When was the last big engine regulation change?

Thanks ahead guys.

'big'?

 

1989 they went from 1.5 Turbo (and 3.5) to just 3.5

1995 they went from 3.5 to 3.0

2006 they went from 3.0 to 2.4

iirc up to 1994 there was a mixture of V8s, V10s and V12s, but in 1995 V10s were mandated and in 2006 V8s were mandated.

 

More significant than any of those changes, in my opinion, was the reliability revolution - the development freeze (i.e. de facto performance equalisation), rev limit and limits on engine changes, making engines last multiple races. It will be interesting to see how the resumption of competition alongside the retention of the limit on engines per season will work. In my view the imperative to chase performance will make the reliability element much more difficult to achieve than it has been in the past. You can't rule out that a major title contender will run out of engines and have to take grid penalties towards the end of the season.
