I've changed to Top 20,40 and 60 for the average comparison. I've used Top 40 for the order in the table.
Some of the cars lower down will have struggled to get 40 representative laps, but for the top ones I think it is a fair comparison (as much as it can be).

Interesting. The Ferraris have the pace. Other than when you make it a bronze competition and Ben comes to the fore!
The lone Corvette looks good, of course.
Porsche show they have some pace, despite the disappointing qualifying.
And the Astons look the weakest, following the form of the year.
Attached are the laps in order of faster to slowest for each car. I have chose the fastest in the table from each manufacturer. The Ferrari and the Porsche are pretty consistent until about the 30th lap. The Corvette slowly falls off. The Aston is consistently slower.
It's all complicated by the driver that did the laps, but I think it'll be a battle between 3 manufacturers. Corvette only has one bullet though.
