THE DESIGN
The Agera is designed with the minimalistic "less is
more" philosophy in mind. This philosophy means that the shape of the
car has to be purely functional with no added features except those
purely needed to meet regulation, added safety, ergonomics, practicality
and aerodynamics. We believe that if this philosophy is followed, the
car will also be beautiful as it is purely purposeful. A good analogy is
the evolution of a dolphin that has had to meet similar criteria in order to reach their present configuration through the evolution of nature.
The
Agera is proportionate, compact and muscular. Its timeless, efficient
and distinctive shape is truly a testament to time. The original shape
and concept of the Koenigsegg CC, created 15 years ago, is still valid,
fresh and highly competitive today. The Agera manage to stay true to the
original philosophy, shape and size of the original CC. At the same
time, it looks, feels and performs like something belonging to the
future.
THE ENGINE
Koenigsegg differs from other low volume
hypercar manufacturers by the fact that Koenigsegg develops and produces
its own engine in-house. This is, by most observers and competitors,
deemed as more or less impossible or way too expensive to even consider.
However,
year after year Koenigsegg has proved them wrong. Not only are the
engines developed in-house, they also have class leading characteristics
in many important areas. To mention a few: Lightest and most compact
hypercar engine in the world, weighing only 197 kg complete with
flywheel, clutch, dry sump system, Inconel exhaust manifold with turbo.
The low engine weight is quite astonishing, as the Agera engine also has
class leading power and torque characteristics. To give an example, the
Koenigsegg 5 litre V8 bi-turbo engine develops more than 900 hp on 95
octane regular fuel, and more than 1100 hp on E85 bio fuel. The Agera
produces over 1000 Nm of torque from 2500 rpm and in the Koenigsegg
Agera R format the engine has a peak torque of 1200 Nm over a 3300 rpm
rev range, showing great flexibility.
These are extraordinary
numbers considering the size and reliability of the engine without
forsaking drivability or flexibility. This is truly downsizing, without
drawbacks. These characteristics make it one of the most flexible and
easy to use hypercar engines in the world.
The Agera engine has a
BMEP of 28 bar running on 95 octane fuel and the E85 Bio fuel
Koenigsegg Agera R engines has an astonishing BMEP of 30 bar. These
numbers show how extreme the Koenigsegg engines are compared to any
other production engine in the world. The reason why Koenigsegg can
obtain such BMEP figures is due to some proprietary and critical
factors:
- A unique shape of the combustion chambers, improving the resistance against detonation.
- High cylinder head clamp load, enabled by a specially designed
engine block. This has proven to give a zero failure rate to combustion
overpressure, even considering the extreme cylinder pressures.
- A unique engine block design, where the cylinder sleeves are used to further stiffen the aluminium block.
- A connecting rod design reducing TDC dwell time and therefore enabling higher mean pressures without detonation.
- Exhaust manifold and intake plenum trumpets designed to ensure absence of RPM peak resonance and back pressure.
- An efficient ejector pump system reducing the crankcase pressure and aerodynamic losses.
The Koenigsegg engines also meet all the required emission standards
in the world. This is nothing short of astounding, given their size and
power output.
Koenigsegg has its own engine lab, with simulation
programs, rapid prototyping machines, engine and chassis dynamometers,
and a 1.7 km test track adjacent the factory enabling Koenigsegg to take
the cars to 0-320-0 km/h at any time. Furthermore, a 25 minute drive
away from the Koenigsegg Factory there is Knutstorp Racetrack, which is
described by many as a miniature Nordschleife. Here Koenigsegg can put
the engine and car through serious testing and make sure they work in
perfect harmony. This gives Koenigsegg unique possibilities to develop
technologies normally exclusive to much larger companies.
No
other production engine in the world, regardless of car type, has the
same amount of power potential compared to its EU cycle average CO2
emission(310g of CO2) or cycle fuel consumption( 14,7 litre per 100 km /
16MPG). However, what makes Koenigsegg most proud is how drivable,
smooth, responsive, torquey and reliable the engines are - especially
given their extreme performance.
