If someone is a serious drag racer, then it's a Z. But then, if you're a serious drag racer, the C7 isn't the best choice.
If someone is a serious track rat, and the lower times are important, then it's a Z.
For most everything else (I don't care about stoplight drags, or bragging rights - been there, done that, grew out of it), what's not to like about a car that turns faster than most in sprints and 1/4's? A couple of tenths to 60 is......meh........to me at these levels.
It's really sort of funny to me - manufacturers keep stepping up the hp, and then increasing the nannies to reduce it because most cars can't put the hp down. But you still have to like what's going on and the choices we have!

If I didn't drive on the track, I'd definitely want the big fat torque curve of the Z06. Since I track, I don't want the extra power or the baggage that comes with it (weight,engine overheating, extra hell on brakes and transmission, etc).
But if you're asking if 460hp is under-powered, as in, will I not enjoy this car, no. It's not a dog. With that said, I can't imagine why you wouldn't want the extra power on the street if you can afford it.

Wanted a fast handling Hot Rod 50yrs ago.Now add looks and touring.
Not many cars do it all...This one does

0-60 on a GS is 3.6 Seconds while the Z06 time is 2.95, if .65 second is worth $15K then have at the Z06. For the track, the GS is a more balanced car but even with the better balance the torque is hard to overcome. Most Corvette drivers can not really handle either one. A really good driver can take the GS and either stay with the Z06 or out run it on a road course.
For Drag racing, with the same driver, you can not outrun the torque. This is coming from someone that drove a 66 427 (built with real raw torque) for many years.
The bottom line all comes down to how big your ***** are and how hard you want to push the car.
If you want to make minor changes to the GS, like adding a cold air intake, put headers and x-pipe/mufflers, then you can pull a lot more power from the GS. My 13 GS with these changes was pulling 450 hp at the rear wheel. That is more than 500 hp at the crank. Cold air and exhaust were the only changes.
Hope this helps, but don't wish your life away. Get whats make you happy.

I love my GS Z07 and I’ve had a handful of Audi S cars & Mercedes AMGs. Initially I thought the engine was too big and revved to slow. Now I’m only below 2500 rpms in first gear (M7) and the car is a blast to drive. Midrange is very strong and sounds awesome with the Borla X-pipe.
Could be happier still with lower gearing but the taller gearing makes sense for me as I daily drive it.

Huh?
I now have 1060 miles on my ‘18 GS and I must say that overall the power is plenty what I don’t like is that the engine is a “lazy” responder especially in the lower (below3000) RPM range which is typical for an old design (pushrod).
Having owned, and still do, modern design Audi and BMW’s the response or laziness is very annoying!
However I still love the car😀

What??? The “pushrod” design has more torque down low than an OHC engine. Rev it up drop the clutch and enjoy the response and power.

I'm with VXPLT, the GS 460HP is a bit slow/sluggish 15-40 MPH compared to my BMW's or Audi, just doesn't JUMP, more of a gradual Locomotive as said, but makes up for it in many more ways (Road gripping, Sound, Looks). It's all the power I want at 59 Years in suburbia, no place to USE all the power here, and the others here are right, I can always add power for $ 900-2,500. if I wanted with aftermarket
stuff.
stuff.
Not my experience at all. Is yours an automatic or M7? I have an M7.

The additional cost of owning a Z06 over a GS is indeed insignificant. Given the actual cost of the two models are actually not that far apart for example. HUD and Mag ride is included with 1LT with the Z06. Therefore the fuel cost in terms of octane requirement may be significant for long distance travel. All in all having the extra power is not that much more expensive overall. Makes considering a Z06 over a GS very worth considering for a value for cost point of view. Many Thanks.
If you think $14K is really not that much???If you can use it and can afford it get the Z06. Or take the $14K and have the LT1 built by a shop like Vengeance. Gotta love an NA engine!!!

The GS seems to have a slight advantage over the Z06 in handling, obviously the Z06 has the power advantage. For my needs I can have fun with the power way more often then the minute difference in handling. Yes you can massively feel the difference in power, the sound of the Z is far better, for me I'd be unhappy going from the Z51 to a GS. When I had the Z51 it never scared me, the Z does.
which is awesome.

Pushrod vs OHC has nothing to do with the torque curve. The engine doesn't give a **** whether the camshaft is above of below the valves. OHV has a lower RPM limit due to valve float (and it's pretty high with solid lifters) but that's about it. There are high low-end torque DOHC engines (diesel!) and screaming pushrod engines. Meh.

I agree and need to take mine well out of town to air it out a bit, and even then there's too much traffic to get beyond about 2nd gear at WOT. I would have no use for more than 460 hp and the car's appeal wouldn't be diminished if it had a bit less, IMO. A friend and long-time car nut persistently hounded me about driving too conservatively, but when I took him for a ride and punched it he said, "It pulls really well. Now I know why you can't punch it around town."

I set the steering to "Always Sport" regardless on driving mode BUT no such option with throttle control! The response was not what I was used to in my 2014 for 3 1/2 years! The reason is shown in the tables from the Owner's Manuals below! With the 2014 I had the max throttle response in Sport. Now would have to have it set in Track. That is far to stiff for normal driving!
If anyone is interested this a PDF of my install: http://netwelding.com/Throttle_Control.pdf
Note for my 2014 Z51, none MRC I used Sport and it was the max throttle control rate. For 2017 GS would have to have it set for Track to get the fastest throttle response.
I use a setting of 4 or 5, which Vitesse says is a linear response not the slow response of the OEM setting at Touring! Feels like my 2014 Z51 set ta Sport.

Who cares about throttle vs gas pedal position? It should be pedal vs tq output so it feels linear.

Pretty Linear Torque Curve from ~2000 to 4000 rpm. Thank you variable Cam Timing!

JerryU, has your Vitesse ever thrown CELs or throttle sensor codes? I installed one in my '18 Z51 and it started throwing codes and limp modes until I removed it??? I thought it was the Range I also plugged in for my auto but it was the Vitesse. I'm pretty sure I did it correctly as the plugs only go in one way.

That is definitely a good option to consider. Although, nicely built 600 hp engines can cost quite a bit, but having a cool running NA is probably worth it.
