These use electric motors to spool up the turbo at idle and low speeds,
so it's putting out boost pressure right from the start. The objective
is the same, to eliminate turbo lag.

It'll be interesting to see how it plays out, particularly with keeping
an electric motor happy when it's being run up close to the exhaust
system.

Next will be electro-turbo-compound engines, where, at high speed, the
turbine motors are used as generators. Given enough power handling
capability in the turbo motor you could use it instead of a waste gate to
regulate boost; this would work especially well in a hybrid.

Hybrid electro-turbo-compound variable timing multi-BS whatnot.
