The two leading teams of this year’s F1 championship Mercedes and Ferrari will use new specifications of their V6 engines for Belgian GP after Ferrari already have tried a new specification in Hungary with their clients Sauber and Haas.
After the positive results of first test of their third and final 2018 F1 engine specification in Hungary, Ferrari has introduced new engines for both Raikkonen and Vettel in Belgium while in the last six races, since launching a new engine specification in Canada, Ferrari uses a different fuel from its customers.
German publication Auto Motor und Sport reports that the new Shell fuel, which Ferrari uses from Canada, has more power, and is not used by customers for unknown reasons, potentially due to the cost.
Mercedes, unlike their late spec 2 intruduction in France, will not be late compared to Ferrari this time and will introduce their third specification on the same race.
That’s why Mercedes’s third engines will have to last longer, but it will be offset by using other specifications on races such as Singapore and on free practice sessions.
Bottas used a new engine after Austria, which has been damaged due to accumulated heat due to long idle time after hydraulic failure, and in Belgium he will take the penalty in order to get a new spec 3 Mercedes F1 engine.
The other two engine manufacturers Renault and Honda will wait before introducing their new engine specifications, which should be in Monza or Singapore.
