The C6 Z06 has been shipped to Germany for some Nurburgring testing...
Remember, the C5 Z06 pulled of a 7m56s lap.
You need huge horse power (like a CGT) to eat up DottingerHohe, the long back straight... you are on full throttle for about a minute (if I remember correctly) so if you cannot run up to a huge top speed and hold it all the way from Galgenkopf to past Tiergarten, you can see a very fast lap become a mediocre lap quite easily - witness the results of the Exige and Elise that tear up the mountain seciton, but then give away 20 seconds as they run down the endless straight at 150mph max speed.
That being said, we know the C6 Z06 will at least match (hopefully beat) the C5 Z06 through the most challenging twisty bits, like holding good speed through the Hocheichen and Hatzenbach complexes and being able to carry a fast speed up and through Flugplatz.
This will set the C6 up for a good run down the hill to Schwedenkreuz.
Again - we are confident the C6 Z will hold it's own in a 1G+ attack on Aremburg and allow a good solid charge down Fuchsrohre.
For sure the challange of getting through Adenauer-Forst quickly and smoothly is easily done - knowing how well the C5 Z managed it - The run from Metgesfeld to Bergwerk will be the same at least - hopefully a good 2 seconds quicker (gaining at each turn and on each straight through the section).
The extra 100hp for sure will allow the C6 Z to pull some serious speed up the mountain from Kesselchen, carry a good head of steam up to and through Angst Kurve - and again the chassis will be up to quickly getting from the Karussell through Hohe-Acht and on to Wipperman in a good time.
The run from Eschbach, down Pflanzgarten I and II up to Schwalbenschwanz can be quickly done if you have a great chassis and immense power on tap - something we know the C6 Z posses.
Based on an assumption that the numbers published everywhere have some basis in fact - and looking at the extra horspower and better chassis - I estimate the C6 Z06 will be
1 full second ahead of the C5 by
Aremburg, and have shaved
another second by
Kallenhard.
Add to this the
2 seconds gained from
Metzgesfeld to Bergwerk - and another
3 seconds by the time they reach the
Karussell.
I will say another
3 seconds won from
Karussell to Kleiner Karussell - and another
4 seconds as the C6 Z reaches 190mph down
Dottinger-Hohe, which helps shave another
1 second off by the time they get back to
T13.
That's abotu
15 seconds quicker.
7m41s by my reconing.
However, I am assuing that the C6 Z is an incremental ratchet up in the handling department from the C5 Z - if the C6 Z is really a great leap in chassis tuning, then you could see it carrying significantly more speed through some of the more technically complex sections - resulting in far greater straightaway speeds - as it would be exiting turns at higher speeds, with 100hp more on tap.
But I don't see the C6 Z pulling off a Carrera GT style brute force lap - because we don't have the HP to run 200mph down Dottinger-Hohe - or the chassis to run 170mph down Fuchsrohre or Pflanzgarten).
Any how, I wrote way more than I intended when I decided
7m41s is going to be my estimate.
