There is no belt on prius...
MG1 is motor la, to crank MG2, MG2 i can believe can be start be 12v
Whining is motor sound at MG2 to shaft when on EV
only got timing chain....
the just feel slow bcos of comfort....
the rubber band is just the explanation for people understanding, not the really build
And besides, since u claim Toyota giving fake data, u might as well as them, their test method...
U can claim there and outside people can prove wrong, u can sued for selling bogus items....
If CVT not your cup of tea, shud no buy PC, get something else....
Buy already then complain2, anyway got ppl offer u already ma, sell la....
I also dunno what your problem,
1st say engine, then gearbox, then mg1....since so good, might as well design something better than Toyota, China had claim they built better than Toyota, u can try also....
