Hennessey breaks the world speed record for a convertible with the Venom GT Spyder: 427.4 km/h!

Bugatti may have introduced what it calls the most impressive vehicle ever built, the Chiron, but the new car still has to prove it is able to reach the 500 km/h that its speedometer shows. Or anything close to it. While the French automaker does not set the new world speed record, the Hennessey Venom GT will remain as the fastest production car after having hit 435.31 km/h in 2014, even without the Guinness Book recognition. But Hennessey wants to reinforce that supremacy and has established a new world record today, now with the convertible version of the Venom GT, called Venom GT Spyder. At the Naval Air Station Lemoore, it has reached a top speed of 427.4 km/h. Topless! You can see the record-breaking in the video below.

If you have watched the film with all due respect, you will see Hennessey not only has broken a world record, but also anticipated the next one. According to the company, we will soon get to see the Venom F5, the Venom GT successor, promised in 2014. The new car should be even faster than the Venom GT and wear a more distinctive body. The current one derives from a Lotus Exige body and chassis.

Getting back to the Venom GT Spyder, it is 4.66 m long, 1.96 m wide, 1.14 m tall and has a wheelbase of 2.80 m. It weighs 1,244 kg and was powered by a 7.0 twin turbo LS7 V8 that generates 928 kW at 6,600 rpm and 1,566 Nm at 4,400 rpm. In case the owner does not want to tame all this power all the time, he can select 3 other outputs: 597 kW, 746 kW or 895 kW.

The question is that the engine has been already upgraded, possibly to be used by the Venom F5. It now delivers 1,082 kW at 7,200 rpm and 1,745 Nm at 4,200 rpm. Amazing by any standards. It is worth to note the LS7 is also the basis for the new Mazzanti Evantra EV-R. Will it be as powerful as the Venom GT? We’ll have an answer for that very soon. It would be nice if Hennessey showed the Venom F5 before the new Italian supercar, scheduled for June.

We could not ignore the picture of the triumph, taken by the team Hennessey beside the world record breaker machine. The banner “come and take it” has an address on it. Let’s see if Bugatti receives the message. And if it decides to react properly. With no speed limiter, preferably.
