Same car set this lap (7:01.03) the lap before the accident....
But for a track as long as Nurburgring is the lap where the tyre has most of its performance.
Even more for the Kumho Ecsta V720 ACR, that are not for sure like any other road use tyre.
Nurburgring track section length that they used is 20,600 m, a track like Road America, that is a long track, is 6,515 m long.
You make three laps in Road America track and You have another km to do to finish one lap at Nurburgring.
@redriderbob - buddy, you've got contacts within FCA - was there any conversation surrounding supporting this endeavour? If so - why didn't they help? If not - why didn't they know?
I fail to see any reason why FCA would not have benefited from supporting this. Send out a WB Hellcat with the Viper as a passing of the torch, have em' both rock it.
What i said was based on what this incredible team has been saying.
That as good as the Kumhos are, and they are very very good, that they simply could not stand up to the heat. They said that they were asking more than any street tire should ever be asked to deliver.
They said that if they had a full race tire (that could stand the heat) they could have gone lots faster. But that was not their goal. They were there to prove the outer limits of a bone stock Viper ACR Extreme. I think they went above and beyond. They got some help, and some hindrance, but I feel that they did more than was asked.
It happens also with race tyres at Nurburgring, for example this year WTCC cars suffered problems with tyres at Nurburgring race event (track is longer since includes Nordschleife + GP track for total 25,378 m).
They had problems with the Yokohama race tyres during free practice, than Yokohama imposed some different setting limits to teams (more conservative, less performance), but on the two races (3 laps each) some had tyre problems.
Same situation occurred in 2016.
Have to wonder if the Vipers down force stressed the tires.

Yikes!! It one thing to go ludicrous speed, it's another to maintain composure when your ride turns into an out of control pinball. Thank goodness things didn't end up worse. Great effort by the drivers and crew. They (obviously) left it all out on the course.