The Agera engine complies with
the most stringent environmental regulations in the world, EU5 and LEV2,
and delivers a significant power increase compared to previous
Koenigsegg engines.
Fuel consumption, and thus CO2 emissions, has
been lowered. This is an astonishing feat for a 900+ hp hypercar. Turbo
response is of vital importance when it comes to driving pleasure and
the possibility to control massive amounts of power. Therefore
Koenigsegg has joined forces with Borg Warner and adapted to the latest
technology when it comes to turbine materials. The Koenigsegg Agera R
turbines are made from a material called Gamma-Ti which is an inter
metallic compound comprised of aluminium and titanium. This new material
drastically reduces the inertia of the turbine wheel and axle and
therefore gives improved response. Furthermore Koenigsegg has coupled
this latest generation turbo technology with patent pending and
proprietary response/back pressure reduction system, invented by
Christian von Koenigsegg to really give the Agera engine a competitive
edge when combining maximum power while complying with the strictest
emission regulations in the world.
Furthermore the large air to air
intercooler on the left side of the engine sucks enormous amounts of
fresh air, eliminating the need for water in the intercooling system,
thereby saving weight and avoiding heat soak issues, during extended
performance driving.
Following the Koenigsegg tradition the engine
has a dry sump lubrication in order to lower the engine as far as
possible in the chassis and have full control of the crankcase oil even
given the massive g-forces involved.
The large 80-litre tank
ensures long driving range, due to the relatively low average
consumption. The Agera follows the previous generation Koenigsegg and
has its fuel tank well protected, built-in centrally into the carbon
fibre monocoque chassis. Since the fuel is centrally placed in the car,
the weight distribution does not change regardless if the tank is full
or empty. Thanks to the safe fuel tank position, the challenging US high-speed rear impact test, was passed at first trial.
The
Koenigsegg Agera R has four intelligent bio fuel grade return-less fuel
pumps to deliver the correct amount of fuel at any given time. This
reduces the energy needed to operate the fuel pumps and eliminates the
waste of excessive fuel transport.
The inconel/titanium patent
pending exhaust system is key in order for the Agera to achieve its
remarkable emission and power levels. The exhaust system uses a
completely new principle created by Christian von Koenigsegg. The new
technology drastically reduces back pressure and gives earlier catalytic
light off than any other turbo exhaust system. At the same time the
acoustics of the exhaust has been examined carefully in order to
maintain the typical Koenigsegg thunderous growl.
THE TRANSMISSION
The
newly developed 7 speed gearbox for the Agera features a world's first
dual clutch system for a single input shaft gearbox. In order to keep
the gearbox light, compact strong and reliable, Koenigsegg together with
Cima chose to develop a new gearbox type that enables the use of a
combination of a dry and wet clutch system, in order to get class
leading shift times. First there is the normal twin disc dry clutch that
operates in a traditional fashion. Then there is a hydraulically
operated wet clutch-brake inside the gearbox that is engaged during each
up shift in order to slow down the input shaft, simultaneously as the
gears are changed and prior to the normal synchronisation. This cuts the
synchronisation time by two thirds, as the gear is presynchronized. The
result is a very sporty, smooth and extremely fast shift. Compared to a
traditional DCT system, this gearbox is lighter, smaller, has less
moving parts and gives a more distinct shift feel, with almost no
interruption to the acceleration. Furthermore, the electro hydraulic
shift mechanism actuates the shift forks directly with no intermediate
mechanical parts. This brings down the inertia of the shift mechanism
and any potential slack is minimized since the shortest possible path of
engagement is achieved.
The entire transmission weighs only 81
kg, which is by far the lightest 7 speed Hypercar transmission in the
world. The transmission can also be set in full auto mode.
The
small size and very low weight, considering the longitudinal 7 speed
layout, made it possible to maintain the shortest in class rear
overhang, and thereby excellent central mass position and neutral
behaviour in extreme conditions.
