When car companies want to show what their cars can do, they ship them to Germany's famed Nurburgring. Rain kept parts of the road damp, but even with that, the Z/28 lapped the track in 7:37.40. That's 4 seconds faster than the ZL1 and faster than the published times for the Porsche 911 Carrera S and the Lamborghini Murcielago LP640. The Z/28 logged over 1,000 miles around The 'Ring and knocked down much faster unofficial laps in the dry, like over 5 seconds faster. Still, the official time is quite impressive and GM plans on returning to Germany to make the unofficial times official.
