The race to 300 mph is formally on. Hennessey Efficiency Engineering plans to start testing an F5 Venom prototype in 2019, with high-speed validation testing by the top of that yr. “We consider our automobile is able to going effectively past 300 mph,” CEO John Hennessey stated.
What is going to allow the F5 Venom to attain such a lofty aim?
The F5 Venom will probably be slippery (for a supercar) with a drag coefficient of Zero.33. A 7.6-liter twin-turbo V-Eight will blast it towards the 300-mph barrier. The engine is claimed to be able to 1,600 horsepower and 1,300 pound-feet of torque, however Hennessey stated it may not even require that a lot energy to hit the mark.
“At present our CFD testing and our engineers inform us we want about 1,520 horsepower to interrupt 300,” Hennessey stated. The engine has been examined to greater than 2,000 horsepower, however there aren’t any plans to go that far any time quickly.
Hennessey confirmed to Motor Authority that buyer automobiles will probably be delivered with the identical ultimate energy output score because the document automobile, no matter that could be.
Venues for testing and the record-attempt are already on Hennessey’s thoughts. The Shuttle Touchdown Facility in Brevard County, Florida, the place NASA landed house shuttles, is three.2 miles lengthy, and it is the place Hennessey set its earlier pace document with the Venom GT in 2014. Nevertheless it took 2.2 to 2.three miles of acceleration to hit 270.49 mph, and the final mile or so was saved for braking. It will take an extended stretch of pavement to interrupt 300 mph.
Testing at NASA’s facility is not out of the query. Hennessey stated that is sufficient room to run within the excessive 270s or low 280s.
The more than likely state of affairs is shutting down a freeway in Nevada, which is what Koenigsegg did for its document run, or Texas.
Hitting the 300-mph mark would obliterate the prevailing document, however that is simply step one. “I’d prefer to run 500 kph. Which is 311 and alter,” he stated. It is 310.68 mph.
Working that quantity would possibly require some form of particular version of the F5 Venom or a model with a lower-drag aerodynamic bundle than the present automobile. “After we break 300 we’ll see how a lot quicker we will go,” Hennessey stated.
Solely 24 F5 Venoms are slotted for manufacturing, and half will probably be offered to U.S. patrons whereas the opposite half dwell their finest life overseas. Allocations for the U.S. are offered out with a ready record, however solely 5 worldwide orders have been positioned.
A convertible mannequin can be a chance, but it surely has not been given the inexperienced mild but.
Hennessey has his eye on different efficiency figures as effectively. “Finally, if Dodge could make a four,000-pound Demon go Zero-60 in 2.three seconds, I really feel fairly good that we’ll have a tire on the F5 sooner or later that will probably be working within the excessive 1-second vary, 1.Eight, 1.9 second vary when that point comes,” Hennessey stated.
The American boutique supercar agency SSC has stepped into the top-speed sport with its new 1,750-horsepower Tuatara. Jerod Shelby, CEO of SSC North America stated the Tuatara’s the one one with a “authentic shot” at cracking 300 mph.
Hennessey’s response? “The bulls–t stops when the inexperienced flag drops.”
