You know what’s the easiest sign of a car having a powerful engine, other than the fact that it can go really fast? Listen to this video of the 2015 Koenigsegg One:1 and check out what happens when it starts up. You’re immediately greeted by a loud cracking noise followed by a powerful roar of the megacar’s 5.0-liter, twin-turbocharged, V-8 engine. But pay close attention to the background and you’ll hear a car alarm go off. Well, according to YouTube user Matthias Kierse, the man who uploaded this video, the car alarm belonged to a Ferrari, and was set off simply because the One:1 sprung to life

Yep. The Koenigsegg One:1’s engine noise makes Ferraris squeamish that they sound their alarms.

That’s insane, maybe even incomprehensible to a lot of people. But such is the muscle-flexing might of the One:1, considered as the world’s first megacar on account of its one-megawatt output. If your jaws haven’t dropped to the floor yet, I invite you to turn the volume up, close your eyes, and just listen to the visceral sound of that menacing engine. It’s like a combination of a stampeding buffalo herd and cracking thunder all rolled into one.

Then again, you shouldn’t be surprised since the One:1’s twin-turbo V-8 is packing 1,340 horsepower (1 megawatt) and 1,011 pound-feet of torque under that carbon-fiber hood. These numbers allow the megacar to sprint from 0 to 60 mph in around 2.8 seconds to go with a top speed of somewhere around 273 mph.

Anytime you have a car with that much power to call upon, you’re going to get noises like this anytime it clears its throat. If there aren’t already enough reasons to love the One:1, then you can add this video to that list.
