Gen 5 Prius (possible in 2021) will we possibly see 60mpg?

    I think TOYOTA don't do too bad mostly - some glaring things though - like no HillHolder in reverse.

    But Android/Apple Auto weren't released till just before PRIUS Gen 4 was signed off on in 2015 - almost no cars had it at that stage.

    That said - TOYOTA seem to be in a "rut" - with their attitude to updates during model cycles. If it's not on the first Gen 4, good chance it won't arrive till Gen 5. Other manufacturers add stuff on an ongoing basis.

    Maybe an air-aluminum battery?

    That would certainly make the battery less attractive to thieves. (y)

    Air-aluminium battery, that would be nice a non-rechargeable battery in a hybrid or EV... Not.

    Yes, my thoughts too.

    I think they're hoping to develop them as rechargeables eventually. But not "just" Al - but Sn as well last I read, along with traces of Co I think. The aluminium was self destructing in pure Al form.

    Last I read it sounded like 2021 would be impossible.

    From what I know, the reciprocating ICE has almost reached its theoretical efficiency limits in the thermodynamics-, combustion- and mechanical departments. Therefore if you insist on converting energy from chemical into thermal into mechanical, you will have to bang your head on the law of diminishing returns.

    The overall efficiency of a hybrid should be improved by increasing the battery capacity to more fully capture the energy of deceleration and driving downhill, and to allow the ICE to stay within its favorite RPM range (or off) for longer. Still better, how about giving all Gen 5's a 240V plug and enough electric range to run about town and/or to do the proverbial "average" US commute of 40-50 mi/day. Even betterer, make the traction battery modular so folks can order the capacity they need for their driving patterns, as a rough equivalent of the engine choice in pure ICE vehicles.

    For Gen 6 or 5.5, in about 5 years, I'd like to look at a Prius Prime with 120 mi BEV range and a LPG SOFC range extender, if I may be so bold.
