A lot of you are familiar with the Pagani Zonda HH, but only a few are aware that the owner of that Zonda has also commissioned a bespoke Koenigsegg Agera HH edition. This extremely rare hyper car has recently been spotted on the road.

Those amazing looks aside, Koenigsegg Agera HH is also unique in the way it sounds. That turbocharged V8 has one of the angriest soundtracks we’ve ever heard. It’s cold and aloof, kind of like the Swedes who made it!

Koenigsegg Agera HH and the Zonda HH belong to IT billionaire David Heinemeier Hansson. He is evidently very fond of the color blue, mixed with bare carbon fiber accents. HE also likes his super cars topless, as both the Zonda and the Agera are convertibles.

The Agera ranks among the world’s fastest cars, boasting a 1,030 horsepower engine that gives it a top speed of over 400 km/h. It is a tricky car to handle though, owing to the fact that it is both very light and very rear-wheel-drive. But hey, the guy hasn’t become a billionaire by shying away from difficult challenges!
