I'm sure that's just the slow throttle map, same as C6.

That is what Chuck CoW's "CoW Booster" tune and add-on devices like Sprint Booster addressed on the C6. Apparently some canned and custom tunes can do a little with it too.

Maybe it just feels different cause it's hinged at the bottom?

It depends on the setting. In weather it is supposed to be slower to help avoid traction problems. I drive all the time in Sport so have not tried that setting. Could try tomorrow were are supposed to get our first snow in 2 years! About 2 inches with ice and sleet. No way the Vette is going anywhere!!
Just to set the record straight it is apparently not a potentiometer, they are using devices like a Hall effect sensor. There are various types but basically a magnet is moved past a coil providing an electrical signal. That is what the transmission uses to define which gear you’re going into for the rev matching. Back to the gas pedal, there are no contacting or rubbing parts as there would be with a potentiometer. Therefore the only resistance should be a spring to bring the pedal back or a carpet causing binding . The amount it moves the air intake butterfly is controlled by the computer so for some settings it is purposely made slower.

Just called service dept where I bought the car (Macmulkin) and they said it is what it is hmm, nothing they can do and have not heard of any recall on this so might have to live with it, when the weather gets better I will look into it further but right now its locked in public storage.

In product training they call the pedal getting "longer or shorter" - the eco,weather and tour are longer settings for the pedal (less responsive), the sport and track are shorter travel settings (more responsive).

That is a very good description, it should get longer and shorter as far as how it responds, but not stiffer as this thread started. Since they are apparently using non-contact sensors, if it is to “stiff” there is something causing friction or a carpet, etc. in the way.

That's exactly what is happening and I don't like it. I can understand their logic behind this feature but I personally don't like when they do anything that changes the amount of the responses to my inputs that I am expecting.

For example: I drove all week on Eco. On Saturday went out in Sport and ended up leaving rubber because the pedal was shorter and I got more response than I was expecting. I'm sure I'll get used to it so no biggy.

Not to be picky but I hold a BSEE. I know the difference

Why must you be so resistant to the current situation? I would hope your capacity for humor would have realized that there's no place like ohm

Oh man, you made me laugh out loud at that line. (of course I manage firmware engineers so I laugh at weird things)

Then you would know there is no rheostat in the C7 Corvette!
Holding?

Maybe to keep the accelerator from flopping around like a fish out of water, GM installed an old fashioned torsion spring on the pedal's pivot rod.
