Thread: The New Defender

All good points roverrescue and 101rrs- but to be a game changer (and save the world) we need baseload power to come from the storage of renewables or hydropower or even nuclear. Then the emissions intensity drops significantly.

Yes but baby steps are needed and it is all progress in the right direction - Rome was not built in a day.

One would have hoped they'd have learnt something about that..... apparently not.

Its not production its been ripped apart to show components, i think it was at Frankfurt like this

Whilst I typically only drive 20km per day and could easily recharge overnight I would only do this because coal powered electricity is low cost. So a hybrid with a 50km range works - but in reality the extra upfront cost could never be justified.

Those switching to EV because they think they are saving the planet are misguided.

What I do like with the current P400 is they are making the supercharger efficient and this a clever solution to overcome turbo lag. I recall many used to slag off the electric driven supercharger in the past.

Actually everyone has the option to choose green power, it costs more, if you really care about the planet what do you do?

Yeah .. but, if you want a semblance of equivalency(say to the base model D200 Defer) you'd need something like 200 of them!
(with the side benefit that you have a bit more traction than just 4 wheel drive)

All good blackrangie,
I was just being "funny".

Is it though?! And Rome collapsed very quickly and was very corrupt and immoral.

Energy requirements and emissions for building an EV exceeds a standard vehicle. Once built, EVs certainly reduce your carbon footprint, but making the lithium-ion batteries could emit 74% more CO2 than for conventional cars.

Research shows that while EVs are emission-free on the road, they still discharge a lot of the CO2 that ICE cars do. To build each car battery—weighing upwards of 500 kilograms (1,100 pounds) in size for sport-utility vehicles—would emit up to 74% more C02 than producing an efficient ICE car if it's made in a factory powered by fossil fuels in a place like Germany.


For perspective, the average German car owner could drive a gas-guzzling vehicle for three and a half years, or more than 50,000 kilometers, before a Nissan Leaf with a 30 kWh battery would beat it on carbon-dioxide emissions. For larger 80 kWh powered vehicles it’s even longer before they level.

Data provided by Tesla is their power pack loses around 2.5% capacity per year, that Lithium isn’t recycled. A $110k Tesla 3 becomes useless for my needs in under 2 years as the range drops below my needs for a charge.

Whilst not quite as harmful, the next issue the planet will deal with after nuclear waste will be the huge piles of Lithium Battery packs.

Current technology just can’t meet emissions reductions and usability requirements for many. All that is happening is the construction of a lot of throw away vehicles.

Even the renewables to offset emissions aren’t coming in as good as expected:
Recent data on Wind turbines is also suggesting they aren’t balancing the books as planned - maintenance is higher than expected, emissions to maintain are higher, emissions to produce are high, emissions to install are high, damage to area around sites is high. (Have been directly involved in several projects from Wind to Solar to Hydro recently) and seen all the data.

What an EV is good at is Pollution / Carbon shifting, moving the smog and emissions from roads to a larger production facility elsewhere.

For the tinkerers- they’re good for learning and playing.
And cheaper to convert an existing vehicle as a hobbyist than buy a commercial production vehicle.

I find Goingbush’ EV conversion fascinating, and for his niche use it’s perfect. And I’m sure he had a blast building it too. It’s just not a practical vehicle for the wider audience.

The impacts and offsets are not as simple as first appear either... look at the weights of all these “moderately capable” EVs (Tesla 3 can do 600ish km) they weight nearly 2 tonnes. When every vehicle starts to weigh in that heavy that will increase road maintenance requirements, the Emissions increases to repair roads more often then needs to be factored in to emissions models.

Interesting times...

Perhaps a better simile could be found - the start of the collapse of Rome is usuually considered to be the start of the reign of Commodus in 177AD, and its final collapse the fall of Constantinople in 1453AD. Took well over a thousand years. Even if you just consider the "collapse" to be when the centre of government moved from Rome to Constantinople in 330AD, it still took over 150 years.
