“Hennessey says the Venom F5 will attempt two way record at NASA Shuttle Landing Facility in Florida in the first half of 2021.”

Tornados are not the natural disasters that we we encounter frequently in our geography; however, America is recorded as the place where the most tornado is experienced in every year. Tornados which produces tremendous energy and speed, are not only natural disasters but also indicate great power.

Hennessey Performance Engineering, founded in 1991 by John Hennessey in Texas, has been among the world’ most important names in mechanical modifications of sports car since then. The cars that the brand uses its own logo have been heavily modified versions of models such as Dogde Viper, Lotus Exige and Chevrolet Camaro. Texans will celebrate the 30th anniversary of their founding with the new year, also they are presenting their own cars as entirely an original model: Hennessey Venom F5.  Venom F5 takes its name from F5 which is strongest level used for categorization of tornadoes. Its engine and performance is most significant characteristics.

In the Hennessey Venom 5 which is announced to be produced only 24 units, half of the production will be kept in the USA, while remaining 12 cars will be produced for he rest of the world and right-hand drive verisons will also be offered. The mass production version of car, whose US price was announced as 2.1 $ million, was made significant changes compared to the first concept introduced in 2014. The second concept that appear at the 2017 SEMA Modified Fair seemed similar to the mass production. Aerodynamic efficiency is featured in every part of the body of Venom F5 which is a car developed to achieve fantastic speeds, and to ensure this, every part from the mirrors to bumpers, from the doors to the ceiling is shaped according to wind resistance. The first noticable part of the two person living area of the Venom F5, which is claimed to offer a suprisingly comfortable landing and boarding opportunity for such a car, is undoubtedly the ‘U’ shape steering wheel. It is claimed that Venom 5 will offer a suprisingly comfortable landing and boarding opportunity for such a car thanks to wing gate which contain rocker panels. Also, the first thing that draws attention in the two person living space of the Venom F5 is undoubtedly the “U” shaped steering wheel. Many functions are accessing through direction instrument which looks like taken from a Formula 1 car. There is a digital dashboard and Alpine multimedia system in the cockpit which is dominated by bare carbon fiber surfaces  and leather.

The 6.6 liter twin-turbo V8 engine located in the middle of the car, just in front of the rear axle, produce 1.817 HP (1842 PS), while the turque it transmits to the rear wheels is 1.617 Nm. on the 86 Kg carbon fiber chassis is also made of carbon fiber. Speaking of weight, the engine Hennessey calls “Fury” (anger, wrath) is 280 kg. When all the “kilos” come together , “dry weight” of the 4.666 mm long Venom 5 becomes 1.360 kg. Power/weight ratio of 1.298 HP / ton or in other words 1.34 HP kg.  The engine, which has an efficiency of 277 HP/ IT per liter, transfers its power with a 7 – stage sequential gearbox.

“Hennessey claims that when the “Furry” engine, a cross-plane crank V8, uses the fury to its fullest, the Venom F5 will surpass 500 km/ h and become the fastest car in the world.”

When we look at the performance values, which is the purpose of the Venom 5, after so many numerical values, we understand better why its name is F5. Hennessey, making 2.6 seconds for 0-100 km/h, needs 4.7 seconds for 0-200 km/h. The 0-400 km/h duration of Venom F5, which reaches from 0 to 300 km/h in 8.4 seconds, which can be called as 0-100 km/h accelaration of cars to be considered sportive, 15.5 seconds. Hennessey claims that when the “Fury” engine, a cross-plane crank V8, uses the fury to its fullets, Venom F5 will surpass 500 km /h and become the fastest car in the world. We use the word “claim” specifically because we have an example of SSC Tuatara in front us. As you know, although SSC, an American manufacturer, recently announced that it broket he average speed record by reaching 508.73 km/h with the Tuatara model, there were speculations that the record was not true and the brand announced that it will repeat the record attempt in coming months. Hennessey says Venom F5 will attempt a two-way record at NASA Shuttle Landing Facility in Florida, in the first half of 2021. Although the car’s maximum speed is not precisely disclosed, Hennessey technical chart states that the theoretical maximum speed in 7th gear is 534 km/h.
