The Koenigsegg Agrea R is undoubtedly a fast car. Its 5.0-liter V-8 is force-fed by twin turbos that help it crank out 1,140 horsepower and 885 pound-feet of torque. But what happens when you swap out the stock turbos for something a little larger? How about 1,400 horsepower. Yep, that’s exactly what we’ve got here, and boy does it sound angry.

This Agera R and its Lamborghini Aventador wingman bomb some European country roads. The Koenigsegg makes itself well-know thanks to its ferociously loud exhaust, turbo spool, and screeching tires. Just listen to that sound. It’s pure madness wrapped in a car body.

In stock form, the Agera R rockets to 60 mph in a blistering 2.8 seconds and has a top speed of more than 273 mph. We can only guess the extra 260 horsepower would drop its 0-to-60-mph time a few tenths while expanding its top speed by a few miles per hour. Then again, the added grunt might make hooking up that much more difficult. There are several instances in the video of the $1.6 million hypercar slipping sideways at speed; the tires were just unable to hold the road.

Make sure you can turn the volume up for this video. The amount of turbo swooshing is addicting. It’s amplified even more by a few tunnels on the route, making the monstrous sound echo like Godzilla screaming while stomping New York City.

The Koenigsegg Agera R is a hand-built hypercar constructed by craftsman in a garage in Sweden. Customers are able to order their cars in just about any color and interior combination they desire. The twin-turbo, 5.0-liter V-8 features some impressive technology in order to make its power. The cylinder walls are coated with nanotechnology that greatly reduces friction, allowing a 7,500 redline.

Power is listed at 1,140 horses and 885 pound-feet of torque. The 2,932-pound curb weight means the Agera R has an outlandish power-to-weight ratio. That allows a crazy-fast 2.8-second blast to 60 mph and a top speed of 273 mph.
