The Hennessey Venom GT is an American sports car manufactured by Texas-based Hennessey Performance Engineering. It was revealed on March 29, 2010.
On January 21, 2013, the Venom GT set an average 0–300 kilometres per hour (0–186 mph) acceleration time of 13.63 seconds. 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 14.53 seconds, making it the unofficial 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.
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. As the run was in a single direction on road unworthy slick tires and only 11 cars have been produced to date, and is not a series production car, but registered as a modified Lotus Exige, it does not qualify as the world’s fastest production car in the Guiness Book of Records.
