The Agera R's Engine
Koenigsegg differs from other low volume
hypercar manufacturers by the fact that Koenigsegg develops and produces its own
The Koenigsegg 5-liter bi-turbo engine in the Agera R
features class leading power and torque characteristics at 1115 hp and 885 lb-ft
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.
To give a
hint of how different the Agera engines are compared to other production car
engines, it is easy to look at the BMEP value (Brake Mean Effective Pressure) in
the cylinders during maximum power output. The best production diesel and petrol
engines from other leading manufacturers have a maximum BMEP of around 22 bar.
The Agera engine has a BMEP of 28 bar running on 95 octane fuel and the E85
Bio fuel 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, such as:
- A unique shape of the combustion chambers, improving the resistance
- High cylinder head clamp load, enabled by a specially designed engine
block. This has proven to give a zero failure rate to
overpressure, even considering the extreme cylinder pressures.
- A unique engine block design, where the cylinder sleeves are used to
further stiffen the aluminum 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
The Koenigsegg Agera R 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.
The 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.
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 Agera R
turbines are made from a material called Gamma-Ti which is an inter metallic
compound comprised of
aluminum 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
The aerodynamics of the Agera R 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
78.7 inches (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 273 mph
(440 km/h) for the Agera R version, given the gear ratio and power available.
Custom Carbon-Fiber 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 fiber and has
been through several iterations of CFD simulation to ensure it is safe up to 186
mph (300 km/h), making it the fastest roof box in the world.
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
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
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 Are - Sweden's most popular skiing
resort and the place of manufacture of the Koenigsegg skis. During the stay in
Are, the Koenigsegg customers will be fitted for their skis and they can witness
first hand when they are being hand made in "Ares 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 snowcapped
forests and sparkling frozen lakes. The following day the skis are ready for use
and Are´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
