That's an entirely fair comment - it would be interesting if actual statistic were available on this, but it's a bit embarrassing so manufacturer's don't seem that willing to share, or else deliberately obfuscate the information. Pointing out the EV's produce huge amounts of CO2 in manufacture isn't very 'on message'.
Theoretically it should be possible to produce these things using renewable energy, which should considerably reduce their carbon footprint, but that doesn't yet seem to be the case.
I personally hope that synthetic fuels gain traction - much lower embodied CO2 and less raw material in the vehicles, and the production and distribution of the fuel can also be theoretically carbon neutral.
VW have committed quite a lot of effort to going total-life CO2 neutral with their ID3, and presumably the rest of the ID range, and even publish facts and figures for it: https://www.volkswagen-newsroom.com/en/stories/co2...Theoretically it should be possible to produce these things using renewable energy, which should considerably reduce their carbon footprint, but that doesn't yet seem to be the case.

Interesting, it's time the world woke up to comparing whole life CO2 footprint if they're going to compare like with like. (Although it's pretty difficult to calculate, I admit.)
30 tonnes is a lot. Diesel produces 2.6 kgs per litre burned, petrol is more like 2.4 kgs. So based on your number of 30 tonnes, you're talking about 11,500 - 12,500 litres of fuel.

Awesome, Hummer produce an over 5 tonne off roader with a 1000 bhp that does sixty in 3 seconds and people start going on about it not being an eco vehicle.
We need to separate EV from Eco as concepts, ok , they dont blow smoke out and the electricity can be produced cleanly but there seems to be this assumption that anyone who buys one is claiming to be some kind of pious eco champion and that isnt the case.
This is not for those wanting to minimise their consumption, it weights almost twice what an original H1 did, and they were enough to trouble your trolley jack .
Five and a bit tonnes, sort of four normal cars weight.
Indeed. Whether it burns oil or uses Lithium, the raw materials are still extracted by exploiting and poisoning the poorest on the planet, trapped in corrupt nations and the end products are still sold to people who have absolutely no need for them.

And why the article thinks it is clever to use the distance between Basra and Baghdad as it’s example, a stretch of land synonymous with robber baron economics and the unnecessary misery of thousands is somewhat questionable.
Good times.
Just watched the Engineering Explained video on this. Lots of nice engineering. The GM boys can do some great stuff when they're allowed to. I know they've made some proper dross in the past, but cars like the Volt are genuinely very good pieces of engineering.
Anyway, its quite a shame its been wasted on some extravagant toy monster truck instead of being put into a more relevant car. Heck, they could have made a decent SUV instead and it would have been a better use of time/resources.
200 kWh+ battery pack and only 350 miles range (which it won't do). That only 1.7 miles per kWh. Its basically a gas guzzler in all but name. Just because its an EV shouldn't give carte blanche to be using as much energy as you want.

What is it with EV's & advertising wheel torque. Utterly pointless measure, probably bettered by any leggy old diesel range rover with a low range box.
QuiteDoing the sums, its basically a per-motor torque figure of around 330 lb-ft?
I mean, something like an Explorer with the 2.3 Ecoboost (peak torque 310lb-ft) and its first gear of 16:1 will do you nearly 5000 lb-ft of wheel torque (or rather output shaft torque?). So per-engine, its not that mad, its just got 3 engines!

AUTONOMOUS CRAB MODE PARKING
That's what I want to see this do. Not interested otherwise.
Mobile cranes can do this it is, when you first see it it’s rather brilliant and extremely handy in tight building sites! That's what I want to see this do. Not interested otherwise.
I’d love one of these, roof off with mates and couple bikes in the back heading up to forest trails and an actual useable range.

With a 200 kWh battery, this thing will have a CO2 footprint of more than 30 tonnes before it's even been driven.
This is not an environmentally friendly vehicle.

This is not true. You need to add up the fuel used/emissions produced for EVERY single litre of fuel which is delivered to every single fuel station in the world. The transportation of petrol/diesel is an energy consuming act in itself, and is often overlooked. The fuel used in simply getting fuel to the pump is huge.
Indeed. I agree entirely.But where do you stop? Do you have to pro-rata the emissions related to the steel production of the oil rigs?

More is more. I love how american and British 4x4s (landi, grenadier) are going down a road of super sizing everything.
Why do the Americans always want to remove doors, roofs and panels off road. You get sunburnt, dust, mud, mosquitos and rain come in. So everything needs to be in sealed bags.
What struck me with the new Bronco is that this is a 4 person 2 door off roader with the interior space of a Mini?
Chest height on a normal man. I am sure they will sell them to people who like to pretend they are doing things. But oh dear see one in person before you order it.

As for the Hummer. Really? It saddens me a bit there is actually a market for this sort of stuff.

But this is what all this stuff is, whether big 4x4s, expensive EVs, high performance sports cars. They are all toys for us to use and get enjoyment from. I don’t see why toys should be making people sad? As for the Hummer. Really? It saddens me a bit there is actually a market for this sort of stuff.

Tesla have made claims that they want their factories to be zero carbon and source from renewables. Whether they actually do or not is very debatable I think.

I'm pretty sure you can't make steel without emitting tonnes of CO2.