Koenigsegg E-Diff
The
Koenigsegg Electronic Differential (E-Diff) is lighter and faster,
compared to traditional E-Diff solutions. The difference lies in the
fact that Koenigsegg has retained a limited slip differential with
plates and ramps with a built-in amount of analogue limited slip
functionality. This means that the active hydraulic element can be
smaller, more compact and therefore faster and lighter compared to
traditional E-Diff solutions. The analogue part of the functionality
also has zero processing time as it reacts directly. The analogue system
is supplemented by a digital active system.
The way Koenigsegg
has obtained one of the lightest and fastest E-Diff solution on the
market. Furthermore the Koenigsegg developed algorithms that control the
E-Diff, takes input from; throttle angle, g-force, steering wheel
angle, yaw angle, car speed, engine rpm, selected gear, plus weather
condition.
The way all this data is analysed and how the car reacts
to this data also makes the Koenigsegg E-Diff unique and that makes the
Agera very safe on the limit and improves performance and feel.
The
Koenigsegg E-diff works in harmony with the new traction control system
that is the fastest reacting in the industry, with auto adapt
functionality to different road conditions and driving styles as well as
several manual settings.
THE CHASSIS
The Agera´s unique
carbon fibre monocoque chassis is designed to achieve its maximum
stiffness without a roof, as the roof is detachable and stow-able in the
front of the car. This in itself is an unusual feature for such a
compact Hypercar.
The Koenigsegg carbon monocoque chassis has an
astonishing stiffness of 65.000 Nm/deg and only weighs 70 kg including
the integrated fuel tanks.
The result of constant weight saving
exercises is a dry weight of only 1330 kg making the Agera the lightest
fully homologated Hypercar presently in production.
THE SUSPENSION
The
suspension geometry of the Agera was designed to further enhance the
award winning behaviour of the CCX. The Agera track is wider at the
front compared to the rear of the car, compensating for the narrower
front tires and giving the car a square stance of 2 meters in both the
front and the rear.
In typical Koenigsegg tradition, the Agera
has the longest wishbones of all hypercars presently in production. Long
wishbones have several advantages - for example: less track width
deviation during wheel movement or cornering and improved geometry over a
longer wheel stroke. This is one of the reason why F1 cars have very
long wishbones. The wishbones are produced from seamless aeronautical
chrome-molybdenum tubing, in order to minimise weight in combination
with maximum strength and stiffness.
The extremely strong and
light uprights are machined from 7075-T6 aeronautical grade aluminium,
and contains 240 mm SKF dual angle contact bearings, normally only found
on Lemans prototype cars. The very large bearings contribute to the
overall stiffness of the wheel assembly and therefore give better
control, handling and comfort. The uprights have large 4.5" diameter
carbon fibre cooling ducts for the brake discs in order to maximise
brake cooling.
Brakes
The Agera is equipped with the
absolutely latest ABS technology and is based upon, a very lightweight
and performance oriented, racing ABS system. The system makes it
possible for the ABS function to react to differently depending on
performance mode. Furthermore the ABS braking system operates on massive
392×36 mm and 380×34 mm ventilated and drilled ceramic discs, for
unparalleled braking performance and zero fade regardless of track or
road condition.
RTD (Rear Triplex Damper) Suspension
Christian
von Koenigsegg has invented and pioneered a new type of rear suspension
system for a road car. The Agera 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 extra spring and
damper works in series with the normal spring 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.
Furthermore the RTD system 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 than anti-squat.
By adding the RTD system,
Koenigsegg can maintain true suspension geometries for handling, but
still have the anti-squat feature and harvest other new found benefits.
As the RTD system compliments the normal dampers and springs, these can
be made lighter. Hence, the added benefit does not significantly affect
the overall system weight.
DEDICATED MICHELIN TIRES
Koenigsegg
continued its long standing partnership with Michelin in the tire
development for the Agera. Hence the Agera features specially developed,
latest generation Michelin Super sport tires.
Due to the tires,
advanced suspension and aerodynamics, the Agera achieves lateral
accelerations up to 1.6 g in dry conditions with improved handling in
wet.
The new tires were developed for the Agera through testing at the Michelin Ladoux test centre in France.
