Can you elaborate on where these figures come from, and what exactly they include please?

The point being that it's not mpg that matters when considering the impact of your car - a Prius battery is terrible for the environment and the parts for it are made all over the World AND has to be replaced regularly.

But a Hummer is made all in one country, so despite being very thirsty, it makes much less impact than a Prius!

Try telling that to a Tree hugger though.

Brainwashed by Governments wanting to raise more money by taxing us all, and claiming the Tax will save Planet earth. From what I don't know? Alien invasion I think

A Hummer has also a lot longer expected usable life as well !
All figures can be distorted one way or another! If looking at it this way Land Rover / Range Rover do well as often see 15 / 20 years old Range Rover / Land Rover happily pottering about !
Nice statistic to shove in the tree huggers pipes and smoke it ! My old 3.9 V8 Range Rover is actually good for the environment !!

Financial energy costs don't show the environmental impact. What about the CO2 per mile?

Andy - I'm trying to find the source (mayeb GM?!) but no luck so far.

It's basically the entire lifecycle cost of a car from extraction of materials, it's entire costs while being run, then the costs of recycling it.

I'm sure they may be "skewed" but they Prius, while good on fuel, is pretty poor in most other areas - made all over the world, two engines using nasty chemicals, etc.

Agreed with Matteeboy.
Also have to dispose of the large batteries! Nice.
I've also read about this somewhere. Just can't recall the media source.

Saw a Lexus RX Hybrid yesterday. It was doing a 3-point turn in complete silence as I walked passed. It then pulled off and the engine fired up. A hybrid SUV does'nt make sense to me either.

Thanks. I do understand the principle - it's just that although I've heard claims before that the Prius is a cradle-to-grave disaster, I've never seen a more detailed breakdown of where the figures come from in order to assess how complete or accurate they might be.

I'm genuinely interested to know what the score is - but somehow I can't see Toyota being too keen on providing the results of such an analysis

BTW did anyone see Evo this month? Unlikely as it may be, they tested the Prius against the current Fiat Panda - a car of not dissimilar load capacity, but half the price. The Prius' fuel economy was just 10% better...

Andy - Read the Evo article too. The Prius weighs a load more, uses more tyres, brake disks and pads, etc, etc and those batteries are just nasty.

I've had a search but can't find the source, however there are plenty of forums ranting for and against the topic!

The best off-roader in existance though. You'll find that they carry on for hundreds of thousands of miles and last decades so their cradle to grave cost is not much either.

Seat Arosa PD TDi does that now 76MPG. Keep it long time then get rid, saves the evironment, buy and keep

TG covered this a few issues back "Green Edition" Koneigsssseegggggg on the front. Most L/R's are still on the road so no recycling issues etc. Excellent explainations to defeat the "Huggers".

Why per mile? You need to ascertain the environmental impact over the lifecycle of the car (i.e. incl manfacturing, scrapping etc.). Also CO2 is not the only enviromental impact a car has.

Miles travelled is the value. If a car's useful life is twice as long, the manufacturing and scrapping costs per mile are halved. Yes, there are other environmental things to worry about, but CO2 is what's got everyone worried right now.

It's okay - I actually like them (in-laws have had four, grandparents in law have one now - All 4.2TD VXs) but it seems that anything with a big engine gets bashed yet Toyota make one of the biggest 4x4s out there!

Done proper green laning in one - All luxury leather seats and loads of toys but VERY capable on a tractor "only" track!

The original paper appears to have been disappeared.

[tinfoil hat]I had a copy of it as a pdf file on my own machine, but that's gone too...[/tinfoil hat]

Anyway, there's a rebuttal of it here

(Edited to add the original paper is available from Automotive Energy)

I'd still rather be driving a Prius than a Hummer.

If you want to point a finger at a real contributor to CO2 (although CO2 is probably not causing natural global warming, just supporting taxation plans) then consider the 400kg per year the average human exhales and multiply it by 6.6 billion

The pub scientists aren't worried, but a large proportion of the real ones are.

But it's a moot point, the Prius wasn't built to save money, it was built to reduce CO2 emissions so $ per mile isn't the measure to compare.

I wonder if the D-D figures for the Hummer include references to it's heritage, namely the HMMWV which was a military vehicle involved in the "odd war" that America decided to start - so the true overall "carbon footprint" must be pretty massive!!!

Then again, the Prius runs on electricity, so by the time you have included the entire infrastructure costs for the national grid, it looks pretty bad

...or, maybe, just maybe, statistics are being manipulated

Well I am a tree hugger and I think the Prius is a terrible car in many ways. Not least of which when I drove one for a day it averaged 16mpg around town! Really good

So that blows your argument!

You should consider changing your driving style, I managed an easy 50mpg.

It's not like I was boy racing it or trying to make it have bad mpg - I was simply driving between offices in stop start traffic around town - something the Prius is supposed to excel at.

Also given how much plastic it uses it must have already used a few barrels of oil just on the interior!

Awful car.

PS I thrash the nuts of my BMW530d Touring and my Suzuki Swift and they both do 35mpg at worst. I am sure I could easily drive them both over 40mpg.

...er, and just exactly how did you determine that it "averaged 16mpg"???

It has a read out telling you how economical it is - it is a dial with a little halo above it

I beg to differ There are plenty of scientists out there who dispute the claims of the enviroment fundamentalist movement, they just aren't permitted to voice their opinions
