Exhaust Heat Recovery optional?

HTMLSpinnr · 04-30-2009, 10:34 AM

I've spotted in more than one manual, coolant specs with and without "optional" exhaust heat recovery. Is this an optional feature not included in some models?

According to the documentation I have from the press event, it's a standard feature of the 2ZR-FXE, not an option.

That would be a criminal thing to remove from Prius I, but I bet it would save some money...

Right - the fact that they go as far as to specify coolant capacities with and without the system suggests that SOMEWHERE it is an "option".

Maybe they will not include it in the Prius I ($21,000).

Could be a possibility, but there's no way I'd consider a 2010 Prius without one. On short trips, your fuel economy is going to suck! But who knows, maybe it just brings down the short trip fuel economy to Gen-II levels in which case, a lot of people might consider it to save a thousand bucks.

Can you show us the documentation you are referring to, Rick?
Seems strange to offer such a stripped version anywhere.
