When?
E.Torque is system which can be fitted on any engine. It's a belt driven 48V mild hybrid system. It's a P0 system or how FCA calls it a P1F ('F' as front) system.
I'm expecting more advanced P2 48V mild hybrid in the future. FCA has it in the plans. Which engines or vehicles will receive it?
I don't believe that Alfa will use it. Maybe Maserati.
Alfa has their own V6 90° which is based on Ferrari V8. It has 510 HP. They are working on a 600+ HP version of that engine with e-turbo. Target is 650 HP.
For lesser power level the have 2.0 GME 4 in the plans. With e-turbo capable for at least 350 HP.
At least Alfa's electrification plan is no secret:

On the left is a P1F belt driven system. It could be a Magneti Marelli e.Torque system or something very similar from a different supplier.
In the middle is a e-turbo. Usually it's related with a P2 48V mild hybrid technology but not necessary.
On the right is a PHEV. Different system compared to a one on Pacifica. Actually FCA has at least two PHEV systems in the development which are not related to Pacifica's system. AFAIK one system is for a FWD based cars with a rear e-axle. It should debut on Renegade.
The other one is a system for RWD based cars. Most likely it will use ZF 8HP transmission.
