But in a sportily tuned CVT, the gearbox will choose a progressively lower gear ratio, as you hit the brakes as you approach a corner, but still keep the RPM more or less at 4000 RPM. And as you accelerate out of the corner, the gearbox will choose a progressively higher gear ratio - all this while keeping the revs close to 4000 RPM. |
While not exactly the same thing, VW DSG's do have the intelligence to adapt to the terrain. I have noticed that when I am driving in the ghats, even in D mode the DSG delays up shifts and downshifts faster to keep the engine at a higher RPM and more in the power band. So on a level stretch at 40-50 kmph, I more often than not will be in D5, at similar speeds if I am ascending or descending a ghat, the DSG more often than not will be in D3 or 4.
The converse also happens, on a straight long stretch if I am driving with a light foot in S mode, it up shifts sooner than it typically would do. Quote:

Actually there is some truth in this. Agree that the switch from an AT to MT is much harder for a person who has never driven an MT (In fact will be impossible for a lot of people). But even adapting to an AT from an MT for some people takes time. I guess this has something to do with the way a person has learnt driving and how the brain subconsciously manages it. Personally for me, when I drove an AT for the first time, as you said, it was a natural thing and I was fine and settled in 10 min. And I can switch to an MT (even after long gaps) without any issue. Same was true for one of my cousins who drives my car. But for another person (who has a lot of experience and is a good driver), the switch was hard. He would keep jamming the brake with the left leg, subconsciously try to shift gears. After 4-5 attempts which resulted in a few near misses, he did not want to drive my car any more. Then he tried again in some open roads by concentrating hard and overcoming the MT behavior.
Bottom line, it took some time for him to start driving a AT in a comfortable and relaxed manner and yes, I could not figure out why it was so difficult. |
