If these concept sketches are any indication, Hennessey is working on a Venom GT that is a pile of speed rolled around in bits of sexy. (Though if you squint a little, it looks like a Lotus Elise on steroids, which also wouldn’t be a bad thing.)
The Viper tuner turned supercar builder is supposedly working on this beast, with a twin-turbo, mid-mounted Viper V10 giving an estimated 0-60 mph time of just 2.4 seconds, and an estimated 0-200 mph time of just 15.7 seconds, with a top speed of 260 mph. (It’s helped by it’s 2,700 lbs. curb weight and 2.7 lbs. per horsepower ratio.)
Will this ever see the light of day?
We can only hope.

This might look like an ordinary Jeep Grand Cherokee, but with a uniquely located turbo (underneath the transmission) courtesy of John Hennessey, it’s now a Super Cherokee. Though Hennessey was just featured on DYH’s Tuner Tuesday for his 1000hp Viper, it’s hard to not give him a repeat showing with vehicles like this. The $27,900 SRT600 package turns an already powerful 420hp V8 into a ridiculously powerful 620hp monster, complete with a two year warranty. Seeing as the Jeep already pulls a .9 on the skidpad, has four wheel drive, and comes with all of the luxury any SUV owner could desire, Hennessey kept things simple and focused on the engine. Upgrades include:
- Forged Pistons (9.5:1 compression ratio)
- Forged Steel Connecting Rods
- Ported & Polished Cylinder Heads
- Balanced & Blueprinted Assembly
- Single Turbocharger
- Stainless Steel Turbo Headers
- Single 44 mm Wastegate
- Stainless Steel Dual 3 in. Exhaust System with Polished 4 in. Stainless Steel Exhaust Tips
- Front Mounted Air-to-Air Intercooler
- 3.5 in. Polished Inlet Tube with Blow-Off Valve
-
Upgraded Fuel Pump & Fuel System
So what does all that give you? How about:
- 0 – 60 mph: 3.5 seconds
- 0 – 100 mph: 8.9 seconds
-
1/4 mile: 11.9 seconds @ 116 mph
Just to put that in perspective, your Hennessey powered grocery getter will now beat a Porsche Cayenne Turbo S in the quarter by more than a second. But the Cayenne is just another SUV, what about cars? Glad you asked. The SRT600 will also win in a quarter mile drag if you go against any of the BMW M cars, all of the Mercedes AMG cars except for the SL65, the Audi S6, the Corvette, the Porsche 911 S, and even the Lamborghini Gallardo. The only cars that manage to best the beast are the 911 Turbo and the Corvette Z06, though they only manage to do it by a half of a second (and their trunks are just about big enough for a pair of swim trunks).
Fast is good.

Hennessey is the self-proclaimed “Home of the World’s Quickest, Fastest & Most Powerful Vipers”, and after seeing their latest creation, I have no reason to doubt that claim. The 2007 Venom 1000 Twin Turbo SRT is a force to be reckoned with, featuring 1000 hp and 1100 lb-ft of torque from the 8.4 liter (522 cubic inch) stroker motor.


With 0-60 times of 2.9 seconds, 0-100 times of 5.8 seconds, and a top speed of 255 mph, the number of cars that will outperform this beast can be counted on a single finger. Power comes from twin Garrett ball bearing turbos and a host of other engine tweaks including a front mounted air-to-air intercooler. Aesthetic modifications include a VenomAero body kit comprised of a front airdam, rear diffuser and a spoiler.

Traction (or what’s left of it) is improved with a lowered suspension featuring adjustable coil over shocks, a Brembo upgraded brake system, a differential upgrade, and Hennessey Venom 7R forged aluminum wheels (19×10 in the front, 20×13 in the rear) sporting Michelin Pilot tires.

Inside, you’re treated to Connelly leather seats, 5-point racing harnesses, a DVD navigation system, and custom floor mats. They even throw in a 2 year, 24,000-mile warranty (though it probably doesn’t cover the damage you’ll do when you park it around a tree). Thankfully, to aid in your survival, each purchase comes with a 1-day private track session with famed instructor Brian Smith (who, being a Viper test pilot, might just have the best job in the world). If looks to kill for and performance to die for don’t get your heart pumping, just consider the fact that you’re getting better performance than a Bugatti Veyron for 1/7 the price. At just $225,000, you better hurry your little millionaire ass off though, as they’re only going to let 24 lucky buyers in on the chance to solidify their place in the automotive history books.
