The LS6 was the first mainstream LSX engine to cross into the 400hp territory. It was originally the engine for the C5 Corvette Z06 and was rated for 405hp.
In 2004 and 2005 General Motors took their top of the line V8 and slammed it into their smallest Cadillac and thus the CTS-V was born.
Today it is not uncommon to find a gently used CTS-V from 2004 or 2005 for less than $25k. Making it a great deal for people looking for a mix of luxury, sport, power and a relative deal. You won’t find a cheaper 400hp sedan on the market today.
In 2006 and 2007 the CTS-V ended up with LS2 from the new Corvette. It also puts out 400hp, however, it is thought that the LS2 platform is a more reliably built platform and will readily handle more mods for a higher increased output.
The 2nd generation CTS-V is making news as it gets the supercharged V8 from the Corvette ZR1 and a major hp upgrade to 556hp.
But for those sports car fans who need more power than a G35 or an Audi S4 and wanting to get a good deal the CTS-V is great option.
