In 2009, the second-generation CTS-V sedan achieved a lap time of 7:59.32 at the Nürburgring Nordschleife, which was the fastest documented time for a production sedan on factory tires —until the Porsche Panamera Turbo clocked a time of 7:56 in July 2009 —thanks to a heavily-tuned "LS9" EATON-supercharged 6 litres V8 engine that was borrowed from Corvette.
