Germany - F1 has resisted a push to call off a scheduled engine rule change for 2018.
Earlier, with the end of this season now affected by a spate of confusing grid penalties, some argued hat reducing the per-driver allocation of engines from 4 engines this year to 3 in 2018 was a bad idea.
Red Bull boss Christian Horner said: "I tried to get it changed at an earlier meeting, but there was no support."
But now, at the latest World Motor Sport Council meeting, the original plan to move from 4 to 3 engines in 2018 was ratified.
Not only that, La Gazzetta dello Sport reports that "In 2018, only two MGU-K, batteries and ECUs may be used" per driver without penalty for the entire 21-race calendar.
