The Hennessey Venom GT is an American sports car manufactured by Texas-based Hennessey Performance Engineering.[2] It was revealed on March 29, 2010.

On January 21, 2013, the Venom GT set a Guinness Book of Records for the fastest production car from 0–300 kilometres per hour (0–186 mph) with an average acceleration time of 13.63 seconds.[3] In addition, the car set an unofficial record for 0–200 mph (0–322 km/h) acceleration at 14.51 seconds, beating the Koenigsegg Agera R's time of 17.68 seconds, making it the unofficial fastest accelerating car in the world.[4][5]

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.

On February 14, 2014, on the Kennedy Space Center’s 3.22-mile shuttle landing strip in Florida, the Hennessey team recorded a top speed of 270.49 mph (435.31 km/h) with Director of Miller Motorsport Park, Brian Smith, at the wheel.[6] As the run was in a single direction and only 16 cars have been sold to date (to qualify Hennessey must build 30), it did qualify as the world's fastest production car in the Guinness Book of Records but was ultimately defeated by the Veyron Supersport.

Specifications[edit] Edit

Chassis[edit] Edit

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. For road use, the car is registered as a Lotus Exige (modified) and is not in fact a series production car.[1]

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.

Drivetrain[edit] Edit

The Venom GT is powered by twin turbocharged 7.0L [427ci] GM LSX V8 engine with an iron block and aluminum heads featuring twin precision ball bearing turbochargers. 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.[1] Engine power output is adjustable by three settings: 800 bhp (597 kW; 811 PS), 1,000 bhp (746 kW; 1,014 PS) and 1,200 bhp (895 kW; 1,217 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.[1] 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.

Production Edit

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 US$600,000 while the 1,200 hp version starts at US$1,000,000. In Europe, the Hennessey Venom GT price goes up by just under US$25,000. As of August 6, 2014, 16 of the proposed 29 Venom GTs have been sold
