The concept of turning SUVs into pavement-pounding, drag-racing, supercar-shredding monster rods never ceases to amaze me, and by that I mean my jaw is on the floor and I'm completely boggled. I love me some automobiles (and vehicular transportation in general), but there's something about a nigh-three ton box on wheels and oodles of GO that seems...weird.

However, if monster rods - or high performance in general - are your cup of Starbucks soy latte, then Hennessey has got you covered (as if you didn't know that already, what with their cray-cray 1,000+ horsepower Vipers from way back when). Below, for your viewing pleasure, is video of a 2011 Cadillac Escalade drag racing a 2011 R35 GT-R and beating it.

American tuning firm Hennessey has crafted some pretty insane vehicles over the years. One of its most recent tunes is based on the Cadillac CTS-V Sport Wagon, which leaves GM’s factory with a 556-horsepower 6.2-liter V8 lump, but once Hennessey’s engineers perform their magic under the hood, output is lifted to 650 horsepower.

To show off the tuned CTS-V Sport Wagon’s potential, the Texas-based company brought the Cadillac to the track and drag raced it first against a stock 480HP Porsche 911 Turbo [997] and then a standard 485HP 2011 Nissan GT-R. Watch what happened in the video after the jump.

Remember Hennessey’s barnstorming, 1,200 hp (895 kW) Venom GT? Well its back and the journalistic titans at Road & Track have driven it. And there’s a video, to boot. Weighing in at a lithe 2,685 lbs (1,218 kg), the phenomenal Venom GT builds on Hennessey’s experience with tuning the Viper, 5th generation Camaro and various Cadillacs, among many others. It’s a simple formula, really. Big power + light weight = big fun. Read more »

Hennessey Performance has released another performance upgrade for Chevy's new Camaro SS, called the HPE600, based on 2010-2011 LS3 or L99 powered versions. It encompasses, among other things, a TVS2300 Supercharger System, which raises output to 602 hp and 595 lb-ft (807 Nm) of torque.

The Texas-based tuner claims that the HPE600 is capable of completing the 0-60mph (96km/h) sprint in the mid 3-second range and run the quarter mile (~400 meters) in 11 seconds.

Some say you can't make a Lotus any better. Well, maybe they haven't head of Hennessey and its SEMA Show-bound Venom GT. The American firm's new toy is based on the Lotus Elise and, in its flagship version, comes equipped with an out-of-this-world 1,200 hp (895 kW) twin turbocharged V8 engine sourced from the Corvette. Power is sent to the rear wheels through a six-speed manual gearbox.
