Huge horsepower is what Hennessey is known for, whether it's a Ford Raptor or the company's own Venom GT. So it's no surprise the turbocharging Texans have come up with another 1,200-horsepower CTS-V, but this time it's a wagon. And it sounds great.

Using the VR1200 upgrade kit, this 2013 Cadillac CTS-V Wagon lays down 1,058 horsepower at the rear wheels and over 1,200 pound-feet of torque. The monster is hovering near or above 1,000 horsepower from way down in the rpm range, too.

On the way to those monstrous dyno figures, it creates an auditory melange of V-8 roar and turbo whoosh that instantly transforms the otherwise unassuming wagon from sleeper to killer.
