Koenigsegg Outperforms Other Production Car Speed Records

Koenigsegg has outperformed existing production car speed records during a practice session in the groundbreaking Koenigsegg One:1 Megacar, headlined by a 0-300-0 kmh time of just 17.95 seconds.
Koenigsegg stunned the world in September 2011 when it set a Guinness World Record time of 21.19 seconds for the 0-300-0 kmh 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 6pm to 10pm. 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 was collected using the industry standard VBox data recorder.
The stage data for the record beating run is as follows:
0-300 kmh: 11.922 seconds
300-0 kmh: 6.032 seconds
0-300-0 kmh: 17.95 seconds
0-200 mph: 14.328 seconds
200-0 mph: 6.384 seconds
0-200-0 mph: 20.71 seconds
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 pieced together all the fastest individual acceleration and deceleration stages from the day, the theoretical 0-300-0 kmh 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 the our One:1 development car is there for safety reasons. Their development car is pushed above and beyond any other production car in history and they have to protect their driver when they ask him to drive so far beyond what is perceived to be ‘normal’ limits. Their is a roll cage option for the One:1 and Agera RS vehicles.
Koenigsegg believe that an even lower time is a distinct possibility with the Koenigsegg One:1 and have promised to do their best to schedule another session in the near future.
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 9:53pm on June 8, 2015.
The One:1 was fitted with Michelin Pilot Sport 2 Cup tyres, which are the same tyres fitted to the car upon delivery to customers.
The air was very calm and virtually wind-free at the time of the run.
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 kmh 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.
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.
The test driver Robert accelerates past 300 kmh to 340 kmh 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 kmh.
The One:1 was introduced in 2014 and was built in 6 examples, plus one prototype during 2014 and 2015.
This was one of the most exclusive production car programs ever envisaged in the car industry.
The hp to kg curb weight ratio is an astonishing 1:1. This is the “dream” equation, previously thought impossible when it comes to fully road legal and usable sportscars. On top of this, the One:1 is the first homologated production car in the world with one Megawatt of power, thereby making it the world´s first series produced Megacar.
 This is why the car is called One:1.
The One:1 produces outstanding performance. The One:1 features new and unique solutions to enhance track performance without compromising top speed or everyday usability, with a stunning visual appearance to go with it.
Some of the features include a unique track optimized aero winglets, extended venturi tunnels and side splitters, Le-Mans inspired active wing configuration and optimized active under trim air management. Large air vents for improved cooling, roof air scoop to support the 1 Megawatt of power, 8250 RPM rev limit, complemented with Custom made Michelin Cup Tires, upgraded rear triplex suspension with carbon bevel springs and active shock absorbers and ride height, combined with upgraded revolutionary Koenigsegg Aircore carbon fiber wheels.
Koenigsegg was the first extreme car manufacturer to take steps toward green technology with the release of the biofuel CCXR in 2007. The One:1, a sibling of the highly competitive Agera R, follows in the footsteps of the CCXR as it also runs on E85 biofuel, race fuel or normal gasoline.
