According to an article in CAR magazine issue 490 June 2003:
"Sometimes you can be a little too pleased with yourself. GM engineers testing the 400bhp Cadillac CTS V-Spec prototype at the Nurburgring Nordschliefe were all smiles after they'd offered the car to a BMW test driver who promptly beat his fastest ever M5 lap time. Until someone realised they'd just given the opposition a sneak preview of the fastest Caddy in history, that is. Doh!"

In other Cadillac news, CTS-V to get upgrade to 500HP 6.0L next-gen Corvette LS6 for 2006.
