The Continuously Variable Transmission (CVT) - Propelling The Cars of Today - and Tomorrow
The Continuously Variable
Unlike conventional automatic (and manual) transmissions which have fixed gears and gear ratios, the Continuously Variable Transmission offers the equivalent of 'gear changes' - but in a dramatically “stepless” manner that encompasses an infinite number of effective gear ratios. The principal effect is flexibility; the engineering allows the drive shaft to maintain a constant angular velocity over a range of output velocities. The results are dramatic and, in today's economy, important. By allowing the engine to run at the most efficient revolutions per minute (rpm) over a wide range of speeds and conditions, the CVT can provide better fuel economy than conventional transmissions, and can maximize the overall performance of a vehicle by allowing the engine to run at the optimal rpm for peak power. The CVT is currently applied in the Jeep Compass and Patriot models.
Advantages: contributes to greater fuel economy than conventional transmissions and maximizes overall performance by allowing the engine to operate at peak rpm.
