Established in 1994, Koenigsegg is already 23 years old as of 2017. And for a 23-year-old company, it has developed into quite the successful business. It all started with variations of the CC in the early 2000s and continued with the Agera in 2010. In 2015, the Swedish firm launched the Regera, its first ever hybrid. Come 2017 and Koenigsegg is working on brand-new vehicles, one of which is most likely a four-door sedan.

Although not yet confirmed for production, the sedan is more than a rumor, having been discussed by the Swedish brand in many interviews. While it made it pretty clear that it won't build an SUV (for now), Koenigsegg did admit that a four-door sedan is in the making. Not only the company's first vehicle that isn't a supercar, but it could also be the first high-performance luxury sedan with close to (or even more than) 1,000 horsepower. There's no information as to when the four-door will hit the market, but it's unlikely that it will happen before the 2019 model year.

Exterior

Picturing a four-door sedan made by a supercar-only company might sound difficult at first, but things become rather east once you forget about the classic three-box design. Because let's face it, Koenigsegg won't create a standardized four-door with the usual three-box design, longer rear door, and a proper decklid. Instead, it will aim for a sporty, sleek layout with a coupe-style roof and a rather short rear section. More specifically, the Swedish design will draw heavily from the company's supercars, so expect nothing more than an aggressive vehicle with seating for four people.

Our rendering artist designed just that and used the Regera as a base. Why the Regera and not the Agera, you ask? That's very simple. While the Agera is a very attractive and still-fresh supercar, it's design won't make it past the already discontinued nameplate. The Regera is much newer and it's pretty obvious that it points toward the future as far as styling goes.

Our vision is of a sedan that's nearly identical to the Regera up front. Koenigsegg will want to keep it recognizable so I think this is a safe bet. The bumper and aggressive splitter could very well carry over unchanged, including the large vents and the pointy, yet well rounded nose. The headlamps should be similar too. However, I think some features will be revised in order to get a slightly less racy appearance. For starters, Koenigsegg might drop the sharp vents mounted ahead of each front wheel. The hood vents should also be moved in a different position, while the hood itself will have a new design.

The latter is due to the fact that unlike the Regera, the sedan will have its engine in the front. This could also lead to a slightly longer front end and maybe even redesigned upper fenders, but for the most part, Koenigsegg will manage to keep this area very similar to the Regera.

Onto the sides, I think that the sedan will retain the Regera's sporty beltline and bare carbon-fiber detailing between the wheel arches. However, the massive vent that's nearly as long as the side skirt will have to go. For two reasons. First, such a big outlet is no longer necessary with the engine mounted up front. Second, it wouldn't leave enough room for the rear door. Granted, Koenigsegg could work something out, but it would definitely get a bit too expensive.

The roof will be brand-new of course. And while the front door section will be similar, Koenigsegg will go with a higher roof and taller glass section for added headroom. This may be a super sedan, but it needs to be comfortable and offer a better seating position for long trips. Toward the rear, the four-door will remain nearly as sporty as the Regera. The rear-door windows will likely be smaller than usual, while a wide C-pillar will replace the standard quarter window we see on most sedan. The sloping roof will have an aggressive angle toward the decklid.

Speaking of that, don't look for a standard decklid and trunk section. Instead, this sedan will get a more sportback design with a short rear section. A big wing like the Regera's is out of question too, but Koenigsegg will likely incorporate a spoiler that comes out of the bodywork when braking and cornering. The rear fascia design is a mystery right now, mostly because I have strong doubts that it will be as aggressive as the Regera's. Slim taillights, a big diffuser, and large exhaust pipes are obviously on the table, but don't expect them to be as extreme as on the company's supercars.

All told, the Koenigsegg sedan will be one menacing four-door!

Interior

Note: Regera interior pictured here.

Much like the exterior, the interior of the sedan should also be based on the Regera. The latter is in essence an Agera with a redesigned center console and center stack, but there are plenty of new features to call it unique. I expect the four-door to have a similar dashboard with organic lines and maybe even oval A/C vents. The instrument cluster could also retain its oval shape, but the steering wheel in front of it should be different. A flat bottom is very likely, but so are redesigned spokes and controls.

While the center console will probably have a similar design with carbon fiber side panels, the center stack should get a new control layout and a revised infotainment screen. By the time the sedan comes out, Koenigsegg will most likely roll out a new version of its infotainment system. It remains to be seen in which supercar it will be launched, but the sedan will most definitely get an upgraded version compared to the Regera.

Much like any other Koenigsegg out there, the driver and front passenger seat will have heavy bolstering. However, forget about the race-inspired standard seats, as the Swedish firm will be looking to make the four-door a more comfortable proposition. Sports seats will be optional though.

But by far the most noticeable change in this vehicle will be the rear section. A Koenigsegg with rear seats, can you imagine that?! A first for the brand, the rear passenger area will include seating for the people. While most sedans usually offer seating for up to three people, this would be a stretch for Koenigsegg. The coupe-style roof will offer limited headroom, while three people wouldn't have the comfort that the Swedish firm is looking to deliver with this car. Both seats will have solid bolstering, just in case the driver decides to floor it. A rear infotainment system could also be offered, albeit only as an option. Both the front and rear sections will be swathed in the finest leather and Alcantara available, backed by polished metal and carbon-fiber inlays and surfaces.

