WRC Testing

Correct me if I'm wrong but I thought that the electric turbos used in the F1 or Le Mans are actually normal exhaust-driven turbos where only the initial rotation is made by the electric motor to remove the lag, i.e. it's only a kind of electric ALS. Do I undertsand it right?

Yeah you are. It is a motor generation unit (called MGU) that can be used both for PTO and PTI). It is used a bit complexely like spooling up turbo and it is rumored that it is also used in overtake situations to boost the turbo further... Not sure whether this is true or not though

Also the gearbox is coupled to such a unit and it has the same properties only bigger size

TBH I was not familiar with technology around e-turbos. After looking it up it seems you are indeed right. The electric motor turns the turbo when you fo from off to on throttle. It would be interesting to know the power consumption of such an electric motor, I dont believe they can be driven from normal battery. They seem to store energy in a super-capacitor when you go off throttle, i.e. doing partly the work of a wastegate. For WRC max voltage allowed is 16v.

On another note, only a list of FIA approved turbos are allowed, all from Garrett.

See your PM

Thanks, it's clear now that they can't use them.

Should we be reading anything into the fact that Lappi is testing the EVEN/Printsport Fabia R5 today? Maybe just an additional bit of seat time that wasn't scheduled with the factory?
