How does the new Hennessey flagship ‘H1000’ Cadillac CT5-V Blackwing stack up against its factory (stock) comparison? We headed to the Pennzoil Proving Ground with our 1000 HP and 966 lb-ft of torque CT5-V Blackwing to let it go head-to-head with a customer’s stock V.

Buckle up and turn those speakers up as this 1000-horsepower monster DEMOLISHES the stock example. Both cars are optioned with the 6-speed manual transmission, stage 2 carbon fiber kit, and magnetic ride suspension.
