1. A powertrain system, comprising:

  • an engine;

    a first planetary gear mechanism, the first planetary gear mechanism comprising;

    a first sun gear, a first planet carrier and a first gear ring;

    a first clutch including a first housing and a first engagement plate, the first engagement plate and the engine both being connected to the first carrier, the first housing being connected to the first sun gear;

    first braking means provided for selectively braking the first ring gear;
