At least I think it's interesting. The power output along with that mileage is incredible. Now, I'm curious to how the engineers are going to design the electrical system to support the turbochargers.
It seems like a very logical design engineering wise; the amount of rotational energy (torque) to spool up the turbo initially would be negligible, about the time you need a good amount of energy to continue to push the air into the cylinders you would then have the exhaust gasses picking up the work when there is more atmospheric resistance.
More power, gobs of torque and great mileage- what's not to like? It doesn't take a leap of imagination though to predict the price of admission in an Audi, more than I'm willing to or able to in a car. Let's hope for downward engineering to the masses!
Considering that the chargers themselves are no longer powered by waste exhaust gasses, is it technically still a turbocharger?
Maybe electrocharger?
Unless I'm reading it or looking at it wrong I'm pretty sure that this turbo design still uses exhaust gasses. The electric part of the system is to spool up the turbo vanes quicker to eliminate turbo lag and to give an extra boost of available pressure at times where a traditional exhaust gas driven turbo would be lacking; there is a bypass valve and plumbing that would indicate a two part boost approach.
An electrically driven turbo charger isn't a turbocharger, it is a supercharger. A turbocharger is driven by exhaust gases and once you use a motor to drive the turbine, it becomes a supercharger.
An electric turbocharger can't by definition, exist.

That's what I gathered. It's a electric "pre-spool," an evolution on the old super-turbocharger hybrids that invariably all were horrible but using electricity rather than belt drive. Very interesting.
Correct. So it is a new twist on an old idea.
I don't see why a 'trickle down' effect for other cars wouldn't be on order for the system. It doesn't look like a leap in technology. Just a good reworking that can be put into production.

The way I read it is that it's a sequential setup where the smaller turbo, if you could call it that, is electrically powered to provide low-end torque while the second, conventional turbocharger takes care of the high-end torque/power. Seems similar in principle to the twin-charger setup VW already uses in some of its European models but with the low-end supercharger being electrically driven instead of belt-driven. I assume the electric-driven compressor is centrifugal; I don't know what the supercharger type is in the current twin-charger unit.
