Rubber Band Effect Cvt

This new 106bhp 1 5 litre petrol motor comes mated to a continuously variable transmission cvt.

Rubber band effect cvt.

Regardless of the typical rubber band effect of cvts the refinement of the engine and smooth drive. In a traditional automatic or manual engine rpms rise proportional to car speed then you shift to the next higher gear rpms drop back down and the process repeats. In a typical automatic gearbox the revs are constantly fluctuating to match your changing speeds as you move through multiple gears. Rubber band effect rather an issue is more an inherent feature of cvt to have better mileage.

Because the engine and the cvt have to work in a synchronized manner and one may be working harder until the desired effect is achieved there is a higher rate of repeated movements of parts within the system. For the driver there is a. The car speed does not jackup at pace in conjunction with rpm leading to slight delay in power performance pep for those seeking surge of car power especially during highway or fast drive. A common complaint is that they give the vehicle a rubber band effect of constant acceleration or deceleration depending on how the driver is pushing on the gas pedal.

In the case of the rubber band effect a continuously variable transmission system will cause the engine to hold its revolutions at the highest possible peak until the desired speed is reached. Automakers have recently started to counter this feeling by programming into the cvt false shift points that mimic the shifting behavior of a traditional automatic. What is the rubber band effect. The rubber band effect is where the engine speed seems to be unrelated to the speed of the vehicle.
