At the 2019 Geneva Motor Show, Koenigsegg revealed its highly anticipated successor to its world record-shattering Agera RS, the Jesko. With up to 1,600 horsepower on E85 fuel, the Jesko is not only the most powerful Koenigsegg to date but also possibly the most powerful road car ever with an internal combustion engine. Named after Koenigsegg founder and CEO Christian von Koenigsegg's father, the Jesko was sold out within days of its unveiling. Each one costs at least $2.8 million.

In June came the Cherry Red Edition, limited to only 10 examples. And now, according to The Supercar Blog, Koenigsegg is working on something else, supposedly an ultra-limited edition hypercar that only a select few have seen. The presentation, says TSB's sources, took place at Pebble Beach earlier this month to a small group of VIPs. Only 11 examples are planned.

Question is, will this new hypercar be based on the Jesko or the Regera? That's unknown at this time, as is the powertrain. Chances are it's likely to utilize the twin-turbocharged V8 Koenigsegg is very fond of. Whether it'll be connected to a hybrid system is another question we don't have an answer for just yet.

The mystery Koenigsegg could also have been the previously reported 300 mph Jesko. The so-called Jesko 300 is slated to be even more powerful than the "base" Jesko with an outrageous top speed. In fact, it will supposedly be capable of hitting 314 mph. So, what did those VIPs see at Pebble Beach? The Jesko 300? An updated Regera?

Unfortunately, it may be a bit of time until we have our answer because the only major international auto show Koenigsegg attends annually is Geneva, which is still several months away.

Every year though, Koenigsegg has been bringing something new to display, whether it's an all-new model or an enhanced version of an existing one. But one thing is definitely for certain: Koenigsegg has no intention of letting another manufacturer steal its top speed record.
