The CVT has become well known mainly because it generally provides great gas economic climate and has much less moving elements than a normal transmission.
Therefore the typical computerized is somewhat compromised because the engine has to pick from just a few gear ratios. The main reason That is a lot less than excellent is for the reason that engines are best optimised to run only in a narrow rev range.