The
tires fitted to the Agera are rated for speeds over 420 km/h making it
the highest top speed rated tire in the world, whilst offering cup tire
levels of grip and outstanding wet performance , all in one package.
Koenigsegg are very proud of being a selected development partner of Michelin.
VGR - Vortex Generating Rim spokes
The
Koenigsegg VGR wheels are not only for looks. They are real air
turbines, increasing the down force of the car by measurable amounts and
improve brake cooling. All four wheels are individual so that turbine
blades always face the correct direction for extraction. Given that the
offset and width is different front to rear, all four wheels have their
unique design. The VGR wheels are forged and then fully machined to the
final shape. Due to the forging and machining process all excess
material has been removed minimising weight, whilst displaying
outstanding levels of stiffness.
THE AERODYNAMICS
The
Aerodynamics of the Agera has been honed and perfected over many years
in CFD and wind tunnel in order ensure best possible outcome. Even with
the massive dynamic rear wing, the drag of the Agera is only Cd 0.33, in
high speed mode and Cd 0.37 in track mode. Even though the Agera is a
full 2 meters wide, it only has a frontal area of 1.87 m2. This results
in a Cd*A value of only 0.62 and thus a theoretical top speed of around
440 km/h (Agera R), given the gear ratio and power available. All Agera
models are limited to 375 km/h in standard mode, but can be unlocked by
Koenigsegg for shorter periods of time, if all necessary conditions are
met, such as road condition, tire wear, service level of car etc. The
car is set in full speed mode by unlocking the top speed mode in the
Infotainment system.
The two large side air intakes greatly add
to the Agera´s high speed stability as they ensure that the pressure
point of the car is behind the mass centre of the car. This makes the
car more directionally stable with increasing speed. This is a crucial
safety feature when it comes to driving at extreme speeds. Great care
has been taken that the car also is stable under high speed braking. The
front splitter and rear diffuser has been designed and optimized with
this in mind.
For maximum performance and safety it is important
that the down force stays as constant as possible even in yaw
situations. Therefore the rear diffuser was developed and evaluated
specifically to give substantial down force even at wide yaw angles.
Dynamic rear wing
Hypercars
of today generate massive amounts of down force in low to medium speed
and less down force in very high speed, in order not to overload the
tires and not to create 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 the above described 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 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.
Furthermore, an interesting
multifunction feature of the adaptive wing is that the pylons for the
wing also act as air extrusion channels. The air channels goes 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 and giving more
low drag down force.
THE INTERIOR
The interior of the Agera is
like no other car. No other materials than those deemed worthy by
Koenigsegg are allowed in the interior. This means that what you get to
touch and see inside the Agera is only aluminium, carbon fibre, precious
metals, alcantara and aniline leather. All switch gear is highly
bespoke and features wonderfully unique solutions, as for example the
Koenigsegg Ghost light, that make solid aluminium buttons gleam with LED
powered symbols appearing out of nowhere. A world first in the car
industry. The illumination shines through the billet aluminium buttons
and surfaces by way of almost invisible micro holes, creating excellent
visibility of the symbols as well as a very clean and stylish
appearance, framed by an all-new carbon fibre centre console and tunnel
assembly.
The new super light full carbon airbag steering wheel
incorporates many vital functions directly in front of the driver.
Similarly to the CCX, the shifting paddles are mounted directly on the
steering wheel to enable shifting without taking your hands off the
steering wheel during hard cornering.
The central high-definition
touch screen infotainment system controls the audio functions,
satellite navigation, Bluetooth phone and secondary functions such as
performance meters and car telemetrical data.
The very comfortable
and optionally heated carbon seats are great for long journeys but also
give excellent lateral support when needed.
The Interior of the
Agera is truly minimalistic and efficient in the purest Swedish sense.
Nothing in the interior is there only to add visual drama; instead
everything is there for a functional purpose. According to Koenigsegg,
this is the essence of beauty, as it follows a less is more philosophy
that embodies every engineering aspect of the Agera.
CI - Configurable Instruments
The
CI is specifically developed for the Agera by Koenigsegg. It features a
unique and configurable interface that can be adapted to driver
specific demands. As it is connected to the cars CAN bus system it
freely communicates with the infotainment screen and all other functions
in the car.
