FIA opens tender for Formula 2 engine supply with hybrid power on the cards

LinkedIn +

The FIA opened the tender process for supply of spec engines to the Formula 2 championship from 2024-26 at the end of July, with an option to extend any agreement to 2029. The current engine supply deal with Mecachrome for its V634, a turbocharged, 3.4-liter V6, concludes at the end of 2023.

The FIA specification calls for an engine producing 630PS at an inlet pressure (pre-compressor) of 1013mb, though the tender does not specify a requirement for turbocharging. However, if forced induction is used, the power requirement must be met at a plenum air temperature of 42°C (25°C for naturally aspirated).

The total weight, including clutch and exhaust but excluding parts such as coolers and ECU, is specified as “less that 150kg”. Finally, the tender demands a running life of over 10,000km, with a maximum of +/-1.25% deviation from the declared power across the top 2,000rpm of its operating range, which must be maintained for the complete engine life.

Notably, there is also mention of a potential need for hybrid compatibility, either through the inclusion of a power take-off for an electric motor or integration of a mild-hybrid generator.

The selection process will follow three stages, starting with the tender and identification of potential suppliers who will be asked to submit their bids. All tenders that meet the FIA criteria will be passed to the series promoter for commercial negotiations and selection of a favoured bidder. The FIA will then appoint that bidder as the sole engine supplier.

The deadline for tender submissions is September 2.
