HYBRID P1

LMP1

"LE MANS" PROTOTYPE 1 category includes:
  • "LE MANS" PROTOTYPE 1 Hybrid: with Energy Recovery System (ERS).
  • "LE MANS" PROTOTYPE 1 : with no Energy Recovery System (ERS) reserved for privateers.

The LMP1 Private Teams category is reserved exclusively for independent private teams. A team that is independent of a manufacturer means a team that does not benefit from any support from a manufacturer other than for the single supply of engines, services relating to these engines or commercial support. Any support from a manufacturer relating to the chassis or to chassis systems is prohibited. It is understood that traction control is considered as a chassis system.

Engines

Engine is free except following restrictions:

  • Only Petrol or Diesel 4 stroke engines with reciprocating pistons are permitted.
  • Engine cubic capacity is free for "LM" P1-Hybrid cars
  • Engine cubic capacity must not exceed 5500 cm3 for "LM" P1 cars.

Number panels

Pantone red 485, with white numbers

Driver Categories

Bronze drivers are not permitted

Minimum weight

878 kg for LMP1-Hybrid
833 kg for LMP1

Dimensions:

  • Wheelbase: Free but it must be identical to that registered in the Homologation Form
  • Overall length: 4650 mm maximum
  • The front overhang is limited to 1000 mm
  • The rear overhang is limited to 750 mm
  • Overall width: 1900 mm maximum and 1800mm minimum
  • Height: No part of the bodywork is permitted to be more than 1050 mm above the reference surface

Fuel Flow Metering:

A homologated "Fuel Flow Meters" sensor must be fitted which directly measures the fuel flow through the fuel feed line to the engine. By measuring the instantaneous
flow the total fuel consumption can be calculated. The LMP1 will be constrained on both: fuel energy per lap and maximum instantaneous fuel flow.

Fuel Tank Capacity:

Petrol 62.3 litres with ERS, 75 litres with no ERS
Diesel 50.1 litres with ERS

Fuel Energy per Lap:

The fuel energy per lap is the total amount of fuel energy contained in the fuel mass allocated for one lap.

Technology Factor:

The Fuel Technology Factor is a function of the ratio of Diesel over Petrol engine efficiencies.
The K Technology Factor is a function of Diesel and Gasoline powertrain weight and ERS options.
Those factors are used to calculate the relation between diesel and gasoline allocated energy and maximum instantaneous flow.

Maximum instantaneous fluel flow:

The fuel flow is limited instantaneously and therefore limits the maximumengine power.

"LE MANS" PROTOTYPE 2 ("LM" P2) is a racing car with no production minimum required.
It is a closed car, destined only to teams independent of manufacturers and/or engine suppliers.

The selling price of the complete closed cars must not exceed €463.500.
