Which Ferrari F1 engine did she choose?

After the failure of the 2020 engine, the Scuderia made progress with block 065, especially in terms of the hybrid system. A further leap forward is expected this year, perhaps with a change in architecture.

What do we know about the engine that will power the Ferrari currently known under the code name “674”? It will include, with some adaptations, the ERS introduced at the Russian Grand Prix last season and which has doubled the voltage of the battery:

“Next year’s engine is very different from the previous one, except for the hybrid system, explains Mattia Binotto. We introduced a new version of the ERS during last season, anticipating what the rules were going to be in 2022. The system is therefore very similar to what we used at the end of the championship.

“The rest, however, is radically different, especially the combustion engine. The teams will have to use gasoline containing 10% ethanol, which will cause all engine manufacturers to lose around twenty horsepower – a sign that combustion has been largely affected. As a result, there was no shortage of development opportunities on the thermal V6, and we have modified it in depth.”

What is this “radical” difference to use the words of the boss of the Scuderia? It has been known for some time that the Prancing Horse is working on two versions of its powertrain, developed by Wolf Zimmermann (poached in 2019 from the Austrian firm AVL).

The first, quite radical, adopts “separate architecture” imagined by Mercedes in 2014, which splits the compressor, placed at the front of the engine, from the turbine, installed at the rear. On the Italian V6, however, the compressor would be located further back, inside the air box itself. This design offers minimal bulk and avoids giving the oil tank a convoluted shape, which complicates its operation, but involves reviewing the intercooler.

Is this option mentioned in various media realistic? Not sure. It has already been explained elsewhere, this solution of miniaturizing the compressor to favor the aerodynamic package is at the root of the problems encountered by Honda on its “zero size” engine. Moreover, the failure of the 2014 V6, miniaturized to leave more room for maneuver to the aerodynamicists, left traces in Maranello…

In any case, the first version would share with the second a new combustion chamber, which would allow extremely short ignition times, in order to compensate for the regulatory fuel pressure limitation set at 500 bars. On the other hand, it would retain a classical architecture. This version, more classic in its architecture, would have been finally retained by Binotto, because it would have been more reliable on the bench.

To be sure, however, we will have to wait to see the photographs of the garages that will be taken during the first tests (from February 23 to 25 in Barcelona)? An exercise in which F1i is experienced, which publishes exclusive technical images every week.

What is certain is that the robustness of the powertrain will be an important criterion insofar as the engines will be homologated on 1er March for a period of four years (until the end of 2025, therefore).

It is therefore a question of not being mistaken. the V6 2021 marked a first step forward, block 066 must put the Cavallino back into a gallop.
