As the Agera R is a flexfuel car, it can also be run on normal petrol. As 95 octane fuel has less octane than E85, the power is reduced to 960hp with 1100nm 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 implement 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.
