Problem with it is that every year they make this claim which at least ‘till last season turns out to be only a continuation with the base of the engine of the season before. So instead of a revolutionary improvement it always turned out to be a rather small evolution of the design of the engine.Remi Taffin, the lead engineer who is in charge of the engine, said last year that they were working on a brand new engine for 2019 (and Alain Prost was really enthousiast about that).
Here we are.
And yes, I really hope they finally do make a big step forward and they finally put the money where their mouth is! For a change not only words but also results.
