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.

Would be better pumped up another 25% in a RWD '95-96 Fleetwood.
Wait, 100+ HP loss from the flywheel to the tires?
If there were dyno haze, I could live with this, but c'mon...