And as usual, everything will be customizable, just like any Koenigsegg supercar built until now.

Drivetrain

Note: Regera hybrid drivetrain pictured here.

Koenigsegg has two drivetrain options for the sedan, one being the twin-turbo, 5.0-liter V-8 in the Agera and the other one being the hybrid combo in the Regera. An electric drivetrain is also likely, but there's no specific information as to where Koenigsegg's development of an all-electric system is right now.

All told, it's safe to assume that the four-door will get its juice from the same hybrid drivetrain found in the Regera. However, output will be significantly lower. Powered by a twin-turbo, 5.0-liter V-8 rated at 1,100 horsepower and 921 pound-fet of torque and a couple of electric motors that generate 700 horsepower and 664 pound-feet, the Regera hits the pavement with "more than" 1,500 horses and "more than" 1,475 pound-feet of twist. There are reports that the supercar might be good for 1,800, but this has yet to be confirmed as of 2017. Either way, that's obviously more oomph than needed in a sedan, which is why I think that Koenigsegg will detune both the V-8 and the electric motors.

Some 900 horsepower and 850 pound-feet of torque should be enough to make the sedan a solid performer, while at the same time keep it manageable on public roads and other circumstances that don't require spirited driving.

Naturally, the sedan would be significantly slower, so don't expect it to hit the 60 mph mark as quick as the Regera, which needs only 2.7 seconds. However, a sub-four-second sprint is likely, which is still impressive for sedan.

For the more hardcore enthusiasts, Koegnisegg will probably create a more powerful version of the sedan, with more than 1,000 horsepower. Output is likely to sit at around the 1,200-horsepower and 1,200-pound-feet mark for this model, which would slash the 0-to-60 sprint to less than 3.5 seconds.

Arguably the biggest change in this hybrid layout will be V-8 engine being fitted in front of the cabin, rather than behind the seats, like in the Regera. The rest of the hybrid configuration should remain somewhat similar, with one electric motor-generator on the crankshaft acting as starter and generator for torque fill and two wheel-shaft mounted electric motors driving each rear wheel and providing torque vectoring. The electric motors should be powered by a 4.5-kWh, 800-volt, liquid cooled battery pack developed by Rimac Automobili.

Prices

Pricing? Are you sure you want to talk about it? Because you know, if you have to ask about it, you probably can't afford it. We already know that Koenigsegg vehicles are far from affordable, with both the Agera and Regera retailing from at least $2 million before options. So it's safe to assume that extra seats, room, and a bigger trunk could translate into an even bigger sticker. Maybe around the $2.5 million mark? Well, that would be before options, so a specced-up sedan will probably fetch in excess of $3 million.

Competition

Competitors? I'll be honest here buddy, you're asking too much. The market is literaly flooded with four-door sedans right now, but none of them can deliver the performance and luxury features of a Koenigsegg. Some come close, but you'll need to wait a while longer for proper options.

Tesla Model S P100D

But hey, if you can settle with horsepower and speed and you don't need a gas engine and luxury features, you can always go with the Tesla Model S. The range-topping model, called the P100D, comes with more than 700 horsepower and an absolutely crazy Ludicrous+ mode that sends it flying from 0 to 60 mph in a scant 2.4 seconds. It might be an EV, but it's capable of winning a drag race against just about any production supercar out there. The Bugatti Chiron, the LaFerrari, the Porsche 918 Spyder, you name it, and this Model S will put it to shame at the finish line. And while it may not have the luxury features of a Koenigsegg, it can seat up to seven passengers and it doesn't require spending at the fuel pump. Oh yeah, and it's significantly more affordable at $128,200 before options.

Bugatti Galibier

The Galibier is nothing more than a concept now, but it could become a production model in the near future. And if it does, it will be the only luxury sedan suited to go against the Koenigsegg. Expected to share many design features with the Chiron supercar, the Galibier will sport an interior worthy of the Bugatti name with tons of unique features and basically endless customization options. Power will come from the massive W-16 engine offered in the Chiron, but don't expect it to be as powerful as the supercar. Instead of the ludicrous 1,479 horsepower and 1,180 pound-feet, this sedan will probably come in at around 1,000 horsepower and 800 pound-feet of twist, which should be enough for a 0-to-60 mph sprint of under four seconds. Top speed should also be spectacular at over 200 mph. As far as pricing goes, the Galibier might be more expensive than the Koenigsegg, with the sticker expected to surpass the $3 million mark before options.

Conclusion

Unlike the SUV, which is more a rumor than anything else, the sedan is actually part of Koenigsegg's future plans. So while you might have spent your most recent minutes reading a speculative piece, there's a big change that much of the information in this review will become reality in the near future. And no matter the design and drivetrain, the Koenigsegg sedan will most definitely revolutionize the performance four-door market, much like the Swedish automaker did with the supercar niche.
