    So does the Prius, starting with gen 3. The one in gen 4 gets posted about here when it springs leaks. (For whatever reason, the gen 3 one didn't seem to do that as much.)

    Is it an actual air (exhaust gas) to water(coolant) located in the actual exhaust system or an EGR type system? The Niro actually uses both.

    I am not familiar with the newer generation Prius.

    If it weren't, I wouldn't have mentioned it.

    After some looking into it, BMW is actually doing it with their turbosteamer.

    "The turbosteamer device is affixed to the exhaust and cooling system. It salvages the heat wasted in the exhaust and radiator (as much as 80% of heat energy) and uses a steam piston or turbine to relay that power to the crankshaft. The steam circuit produces 14 hp (10 kW) and 15 ft⋅lbf (20 N⋅m) of torque at peak (for a 1.8 straight-4 engine), yielding an estimated 15% gain in fuel efficiency. Unlike gasoline-electric hybrids, these gains increase at higher, steadier speeds."

    15% in fuel efficiency might not be a lot, but its something I guess. If prius had this device in our cars, i could see it maybe getting to 70mpg average instead. Would be interesting to try and see if its possible to mod one in.

    It would be interesting to see if Toyota could democratize that tech, but I still maintain that even a real-world measurable gain in fuel economy for an equal gain in price would only be attractive for people that suck at math.
