Michelin claims than the advantage of the Cup2r over the Cup2 is about 0.5s/km, maybe a bit less at Nurburgring but still considerable.
With the same tires, the time would be dangerously close.
Now consider a 4/5km racetrack, not a great deal for the "light" and expensive CSL.

While 15s is an eternity even on the NordSchleife I agree that the difference ought to be a bit larger taken the Cup Rs and power to weight advantage of the CSL. Either the 7:15 is a bit of a sandbag lap or it will be interesting to see a same day dyno on a CSL and M4C. Maybe the to the ground difference is less than 40 hp.
