Hennessey Venom GT

The updated Hennessey Venom GT Spyder now claims to be the world’s fastest production convertible after hitting a top speed of 427.4km/h (265.6mph). Hennessey’s claim on another world record was verified by Racelogic, which had officials on hand and a Vbox speed measurement device inside the 2016 Venom GT Spyder.

The Hennessey Venom GT has set a new world record to become the quickest street-legal production car ever to make the dash from 0-300km/h. With Guinness World Records officials and VBox timing specialists on hand, the Venom GT set an official time of 13.63 seconds for the stratospheric sprint – the average of two runs completed in opposite directions along the runway at Ellington Airport in Texas (the first 13.18sec with a 6.5km/h tailwind, the second 14.08sec with a 9.7km/h headwind).

This, folks, is automotive insanity - the 2011 Hennessey Venom GT. A car which weighs just 1220kg and produces around 1030bhp. The result is a blistering 0-100km/h run of just 2.9 seconds and on to a top speed of 418km/h. Those figures are a little down on Hennessey's previous estimates for the 1200bhp version, as this seems to be the middle specced option, but they're still eye-wateringly quick.
