<P> CVTs have been used in aircraft electrical power generating systems since the 1950s and in Sports Car Club of America (SCCA) Formula 500 race cars since the early 1970s . Farm equipment, namely harvester combines, used variable belt drives as early as the 1950s, as well . CVTs were banned from Formula 1 in 1994 because of concerns that the best - funded teams would dominate if they managed to create a viable F1 CVT . More recently, CVT systems have been developed for go - karts and have proven to increase performance and engine life expectancy . The Tomcar range of off - road vehicles also utilizes the CVT system . </P> <P> Some drill presses and milling machines contain a pulley - based CVT where the output shaft has a pair of manually adjustable conical pulley halves through which a wide drive belt from the motor loops . The pulley on the motor, however, is usually fixed in diameter, or may have a series of given - diameter steps to allow a selection of speed ranges . A handwheel on the drill press, marked with a scale corresponding to the desired machine speed, is mounted to a reduction gearing system for the operator to precisely control the width of the gap between the pulley halves . This gap width thus adjusts the gearing ratio between the motor's fixed pulley and the output shaft's variable pulley, changing speed of the chuck . A tensioner pulley is implemented in the belt transmission to take up or release the slack in the belt as the speed is altered . In most cases, the speed must be changed with the motor running . </P> <P> CVTs should be distinguished from power - sharing transmissions (PSTs), as used in newer hybrid cars, such as the Toyota Prius, Highlander and Camry, the Nissan Altima, and newer - model Ford Escape Hybrid SUVs . CVT technology uses only one input from a prime mover and delivers variable output speeds and torque, whereas PST technology uses two prime mover inputs and varies the ratio of their contributions to output speed and power . These transmissions are fundamentally different . </P> <P> Some vehicles that offer CVT are the Chrysler Pacifica hybrid, the Ford C - MAX hybrid, the Mitsubishi Lancer, the Dodge Caliber, the Toyota Corolla, the Scion iQ, the Honda Insight, Fit, CR - Z hybrid, CR - V, Capa, Honda Civic, Honda Accord, the Nissan Tiida / Versa (SL, SV, and Note S Plus or higher models), Cube, Juke, Sentra, Altima, Maxima, 2013 1.2 Note, Rogue, X-Trail, Murano, Pathfinder, Sunny and the non-Mexican Micra, the Jeep Patriot and Compass, the Suzuki SX4 S - Cross, and the Subaru Forester, Impreza, Legacy, and Outback, Suzuki Kizashi, Toyota Allion 2009 onwards, Toyota Premio 2009 onwards, Toyota Avalon, Toyota Mark X, etc . </P>

Is there a torque converter in a cvt transmission
