Koenigsegg Agera R crashed in China

Article by Christian Andrei, on December 1, 2015

There was a recent report about a Koenigsegg Agera R being involved in an accident in China. Although, it was initially difficult to get more details on the model of the car involved, it was later confirmed that a chassis #082 Koenigsegg Agera R had crashed in Chongqing city in China.

The Swedish hypercar allegedly was being driven at a high speed when the driver suddenly lost control. The aerial photos of the incident show evidence of fluid around fifty metres on the highway’s right side with the car coming to a halt in proximity to the central reservation.

In the photos, it appears that no other vehicles have been damaged but this has yet to be confirmed. This particular model was probably from the first batch of China’s imported Koenigsegg Agera units and one that served as a model in the early promotional pictures used by Koenigsegg.

It is believed that the importer FFF Automobile used it largely for advertisement. Koenigsegg is widely different from other low volume hypercar manufacturing units because the company creates and produces its own in-house engine.

This engine production concept is considered impossible or too expensive a task by most of its competitors and observers in the auto manufacturing industry. But Koenigsegg has proved its engine production strategy to be not only efficient but also featuring the best parameters.

The in-house developed engines have high quality features. For instance, weighing extremely light at 197 kg with the flywheel, clutch, dry sump system, Inconel exhaust manifold with turbo, it is one of the most compact and lightest hypercar engines.

In spite of its leading power and torque, the engine manages to stay surprisingly light. The Koenigsegg 5 litre V8 bi-turbo engine produces 900 hp on 95 octane regular fuel and delivers more than 110 hp on E85 bio fuel. High flexibility is demonstrated in the fact that the Agera delivers over 1000 Nm torque from 2500 rpm whereas in the Agera A, the engine produces a peak torque of 1200 Nm over a 3300 rpm range.

These figures are extremely astonishing if one considers how this lightweight and efficient engine does not compromise on the driving experience and flexibility. The size and weight parameters have been brought down but without any disadvantages.

Thus, it easily comes out at the top of its class when it comes to handling. In fact, it’s among the most flexible hypercar engines in the world. Another primary feature that puts the Agera engines in a different class is its BMEP (Brake Mean Effective Pressure) value in the cylinders while giving maximum power output.

A maximum of around 22 bar is reached by most diesel and petrol engines. But for Agera, the BMEP is valued at 28 bar when using 95 octane fuel whereas for the E85 Bio fuel Koenigsegg Agera R, the BMEP reaches a surprising 30 bar.

These parameters make the Koenigsegg engines superior in comparison to other production engines in the world.

There is a wide variety of factors that work together to give such high BMEP figures for the Koenigsegg engine:

  • The engine’s block design where the aluminium block is stiffened even more by the cylinder sleeves.
  • The combustion chambers’ unique shape which improves resistance against detonation.
  • The specially designed engine block which enables a high cylinder head clamp load. As a result, the engine never fails when there’s combustion overpressure, not even during very high levels.
  • Exhaust manifold and intake plenum trumpets which are suitably designed to negate RPM peak resonance and back pressure.
  • Higher mean pressures without detonation, enabled by a drop in TDC dwell time because of the connecting rod design.
  • Reduction in the crankcase pressure and aerodynamic losses by an efficient ejector pump system.

Despite the small size, the Koenigsegg engines deliver a high power output and also fulfil all the needed emission standards worldwide, which make them all the more astonishing. The automobile manufacturing giant Koenigsegg has developed its own engine lab, with rapid prototyping machines, simulation programs, engine and chassis dynamometers, as well as a 1.7 km test track near the factory.

Thus, Koensigsegg cars can be driven from zero to 320-0 km/h at any time. A miniature Nordschleife has been created in the form of Knutstorp Racetrack which is just a 25-minute drive away from the Koenigsegg Factory.

It is here that the engine and car can undergo some serious testing to maximise their synchronisation. Such measures have resulted in the development of unique technologies by Koenigsegg which is usually the domain of much larger companies.

The Koenigsegg defies all other production engines when it comes to the 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).

In spite of all these high figures, the Koenigsegg proudly gives its owners a smooth, responsive, high torque and reliable driving experience combined with an extreme performance. The Agera engine is compliant with the world’s strictest environmental regulations like EU5 and LEV2.

It also comes with a high power increase as compared to the earlier Koenigsegg engines. The reduced fuel consumption is an added benefit for the 900+ hp hyper car. The manufacturer has taken good care of turbo response as it is of utmost importance to achieve driving pleasure and control.

Thus, Koenigsegg has joined hands with Borg Warner and has used turbine materials made with the latest technology. Gamma Ti is the turbine material which is an inter-metallic compound made of aluminium and titanium. The benefit of this material is that it brings down the inertia of the turbine wheel and axle and improves the vehicle’s response.

This all new turbo technology has been coupled by Koenigsegg with its patent pending and proprietary response/back pressure reduction system brought in by Christian von Koenigsegg. This has given the Agera engine the capability of delivering maximum power along with compliance with the most stringent emission regulations in the world.
