Hennessey Venom F5 continues testing, bumps claim 250+ mph in F5 mode


Development of the Venom F5 hypercar continues as the Hennessey team progresses towards its goal of reaching a top speed of 311 mph.

On Monday, Hennessey posted a video showing the team performing high-speed stability tests at a declared speed of over 250 mph, with veteran GM engineer John Heinricy behind the wheel. The hypercar was in F5 mode, which uncorks the engine’s full 1,817 hp in E85. A Hennessey spokesperson said Motor authority that the race was about testing at full power and that no official timing was carried out as it was not a test of the absolute speed of the vehicle.

Hennessey plans to see how fast the Venom F5 will go by 3.2 miles on NASA’s runway in Florida in the coming months.

The first of three high-speed testing phases for the Hennessey Venom F5 was completed prior to the hypercar’s public debut at the Amelia Island Concours d’Elegance last May.During that time, Hennessey announced that the Venom F5 hit 200 mph during aerodynamic tests.

That speed, achieved on a 2.2-mile track at a former US Air Force base in Arkansas, is about two-thirds that of the Venom. claimed a top speed of 311 mphBut that test wasn’t about breaking records, either. The team was focusing on medium speed refinement and deceleration behavior, Hennessey said at the time.

The Venom F5’s 6.6-liter twin-turbo V-8 was also restricted to 900 hp, only about half its target power of 1,817 hp. With the taps wide open, Hennessey claims the V-8 will also produce 1,193 lb-ft of torque and throttle to 8,500 rpm (though it’s restricted to 8,200 rpm outside of F5 special mode) while running E85. Power is handled by a CIMA 7-speed automated single-clutch manual transmission.

In addition to the unused Air Force base, the test program has included stops at Hennessey’s own Sealy, Texas site, and at the UK’s Silverstone Speedway, where the first of 24 Venom hypercars was built. F5. Additional test sessions will be held at Laguna Seca and the Circuit of the Americas (COTA), according to Hennessey. Nothing is known yet about the approach of the third test phase.

The names “Hennessey” and “Venom” may sound familiar, but the Venom F5 is a different car than 265 mph Venom GT, and is built by a new company called Hennessey Special Vehicles (HSV), which is separate from Hennessey Performance Engineering’s modification business.

As with the Venom GT, Hennessey is looking to break the production car’s land speed record, this time topping 300 mph. . An alternative could be during the planned test at NASA’s runway. Stay tuned.
