The Cadillac CTS-V has gained a pretty special reputation since it debuted for the 2004 model year. The CTS-V has become associated with a big supercharged V8 from a Corvette and obscene amounts of power, and that's certainly the case for later variants. But all the way back in 2004, it launched with a slightly more humble 5.7-liter V8, albeit with a much less humble 400 hp. In the early 2000s, General Motors and Cadillac engineers wanted to try their hand at revitalizing the Cadillac brand, which had gotten a bit stale. The result, after hundreds of laps of the Nürburgring Nordschleife, was the 2003 Cadillac CTS, or Cartera Touring Sedan.
