• For years, Hennessey has been making an attempt to beat Bugatti and others to create the world’s quickest manufacturing automobile, and now it is claiming the Venom F5 will get it there.
  • Built round a U.Ok.-built carbon-fiber tub weighing solely 192 kilos and a mid-mounted turbo V-8 named “Fury,” the Venom F5 is claimed to have a zero-to-62-mph time of two.6 seconds and a high pace above 311 mph.
  • John Hennessey informed C/D that though the corporate will produce one or two extra vehicles after this, the F5 is supposed to stay the model’s high performer.

    This is the automobile that’s set to make the Koenigsegg One:1 appear gradual and the Bugatti Chiron positively leisurely. The manufacturing Hennessey Venom F5 is a U.S. hypercar that—if it delivers on its maker’s daring claims—would be the quickest manufacturing automobile on the earth.

    Hennessey has lengthy been generally known as a tuner—one with a fame for extravagant claims up to now—however the Venom F5 marks its efficient debut as a producer in its personal proper. (The ultra-limited Venom GT that preceded it used a Lotus tub.) It’s named after the best ranking on the Fujita scale of hurricane power, and simply 24 vehicles might be constructed, every priced at $2.1 million.

    The F5 might be constructed in a brand new facility in Sealy, Texas, however the first completed automobile was accomplished within the U.Ok., the place the carbon-fiber monocoque is manufactured by KS Composites. And that explains why our first sight of it was at a former Royal Air Force air base within the English Midlands.

    The headline figures are a way past spectacular. Based on Hennessey’s numbers, the F5’s mid-mounted 90-degree turbocharged 6.6-liter V-8—dubbed “Fury” by the corporate—is about to be essentially the most highly effective engine ever fitted to a manufacturing automobile. This is a pushrod unit, a configuration well-known to Hennessey’s tuning operations, chosen for its compact dimensions and decrease middle of gravity. The firm claims a peak of 1817 horsepower at 8000 rpm—the engine revs out at 8200 rpm—accompanied by a 1193-pound-foot torque peak at 5500 rpm.

    The engine makes use of a cast-iron block and aluminum cylinder heads plus titanium consumption valves and Inconel exhaust valves. Connecting rods and pistons are solid, and each crankshaft and camshaft are made out of billet metal. Two ball-bearing turbochargers have 76-mm-diameter compressor wheels and 3D-printed titanium housings, delivering as much as 23 psi of increase. Drive reaches the rear wheels by a seven-speed CIMA single-clutch automated transmission and limited-slip differential, with gearbox ratios chosen to assist the F5 obtain its focused acceleration and high pace numbers.

    And high pace claims are much more outlandish. Hennessey, utilizing solely km/h measurements, says that the F5 might be able to a 2.6-second zero-to-62-mph time, a 4.7-second zero-to-124-mph time, an 8.4-second zero-to-186-mph time, and 15.5 seconds from zero to 248 mph. Top pace is focused to be in extra of 311 mph. If delivered, that may make the F5 quicker even than the 304-mph Bugatti Chiron. The F5’s ultratall seventh gear means the engine gained’t run out of revs till 334 mph, in response to Hennessey’s claims.

    The monstrous engine might be working in opposition to a minimal of mass. The F5’s carbon tub is claimed to weigh simply 190 kilos in its bare state. Most of the bodywork is carbon fiber, aside from an aluminum roof, with entrance and rear aluminum subframes. Mechanical complication is minimal: the F5 has a control-arm suspension at every nook, coil springs and separate reservoir dampers that may be adjusted for bump and rebound. Hennessey claims a curb weight of 3053 kilos, making the F5 barely heavier than the Koenigsegg One:1, however with 35 % extra energy.

    The apparent modifications between the completed F5 and the unique design proposal, which was proven at SEMA in 2017 after which on the Geneva auto present the next yr, have been made to enhance aerodynamic efficiency. The manufacturing automobile has misplaced the idea’s raised rear wing and gained a considerably bigger rear diffuser. There aren’t any energetic aerodynamic parts—uncommon on this a part of the market—with the F5 claimed to have the ability to alter downforce ranges by various journey peak to regulate the angle of airflow relative to its physique. The idea’s focused 0.33 drag coefficient hasn’t been realized, however a Cd determine of 0.39 can nonetheless be thought-about slippery. A “observe pack” that features a separate rear wing and better downforce might be optionally available, though specifying it will drop the F5’s high pace.

    Looking At the F5 Up Close

    The customary of match and end of the automobile we noticed within the U.Ok. appeared impressively excessive. The F5’s engineering workforce could be very happy with the single-piece rear panel, which is claimed to be the most important piece of machined carbon fiber used on any highway automobile (every of the vent holes have been individually milled). The quad exhaust tailpipes have been handled with Cerakote to assist with warmth dissipation; the hind lights additionally incorporate small vents. Unlike most rivals, the Hennessey has positioned the automobile’s fundamental radiators on the entrance, with the aspect vents behind the doorways channeling air to gearbox and oil coolers.

    The F5’s cabin is accessed by butterfly-opening doorways and over a narrower sill than the hypercar norm. Space feels respectable for a automobile on this section, with cheap elbow room between driver and passenger and sufficient head clearance for taller drivers, though baggage house is proscribed to a small space behind the seats and a compartment built-in into the passenger footwell.

    Clearly designed round operate slightly than luxurious, the F5’s inside is trimmed in leather-based and carbon fiber. The central display screen is for an Alpine infotainment system, and Hennessey has gone to the difficulty and expense of making bespoke switchgear for the controls that are not built-in into the floor of the steering wheel. The wheel has a cut-off yoke design impressed by fighter jets, with knobs and buttons for wipers, lights, quantity and switch indicators. A rotary swap will transfer between the F5’s dynamic modes: Sport, Wet, Drag, Track, and F5 V.Max, with that final one bringing the total energy output. Lacking airbags, the F5 will not have full federal homologation. John Hennessey mentioned the automobile might be offered beneath the “present and show” exemption.

    The F5’s chassis growth is being led by John Heinricy, former director of GM’s efficiency division. Hennessey says that his mission has been to create a automobile that may be capable of ship greater than only a headline high pace. But the corporate can also be decided to show the F5’s efficiency by doing simply that, with John Hennessey confirming to Car and Driver that he thinks the automobile might be able to an independently verified two-way 500 km/h (311 mph). The plan is to strive for an preliminary document on NASA’s 3.2-mile-long Kennedy Space Center runway subsequent yr, after which doubtlessly to change to a closed public freeway if this proves insufficiently lengthy.

    Hennessey additionally informed C/D that between 12 and 14 of the 24 F5 slated to be constructed have already been offered, and that his firm is planning to observe it with different fashions, seemingly utilizing a model of the identical core structure. “The F5 is the primary, however in some unspecified time in the future over the subsequent a number of years you will doubtlessly see one other one or two automobiles,” he mentioned. “But we now have no want, plan, or intention of constructing a automobile with a higher degree of energy to weight or absolute efficiency than the F5.”
