Hybrid electric turbochargers how far off are they?

[Jpierro79]

I’m posting this thread as garrret is testing in a Honda civic and an Alfa Romeo 4c their hybrid turbo m. I found it interesting that specifically choosing Honda. Does this mean a future in Hondas for electric hybrid turbos.
For those who don’t know the hybrid electric turbo is a turbo with an electric motor between the the exhaust housing and the compressor housing assisting in just about instant boost at any rpm and after achieving full boost actually becomes a generator producing electricity to control the boost by both charging load and a very different wastegate. Here’s a link

I’d love to hear if any knows about testing in other cars as well. Opinions as well.
Yes we all know it’s too expensive right now but it won’t be in a few years.
But what if we could do it now?
Could you imagine much larger compressor housing generating way less heat making more power with less boost and almost zero lag?

The new Jeep Wrangler uses an interesting concept too. The 2.0 takes a bit to spool so they use a small hybrid motor to assist until the turbo kicks in. It works really well. This is an interesting topic as well.

I've heard of these systems too. Don't they use something similar in some race cars? I'm surprised they haven't already become mainstream.

In order to Mass Produce a design like that, the cost bites into the profit. So, the MSRP would be higher - and that may not be competitive.
Honda (like numerous other manufacturers) are engineering more efficient engines - but they will also keep with roughly the lowest/reliable cost.

Some race cars have them--I haven't looked into it, but I've been told some German cars have them already now.
