CVT (D) vs Sport mode

alex_GTS · Sep 27, 2007, 10:50 PM

Hello everyone!

Am I the only one thinking (and feeling lol) that when driving in D the car accelerates faster than in "sport mode" (aka paddle shifters) ?

Especially when driving at around 30-40 or 50 mph , when you floor it in D it goes much faster than when you floor it and downshift with the paddle shifters...

What do u guys think?

cheers

so long as the car remains at a peak power RPM point then thats what you will get with a CVT theoritically.

No. I noticed the exact opposite.

If you have it in drive, and you accelerate vs. having it in the tiptronic, it will only accelerate faster if you leave it in 6th gear. If you downshift to third or second, you'll end up accelerating a lot faster by shifting yourself. At least, that's how it seems to me.

I noticed that in the lower speeds and RPM s, (Like 1st, 2nd, and 3rd) I accelerate a lot faster in sports mode. Then I shift it to D once i get ready to go into 4th gear and I accelerate faster.

0-60 is no doubt faster via manual shifting. Off the line though, It seems that the standard Drive mode is quicker for my car. It really depends on the CVT though, it reacts differently for each of us based off what it learned initially. When I test drove the CVT it was a dog but I wasn't after speed so I bought it anyway. But its really another animal now. Its just a hair away from breaking the tires loose on pavement but will unload the inside tire if turning and accelerating hard. Hopefully someone comes out with a flash for the CVT brain because mine gets to about 45mph in first gear in manual mode...would be a hellava lot quicker if it was something like 30-35mph first gear

Unlike in D mode where there is a float in terms of engagement between the engine and transmission 90% or less. When you are in Sport mode your gear (pulley ratio) is 100% fixed. Or in traditional Manual transmission terms, your car gear is engaged fully. accelleration will be 99% determined by throttle position. The transmission is still government by the CVT ECU which if it detects the wrong gear or a fault will override the driver.

When in CVT , you will notice when you take your feet of the gas there may not be much engine braking effect, the CVT transmission will govern the float /engagement.

most of this is at low speeds. anything within the realm of normal driving your very smart or very stupid CVT ECU is controlling inputs while you are in CVT mode.

Unless you do something outside the parameters of Sport Mode you should have full 100% engagement control of the gear you are in.

Does that make sense, lol god maybe i should try again lol oh well.

lol, i think i get it but im not sure if if i got the right thing. Like i think i understand what your saying, but i think you wanted me to understand something else, so my understanding is wrong.
