It's only been live for a week, but we've already had to update our list of the world's most powerful cars, after Hennessey Performance surprised itself with an extreme dyno reading.

The Venom F5 is the car Hennessey hopes will demolish not only the fastest production car record now held by Bugatti, but also the 0-400-0 record recently reclaimed by Koenigsegg. With a long enough piece of road, there's every chance this wild machine could be the first to break 500 km/h (310.7 mph), which is the next nice round number to aim at since the Chiron hit 300 mph (483 km/h) last month. That's if Koenigsegg's Jesko doesn't get there first.

To claim the record, the Venom will need power. Lots and lots of power, to fight through the massive force of wind resistance you get at speeds more than four times faster than highway limits. Up until this morning, Hennessey was saying the Venom F5 would make some 1,600 horsepower, a truly staggering total and enough to place it equal fifth on our list of the most powerful production cars available, alongside the Jesko and the Chiron Super Sport 300+.

But the engine hadn't been dyno tested until now. And while 1,600 horses was the target, even John Hennessey himself appeared surprised with the bench test readout of 1,817 hp and 1,193 lb-ft (1,617.5 Nm) of torque.

“We exceeded our target horsepower number. Actually, we blew our target number out of the water by delivering over 1,800 horsepower,” said Hennessey. “The F5 engine has a very broad power band with over 1,000 lb-ft of torque available from 2,000 to 8,000 rpm. Give it the full throttle and it’s the most furious engine that we have ever built. Thus, we gave our F5 engine a special name: 'Fury.'”

Fury indeed. Check out the rage in action on the dyno below, and imagine that sound happening when you put your foot down in a lightweight, sub-3,000-lb (sub-1,361-kg) hypercar.

Venom. Great name, handsome ride, and the heartbeat this motor puts out...that's some serious sh*t! What's your poison?

Hard to believe that a catalytic converter can hold it's guts in under those conditions. They certainly went all out on parts.

THAT ... is one BAD BOY! WHEW!

From the video: "1193 Torque" What serious car geek promo would publish a stat without units? 1800 HP from 6.6 liters (400 CI). One wonders how many miles between required engine rebuilds? At least the Bughatti gets its 1500 HP from 8.0 liters, a more sustainable loading.

How much does such a powerplant weigh, and what does it cost?! Slightly down-tuned it would probably be an excellent aircraft engine, just needing a gearbox to give it more useful RPMs!

Which in a world going to hell in a hand basket due to global warming is good for exactly what? Glorifying waste is crap.

That thing is literally a fire breathing monster!
