The one mile run is not top speed. I would estimate it would take 5 miles or so to top out a stock Corvette. Now a motorcycle, that's a bit different. I could run my bike up to nearly top speed in a stretch of less than two miles. Tough to find a straight stretch long enough, and without possibility of farmers pulling out, to run a car up to top speed. So when we talk about why nobody does it, it's not just about bravery. Very few people have a location that would provide an opportunity to even try.

Z51 car in manual trans has the same gearing
In the A6 top speed is limited by horsepower not gearing, whether with the 2.56 in the base or the 2.73 in the Z51
This will be no different than the C6 with both versions having the gearing to pull 200mph if the power is there
With a little more power and less aerodynamics doubt there will be a difference from the C6. GM's focus was low end power and gas mileage with the LT1 and data will reflect that lack of top end improvement as more and more comes out.

There have been a couple of tires mentioned for the c7. If either or both have speed ratings, there will be an electronic speed limiter. Before I would make a decision on z51 versus base model, I would want information about which tires are included. Just me of course.

The Z51 manual is geared differently than the non-Z51 manual.
The Z51 auto is geared differently than the non-Z51 auto.
And the manual gets to its top speed in 5th gear. That's where it will run out of gear. Not power. If the car had enough power, it could pull well into the mid 200's with 6th gear. And I'm positive it won't have enough power to pull into even the 120's in 7th.

What are you guys talking about? The car will run out of power LONG before running out of gear. The C5, C6 and I'm sure the C7 are GEARED for over 300mph. You just don't have enough power to get out of 5th.

The base C6 has a .71:1 5th gear. That means it will hit 191 MPH at 5850 RPM. If it had another 300 HP(760 total) it might hit 6500 RPM in 5th gear @ 212 MPH.
The Z51 has a .74:1 5th gear. That means it will hit 191 MPH at 6100 RPM. If it had another 200 HP(660 total) it might hit 6500 RPM in 5th gear @ 203 MPH.
In both cases the car does not have enough horsepower to get the engine over ~5850 RPM in 5th gear on the base C7, or get the engine over ~6100 RPM in 5th gear on the Z51.

Depending on the aero properties... everything else will virtually be a wash.

While the C7's "non-official" Cd of .28 is slightly lower than the base C6's .287, the C7 has a larger frontal area so there might not be an improvement in CdA for the C7 over the Base C6.

I thought the C7 had LESS frontal area? Certainly less drag than GS or Z cars with those fender flares.

Top speed might be very close to the LS3 speeds...which honestly, the Porsche Turbo has been 190-199mph top speed for how many years? I've never heard them complain.
Who ever gets to reach those speeds? Interesting though....seems like yesterday I thought 175 mph for the C5 seemed like such a gap from the 165 mph C4 LT1. Now some are disappointed the entry Corvette will "only" top out at a hair over 190. First world problems.
On a sidenote, I still can't help but recall that old Motor Trend top speed test from 1997 with the Dodge Viper that hit 192 mph, 20 mph faster than the C5 tested with it. To think the new Viper "only" does a claimed 206 for a top speed nearly 17 years later is weird. That seemed like so long ago and now these cars are just catching up/passing that kind of speed. The new Viper really hasn't had as much of a ruckus impact....probably because there are a whole lot more players in the super car game than back in 1996.
