In Austria, Ferrari tested a new, second specification of its internal combustion engine, but not in theur SF70H, but in Haas VF-17, which shares many other components with their Italian cousin.
Romain Grosjean and Kevin Magnussen in Austria received new engines, turbo chargers, MGU-H and MGU-K. These were the third internal combustion engines, the third MGU-H and MGU-K units, but also the fourth turbo chargers that were problematic for Sebastian Vettel who had been on the fourth turbo charger for a long time.
At a time when the FIA announced that there was a change in the engine in Haas, it was not known that it was second Ferrari engine specification, but AMuS reports that the Italians first wanted to test a new specification in the car of their clients from Haas.
The Haas VF-17 and the Ferrari SF70H share the same power unit, transmission, suspension, hydraulics, electronics and all other components from the list of permitted shared parts, so Ferrari decided to use this opportunity to try out a new engine specification before they use it in the next race on Silverstone.
Haas was very fast in Austria, thanks in particular to the new Ferrari engine, and Grosjean finished sixth in qualifying and seventh in the race.
The new engine in the qualifying mode brings a double-digit increase in horsepower (10-15 HP), according to AMuS claims, and judging by a successful test in Austria, a new engine in England should also get Raikkonen and Vettel who are currently using their number two engines.
It is not yet known whether a new turbocharger model is required for the new engine, as Vettel would have a 10-seat penalty at the start of the race in that case.
Also, some sources suggest that Ferrari will run even newer spec of their engine in Silverstone, despite Haas also getting a version that is new to them.
