On January 21, 2013, the Venom GT set a new Guinness World Record for an average 0–300 kilometres per hour (0–190 mph) acceleration time of 13.63 seconds, thus making it the quickest modified production car in the world.  In addition, the car set an unofficial record for 0–200 mph (0–320 km/h) acceleration at 14.51 seconds, beating the Koenigsegg Agera R's time of 14.53 seconds, making it the fastest accelerating car in the world.
On April 3, 2013, the Hennessy Venom GT crested 427.6 km/h (265.7 mph) over the course of 2 miles (3.2 km) during testing at United States Naval Air Station Lemoore in Lemoore, California. Hennessey used two VBOX 3i data logging systems to document the run and had VBOX officials on hand to certify the numbers.
The Venom GT uses a highly modified Lotus Exige chassis. The manufacturer, Hennessey Performance Engineering, claims the modified chassis utilizes components from the Lotus Exige, including but not limited to the roof, doors, side glass, windscreen, dashboard, cockpit, floorpan, HVAC system, wiper and head lamps. Hennessey Performance and the Venom GT are not associated with Lotus Cars. 
The Venom GT has a production curb weight of 2,743 pounds (1,244 kg) aided by its lightweight carbon fiber bodywork and carbon fiber wheels. The brakes use Brembo 6-piston calipers in the front and 4-piston calipers in the rear. The rotors are 15 inches (380 mm) carbon ceramic units provided by Surface Transforms.
The Venom GT is powered by twin turbocharged 7.0L [427ci] V8 aluminum engine featuring Ball Bearing Turbocharging system. The engine produces 1,244 bhp (928 kW; 1,261 PS) of power at 6,600 rpm and 1,155 lb·ft (1,566 N·m) of torque at 4,400 rpm. Engine power output is adjustable by three settings: 800 bhp (597 kW; 811 PS), 1,000 bhp (746 kW; 1,014 PS) and 1,244 bhp (928 kW; 1,261 PS). The engine revs to 7,200 rpm.
The mid-engine V8 is mated to the rear wheels with a Ricardo 6-speed manual transmission. Hennessey claims that the car can achieve a top speed of 278 miles per hour (447 km/h), although this has never been tested.
A programmable traction control system will manage power output. Computational fluid dynamics tested bodywork and downforce also help keep the Venom GT stable. Under varying conditions on both the road and racetrack, an active aero system with adjustable rear wing will deploy. An adjustable suspension system will allow ride height adjustments (by 2.4 inches) according to speed and driving conditions. Michelin PS2 tires will also help put power to the ground.
Hennessey manufactures the power plants at its facility in Sealy, Texas. The engines are then air freighted to the company's assembly facility near Silverstone, England where the Venom GT is built and tested. Venom GT buyers will be offered a 1-day driver orientation and instruction program by a Hennessey factory test driver at a track in the UK or USA prior to delivery.
Hennessey plans to establish a network of Venom GT dealers and distributors in the Middle East, Europe, Russia, Australia and Asia. Production is limited to just 10 vehicles per year. The 750 hp Hennessey Venom GT price starts at 600,000 USD while the 1,200 hp version starts at 1,000,000 USD. If you want the car in Europe, the Hennessey Venom GT price goes up by just under 25,000 USD. As of October 21, 2011[update], 4 Venom GTs have been manufactured.
Venom GT Spyder
The Venom GT Spyder is an open top version of the Venom GT. Having decided to order a Venom GT, Aerosmith lead singer Steven Tyler approached Hennessey in Autumn 2011 and asked if an open-top version could be created. This involved structural changes which added 30 pounds (14 kg) to the curb weight. Tyler's was the first of five cars scheduled delivered for the 2013 model year.
