The real story on PARTIAL throttle response
Link removed
Threads like that have a potential C7 owner a little worried.
One of the strongest attractions of a C7 for me is low rpm torque and the push in the back that comes with a big V8.
I've only driven one C7 back in November 2013. It was a Z51 M7 and I remember not being awed by the low rpm throttle response and torque. I expected the C7 to feel like a beast even at partial throttle like my old 89 5.0 mustang modified to about 375 ft/lbs of torque felt, but the C7 did NOT feel like that. Indeed I was surprised that my CS at part throttle didn't feel that much slower than the C7 at part throttle.
It seems there is no question that wide open throttle the C7 is a beast, everyone agrees on that. But I for one don't drive wide open throttle all the time and enjoy a V8 that offers great torque and response at low rpms and partial throttle. So if current C7 drivers could please share their perception of low rpm partial throttle response on the C7, it would be most appreciated
Cheers

Track mode...
Seems to me that the throttle response in Track mode is more than sufficient at low RPM's. Just my opinion driving my non z51 3LT. I love the fact that the C7 can be driven conservatively (little old lady) when desired, but then can be driven like a beast when desired. :-)

I bet an experienced tuner can find a way to boost the low rpm part throttle response quite significantly.

Hmmm... I've had to delay ordering my C7 twice now (1 Elbow surgery and one more pending)--pretty upset..... Now I'm not so sure I should be....
Disappointing Low RPM torque? Does the car hesitate off the line? So in First or Second, if I step on the accelerator....it pauses? No immediate kick in the @ss? Really?????? Manual and A8?
Surely the C7 has more low rpm torque than my C5.....

Remember, the mode selection dial impacts throttle progression. My MN7 has plenty of low RPM torque. I keep it in Sport mode.

No low end torque?

"No low end torque?"

What he said!
Actually, I'm thinking of nicknaming mine "Buzz Lightyear" because every time I get on it that LT1 sure seems like it wants to go "to infinity and beyond"

Even some professional car writers have noted the C7 is not so good in this area...

and no one doubts that the C7 produces high levels of low rpm torque, the question is whether that torque is accessible with partial throttle. It was with my 89 5.0 stang...the jury seems to be out on whether it is with the C7

just wondering, how can you say it's fine if you have nothing to compare it against....of course everybody's is "fine" but how exactly do you know?

My understanding is that the C7 has a smaller diameter torque converter in the A6 than was the case with the C6 which means a higher stall speed. So, it lets the rpm come up more than would be the case with a larger diameter torque converter before it begins to move the car.
A surprise to me is how much my A6 C7s low end response has improved with increased mileage. This is with conservative driving at 2000 miles.
I do realize that much of the discussion is related to the M7.
I had an 88 Mustang GT and it wasn’t in the same universe as the C7 in any area other than the ability to carry more people. Don

"if you put your foot into it", do you mean full throttle? No one doubts the C7 on that count, it's whether it offers good throttle response at partial throttle.

FWIW, I have not noticed anything out of the ordinary when giving it any sort (from a little push, to a punch, to a stab) of throttle.
I have an LS2, LS3, and an LS7 to compare it with. Seems fine. I'm not sure how you can draw any sort of conclusion from a few miles and a few drives. They aren't the same engines or cars, so why should they act exactly the same?
Seems to me that it is a matter of learning the engine/car combo and driving accordingly.

I have a C5 and a C7, the throttle doesn't open until you reach 3000 RPM in the C5. It works great at the drag strip when bracket racing the car. It keeps the car from spinning it's *** off. The best the C5 went was 12.86 on a fast day shallow staging. I'm hoping that I have as much success with the C7 as I have with the C5. Time will tell, for us down in south Florida, the next race will be the Citrus Nationals at PBIR. The C7 will make it debut there and make it's maiden voyage down the 1/4 mile. I bought the C7 to race just like the C5 and I'm hoping that the throttle works just the same.
