THE R WITH MORE OOMPH! THAN BEFORE

The 2013 Agera R is the result of Koenigseggs endless persuit for perfection.


The 2013 model features new Aircore hollow carbon fiber wheels, uprated power and enhanced aerodynamics. The Agera R has an incredible top
speed of approximately 440 km/h (273  mph).
Recent Records for the Agera R: 0-300 km/h in 14.53 sec, 300-0 km/h in 6.66 sec, 0-200 mph in 17.68 sec, 200-0 mph in 7.28 sec.
The Agera R is the only roadster Hypercar with a detachable and stowable hardtop, bringing the best of two worlds. This in combination with
120 litres of luggage space, truly combine extreme performance with everyday usability.

The 2013 Agera R has all the features and functionalities of previous year models, but also features new and unique solutions to enhance
performance and visual appearance even further.
Example of these enhancements are; Visible carbon area on the front bonnet and bumper, new  front side winglets, revolutionary Aircore
carbon fiber wheels, the new Aero exhaust, the increased power and the raised rpm limit.
Koenigsegg was the first Hypercar manufacturer to take steps toward green technology with the release of the biofuel CCXR in 2007. The
Agera R, based on the highly competitive Agera, follows in the footsteps of the CCXR as it also runs on E85 biofuel.
Among many differences to the standard Agera, the Agera R has an upgraded fuel and engine management system with enough flow capacity to
generate 1140 hp and 1200 nm of torque on E85 and E100 biofuel. As there is less energy content per given volume in these biofuels compared
to normal petrol, the fuel-system has to manage a flow that is similar to a 2000hp petrol engine, which means that the Agera R’s return-less
fuel system has the highest capacity of any car presently in production.
As the Agera R is a flexfuel car, it can also be run on normal petrol. As 95 octane fuel has less octane than E85, the power is reduced to
960hp with 1100nm of torque due to the boost pressure and ignition timing being altered to match the fuel characteristics.
In order to give the Agera R maximum flexibility when it comes to power delivery, Koenigsegg has implement the latest technology when it
comes to turbo materials and design. This reduces the inertia of the turbine wheel and axle and therefore gives improved response.

Triplex rear suspension
Christian von Koenigsegg has invented a new type of rear suspension system for a road car – Triplex rear suspension. The Agera R comes with
\the Triplex rear suspension system as standard and therefore has a shock absorber and spring connecting the right and left rear wheel. This
system gives unique benefits as the two rear wheels can influence one another when desired.
There are multiple benefits of this system. For example, the Triplex system works in series with the normal springs and dampers, allowing their
spring and damping rates to be lowered. This results in increased comfort and better handling on rough and wet surfaces without compromising dry
track handling.
The Triplex system also has an anti-squat effect. Traditional anti-squat systems are designed into the geometry of the suspension. These systems
do not add any components or weight. However they compromise the geometry of the suspension for other aspects of handling aside from anti-squat.
By adding the Triplex system, Koenigsegg can maintain true suspension geometries for handling, but still have the anti-squat feature and harvest
other new found benefits. As the Triplex system compliments the normal dampers and springs, these can be made lighter. Hence, the added benefit
does not significantly affect the overall weight of the car’s suspension.

Dynamic rear wing
Hypercars of today generate massive amounts of downforce at low to medium speed and less down force at very high speed. This is so as to avoid
overloading the tires and creating too much drag. Most hypercars therefore have heavy, hydraulically operated wings and flaps to cater for this
need.
Koenigsegg however, following the “less is more” philosophy, has designed a dynamic system to that take care of these needs.
The most visual and obvious part of this system is the new dynamic rear wing. The wing changes its angle of attack, not with the help of hydraulics,
but with the pressure of the wind. It is therefore dynamically controlled by the vehicle speed, or wind resistance, at any given moment in time and
thus actually compensates for headwind or tailwind at the same given speed. This is an intelligent way of dealing with adaptive aerodynamics as the
system becomes lighter, less complex and more intuitive compared to heavy and complex hydraulics systems. Koenigsegg had to work heavily with CFD
in order to create the dynamically controlled adaptive aerodynamics of the Agera R.
An interesting additional feature of the adaptive wing is that the pylons for the wing also act as air extrusion channels. The air channels go from
the engine bay to the back of the pylons, thereby creating an air passage. This causes a venturi effect from the air rushing past the pylon, evacuating
hot engine bay gases, reducing pressure in the engine bay and increasing the flow of cooling air through the side radiators. This also means that the
pressure under the car is reduced, giving more low drag down force.



Aircore Carbon fiber wheels
The 2013 Agera R features the world's lighest and strongest Hypercar wheels, developed and produced by Koenigsegg. What makes this wheel truly unique
is that the spokes and centre part of the wheel are completely hollow and made out of carbon, in one piece - together with the rest of the wheel.
This design demanded that Koenigsegg come up with a novel way of producing a one-piece hollow carbon construction, something much more complex than
what has been allowed previously. The only metal part in the Koenigsegg Aircore carbon fiber wheel is the checkvalve for filling up the tire. Apart
from this tiny part, the whole wheel is only  made from carbon. Given its unique design, the wheel's strength is much higher than any forged aluminium
wheel, but at the same time it delivers a weight saving of around 40%.
This drastic reduction in weight brings massive benefits when it comes to performance. Everyone understands that unsprung weight should be keept at a
minimum in order to have maximum performance. What is not so well understood is that the rotational mass should be kept to a minimum. Every time the
car accelerates or brakes this rotational mass works against the objective of quick acceleration or short braking distance. In addition, the steering
feel and keenness is affected by the rotational mass, as the rotational mass acts as a gyro, counteracting turning. Simply put, reducing the rotational
mass not only gives less unsprung weight and a lighter car, but it also increases the dynamic power that goes into the ground while accelerating or
braking. Reducing the rotational mass gives similar effect as equipping the car with larger brakes and more horsepower on top of saving weight and
improving handling.
The Koenigsegg Aircore Carbon Wheel is a fantastic solution for overall performance improvement. Koenigsegg truly reinvented the wheel.

Front winglets
The Agera R comes standard with Koenigsegg´s latest carbon front winglets mounted on the radiator outlets. These winglets not only give 40kg more
down force at 250km/h, but also reduce drag, making them a true win-win installation.

Aero exhaust
The 2013 Agera R comes equipped with a new one piece exhaust outlet. Not only is this outlet lighter, it is also shaped to improve underbody air
release and work in conjunction with the Carbon air diffusors which flank the exhaust outlet.

All these added features to the Agera R make it truly unique. The normal Agera already has a level of performance that is out of this world.
The Agera R manages to push the performance envelope just that little bit further.
