Although we’ve been hearing about Koenigsegg’s “Mega-GT” car for some time now, we haven’t heard a lot about its test program. That changed today following the publication of a video showing the first Gemera test car firing up and going for a drive with company CEO and founder Christian von Koenigsegg.

“There’s a lot of work going on behind the scenes here,” says von Koenigsegg. “We have a lot of test equipment in the car, data logging, and what’s cool with a four-seater is that we can actually have three developers and a driver working on the car, fine-tuning it together.”

Even though that does help save time for a company used to two-seaters, there’s still a lot of development to go for the Gemera. The engine in the test car is, at the time of filming, only capable of revving up to about 4,500 rpm, well shy of its expected redline.

That engine is a 2.0-liter, twin-turbocharged, three-cylinder Freevalve engine that produces a stunning 600 hp (447kW/608 PS) and 442 lb-ft (600 Nm) of torque on its own. It’s paired to three electric motors, though, and they combine to give the car a grand total of 1,700 hp (1,268 kW/1,724 PS).

So far, it still sounds a little rough but von Koenigsegg says that the test car is specifically designed to iron out issues such as the exhaust note, engine response, and how all of the systems play together. Still, he says that even at this early stage, the Gemera is fantastic to drive.

“Of course the technology in this car is otherworldly,” he says. He adds that they come together “to create this four-wheel-drive, four-wheel torque-vectoring, power monster—but a friendly monster. I mean it’s so easy and fun to drive that it just gives this unique experience that I’ve never experienced before.”

Perhaps the best news of all is that Koenigsegg will be releasing more and more details about the car’s development process from here on out. The automaker plans to build three hundred Gemeras, though it’s not entirely clear when they will head into production.
