We went to Germany's Nürburgring to challenge ourselves on the most demanding track in the world. With us, in spirit, was every great car that we'd ever competed with. The BMW M5. And the Mercedes-Benz E63. For it was their amazing abilities that pushed us to refine, improve and, ultimately, develop the world's fastest production sedan. The CTS-V, from Cadillac. The New Standard Of The World.
