Enhancements included: visible carbon on the front bonnet and bumper, new front side winglets, an all-new Aero exhaust, increased engine power with a raised RPM limit.

The Agera R also saw the debut of Koenigsegg’s own ceramic piston brake system.

In 2011, the Agera R set a new world record for driving 0-300-0 kph. The time of 21.19 seconds was only eclipsed in 2015 by the Koenigsegg One:1.

Koenigsegg was the first hypercar manufacturer to take steps toward green technology with the biofuel CCXR in 2007. The Agera R follows in its footsteps with an upgraded fuel and engine management system, allowing it to run between 95 Octane and E100 biofuel, or any mix in between. The engine management system senses the fuel mixture and adjusts the engine’s operation accordingly.

The Agera R’s fuel system has enough flow capacity to generate 1140 hp and 1200 Nm of torque on E85 and E100 biofuel. As there is less energy content per given volume in these biofuels compared to normal petrol, the fuel system has to manage a flow that is similar to a 2000hp petrol engine, which means that the Agera R’s return-less fuel system had the highest capacity of any car in production at the time.

As 95 octane fuel has less octane than ethanol E85, the power is reduced to 960 hp with 1100 Nm of torque due to the boost pressure and ignition timing being altered to match the fuel characteristics.

The Agera R's power delivery was boosted thanks to a redesigned turbocharger using a new configuration and new materials. This reduced intertia in the turbine wheel and axle, improving response and top-line performance.
