What is LMP3?

back

From ACO Press Release

The philosophy behind this car is to have the fewest restrictions possible whether from a budgetary, technical, driving or running point of view.


The technical regulations of the car will be frozen for three years minimum and this set of regulations
will be in force for at least six years.

Around 2 seconds quicker per lap than that of an LM GTE on a normal circuit.

The safety standards imposed will comply with those required by the FIA (Fédération Internationale
de l’Automobile).


Chassis and bodywork


These elements will very close to those used on current LM Ps:


- Closed carbon chassis with a metal rollbar


- Slightly smaller dimensions than the LM Ps


- An obligatory crash test
- Identical visibility guaranteed
- Shark’s fin
- Openings on the top of the wheel arches
- Weight between 870 and 900 kg (to be confirmed)
- Obligatory power steering
- Plank under the chassis


Any constructor can build this chassis.


The following companies are already working on the creation of LM P3s or have shown an interest:
Onroak Automotive, SORA/Sébastien Loeb Racing, Tatuus, Riley-Scott, Norma and Juno.

Engine

The LM P3 powerplant is a NISMO-tuned Nissan VK50VE 5-litre normally-aspirated V8 engine.


There will be a single engine for all cars : a V8 putting out around 420HP.


The engine management system will come from Magneti Marelli.

Xtrac will provide the gearbox, a semi-automatic transmission with 6 speeds + reverse and steering wheel-mounted paddles. A minimum of 7000 km will be demanded between two revisions.


This package will be sold by Oreca, which will provide a back-up service to help the teams at all the
circuits in the different championships. As exclusive supplier of these packages ORECA is not allowed
to design or sell LM P3 chassis.


A single engine will be allowed per car per season and each one must be guaranteed for 10 000 km
without maintenance.


Common parts


A certain number of other common parts will be imposed on the different constructors and teams to
cap manufacturing and running costs. These may include wheels, brakes, fuel tanks, safety elements,
etc.


Tyres


The size of the tyres will be similar to those used in the Porsche Cup. Each championship can call on
the manufacturer of its choice and the entrants in the series will have to use these tyres.


Costs


The sales price of these cars by the constructors to the teams cannot exceed 195 000 euros (chassis:
around 135 000 euros, engine: around 60 000 euros).


The running costs of a car over an ELMS season should be between 350 and 400 000 euros. Thus, for
a car with three drivers the budget per driver for a full season will be in the region of 120 000 euros.

In order to cap costs of personnel at the circuits, the ELMS will take charge of refuelling the cars in
the race
(but not tyre changes).


In the ELMS four people maximum will be required to look after an LM P3 in the race during a
meeting
as opposed to eight at the moment in LM P2. Six to eight people will be enough for a
weekend in LM P3 compared to around twenty for an LM P2.


The selection criteria for the drivers will be defined later. However, the LM P3s, access-level
prototypes for endurance, are aimed in priority at young drivers and gentlemen drivers.
