an entirely new way of looking at hybrids

Thanks, John. Nice work. I appreciate your help in 'rating' hybrids. I, too, think there is way too much confusion about what a hybrid is, as well as what it does (or doesn't do!). I've tried to explain to people why hybrids are not all the same and most understand the Chevy Silverado truck thing (not a hybrid) vs. the Prius. Not all get the fact that Honda's tech is different than Toyota's. I'll keep trying. My best line so far is: "No one's licensing the Honda technology. Many are licensing Toyota's. That has to mean something".

 

John I have a question. On a very few occasions I have observed, stealth ie electric only according to the MFD at Highway speeds 60-70 mph. Does that mean the Prius gets a point for that? I certainly can not do it on a regular basis, and I have often felt that it occurs on a very slight down hill that I can not see with my eyes but the car can detect a lower requirement for energy use.
Added later : On further thought could you rate out several of the current hybrids and just for yucks add the Chevy (ie 0) I am most interested in how you rate the Prius and the points for the various "electric only" categories as you might expect by my question above. Clearly in the Prius the faster you go the less often you see electric only but it does appear to occur.

 

How about some points for Atkinson or diesel engines. Anything that is better efficiency in a hybrid than regular otto engine should count for more than a hybrid with just a standard efficiency engine. (Presumably diesels would lose what they gain here in the emissions rating.)

Also for the future add points for electric range on flat roads at steady 40 mph, so future hybrids with bigger batteries get more points. (Not even considering the plug in issue.)

 

How about 3 (or more) points for the first hybrid to allow heating to be done electrically? (I.e., the ICE wouldn't have to be on to heat the cabin?)

Unless I'm badly mistaken, the Prius (and I suspect everyone) hasn't got this feature. (Not that I'm complaining -- I'm very impressed that full electrical cooling is done.)

 

Surely he meant electric heat only as needed. One would still make full use of engine heat whenever it is available.

Yes -- apologies for not being clear about that.

Or specifically, heating the cabin without having to run the ICE specifically for that purpose. (If there's engine heat there, use it -- but don't run the engine for the sole reason of heating the car.)

 

The electric heat is pretty anemic to the point of useless if you ask me, and I am in a mild climate!
