The magic 300 km/h figure is chased very often by modern supercars and performance cars as a top speed peg, even though car makers do play the social responsibility card of limiting top speeds of most run-off the mill cars to 250 km/h. Then there is the rarefied breed of hypercars that seek to push the boundaries of physics. Hennessey Performance (HPE) is one such company that makes these physics defying hypercars. The American performance car maker has now announced that their limited run Venom GT hypercar has smashed the 0-300 km/h world record with a two-way average timing of 13.63 seconds. The Hennessey Venom GT is powered by a twin turbocharged 7.0 litre V8 engine that develops a staggering 1,261PS of power and 1564Nm of torque. The Venom GT weighs in at a mere 1,244 giving the rear-wheel drive hypercar a power-to-weight ratio of 1PS per kg. With the firepower intact, Hennessey roped in Guinness representative Philip Robertson to witness the testing as well as to personally inspect the Venom GT before making any acceleration attempts.
