ZR1 Sedan: Hennessey releases 600-800 hp packages for 2009 Cadillac CTS-V

As far as we can tell, John Hennessey and his crew have somehow warped time and space to create the 36-hour workday. With all the products the Texas-based tuner is coming out with, there's no other explanation. So in addition to creating the 705-hp Corvette ZR700, 715-hp GTR700 and a duo of force-fed Camaros, Hennessey has decided to tackle the 2009 Cadillac CTS-V – and in the process created a four-door ZR1.

The team is releasing four complete packages for Caddy's M5-fighter, ranging from a 610 hp version all the way to a twin-turbocharged 800 hp variant. You can check out each package, including horsepower, torque, mods and performance times, along with corresponding videos, after the jump. And we've also got a gallery of the fire-breathing CTS-V below.
