Wow. That track is a tire-eater and suspension-beater. Lots of rough little elevation changes; especially uphill rises into a blind curve which is great for spinning out. Terrific demonstration of the magnetic suspension's ability to track all that! It's also quite a work-out for the driver. Great video!
Getting into the top 10 puts the ZL1 in some very lofty company there; awesome accomplishment for a "muscle" car.
