The 2015 Koenigsegg One:1



When supercar makers get crazy, hardcore hyper-beast are born. Insane numbers are usually accompanying these track monsters. Numbers usually do not seem quite realistic. No. They seem quite far from reality, reflecting eccentricity and almost unthinkable speeds and times.

The 2015 One:1 is an amazing example to talk about hardcore creation by hardcore companies. Koenigsegg is always working hard, we dare to say. This little European car maker hasn’t built even the required quantity of numbers to be considered properly an established car maker. Maybe they are seeing thing from another point of view. They are focusing on quality, instead of quantity.

Koenigsegg’s quality standards seem to be the most hardcore ones in the industry if we take a moment to see the beastly creations with the weird name on it. The out-of-this-world specs offered by the 2015 One:1 are almost too extreme to believe, starting with its weight. Oh my, its weight.

Let’s take a further look of this insane piece of engineering.

Powertrain and Specs


The 2015 One:1 packs a colossal twin-turbo intercooled DOHC 32-valve 5.0 L V8 powerplant with enough muscle to generate up to 1341 hp at 7500 RPM and a maximum torque of 1011 lb-ft at 6000 RPM. Along with its unbelievable engine, there is a 7-speed automated manual transmission. Keeping with the basics, the 2015 One:1 can go from standstill to 60 mph (100 km/h) in just 2.5 seconds and reach an insane top speed of 273 mph (439 km/h).

The properly considered hypercar needs E85 fuel to reach its maximum potential. You need to know that with regular fuel, the 2015 One:1 is only able to produce up to 1161 hp. What a boring thing. Let’s stick with E85 from Hell.

The massive carbon-ceramic brakes discs provide the stopping power. In this matter, the One:1 features 397 mm discs in the front axle and 380 mm in the rear one, with six- and four-piston calipers respectively.

But beyond all these really interesting facts and specs, the most valuable and relevant one is its weight. Before knowing it, you must notice the origin of the name. The 2015 One:1 answers to the one-to-one relation between the total power output and the weight of the hypercar. Allegedly, this is the first time that a production vehicle achieves this feat. Also, if you do power calculations from horsepower to watts, this monster truly produce one megawatt.

It’s important to have in mind that the Agera R platform was used at first as an effective and well-oriented base to start developing the One:1. We are going to find a lot of similarities in both design and specs.

Mad and Senseless Design


As expected from a hypercar with such specs, the design of the 2015 One:1 is equally insane and unique, pushing all the boundaries. With a weight of 3100 lb (1406 kg), this beast uses a lot of extremely lightweight materials. Aluminum, carbon fiber, and titanium are often found.

Due its considerable low weight for the speeds it reaches, Koenigsegg considered totally necessary to generate an equally insane amount of downforce on the track. Its highly efficient form enjoys from 1345 lb (610 kg) of downforce after hitting the 160 mph mark. Several grills and radiator are a fundamental part of the hypercar’s main design. The massive active rear wing also plays a key role in terms of downforce generation, which, by the way, is brutal.


The interior didn’t suffer a severe lack of toys and convenience items. The car maker decided to put more than the necessary elements with practicability and style always in mind. Carbon fiber is widely present as well.

The Bottom Line for the One:1

The 2015 One:1 is one exciting example of hardcore hypercar creation. Unfortunately, is quite hard to get one. The production was limited to seven units only. Besides, this ultimate track tool is aimed to really wealthy people. Curiously, most of the build units were sent straight to China.

The price tag was around US$2.850.000.
