If you were to travel just one year into the past and take a trip to the Geneva Auto Show,->ke228 you would see an exciting debut of the Koenigsegg Agera RS. Move forward just ten months, and you would find that all 25 units of the Agera RS were already spoken for – making it the fastest selling model in the brand's history. As you step forward into the present, you’ll find another Agera->ke3628 making its debut at the Geneva Auto Show, but this time, it is called the Koenigsegg One of 1 and it is a very special model.->ke2041

The One of 1 is part of Koenigsegg’s Agera Final program that is designed to pay homage to the Agera RS and give owners an unprecedented input into the design and specification of the car. A total of three vehicles will be built under the Agera Final series. The thing about these three models is that each one, like the one seen here, will be completely unique. When it comes to the model displayed here, the customer wanted an Agera that was as close as possible to the One:1 performance-wise, while maintaining the roof window, luggage space, and stowable roof. Koenigsegg->ke43 delivered in as fashionable a way as it could, debuting the first unique model at the Geneva Auto Show.

Since the Agera Final series is a three-car celebration of the sold-out Agera Range, Koenigsegg has opened its book of options to each customer, allowing any and every option to be selected as standard equipment. In addition, each model will also feature a bespoke aerodynamic treatment that will also set them apart from anything else out there. Some of the options that are now available at no cost include the 1MW engine upgrade, Aircore hollow carbon fiber wheels, and a clear or partially clear carbon finish.

So with that said, let’s take a close look at the “One of 1” and see what the customer chose to do with this totally unique Agera. One thing is for sure: we’ll never see another like it.

Exterior

On the outside, the biggest change to note is the custom designed, roof-mounted air intake. On the One:1 this system was huge for performance and downforce, but came with a loss of the ability to store the roof in the front luggage area, so Koenigsegg created a custom intake that gives the best worlds – a roof mounted intake with front vents, and the ability to store the roof away in the front luggage area. Now that is what you call going out of the way for your customer.

Up front, the customer went with a custom front splitter that features a smaller fin on each side of the middle, vertical fin and three winglets on each corner of the front fascia. To the sides, there are the side skirts with the wing in front of the rear wheel arches and a custom badge. In the rear, there is a top mounted wing with a second blade, custom designed shield mesh, custom badging on the wing, 3D printed twin-exit titanium exhaust outlet with the “One of 1” name imprinted on it, and a custom venture with adjustable winglets. All of these components were designed specifically for this car using computational fluid dynamics to optimize downforce without hampering the luggage area up front.

The One of 1 looks to ride on Koenigsegg’s Aircore hollow carbon fiber wheels that were designed for the Agera S, and features a custom paint layout with part of the car painted in red and the other part having a clear carbon finish to display the weaving of the carbon fiber body.

Interior

Inside there really isn’t a whole lot of changes to look for. As you can see the same dashboard, seats, steering wheel and floor mats carry over from the standard Agera RS. The customer did decide to upgrade the center console insert, which is now made of polished aluminum. Polished aluminum also looks to make up the surrounding ring of each HVAC vent as well. All of the buttons on the center console have been replaced with black, backlit units, and the three knobs below the infotainment display are also polished aluminum. The sides of the console look to have also taken on some polished aluminum, giving the interior just enough shine to go with the black and orange color scheme.

The only other noticeable difference is the badging on the dash. Instead of the bad on the dash displaying “Agera RS,” it now displays “One of 1” with “of" written vertically between “One" and “1.” The “1” badge is also done up in orange to match the stitching of the seats, outline of the dash, and Koenigsegg storage pound on the passenger side.

Drivetrain

I must say I like the taste of the One of 1’s owner. In the drivetrain department, the owner decided to go with the 1MW engine upgrade, which brings the full power of Koenigsegg’s twin-turbo V-8. That means the One of 1 has 1,360 horsepower and 1,011 pound-feet of torque on tap – 200 horsepower more than the 1,160 horsepower unit that came in the standard Agera RS.

Koenigsegg didn’t divulge specific performance information for this unique Agera, but I have a feeling that a 60 mph sprint comes in less than 2.5 seconds, with top speed upward of 250 mph. Of course, that is just a guess, so until Koenigsegg of the One of 1’s owner comes forward with performance specs, that's all we have to go by. We do know the One:1 with its 1,341 horsepower can hit 248 mph in about 20 seconds, so we can probably expect something similar from this 1,360 horsepower One of 1.

Prices

Koenigsegg had nothing to say as far as to what one of the three “Agera Final” models will cost. We do know that all options are offered at no cost for these three special models, but that is all we have to go by for pricing. Of course, we never got wind of the official starting price of the Agera RS, so we can’t even look there for a definite price. If I had to guess, I would say these three final Agera’s are probably hitting the bank for at least $2 million. Of course, pricing really doesn’t matter at this point, as all three units to be built were already sold prior to the debut of the One of 1. So, if you’re hoping to get one, you better wish upon a star, because chances are the three owners don’t have plans to get rid of their special Ageras anytime soon.

Competition

2015 Pagani Huayra Project Vulcan

Project Vulcan is a one-off Huayra represents the first Huayra to feature unique options. It was built as a tribute to Irv David, who set out to become the first Pagani importer in the U.S. Unfortunately, David passed away before his dream could become a reality, but his son Brett eventually took to his father’s footsteps and opened up Pagani Miami, which is an official Pagani dealership here in the U.S. Eight years after his son established Pagani Miami, he took delivery of this special one-off Huayra.

All of the unique upgrades are visual, so the car has the same 6.0-liter, 700 horsepower V-12 as other Huayra models. The most obvious customization is the red color scheme inside and out, but the most interesting part about the car is the special nameplate inside that was created by Horacio Pagani. It reads “In memory of Irv David” and has a silhouette of a Huayra in the background. Pricing information for the one-off was never released, and it might not be as fast as the One of 1, but it is one of those rare cars that you’ll probably never get your hands on.

1995 Lotec C1000

Trying to come up with a competitor for such a unique car like the One of 1 is difficult. You could list any of the 1,000+ horsepower supercars out there, but the power isn’t what makes the One of 1 so special. What does make it special is that it is the only one like it in the world. That said, I looked to the past for a good competitor, and I found the one-off 1995 Lotec C1000. The C1000 came at a cost of more than $2 million and was designed by a UAE citizen to be the fastest individually owned car in the world.

The car was powered by a 5.5-liter, twin-turbo V-8 engine that produced 1,000 horsepower and could propel the C1000 to a top speed of 252 mph. The engine was mated to a five-speed racing transmission, featured a carbon fiber and aerospace material frame, and could complete the 60 mph sprint in 3.2 seconds. Surely, this isn’t the fastest, individually owned car in the world anymore, but it is still a one-off that fell in the same price bracket as the Agera Final units are expected to go for.

Conclusion

I enjoy one-off cars because of their uniqueness, but when it comes to the Agera Final series, and the One of 1 specifically, I’m in love. There is a lot more to it than the fact that the car is unique. Koenigsegg worked with the owner of the car to build it exactly as he wanted, which means there is more to the car. The One of 1 reflects the owner’s soul and taste in livery and design. And, when it comes to custom designed cars, it really doesn’t get better than that.

What's even better, the car was put together and customized by Koenigsegg and not some aftermarket tuner – that just adds to how special this car really is. Nothing against aftermarket tuners and modifiers, but when you can get a truly one-off model direct from a manufacturer it is just that much better. I personally can’t wait to see what the other two one-off Ageras look like once they are completed.
