Default 48 IMA vs. 48 HSD 9/29/05



Anyone know how long it's been tied? This is interesting to me.

For a long time.

Note two things, though:

It is *manual* IMA vs auto Prius.

The histogram for the Prius has approached a very close approximation of normality, but neither of the Honda Civic IMA cars have. You can make your best guess what a normal distriubution will look like, or wait for a larger cohort.

considering how advanced the HSD system is vs the IMA a 3mpg difference isn't all that great. Especialy when we are talking about upper 40s for both. Of course we are also talking about gen I IMA vs gen II HSD (or was the first gen prius even considered HSD?).

Overall a close race. It will be nice to see how the race gets tighter as each company advances their technlology.

True for MT, but the CVT is right on target for a normal distribution. Unfortunately, a larger cohort for MT will never be available, as they're being discontinued beginning officially next week. This is probably close to as large as we'll see for them.

I like the Honda IMA, so take the following comment as a nitpick:

The '05 Civic has a built-in advantage of being lighter and smaller. In the great IMA vs HSD debate, that should be taken into account.

And now, up on to my podium, to say that in terms of value, current hybrids fail in comparison to the simple act of downsizing.

You could not see the tie until version 2 of the database because version 1 mixed the results for the CVTand the MT. When version 2 came out the data was split and the MT got its own spot.

I really hate that the manual version of the hybrid Civic is getting the boot, what am I gonn abuy in 6 years when I have my car paid off? I won't go back to an auto! Hopefully by then they will have seen the light and given me a better model of my car.

I normaly cant stand automatics, but the CVT I have is sooo nice. If they prove to be reliable I will have no problem with a CVT in my next car as well.

Well, Toyota's pretty insistent that the HSD system would outperform a maual Prius, so I think it's actually a fair comparison.

Maybe if Toyota gets attuned to hypermiling techniques they'll change their mind and make a manual six-speed Prius. But until that day, I see nothing wrong with comparing the manual HCH to the Prius II.
