Hennessey Performance has decided to improve upon the already magical Cadillac CTS-V with their new V700 upgrade package. If you recall, we drove the regular Cadillac CTS-V at the Gumball Rally last spring and it was worldwide bonkers, so adding more juice can only be a good thing. Adding a cold air induction system, new engine management system, long tube headers, three-inch exhaust system with high-flow cats, an upgraded intercooler, more aggressive cam and more, Hennessy was able to tweak more than 150 more horsepower out of the LSA V8 — that’s 707 hps at 6300 rpm, with 701 lb-ft torque. The end result is a top speed of 211 mph with a 0-60 mph time of just 3.3 seconds. Simply insane. I wonder how long till Hennessy drops their kit on the new CTS-V Coupe?
