Question

[SSRL]

I have an Auto RedLine. I feel like it takes a while to react to me punching the pedal. I never feel the torque on the car like other cars i have owned.


So I guess what im saying is that it seems like im not going fast even when im at like 100 MPH, why?

Going fast and feeling torque are not the same thing. If you "feel" the torque, the torque is providing acceleration. Acceleration is what you "feel" (the punch into the back of the seat). If you are cruising at a constant 100 mph, you won't "feel" any torque at all. Of course, there is still torque (the torque required to overcome the aero drag and rolling resistance at 100 mph), but it won't be producing any net acceleration.

When comparing to other cars, you need to look at the torque curve of the other cars. Some cars have wide torque bands, where torque is delivered across a wide part of the RPM range. Other cars have narrower torque bands, where torque is made across a narrower part of the RPM range. Sometimes the narrower torque bands deliver more torque and power across the narrow band than is delivered by a wide torque car. Hence, once in the power band, the narrow torque car may deliver more acceleration (you will feel it more) when in the powerband. You also have to factor in turbo lag (if applicable). A lot of the big turbos have more lag, but deliver more power once they get rev'd up. Again, once they begin to deliver their performance, you will feel more acceleration.

I don't want to oversimplify, but one way to look at it is a wide torque quick response turbo will provide a more even acceleration profile than a narrow torque supported by big turbo. The former will accelerate smoothly from start to finish whereas the latter will start slower and then hit you with a bigger punch. Depending on how much time is lost getting everything spooled up, the latter might be behind at the finish line even though it will have delivered more gs to the body (felt faster) than the winner.

The SKY has a wide torque band and a smaller, quick reaction turbo. This provides an even acceleration profile almost from the start, and sustains that acceleration across the band and through the gears.

Have you validated your 'feelings' with quantifiable data?
Have done a 0-60? 0-100?
The tightness/slop of suspension can play a part in feel. –J

I have not tracked my car yet.

Maybe im the only one who feels this way.

What you say is torque is actually the acceleration of the car. The reason you don't "feel" any torque at 100 mph is because you felt it at take off but once your body is up to 100mph in motion unless you have 500 HP and punch it your probably will not "feel" anything. If you do have a high HP engine you still will not "feel" the torque what you are feeling is the acceleration of the automobile. Also What Bogie said " If you are cruising at a constant 100 mph, you won't "feel" any torque at all. Of course, there is still torque (the torque required to overcome the aero drag and rolling resistance at 100 mph), but it won't be producing any net acceleration."
I really do not agree with. If you feel anything, which you will even at 100 mph if you have enough HP, is acceleration not torque.

You don't need to go to a track to check 0-60. Get a stopwatch, jump on it from a standing start, hit stop when you pass 60mph. Should take less than 6 seconds if you do it right. If you don't want to work the watch at the same, time get a friend to work it for you.
The SKY doesn’t have the lag of the R, therefore it doesn't feel as ‘strong”. The power is delivered more linearly, rather than spiky.
Yet, with him doing a wholeshot and I just hitting it, I took a 6 foot lead on him, off a stop light, then hung untill 70. We know the R does it less than 6 seconds. -J

You are correct. You literally "feel" acceleration. Torque at the wheels produces the acceleration. When I say "feel the Torque", you may interpret that as "feel the effect of Torque", which is acceleration.
