![]() Vehicles with (CVT) Continuously Variable TransmissionĬompared to their peers in Europe and America, Japanese manufacturers seem to favor CVT systems more. As a result, the car accelerates more smoothly, its fuel efficiency increases, and the entire driving experience is enhanced. The CVT program’s shiftless feature offers unmatched versatility and consistent angular velocity regardless of output speed. Other varieties of mechanical gearboxes, which offer a set number of gearboxes and require complex shifts between them, are not like it. As a result, the car may smoothly shift between some effective gear ratio ranges while moving. However if you gently accelarate its quiet and with moderate acceleration its fine also, its really just harsh sounding if pushed.In essence, a CVT system is an automated transmission that does not require the clutch pedal of a manual transmission. The harder you accelerate the noiser the engine note, like hard revving a normal car in third gear and holding it there. The Prius maintains a more constant engine note while you accelarate. Unlike other conventional cars where the engine tone starts low and builds as you accelerate and is repeated throughout the gear range so its constantly changing. The harder you press the accelerate the noisier the engine becomes. The harshness which in my opinion is basically a noisy engine under harsh acceleration. Driving it properly is simple, place your foot on the accelerator. There is no gear changes as such so the power delivery is very even. Hence the confusion over what to call it.Īn very easy explanation can be found here but Ive seen numerous similar articles and demos on the netĪs to how to drive it properly or having harsh gear changes. So really it is a gearbox and CVT but is quite unique in design for the automative industry. Its may not be like other CVT's with belts etc but again its end result is very similar as the transmission basically is constantly variable. This is a gear set and Ive avoided the name gear box but it is basically a box with gears that evenly transmist the power from the electric motors and ICE, It has a sun gear with planetary gears and a ring gear around it. The Toyota Hybrid does use gears to transmit power. It depends on what you consider a gear box. ![]() I wonder,did this hack actually drive the vehicle or just copy somebody elses remarks and add a few negative ones of his or her own? :) It does illustrate however, just how "expert" some of these journalists can be when they make erroneous remarks like "rough gear changes in hybrid". The toyota hybrid CVT doesnt have steps like a "rubber band" CVT I am guessing that a hack at carbuyer was searching for something bad to say about Toyota CVT systems in order to sell his article. If so, I will have no problems buying a Hybrid with CVT. I hope it's identical to the one found found in the Prius. Unless of course by "rough" they mean "noisy". I am surprised to read this: If the Hybrid drivetrain is exactly the same as in the Prius/previous Auris. by the quality of the build.Īt .uk, they don't like the "rough gear changes in hybrid". i.e.pedal to the floor then of course it is going to be loud,driven properly, not so noisy,anyone wanting an auto can expect this.This is my first Toyota and i have to say i am very impressed.so far. I like the CVT trans,and it only becomes noisy when driven wrong.if you drive it like a diesel needs to be driven. *Technically (for the pedantic amongst you), on the Prius there is a clutch between the engine and the hybrid transmission, but it doesn't operate as a conventional clutch as the plates are permanently engaged.īTW Nicolai, I have a bet with myself that you are never going to buy another car, ever, everything has problems The Continuously Variable Transmission on a Toyota Hybrid is achieved by controlling the speed of the two electric motors and one petrol engine. Mechanically, the Toyota Hybrid is a very elegant and simple system. There are no rubber belts (pull), steel belts (push), pulleys, clutches*, etc, in the Toyota Hybrid systems because there is no mechanical CVT gearbox. With the Gen 3, I think that terminology was dropped, perhaps it was too subtle and confusing for most journalist and the public to grasp! In the Gen 2 model, Toyota used to use the terminology eCVT to signify that their solution was different from a conventional CVT gearbox. Repeat after me - there is no gearbox in a Toyota Hybrid.
