Since the moment I first saw a CTS-V Sport Wagon parked outside of the Hennessey headquarters in Sealy, Texas I knew a quarter-mile run video was coming. But a Porsche 911 Turbo versus a 650 HP Hennessey-tuned Caddy station wagon? Ridiculous.
Say hello to the Hennessey V650, a Cadillac CTS-V Coupe fluffed up to produce a satisfying 650-hp at the flywheel. This dyno run shows the wheels deliver a very adequate 544 hp and and 562 lb-ft of torque.
