Koenigsegg Agera S Launched In Malaysia, RM5 Million Before Local Taxes
The Agera S has all the features and functions of the Agera R apart from the flexfuel capability. Still amazingly Koenigsegg has managed get 1100 nm torque and a full 1030 hp when the car is run on 98 octane RON or 93 octane DIN. In order to give the Agera S maximum flexibility when it comes to power delivery, Koenigsegg has implement the latest technology when it comes to turbo materials and design. The reduce inertia of the turbine wheel and axle 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 S 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 road 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 S.
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 2014 Agera S 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 41%.
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 S 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 2014 Agera S 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 S make it truly unique. The normal Agera already has a level of performance that is out of this world. The Agera S manages to push the performance envelope just that little bit further.
Take action
Although sharing the same values and philosophies as previous Koenigsegg models, the 2014 Agera S takes the Koenigsegg experience to a completely new level.
Similar to all previous Koenigsegg hypercars, the new Agera S is the brainchild of Christian von Koenigsegg.
The Agera S sets new benchmarks for hypercars when it comes to control, handling, speed, comfort, practicality and sheer driving enjoyment, while combining these features with clean, efficient and beautiful design.
The Agera name set the tone for the new project. Agera means “to take action” in Swedish. It is also short for the ancient Greek word Ageratos which means “ageless”. These are both suitable meanings for a car that is building the future of Koenigsegg.
The design
The Agera S is designed with a minimalistic “less is more” philosophy in mind. This philosophy dictates that the shape of the car has to be purely functional, with no added features except those needed to meet regulations, or enhance safety, ergonomics, practicality or aerodynamics. We believe that if this philosophy is followed, the car will be as beautiful as it is purposeful. A good analogy is the evolution of the dolphin, a species that has had to meet similar criteria in order to reach its present configuration through the evolution of nature.
The Agera S has handsome proportions. It´s compact and muscular. Its timeless, efficient and distinctive shape is a true testament to good design. The original shape and concept of the Koenigsegg CC, created over 15 years ago, is still valid, fresh and highly competitive today. The Agera S manages to stay true to the 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 we develop and produce our own engines in-house. Most observers and/or competitors consider this to be more or less impossible, or way too expensive to even consider. Koenigsegg has proved them wrong, year after year.
Not only are the engines developed in-house, they also have class-leading characteristics in many important areas. They are the lightest and most compact hypercar engines in the world, weighing only 197kg complete with flywheel, clutch, dry sump system, Inconel exhaust manifold and turbo. The low engine weight is quite astonishing as the Agera S engine also has class-leading power and torque characteristics. The Koenigsegg 5 litre V8 bi-turbo engine develops 1030 hp on 98 octane RON or 93 octane DIN. The Agera S has over 1000 Nm of torque from 2700 rpm and 1100 nm from 4100 rpm, showing great flexibility.
These are extraordinary numbers considering the size and reliability of the engine and they are obtained with no sacrifice of either drivability or flexibility. This is truly downsizing without compromise. These characteristics make it one of the most flexible and easy-to-use hypercar engines in the world.
To give a hint of how different the Agera S engine is compared to other production car engines, it is easy to look at the Brake Mean Effective Pressure value (BMEP) in the cylinders during maximum power output.
The best production petrol engines from other leading manufacturers have a maximum BMEP of around 22 bar. The Agera engine has a BMEP of 29 bar, when running on 98 octane RON fuel.
This shows how extreme the Agera S engine is when compared to any other production engine in the world. The reason the Agera S can obtain such high cylinder pressures is due to some proprietary and critical factors, such as:
- The 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 that reduces TDC dwell time and thereby enables higher mean pressures without detonation.
- Exhaust manifold and intake plenum trumpets designed to ensure the absence of peak RPM resonance and back pressure.
- An efficient ejector pump system reducing the crankcase pressure and aerodynamic losses.
Koenigsegg engines are also constructed to meet all required emission standards around the world. This is nothing short of astounding, given their size and power output.
Furthermore, 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 emissions (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 Agera S engine is – especially given its extreme performance.
The Agera S engine is built to comply 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, have been lowered. This is an astonishing feat for a 1050 hp hypercar. Turbo response is of vital importance when it comes to driving pleasure and the possibility of controlling massive amounts of power. Koenigsegg has coupled the latest generation turbo technology with a patent-pending and proprietary response/back pressure reduction system, invented by Christian von Koenigsegg, to really give the Agera S engine a competitive edge.
The large air-to-air intercoolers on both sides of the engine exchanges 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 dry sump lubrication in order to lower the engine as far as possible in the chassis whilst maintaining full control of the crankcase oil, even given the massive g-forces that can be generated.
The large 80-litre fuel tank ensures a long driving range due to the relatively low average consumption. The Agera S follows the previous generations of Koenigsegg vehicles with its fuel tank being well protected, built centrally into the carbon fibre monocoque chassis. Since the fuel is placed centrally within the car, the weight distribution does not change regardless of whether the tank is full or empty. Thanks to the safe fuel tank position, the challenging US high-speed rear impact test was passed at the very first attempt.
The Agera S has four intelligent 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 element in the Agera S achieving its remarkable emissions 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 have been examined carefully in order to maintain Koenigsegg’s typical, thunderous growl.
The transmission
The newly developed 7-speed gearbox for the Agera S 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 chose to develop a new gearbox type in partnership with Cima, one that enables the use of a combination of both a dry and wet clutch systems 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 upshift in order to slow down the input shaft as the gears are changed and prior to the normal synchronization. This cuts the synchronization time by two thirds as the gear is pre-synchronized. 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 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 81kg, 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, thereby giving an excellent central mass position and maintaining neutral behaviour in extreme conditions.
Koenigsegg E-Diff
The Koenigsegg Electronic Differential (E-Diff) is both lighter and faster when compared to traditional E-Diff solutions. The difference lies in the fact that Koenigsegg has retained a limited slip differential with plates and ramps that have a built-in amount of analogue limited slip functionality. Consequently, the active hydraulic element can be 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.
Koenigsegg has therefore obtained one of the lightest and fastest E-Diff solutions on the market. The algorithms that control the E-Diff – also developed by Koenigsegg – take inputs from throttle angle, g-force, steering wheel angle, yaw angle, car speed, engine rpm, selected gear, plus the prevailing weather conditions.
The manner in which the car analyses and then reacts to this data makes the Koenigsegg E-Diff unique. It ensures that the Agera is very safe on the limit, with improved performance and feel.
The Koenigsegg E-diff works in harmony with a new traction control system, the fastest reacting system in the industry with auto-adapt functionality for different road conditions and driving styles as well as a number of manual settings.
The chassis
The Agera S´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 level of stiffness, measures at 65.000 Nm/deg. It weighs just 70kg, including the integrated fuel tanks.
The result of constant weight saving exercises is a dry weight of only 1330kg, making the Agera S the lightest, fully homologated hypercar presently in production.
