Hennessey ZR700 Corvette ZR1 - Video

Hennessey has released their performance upgrade package for the Corvette ZR1, called the Hennessey ZR700. As the name implies the Hennessey ZR700 Corvette ZR1 is powered by the 6.2-liter V8 supercharged engine that has been tuned to output 755 hp at 6,600 rpm and 730 lb-ft Torque at 4,000 rpm. The tuner says the Hennessey ZR700 Corvette ZR1 is able to get from 0 to 60 mph in 2.9 seconds and to 150 mph in 13.1 seconds. The car runs a quarter mile in 10.7 seconds at 139 mph and has an estimated top speed of 210 mph.

The Hennessey ZR700 Corvette ZR1 upgrade package includes a new supercharger pulley, a K&N air filter, stainless steel headers, high flow catalytic converters with mid pipes, high flow cylinder heads, a camshaft upgrade and an intercooler system upgrade. The Hennessey ZR700 Corvette ZR1 also has a re-programmed ECU. The Hennessey ZR700 Corvette ZR1 price has not been announced yet.

Hennessey Challenger SRT600

Hennessey Performance is apparently excited that the Dodge Challenger is finally here. They now offer a myriad of performance upgrades for the Challenger SRT8 including naturally aspirated versions of Chrysler's 6.1L VEMI V8 that increase power up to 575 horsepower, as well as supercharged and turbo versions producing up to 725 hp. There's clearly a power upgrade for everyone, but the most impressive appears to be the Challenger HPE600 Turbo, also known as the SRT600, which Hennessey reports has ripped off a quarter mile time of 11.9 seconds at 121 mph. The company called the car's launch during the run "conservative", though it was wearing optional Nitto Drag Radial tires at the time.

Of course, any big bump in power should be accompanied by equal improvements to the suspension and brakes, and Hennessey will also fit your car with a KW adjustable coil-over suspension, larger anti-roll bars, new bushings and unique StopTech brakes. The cost of a complete Challenger HPE600 Turbo package (including Hennessey embroidered floor mats but not the cost of the donor car, of course) is $74,950, though one can opt for just the engine upgrades and be liberated of only $29,500. In total you could be spending well north of $100,000 on a 725-hp Challenger if you find Hennessey's approach appealing, but look at this way, you'd probably be the only one.

Hennessey Venom GT super car concept gets you hooked on

Exhibiting more venomous images of its upcoming Venom GT supercar, Hennessey is geared up to spread more poison in the auto world. This beast gets its might from a twin-turbo version of the Dodge Viper's 8.4L V10 engine rated at 1,000 horsepower and is expected to mate with either a six-speed manual or sequential gearbox.

This 1,225kg mid-engine chassis will provide the proper means of distributing the horsepower into speed at a power/weight ratio of just 1.225kg per hp. Hennessey claims will see the car reach 100km/h from rest in just 2.5 seconds and up to 300km/h in around 14 seconds.

The Venom GT will be a much more engaging sports car to drive by challenging the driver with 1000+ HP in a chassis that is nearly 1500 lbs lighter than the Veyron. You can expect to see concept version of the Venom GT in 2009 with a production version following shortly after.

Hennessey Venom GT Concept Car

1000 BHP + 2700 lb Mid-Engine Chassis = New Benchmark of Sports Car Performance
HOUSTON, TEXAS (November 20, 2007) - Hennessey Performance Engineering today announced that it is introducing the company's first concept car - The Venom GT.

Penned by British auto designer, Steve Everitt, the Venom GT would incorporate Hennessey's potent Venom 1000 Twin Turbo Viper V10 powerplant into a light weight mid-engine chassis weighing "under 2,700 lbs". Power would be run through a 6-speed transmission or optional sequential gearbox.

With a power to weight ratio of just 2.7 lbs per bhp Hennessey estimates that the Venom GT could attain 0 to 100 km/h times in less than 2.5 sec. and a 0-300 km/h time of around 14 seconds. Company founder, John Hennessey, is careful to point out that the Venom GT is not being built as a "Veyron Slayer". Hennessey point out, saying, "The Veyron is an ultra fast and ultra luxurious grand touring car which also happens to be quicker and faster than any other road car, except for our Venom 1000 Twin Turbo SRT which beat the Veyron earlier this year from 0-200 mph. The Venom GT will be a much more engaging sports car to drive by challenging the driver with 1000+ HP in a chassis that is nearly 1500 lbs lighter than the Veyron."

Hennessey said, "The company already has existing Venom 1000 Twin Turbo clients interested in ordering the lighter, mid-engined Venom GT. "Right now are taking a serious look at building 2 concept cars that could be shown to the public sometime in 2009. If there is enough demand we may consider doing a very limited production run of the Venom GT."

If the Venom GT goes into production, it would be built at the company's facility at Lonestar Motorsports Park which is located just west of Houston, Texas.
