The 2009 Cadillac CTS-V, which is powered by a supercharged 6.2L V8 with an estimated 550 hp, managed to complete the lap in 7:59:32. If you recall the Nissan GT-R made it around the track in 7:29. GM is still working on the ZR1 to make sure it beats the Nissan’s time.
The CTS-V was driven around the track with no performance modifications and is the same car that will be in showrooms later this year.
The official time of 7:59:32 appears to be the fastest time of any production sedan.
