Inside Koenigsegg – Preparing the Koenigsegg One:1

Did you watch the first Inside Koenigsegg video series last year? If not, click that link and get yourself educated about what it takes to build the most amazing cars in the world.

The latest iteration – the world’s first ‘megacar’ – is the Koenigsegg One:1, which as you’ll learn in the video is pronounced “one to one”. The premise is one horsepower for every kilogram of weight, making 1360hp (or one megawatt) in total. It’s an outstanding achievement and as you’ll see, they plan on going even further with the production version of the car.

This is the first video of /DRIVE’s second Inside Koenigsegg series. Christian von Koenigsegg presents a quick tour of the car as they’re preparing for it’s debut at the Geneva Motor Show.

  1. One main theme running through Christian’s mind is reducing the weight of the car. The solution,could be just 20 minutes down the freeway from my house, in Oak Creek, Wisconsin. There is the home of Chimera Batteries which are used in Lotus cars because they weigh only a couple of kilos.

    Over a year ago I spent a day at their small, fastidious production facility with a friend of mine from Toronto who drove down especially to have one installed in his 9-3 Turbo-X. We spent the day watching this little gem being custom made with Lithium cells being encased in the carbon-fiber case. then inserted into the engine compartment of the Saab. The reason for the time was this was the first Saab to have this battery so the time was spent adapting it to be secure due to its compact size. So this became the template for future Saabs. This saved about 20 kilos an left a lot of space because of its compact size. I hope Swade will past this on to Christian as this is for real and has past the brutal winter test that is still continuing as I write from North America.

    1. Actually, Koenigsegg have already looked at batteries. The battery in the Agera (and the One:1, I’d say) is not only lightweight, but also controlled by some very intelligent software.

      From their website:

      Intelligent Lifepo4 Battery – ILB
      The Agera is the first combustion engine powered production car in the world, with an intelligent Lithium Iron battery as standard equipment. First of all, this battery type saves significant weight and is more compact compared to traditional led acid batteries. Secondly lithium iron cells cannot reach thermal runway, unlike Li-ion batteries, which makes them very safe for automotive use.

      Furthermore, the ILB carries many intelligent functions, developed by Koenigsegg together with the battery supplier. Hypercars tend to be parked long periods of time and therefore their batteries can be drained if the car is not hooked up to a trickle charger. Even though all Koenigsegg cars come as standard with a trickle charger it is not always easy to remember, or even possible depending on location, to use it. It is also possible that a driver sometime forgets to turn off all consumers, like parking lights etc causing early battery drainage.

      Koenigsegg has therefore implemented a minimum current protection mode, to make the above issues something of the past. The new ILB therefore has an intelligent circuit built into it, so if the car is left on or standing for a long time, the battery shuts down when the voltage drops below a certain threshold. The shut down does not occur sooner than a traditional battery would have been left depleted and useless, so it does not take away any expected battery capacity. Then, if any essential buttons or a door knob is touched, the battery kicks back into life for 5 minutes and has enough power to operate all the functionalities in the car and start the engine and thereby giving charge back to the battery.

      Given this strategy, battery concerns are a thing of the past. No matter of the behaviour of the car user. To prove a point you can leave the car with the high beam on and the stereo at full blast in the evening, without the engine running. Wake up in the morning, open the car door, start the engine and drive away. Alternatively, leave the car for a couple of months, open the door, start the car and drive away.

  2. I guess we are both on the same track as the Chimera also has electronic circuitry. Being so small and light one could always take it out of the car for the winter and bring it in the house. The Chimera can be charged in only 10 minutes anyway. The One1 is a simply fantastic car worthy for anyOne lucky enough to reside in the most fashionable residence in the whole of New York: One57
