    Seem like turbos hooked to gassers do best when they're doing higher RPMs. Doesn't that defeat the purpose of a hybrid system that does it's best at low rpm?

    I'm not sure I buy the question's premise that a hybrid system does "best at low rpm".

    Seems to me the key design win with a hybrid is the ability for the power management control ECU to know the engine's optimal rpm for whatever amount of power is demanded, and to send the engine straight to that rpm and match it to the wheels.

    But I'm thinking of the Prius-style CVT arrangement. If this transmission works some other way, I could be off base.

    The theory is that the hybrid motor provides the low end torque as the turbo spools up - getting rid of the turbo lag, flat spots in the power band.
    It's a regular transmission, NOT like a Prius transaxle. The electric motor replaces the traditional transmission torque converter. It's suppose to have more low end 'grunt' while rock crawling.

    Haven't test drove one, so I don't really know. .

    They use a ten speed automatic behind one hybrid motor.

    The Tundra takes advantage of its electric power and torque at the low end like other hybrids. Overall it's pretty fast with a zero to 60 around 5.6 seconds. MPG is minimally improved by 2 mpg so power is the selling point.

    Overall I think its too complex with twin turbos, dual injection and hybrid components.

    The marketing guy claimed a small hybrid truck will be available in a year of two.

    Not how I would approach the problem but 'less bad.'
