The FIA has confirmed Wednesday that works teams and customer teams must have the same specifications of engines in 2016, thus precluding the option of 2015-spec engines being made available for use.
Article 23.5 of the 2016 FIA Sporting Regulations, out Wednesday, reads: Only power units which are identical to the power unit that has been homologated by the FIA in accordance with Appendix 4 of these regulations may be used at an Event during the 2016- 2020 Championship seasons.
That prevents teams from using previous-spec engines, as is the case with Manor Marussia this year (they’re using 2014-spec Ferrari engines). Manor switches to Mercedes power units next year.
While different specifications are outlawed, it doesn’t preclude teams from using different software mapping or fuel products.

Renault seems the only viable option. It’s signed a letter of intent to take over the Lotus team; additionally, Red Bull team principal Christian Horner said during the Russian Grand Prix weekend that the team would be open to a U-turn.
