Assume only 1/100th of 800HP and you need 8HP, which is about 'half' of the typical 15HP that todays cars typically need for highway (60mph) speeds.

Consuming 'half' again more power is going the wrong direction when chasing fuel economy.
The E-Charger would only run for the ten seconds or so that you need to accelerate. So while it would be using a substantial amount of power during that time, it would be more than offset by using a smaller engine.

Unlike a conventional supercharger it wouldn't be spinning and using power the whole time. Similar to the way a hybrid car only uses it's ICE when needed.

We've seen quite a few e-Charger concepts from major OEM's, the only reason they haven't reached production is essentially turbos do the same job cheaper.

I'd love to retro fit an e-Charger to my Proton. It's 0-60 time of 14+ seconds is a bit on the slow side, and it needs a lot of revs to get there. An e-Charger would add a lovely bit of sub 2000rpm shove to my drive while being cheaper and more DIY than an engine swap or turbo conversion.
