Most of us are familiar with the continuously variable transmission. Disregarding reality for a minute, I think one should understand that the crucial components of making something (anything) turn at variable speeds requires that of a POWER SOURCE.. (engine) and its counterpart of a MEANS TO MAINTAIN OPTIMUM EFFICIENCY (transmission). correct me, if thats not as accurate as modern reality. I dont want to make this a broad topic as it could be so im sticking with the realistic truth. CVTs are used on snow mobiles, and a few cars today such as Toyota, Nissan, and Honda. All of which I have driven and show no sign of inconvenience when compared to the performance of most all other economical cars. The modern car engine is pretty set and stone, and apart from the hybrid scene, they seem to be doing fine and are getting more efficient/economic by the year.. But the question here is why have we invested so much study/application in the automatic transmission whereas the CVT hasn't been much of even a suggestion. As a part time technician in the field, i understand maintenance is rarely an issue just due to the far reliability of them in general. (Biggest wear and tear component being the belt.) And in essence, the CVT is a perfect solution for maintaining a precise optimum engine speed depending on the load of the engine... its gotta be perfect when put in combination with todays electronics of of strictly variable fuel feed depending on the cars physical state etc... The biggest problem i see is just the fact that todays CVTs are not durable under a heavy load. They havent yet been engineered (at least in mass production) in high performance vehicles which is another story alone. Any feelings? clarification? opinions? Iv discussed this with some techs in the field, and it just sounds like there's not enough money being put into their development due to the success of todays automatic transmissions. which are in my opinion (the most complex part of a car in engineering BY FAR).
