Koenigsegg Agera R specs revealed! Still impressive!

Article by Christian Andrei, on March 22, 2011

Swedish supercar maker Koenigsegg has finally divulged the details of the Agera R and its high-speed ski box that were unveiled at the 2011 Geneva Motor Show. The Agera R can sprint from zero to 100 km/h (62 mph) in only 2.9 seconds, while going from zero to 200 km/h (124mph) takes just 7.5 seconds. 

Going from zero to 200-0 km/h (0-124mph-0) is accomplished in only 12.7 seconds, due partly to its ventilated carbon ceramic brakes. It also boasts of a top speed of over 420 km/h (261 mph).

Powering the Agera R is a twin-turbo 5.0-liter V8 engine that generates 1,115hp at 6,900 rpm when running on E85 ethanol. The car also runs on 95 octane petrol (940HP), or 98 octane (1,050HP).

The following are offered as standard: dual airbags, detachable storable hardtop with glass roof, power windows, adaptive rear wing, adjustable pedals and steering column, Agera stitching, adjustable seats in rake and length, carbon ceramic brakes with Sport ABS, hydraulic lifting system, power steering, power brakes, extra 4 point seatbelts for track use. satnav, Intelligent LifePo4 battery, MP3 player, USB connection, climate control, digital warning and info system, G sensor, alarm, tire monitoring system, silver key, leather carpets, roof storage bag, car cover.

Its options list includes visible carbon body, front winglets, rear view camera, the unusual ski box, Inconel exhaust system, winter wheel package and skis.


Koenigsegg has stood out in the modest volume hypercar industry because they actually design, improve and manufacture their engines. This practice has been seen and judged by others in the industry to be quite cost inefficient and impractical.

Nevertheless, Koenigsegg shows them up every year. Their independently developed engines outperform their competitors’ products especially in critical areas of measurement. Some of these include the current record for being the most lightweight and smallest hypercar engine, being just 197 kg including its flywheel, clutch, dry sump system and Inconel exhaust manifold with turbo.

The light weight is remarkable, given that the Agera engine boasts best-in-class power and torque as well. To illustrate, a Koenigsegg 5 litre V8 bi-turbo exceeds 900 hp using 95 octane petrol and 1100 hp with E85 bio fuel. The Agera generates above 1100 Nm of torque from 2500 rpm, while the Agera R’s maximum is 1200 Nm with a very flexible rev range of 3300 rpm.

This represents remarkable performance for an engine of its size, weight and dependability while still maintaining its drivable versatility. If there was such a thing as downsizing with no compromises, this would be it. Its top notch versatile performance is why it is such a usable hypercar engine.

A great way to see one of the Agera engine’s advantage over conventional automobile engines is in its cylinders’ Brake Mean Effective Pressure or BMEP at maximum power output. Top conventional engines have an approximate maximum of 22 bar BMEP.

Agera’s BMEP is 28 bar using 95 octane petrol. The Agera R tops out impressively at 30 bar on E85 Bio fuel. These measurements prove the superiority of Koenigsegg’s engines to all other engines being manufactured. Their engines achieve extraordinary BMEP values because of their trademarked technologies and key factors including:

  • Specially configured combustion chambers which reduce the chance for explosions.
  • A uniquely designed engine block that facilitates high cylinder head clamp load. This has been extensively tested to yield no failures from combustion overpressure despite very high cylinder pressures.
  • A new, special engine block design, where the aluminium block is reinforced with the cylinder sleeves.
  • A connecting rod design that lessens TDC dwell time and affords higher mean pressures with no chance of explosion.
  • Specially moulded exhaust manifold and intake plenum trumpets that eliminate back pressure and RPM peak resonance.
  • Ejector pump system that efficiently decreases aerodynamic losses and crankcase pressure.

Koenigsegg engines are compliant with international emission standards; an amazing fact given how much power they produce from their compact dimensions.

The Koenigsegg engine lab is specially built and features rapid prototyping machines, engine and chassis dynamometers and simulation programs. Beside the lab is a 1.7 km track where they can test cars at speeds from 0-320-0 km/h whenever needed. This is apart from the fact that the Knutstorp Racetrack is merely 25 minutes away from the factory by car. Like a smaller version of the Nordschleife, Koenigsegg also uses this facility for advanced car and engine test runs to ascertain if they can work perfectly as a unit. Thus, Koenigsegg is able to improve their engines by making use of facilities that were traditionally only available to more prominent manufacturers.

This is the only engine being produced for any type of vehicle with a cycle fuel consumption of 14.7 litre/100 km or 16MPG, and a power potential CO2 emission at 310 g of CO2. These values are identical to the EU cycle averages. Most importantly, Koenigsegg can credibly boast about the superior performance of their engines in terms of torque generation, responsiveness, harmony, dependability and overall drivability.

The Agera is a clear improvement with greater power than the company’s preceding engines but it still meets the environmental standards set in both the LEV2 and EU5, which are internationally recognised as the strictest. The improved fuel efficiency results in decreased CO2 emissions. This used to be unheard of when talking about a hypercar engine that produces more than 900 hp. Very significantly, driving pleasure and the ability to harness the engine’s abundant power is dependent on its turbo response. A collaboration with Borg Warner gave Koenigsegg the ability to use cutting edge technology turbine materials. The turbines of the Koenigsegg Agera R use Gamma-Ti, a new and special aluminium-titanium intermetallic compound material. The implementation of this material brings down turbine wheel and axel inertia for enhanced engine response. Additionally, Koenigsegg uses a patent pending in-house developed response/back pressure reduction system. Designed by Christian von Koenigsegg, this system gives the Agera engine a big advantage as it is able to produce the most power while remaining compliant to the sternest international emission limits.

The engine’s big, left-side air to air intercooler acts as a great fresh air intake which removes the requirement for water, thus keeping the weight low and preventing problems with heat soaking that could have arisen on long, fast drives.

As is typical with Koenigsegg engine designs, dry sump lubrication allows the engine to be set on the chassis at the lowest possible position while still completely managing the crankcase oil notwithstanding the high g-forces entailed.

The voluminous 80-litre fuel tank makes long trips possible especially given the engine’s high fuel efficiency. Like preceding Koenigsegg engines, the Agera’s fuel tank is situated at the central part of the carbon fibre monocoque chassis for proper constant balance and safety regardless of how much or how little fuel is contained. This proved to be a major reason why the car passed the difficult US high-speed rear impact test from its initial trial.

The Koenigsegg Agera R features four chip modulated bio fuel grade return-less fuel pumps which accurately and instantaneously measure how much petrol is delivered. This makes the pumps more energy efficient as it removes the possibility that there’s more fuel delivered than is actually needed.

The exhaust system is the in-house developed patent pending Inconel/titanium system that guarantees the Agera’s incredible combination of high power with low emissions. It relies on a new essential feature by Christian von Koenigsegg which greatly cuts down back pressure while eliciting a quicker catalytic light off compared to all of the other turbo exhaust systems. Additionally, the exhaust acoustics was made to specifically create the renowned Koenigsegg engine roar.
