That’s not all, as CVTs bring with them a traditional whining sound resulting from all that belt-on-pulley action, that's extra profound when it has to cope with hefty loads like throughout hard read here acceleration or superior speeds. Additionally, a CVT will often want to keep the motor operating in its peak output rpm by varying its equipment ratio accordingly, And that's why the engine sounds “tortured” as the auto receives in control, even when it isn’t – that’s just the way it really works.
