better MPG with seats up?

I assume that you're having a laugh, right?

 

You're talking about your convertible Prius, right?

 

I'm no physicist, but I don't see how the position of the seats would make any difference in terms of weight or air resistance. Seems like superstition to me.

 

You don't have 500 pounds of cargo in the back when the seats are down do you?

 

Yes, it is quite possible, through what is known as the 'placebo effect'.

 

maybe because the batteries are under the rear seats it affects how cool or warm the batteries are and thus the batteries' performance, especially in the Prius c.

 

[QUOthheoretcallyTE="GeoZoo, post: 2113640, member: 120379"]Generally I always have the rear seats folded flat in my little 2013 C3.

maybe it is just me and I don't have numbers to quote yet, just a gut thing, it seems I better fuel economy when the seats are not folded.flat.

Is it possible that they would make that much of a difference?[/QUOTE]

theoretically you should get better mpgith seats down because the lower CG would enable

theoretically you should get better mpg with seats down because the lower CGenables cornering at higher speeds soless accelreration isneeded after the corner but you'd need a very delicate means of measuring the difference. In truth it makes absolutely no differnce. period.

 

I also get better MPG when I am going down hill. I am not sure about this nor can I explain it but it seems like it does.

Can we PLEASE have a 'hate' button next to the 'like' button? There are threads and comments that just beg for it. Thank you, Prius Chat, for your consideration of this suggestion.

 

The seat trick only works if you hang your tongue out the left side of your mouth. If you hang it out the right side...it uses more.

 

This totally works - drastically alters the aerodynamics of the internal air trajectories while simultaneously adjusting the micro-weight distribution of the internal vehicular positive macro....you know what I don't have time to go into all of the details, take my word - it isn't rocket surgery.

 

My wife is always harassing me about leaving the toilet seat up in the bathroom. I hope she doesn't read this thread.

 

You don't state if you are driving with the windows down? The air flow within the cabin could create a less or more resistance which would impact your MPG's. It could be just coincidence that you are assuming its the position of the back seats.

 

I'd have guessed that with windows open, seats folded flat would have produced better mpg, due to reduced drag against the incoming wind.

 

Depends on whether your listening to the radio or a CD. Government studies have proven a wide range of received radio frequencies are known to cause additional drag and thus avoided religiously by all serious hyper-milers.

Sorry...couldn't resist.

 

You are almost correct, but it actually has to do with if the radio is on or not as the signal creates a drag on the antenna, like an anchor!

 

If your driving style is different when the rear seats are folded flat, then it does in fact make a noticeable difference, although it is an indirect cause, and not a direct cause.
