A few weeks ago, word started spreading that a special edition - a one-off, actually - Koenigsegg Agera->ke3628 was being built for a Chinese client with pockets that run as deep as the Mariana Trench.

Now, word has it that the car, christened as the Koenigsegg->ke43 One:1, is already on track for completion. As this recent batch of photos will tell you, the one-off hyper car appears to be closed to finish with plenty of design modifications from the already ultra fast Agera.

Judging from the photos, the Koenigsegg One:1 has a radical body design that features an accented checkerboard carbon fiber finish on pretty much the entire body, including the more aggressive lower front splitter, the roof, the hood, and the rear spoiler. Carbon fiber is also present on the wheels while the rear seems to have been treated to a completely redesigned rear end with matching diffuser and exhaust tips.

All in all, the One:1's look makes the standard Agera look bland and mundane by comparison, something that's also evident in the powertrain its expected to carry. We already mentioned earlier that the One:1 will feature a modified version of the Agera's 5.0-liter V8 engine with a rumored output of 1,400 horsepower.

That's some serious juice that only a few production cars in this world can even come close to sniffing.

Now that the Koenigsegg One:1 looks ready to roll and be delivered to this obscenely wealthy Chinese individual, you can add this extreme hyper car to that very short list.
