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.
