LMP1 Privateer teams will get an extra boost heading into next weekend’s Six Hours of Circuit of The Americas, with the non-hybrid-powered prototypes set to benefit from a performance increase.

The FIA Endurance Committee has confirmed fuel capacity, petrol flow and petrol energy adjustments for the Rebellion R-One and ByKolles CLM P1/01 prototypes, aimed to bring the cars closer in performance to the factory LMP1 hybrids.

Among the changes include an increase in maximum petrol flow (101.4 to 106.5 kg/h), a boost in petrol energy (70.6 to 91.8 MJ/lap) as well as a 7.6-liter increase in fuel capacity (67.4 to 75 liters), compared to the initial numbers published for the circuit in late July.

The changes come in the wake of last month’s Six Hours of Nürburgring, which saw the quickest non-hybrid still more than 5 seconds off the pace from the pace-setting hybrid-powered Porsche 919 Hybrids and Audi R18 e-tron quattros.

The Equivalence of Technology adjustments have currently been defined for COTA only, with further analysis expected before confirming changes for the remainder of the season.
