Are CVTs the fuel-efficient transmissions of the future? @GreenCarReports investigates:

The concept of CVT has been around for almost 100 years now. Tanks used to use it on their transmissions. The major issue is cost and reliability. CVT is efficient but it used to have issue with reliabilities in high torque applications. Nissan's Murano used to 2 gears for low speed start up and then CVT at higher speed to alleviate the problem. Now, as materials improve, it is being used everywhere. CVT is certainly less complex and lighter than a traditional 6-speed or 8-speed transmission. The cost to produce them also has came down a lot which helps to compete against the traditional transmission design.
