2014-2020 Formula One 1.6l V6 turbo engine formula

I just watched a video on permanent magnet vs. induction electric motors and made me think about what kind are used in F1.. does anyone here know?

From what I saw in the video, I guess having both is best case scenario, but I doubt that's the case, so I'm guessing they are using permanent magnet because they can deliver more power at higher speeds.

According to CAR MAGAZINE - (CARMAGAZINE.CO.UK OF 2020) MGU is a permanent magnet brushless AC electric motor.

to not impede gearshifts the MGU-K needs high acceleration/deceleration ability 10000-11500 crank rpm in c.5 millisec
the induction machine can never be responsive enough for this

interestingly the latest plan for 2026 is to continue having 8 speeds (6 was predicted)
the rpm drop being 40% more with 6 speeds it's likely there's a shift response issue (with 6 speed & 2026-size MGU-K)
