Traditionally, manufacturers of limited production supercars utilize technology and components that are available from more mainstream companies. Long-established builders such as Pagani, which uses Mercedes-Benz engines in its cars, have found levels of success that might not have been otherwise possible if they had to design and build each and every component of their creation. Enter Swedish engineer Christian von Koenigsegg and his eponymous brand, which from the outset have pushed not only the boundaries of the supercar world, but of automotive technology as we know it.

Started in 1994 when Cristian was just 22 years old, Koenigsegg Automotive AB was founded for the sole purpose of building a world class sports car. By 2002 the company’s first production model, the CC8S, was driven out of the company’s Angelholm, Sweden factory. While the CC8S and the subsequent CCX and CCXR models had engines based on Ford architecture, Koenigsegg knew that to reach his ultimate goal his cars would need to be largely bespoke; the 2011 Agera was the first Koenigsegg to utilize an engine of the automaker’s own creation. Agera, Agera S, R, RS, and One:1 variants were produced through 2018, and all were powered by Koenigsegg’s lightweight 5.0-liter V-8, which utilized twin turbochargers to produce 960 hp at launch and up to 1,360 in later models. So prodigious was the Agera’s performance, it set multiple production car speed records including 0–400–0 km/h in 33.29 seconds and the highest speed achieved on a public road at 284.55 mph.

By 2016 Koenigsegg was widely considered the most advanced boutique car manufacturer in the world, further solidified by its patented and experimental “Freevalve” technology that utilizes pneumatic and magnetic control over intake and exhaust valves on an internal combustion engine. This system, which gives engineers full control of valve movements, stands to revolutionize the automotive industry. In a natural progression, it was time for Koenigsegg to apply its creativity to more advanced systems, and the hybrid-powered Regera was born, with all 80 planned units selling out shortly after introduction.

While the technical description of the Regera’s pioneering propulsion system can fill volumes, this passage from their website ably sums up the general layout: “The Koenigsegg Regera combines a powerful twin-turbo V8 combustion engine with three electric motors and cutting-edge battery power via new powertrain technology called Koenigsegg Direct Drive. This revolutionary technology removes the traditional gearbox, making the car lighter and more efficient.”

This is a vast over-simplification of the true wizardry behind the Koenigsegg Direct Drive system, which has completely replaced the car’s transmission by placing an electric motor on the 1,100 hp engine’s crankshaft and driving the differential directly through a fluid coupler. Two additional electric motors outboard of the differential drive the wheels through half shafts. The F1-derived battery is a relatively small and very light unit rated at 4.5kw/h, and the system is the first production hybrid system to run at 800 volts. Total output for the Regera is 1,500 hp and the new model promptly broke the Agera RS’s 0–400–0 km/h hour record with a time of 22.87 seconds.

All of this prodigious performance belies the beauty of the Koenigsegg system, which is its lack of multiple gear ratios, instead offering just one speed. From rest to its top speed of 251 mph, the Regera never shifts, instead it seamlessly and relentlessly accelerates toward the horizon. At a more mundane pace the sensation is the same; all the power that you need at all times, regardless of speed.

For all of its achievements, maybe the Regera’s most impressive feature is what Koenigsegg calls “Autoskin.” Hydraulics operate all body closures completely automatically, adding further utility from the car’s built-in pumps and reservoirs from the suspension system. Proximity sensors in the panels keep them from running into solid objects and pressure sensors reverse the panel’s motion if resistance is detected.

The Regera offered here is a 2020 model consigned from its original owner and showing just 369 miles at the time of cataloguing. This tastefully specified example is finished in non-metallic Battle Grey over a Desiato Black interior that is extensively accented with bare carbon fiber. Benefiting from $710,200 worth of options added to its US-specification base price of $2,213,000, this Regera is importantly equipped with the desirable Ghost Package, which offers revised aerodynamics that add 20% more downforce, and costs $285,000 all by itself. The $250,000 Environmental Power Upgrade was selected, adding 200 hp when running E85 fuel. Optional exterior carbon fiber panels such as air intakes, roof panel and bonnet, Speedster Sides, and inner rockers come to $103,700. Rounding out the extreme specs of this incredible Regera are Koenigsegg’s own Tresex Aircore carbon fiber wheels, a $57,000 option that reduces unsprung weight and improves aerodynamics.

Each of the just 80 Koenigsegg Regeras being built is a customized creation. This wonderful example offers collectors the rare opportunity to not only buy a practically new Regera, but one specified with care, taste, and a no-holds-barred approach to the option sheet. Truly a work of art and among the most sophisticated automobiles ever built, this Swedish masterpiece represents an opportunity that should garner your closest attention.