By pushing the left stalk button, different priority
graphics can be chosen, depending on need. For example in track driving
mode, there is a focus on; RPM, pressures, temperatures, lap times, and
g-forces. Compared to GT mode, where: car speed, auto shift, satnav,
power, music etc is prioritized.
THE LUGGAGE SPACE
The luggage
space is something Koenigsegg is very proud of. It is the largest
luggage compartment in the hypercar world, with a space of over 120
litres. It is so well shaped that it actually can fit the one piece
Agera roof/hardtop, meaning the driver can choose to go open or closed
at any given time during a longer trip. Given the fact that Koenigsegg
has engineered the roof to fit the car, it is actually also possible fit
a set of golf clubs. This is unheard of in the hypercar world. Given
the high comfort level and the large luggage space, the Agera can truly
been seen as one of the first GT hypercars.
Custom Carbon fibre Thule Lightning Roof Box
At
the 2011 Geneva Motor show, Koenigsegg presents the Koenigsegg winter
package - the first lifestyle packages offered from Koenigsegg. The main
element of this package is the exceptional Lightning Roof Box System.
The
Lightning Roof Box is developed together with the Swedish rack and roof
box manufacturer Thule. The high performance lightweight box is made
completely from carbon fibre and has been through several iterations of
CFD simulation to ensure it is safe up to 300 km/h, making it the
fastest roof box in the world.
The roof box, which has an
incorporated roof panel, replaces the normal roof in under 10 minutes.
The standard roof is then stored in the luggage compartment in the front
of the car, so that when the driver arrives to his destination, the
roof box can be quickly removed and the normal roof can be put in place
for a more elegant look.
The Lightning roof box truly enables the
driver to use the Agera for longer trips with massive luggage. This
gives a whole new spectrum of hypercar utilization.
The winter
package also includes Michelin snow tires on forged Koenigsegg wheels
and custom designed Koenigsegg skis from the Swedish high end ski
manufacturer, Extrem.
Part of the winter package is also a Swedish
winter resort experience in Åre - Sweden's most popular skiing resort
and the place of manufacture of the Koenigsegg skis.
During the stay
in Åre, the Koenigsegg customers will be fitted for their skis and they
can witness first hand when they are being hand made in "Åres
skidfabrik", a state of the art ski production plant.
While their
skis are being made, they will be checked into the delightful
Copperhill Mountain Lodge that is towering snow-capped forests and
sparkling frozen lakes.
The following day the skis are ready for use
and Åre´s many and varied ski slopes are available for test runs, in
direct access from the Copperhill Mountain Lodge.
Together with the Golf club options this marks the start of the Koenigsegg extended lifestyle program for Koenigsegg cars.
We
would also like to thank Full Tilt, Houdini Sportswear, Sweet
Protection, Sport Lodge'n Trysil and Moods of Norway, for assisting us
in creating the winter experience at the Geneva motorshow.
THE ELECTRONICS
Not
only does Koenigsegg develop their own engines, but also many of the
electronic control units, CAN protocols, and management strategies are
developed in-house. If you would look closely at many of the circuit
boards in the car, inside the control units, you will find the name
Koenigsegg in scripted directly on the circuit boards.
Of course
there is no self fulfilling need to develop so many critical items
in-house, unless it gives the car a competitive edge doing so. This is
actually the main reason for Koenigsegg doing it. This, for example,
gave Koenigsegg the possibility to pioneer the CCXR and Agera R - the
two first environmentally conscious hypercars in the world.
An
example of this development is In the Semiconductor Electric Control
Central. The ECC controls most of the electronic functions in the car.
Most physical fuses or relays have been replaced by software controlled
semiconductors which are configurable in function and enable monitoring
all power and threshold values. The ECC communicates via CAN with the
infotainment system in order to display necessary information to the
driver. For example if a door is open, a lamp is broken, or not all roof
locks are tight in place, information will appear on the instruments as
all electrical functions are controlled and monitored by the ECC.
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.
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.
