When you are making a turn in a curve, you slow down, set a gear, control throttle, and leave the corner with full throttle.

Both AT and MT would be in RPM range between around 4500~6500 and try to maintain best throttle opening just before tire slips.(AT would be in manual mode to be in a certain gear)

Is there response difference between MT and AT when controling throttle in a corner?

I guess AT would have a dull response due to power delivery by fluid but does anybody have experience between these two transmissions? If you have, how much?

 

The AT doesn't engine brake quite like an MT, but the efficiency in modern automatics makes the power delivery on exit is more a function of the gear ratio than the type of transmission.

 

What about difference between controling throttle during a turn? does AT give similar response to MT?(response time between changing throttle and the power delivery to the wheel)
Or did you mean engine brake for the response?

Thanks!

 

Power delivery during a turn is about the same response, although an expert with a M/T can control both the clutch and throttle to gain more precise control of engine RPMs and power output to the ground.

Using engine braking to slow the car while keeping RPMs high is less effective in an AT.

And yes, in this subject since I own both an AT and MT sedan, I can be speak for the amatuer racers fairly well. I don't consider myself an expert at heel-toe or hitting the apex perfectly, but for the spirited driving in do in my Gs, they're both good.

 

MT will always be easier to manipulate and control in cornering...

 

Due to the clutch maneuver?

 

yes, clutch/throttle - controlling rpms... for road course and any type of twisties MT is way easy to fully control what the car is doing (and will do)... and it easier to always know what gear you are in (for those that think that's not an issue for AT, take your car to a big track with lots of tight turns - you will find quickly that its not a given to know what gear you are in)...

 

Hmmmmmm

If clutch manuever helps to perform more sharp control, does it mean manual clutched transmission would have more sharp control over a transmission with automated clutch control(eg, SMG)which also does not have option for clutch manuever too?

I am not trying to put AT on the same line as SMG(they can not be) However, I am curious about what makes MT better at turning if power delivery responses to throttle control are same in mid to high RPM.

 

Easier for something who's well-practiced at such maneuvering, yes, but for an amatuer? I'd have to say no.

 

because you dont have the control over rpm in an AT that you do in an MT...

In a straight line it a different story... and the equal "power delivery" at given rpm doesn't favor either - but with AT you wont miss-shift and the rpm to shift is a fixed range in each gear (not fluctuating like on tight cornering)...

What are you trying to accomplish? Are you deciding on which trans to get for certain needs or what?...

 

haha probably later.

but for now, I am thinking about doing valve-body modification with adding paddle shifter for a road course.

But I wanted to know how far it would still be behind MT even if I do that.

 

there are so many other variables... I wouldnt be spending much time trying to determine how much faster MTs cornering based on shift is going to be... driver, brakes, tires, and suspension will all play as much or more of a roll...

paddle shifters are a good idea - and so is VB... so if you are trying to convince yourself to do it, I wouldnt hesitate...
