Definitely not true.
I'm not sure what they'll get it to do eventually, but the car misses gas guzzler and goes 200 mph because it's geared for that rather than the Ring. GM obviously says "Oh yeah, well let's go race at the Ring!" because that's what their car is setup for and that's where they hope they can eek out a victory. There's plenty of road courses in America, but they obviously aren't confident enough to just pick one of the easily accessible big boy tracks here. The cars have already both run at VIR, there must be a reason GM didn't say "Let's go run them at VIR!" which at 4.5 miles and massive elevation changes is more than enough to discern what they are capable of.
The same thing in general can be said for any other pair of similar cars, really. That is, car "A" may do better than car "B" on
this road track rather than on
that one simply because its design/engineering is better suited to it....and/or car "B" may 'best' car "A" on a drag strip because the differences in the suspensions/gearing between the two
favors car "B", etc. So, "what (a particular car is) capable of" compared to some other car really does boil down to what either was specifically designed to do. Your observation that the 'Stang "misses gas guzzler and goes 200 mph because
it's geared for that rather than the Ring" illustrates the point. Therefore, whether this car is 'superior' to that one all comes down to what
purpose the buyer has in mind for it.
Not long ago someone here on The 'Forum opined that he could best a FGT on a
bicycle if the track were "tight" enough. That probably illustrates the point I'm trying to make better than I can.
All bench racing aside, I'd really, REALLY like to see an IRS equipped 5.8 'Stang (especially sans any gearing compromises) tackle the Ring! Oh, good lord! Katie bar the door! :eek :willy :banana
