Koenigsegg One:1 Exceeds World Speed Records - In Practice

Koenigsegg stunned the world in September 2011 when it set a Guinness World Record time of 21.19 seconds for the 0-300-0 km/h run in the Koenigsegg Agera R. The time achieved by the Koenigsegg One:1 cuts a full 3.24 seconds from what was already considered to be an unbeatable time.

The record-beating run was one of a series of runs conducted in a practice session at the Koenigsegg test track in Ängelholm, Sweden. The session was conducted on Monday, June 8 2015, from 6 pm to 10 pm. The driver was Koenigsegg factory test driver, Robert Serwanski.

This session follows recent track testing that revealed impressive performances and unofficial production car lap records at Suzuka Circuit and Spa-Francorchamps.

Data
Data was collected using the industry-standard VBox data recorder. The stage data for the record-beating run is as follows:
0-300 km/h: 11.922 seconds
300-0 km/h: 6.032 seconds
0-300-0 km/h: 17.95 seconds

0-200 mph: 14.328 seconds
200-0 mph: 6.384 seconds
0-200-0 mph: 20.71 seconds

It should be noted that this run was just one of many in the four-hour session and that faster individual stages, e.g. 0-100 and 100-200, were recorded through the session. In fact, if we piece together all the fastest individual acceleration and deceleration stages from the day, the theoretical 0-300-0 km/h time would be a staggering 17.49 seconds.

Note, too, that the One:1 development car is actually around 50kg heavier than customer cars due to the roll cage and other weight savings that were made to customer cars in series production. The roll cage in our One:1 development car is there for safety reasons. Our development car is pushed above and beyond what has been asked of any other production car in history and we have to protect our driver when we ask him to drive so far beyond what are perceived to be ‘normal’ limits.

A roll cage is an option for the One:1 and Agera RS vehicles. We think that an even lower time is a distinct possibility with the Koenigsegg One:1 and we will do our best to schedule another session in the near future.

Conditions
The Koenigsegg test track is a straight 1.5km runway surface with no gradient along the length of the track. The track was dry and the run shown in the video was conducted at 9:53 pm on June 8, 2015.

The One:1 was fitted with Michelin Pilot Sport 2 Cup tires, which are the same tires fitted to the car upon delivery to customers.

The air was very calm and virtually wind-free at the time of the run shown in the video.

How 0-300-0 km/h works
The 0-300-0 run is a test of the vehicle’s mechanical and technical capability. This test is purely designed to see how quickly the car can accelerate from 0 to 300 km/h and decelerate from 300kmh to 0. It is typically done using two discrete measurements - acceleration and deceleration - which may be from the same run, or they may be from different runs within the same session.

For the time that we have published today, both the acceleration time and the deceleration time come from the same run. It is not unusual, however, to have them sourced from different runs within the same session, which would have resulted in an even lower number.

As you watch the video, you will see that Robert does not simply go to 300kmh and then apply the brakes. That would be a test of the driver’s reaction times rather than a pure test of the vehicle.

Robert accelerates past 300 km/h to 340 km/h and then applies the brakes. This is partly to exceed 200mph, the measurement of which was a secondary goal in this session, and also to ensure that full brake pressure (both mechanical and aerodynamic) is in place by the time the car has decelerated to 300 km/h.
