hard and fast set of gear ratios. This enables for smoother acceleration and improved gas performance in CVTs.
Listed below are the responses to all your CVT inquiries, such as what is a CVT, what can make CVTs different from conventional automated transmissions, and what are the pros and cons of CVTs?
