Hennessey

The Nissan GT-R is no slouch even among cars costing twice its price or more. It's also a very large car in relation to much of its competition. But it's dwarfed by the HPE1000 Hennessey twin-turbo Cadillac Escalade paired up with it in this video. Even worse: it gets outrun by the 6,000-pound...

Texan tuning firm Hennessey Performance Engineering is certainly no stranger to over-the-top modified cars, having released a string of 1,000+ horsepower Dodge Vipers in the past and even its own custom supercar powered by a twin-turbocharged LS9 V-8. With such a pedigree, it’s safe to say...

With only 10 examples scheduled to be built each year, it’s safe to say that the 2011 Hennessey Venom GT is one supercar you’re unlikely to lay eyes upon in the near future, if at all. Thankfully, the guys at Hennessey have unleashed this stunning gallery of their latest effort, with...

When the 2011 Chevrolet Camaro Convertible launched earlier this year, it was perhaps inevitable that the tuner market would follow with its own take on the car. Well-known tuner Hennessey has done just that, with its HPE600 Camaro Convertible. Using an Eaton TVS2300 Roots-type supercharger...

Aching for the sounds of some vicious, hotter-than-stock American V-8 action today? Hennessey has your fix: the 2011 HPE600 Chevy Camaro Convertible, previewed in this video. As you might guess from the car's name, the HPE600 packs 600 horsepower--602 to be exact--of supercharged, dyno-tuned fury...

The ultra-performance Hennessey Venom GT, built on a modified Lotus Elise platform but wrapped in custom body work, lengthened, and with a mind-bending 1,200-horsepower twin-turbo V-8 engine amidships, will make its North American debut at the 2010 SEMA show. This video gives a taste of the 262-mph...

Former Top Gear Stig Ben Collins was recently in Colombia helping General Motors and Hennessey Performance celebrate the launch of the 2011 Chevrolet Camaro in that country. Since a Hennessey dealer is the official GM importer for Colombia, it only made sense to invite the former Stig to show off...

You want 755 horsepower in a Camaro Convertible? Well, Hennessey Performance has something for you--if you're one of the first 24 people to place an order. It's the Hennessey HPE700 Camaro SS upgrade package, and it's available on both the hardtop and convertible models. Featuring a supercharged...

The Chevrolet Camaro Convertible isn’t due to hit showrooms until March of next year but we already have details on a very special version of the open-top muscle car from the guys at Texas-based tuner Hennessey Performance, one with 755 horsepower. The car is the new 2011 HPE700 LS9 Chevrolet...

Thought Hennessey’s LS9-packing 700 horsepower HPE700 was as extreme as Camaro tuning got? Think again because the Texan tuner is at it again and now offering mega 1,000 horsepower upgrades for the Chevy pony car. Called the HPE1000, the heart of Hennessey's latest kit is a 7.0-liter LSX V-8...

American-designed and built supercars are on the comeback, it seems, with the Devon Motorworks GTX making its debut at the 2009 Pebble Beach Concours d'Elegance and now Hennessey Performance Engineering revealing its Venom GT supercar in its final form for the first time. Originally announced as...

The 2009 SEMA show is fast approaching, and the hot tuner concepts are crawling out of the woodwork.

The Hennessey-tuned 700-horsepower Cadillac CTS-V accelerates so hard it activates the OnStar emergency system.

Hennessey Performance Engineering is best known for its highly tuned exotics, but soon it will be building its own supercar.

More details are starting to emerge surrounding Hennessey’s upcoming supercar including this latest image of the car’s rear. We already now that its powertrain will be based on the 1,000hp (745kW) twin-turbo 8.5L V10 unit from Hennessey’s Dodge Viper Venom, but according to the...

Hennessey has taken the already menacing Dodge Viper and turned it into a 585-cubic inch (9.5-liter) monster, just in time for Halloween. You’d expect that this much displacement would deliver a mountain of torque, and thankfully the Venom 800R, as its known, doesn’t disappoint. Claimed...

The Hennessey Viper may soon own the title of the world’s fastest car in production with a claimed top speed of 255 mph. With a sticker price of $225,000, the Hennessey-tuned speed king is a relative bargain when compared with the million-dollar supercars it outperforms. That's only if any of...
