The Koenigsegg Regera is not only one of the most unusual hypercars out there, but also one of the most powerful.

The hybrid powertrain hiding underneath the beautiful carbon bodywork combines a twin-turbo 1,100hp 5.0-liter V8 with three electric motors that make an additional 700hp. Combined, the Regera offers 1,500hp that go to the rear axle alone, which is driven directly by the powertrain.

Koenigsegg calls it Direct Drive and claims that it reduces energy losses by up to 50 percent when compared to a traditional transmission. A liquid-cooled 9.27kWh battery pack provides juice to the electric motors.

As you would expect, performance is breathtaking: 0-62mph (100km/h) comes in 2.8 seconds, 0-124mph (200km/h) in 6.6 and the 0-249mph (400km/h) in under 20 seconds. Despite the heavy battery pack and the three electric motors, the Regera tips the scales at 1,628kg (3,589lbs).

Koenigsegg has already sold out all 80 Regeras planned for production, so if you were in the market for one, better start scouting among the used examples.

Mr. JWW had the chance of driving one of the earliest Regeras up the Goodwood hillclimb, showing us what it feels like to drive such a powerful beast with just one gear.
