GM disputed Prius Aerodynamics - any follow up?

Seems reasonable to include in the wikipedia article that GM modified the stock Prius for its internal testing; that the GM protocol is different than the internal Toyota protocol and is not expected to give similar results; and lastly, that the Toyota protocol is likely to model real-world closer than the GM protocol, since wheels spin in the real world.

My more general question is, in testing where everything is the same except wheel spin, how do the results change ?

 

I would have used the 15s, but mounted them sideways.

Because Volt is on the cusp of a breakout year, 45k sales in US is it?

Consumer Reports speaks highly of it and they recommend it for this year. IRC, CR said they got 32 MPG in Volt after EV party over. They also claim 44 overall in Prius. Sounds like they include lots of trips to the corner store

 

I've said it before, I'll say it again.

Figures lie, liars figure.

 

The neo-fascists who run GM are full of crap, and have been for decades.

 

I don't know about neo-fascists, but I agree that GM's "fact" reporting is about on par with Faux News.

 

Volt can't have 15" wheels because it weights more than a SUV.

 

Accuse me of extreme disinterest.

But GM disputes Prius aerodynamics? I don't care.

I suppose you can spend a lot of time debating the wind tunnel protocal of GM vs. the wind tunnel protocal of Toyota.

But why should anyone care? Let GM dispute it. Is disputing The Prius aerodynamics going to change reality? The reality of Toyota having the highest gas mileage hybrid vehicle that is mass produced and actually available to the masses? Is it going to change the fact that while Toyota expands it's range of hybrid products GM continues to half heartedly advance The Volt? Which is a niche product, well out of the range of obtainment for most people?

Disputing the aerodynamics of Prius? Just sounds like sour grapes. How about GM stop wasting time disputing the aerodynamics of Prius and start building products that can legitimately compete with Prius? I mean, if you are going to waste time putting your competitors vehicle in YOUR wind tunnel, how about you learn something from that same product?

What do I care what numbers GM produced? Honestly, I barely care what wind tunnel numbers Toyota produced. The Prius....is The Prius. I don't think most consumers are buying the vehicle to put it in a wind tunnel, so the numbers are nice but from a practical point of view?

I've got a lot of other things to worry about than GM and Toyota disputing the aerodynamic numbers of Prius.

 

o this is so funny
while doing the wind tunnel test : Toyota is moving GM is standin still.... yes. ;-) where did i hear that before about GM standing still

 

^^ Hummer, not Yukon

 

Apples and Oranges.

I see a big difference.

If GM were to contend that a standard ICE Yukon pollutes less than a Prius? That would be a flat out misrepresentation and lie. That I think anyone would hotly contest.

A dispute over a fraction of results difference in wind tunnel testing?

My guess is GM was able to produce the results they are proclaiming...through whatever tweaking of the process.

My guess is Toyota's results are just as valid, using their process.

It's in Toyota's best interest to advertise the aerodynamics of Prius as being as efficient as possible.

GM probably doesn't mind some headlines popping up questioning Toyota.

But I'm sorry. In this case I really don't care.

If Toyota wanted to get even, they could always wind tunnel test the Volt...but then again? Why should Toyota care about The Volt? In a way? It's a backhanded show of respect that GM is even wind tunnel testing the Prius and bothering to quibble over such ridiculous minutia...IMO just to create a headline.

I sincerely doubt any consumers or potential Prius owners are going " Ya know, I wanted a 0.25 cd Prius, but GM says The Prius is really only 0.31 cd...so I think I'm going to pass and buy a Chevy Cruze instead..."

My advice...ignore it.

 

And right up there with MSNBC.

 

For some reason GM does not trumpet the fact that the Cruze/Volt is a recycled Daewoo design.

So here are the two contenders:
Corporate Toyota, reporting on a car they designed from the road up for aerodynamics
Corporate GM, reporting on a Daewoo.

Is there a question here ? LOL

GM IMO puts out their garbage to keep the cars in the public eye. So far they have managed to BS around 7k Volt buyers with their marketing efforts.

 

Not even close. NBC is poor quality reporting, Faux News is a propaganda outlet.

 

Puhlease, both are spouting propaganda. In any case, you confuse the news reporting with the commentary, as is typical of those who can only see lies and propaganda when it stands in direct contrast with their ideology.

 

And real hummers were never made by GM. GM's Hummers were just a brand name.

Don't know about that. I think GM's given us some pretty good hummers over the years.
[Sorry. My bad judgement knows no boundaries.]
