The Agera R, based on the highly competitive Agera, follows in the footsteps
of the CCXR as it also runs on E85 biofuel.
Among the many differences to the standard Agera, the Agera R has an upgraded fuel and engine management system with enough flow capacity to generate 1140 hp and 885 lb-ft (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 2000 hp petrol engine, which means that the Agera R's return-less fuel system has the highest capacity of any car presently in production.
As the Agera R is a flexfuel car, it can also be run on normal petrol. As 95 octane fuel has less octane than ethanol E85, the power is reduced to 960 hp with 811 lb-ft (1100 Nm) of torque due to the boost pressure and ignition timing being altered to match the fuel characteristics.
In order to give the Agera R maximum flexibility when it comes to power delivery, Koenigsegg has implemented the latest technology when it comes to turbo materials and design. This reduces the inertia of the turbine wheel and axle and therefore gives improved response.
