The Koenigsegg Agera One:1 has 1,321 horsepower and a top speed of somewhere around 273 mph. It produces 1,345 pounds of downward force at 160 mph in order to stay on the ground.

The Agera One:1 is the new megacar from Swedish automobile manufacturer Koenigsegg, which made the beast to celebrate the company's 20th anniversary.

Converted into the metric system, the vehicle boasts a power to weight ratio of 1,340 metric horse power to its 1,340 kilograms – hence the name, One:1.

To help get such stratospheric numbers, the car has a 3D printed variable turbo housing that gives improved response and bottom end torque, as well as a 3D printed titanium exhaust end piece which saves 400 grams compared to an aluminum counterpart.

Now 400 grams is just under a pound, which not may sound like much, but absolutely everything counts when you're talking about a car that is capable of pulling two Gs in a turn (with street legal tires).

How else are you going to pull that kind of power out of a 5.0-liter V8 engine?

And in case you were thinking about getting one, despite the fact they don't come with cup holders, you're out of luck. They're only making six and they're all pre-sold.
