Mercedes Benz F3 engine?
The one that is hammering everyone in the British F3 championship, which model of car has it been derived from? Hmmm, always puzzled me as a Mercedes fan!

I think the production engine has direct injection ( GDI / FSI or whatever you want to call it ). Does the F3 engine? If it does then that is its advantage.

The Toyota was always a heavy thing (cast iron block, etc).
GDI is not allowed in F3, it only has conventional injection. In fact, it's the same spec system (even down to the injectors) that everyone else runs. So why are they so fast? (a semi-retorical question) |

With a restricted engine, you are obviously limited on the amount of air you can get into the engine. The idea is to make the best use of this fixed amount of air, i.e. high comp ratio, low friction etc.

Mercedes made one of the best engines of formula 3 history, above all for the skill of the engineers nd technician who worked on it, but also because of the high quantity of money the invest on it.
The biggest differences with all the other engines are the wheight and also the position of the CG, which is a lot lower than the others engines. This is also dued to the presence of a lot of kilos of ballast in the lower part of the engine. All the ausiliary things, like the electric starting engine, are in the lower part of the engine; if you look at it from outside you can see nearly nothing on top. And also, very important, somebody said that the connection to the gearbox make the chassis stiffer than with the other engines. The only problem is what you have to pay to use it for one year... |
