Following the FIA’s formal call for expressions of interest in the supply of an alternative engine for Formula One, the FIA have today outlined the technical requirements under which the alternative engine should be developed.

Whilst no price for engine supply has been defined the FIA have requested this be as low as possible, suggesting price point will be a differentiating factor in any business award decision.

The engine configuration requirement is confirmed to be:

2.5 Litre (or less) turbocharged V6, with a KW output greater than 640, which may be detuned to 530 in qualifying and race levels.

Total weight of the power unit being less than 135kg.

The FIA will impose no limits on Maximum RPM, engine durability or fuel flow.

hybrid power. Hydraulics for the engine must be the same for all teams supplied.

The unit must be compatible with the standard F1 ECU and data logger.

Manufacturers expressing interest in candidacy to become sole supplier of the alternative engine supply will have freedoms around:

Number of turbochargers – 1 or 2

Turbocharges must be able to cope with the maximum boost pressure imposed by the FIA.

Freedom around cranktrain and valvetrain in all areas except crank length.

Freedom is give on the exhaust system, although a variable exhaust system is not permitted.

The technical specification goes to explain the financial boundaries of the submission which includes but is not limited to; all engine sub assembly, all PU pressure charging components (turbo), PU Waste gate and air inlet system, the fuel system and electrical components.

In addition candidate manufacturers must provide support of 5 personnel per team supplied at all race and test events, along with sufficient power unit supplies for up to 20 events and 5000 km of testing.

Candidates have until 17:00 CET November 23rd to register their interest and capability to meet these requirements with the required supporting documentation.
