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.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More
