D8.23 Fuel E Scoring Formula

D8.23.1 CO2 conversion factor

The mass of CO2 released to the atmosphere will be assessed by using the conversion factors below

from quantity of fuel used to CO2 released. The factors are intended to represent the average supply

of the appropriate commodity and the organizers will not take account of where the actual fuel used came from.

Unleaded petrol / gasoline – 2.31 kg of CO2 per litre Electric – 0.65 kg of CO2 per kWh E85 – 1.65 kg of CO2 per litre

Note: the Electric energy value includes the anticipated charging losses if the pack is charged over 2 hours.

D8.23.2 EV credit for regeneration.

For EVs that use regenerative braking, any braking energy that is recovered will be deducted from the amount of energy used after applying a factor of 90%

Note: the factor of 90% reflects the organizers understanding of a typical round trip efficiency of a battery.

D8.23.3 Fuel efficiency will be scored using the following formulas:

Where:

Vmin is the smallest volume of fuel used by any competitor, whose Endurance time Tyour <

1.45 x Tmin

Vyour is the volume of fuel used by the team being scored.

Tmin will be the lowest corrected Endurance time of the fastest team of the event, whose fuel volume does not exceed 26 liter/100km.

Tyour will be the combined corrected times of the drivers in your heat.

Lapyours will be the number of laps driven by the team being scored.

Laptotal will be the number of laps for the full Endurance distance.

D8.23.4 Vehicles using a fuel volume which exceeds Vmax by 33% will score negative one hundred (-100)

points.

D8.23.5 Vehicles whose corrected time exceeds 1.45 times the corrected time of the fastest team, will receive zero (0) points for fuel efficiency.

D8.23.6 For shortened courses, Vmin will be the low value per heat.

D8.23.7 Fuel efficiency scores can range from zero points (0) to positive one hundred (100) points. D8.23.8 Vehicles which cross the start line following driver change are eligible for Fuel Efficiency points.

Other vehicles will receive a score of zero points (0) for Fuel Efficiency.

D8.23.9 The minimum combined score for the endurance and fuel efficiency event will be determined according to LapsComp as defined in D8.19.2
