The point I made was quite clear.
"There is little R&D to improve the IC engines in any transformative way."
Electric motors are mature technologies, too, as are batteries. There are no "transformative" changes there, "There is little R&D to improve the IC engines in any transformative way."

Batteries have been transformed. A Tesla car can do 325 mile in range.
A lot of bog standard small cells that have been around for ages. LiIon 18650s are used in everything from eCigs to laptops, and have been for years.Teslas really aren't any more efficient than any other electric cars. An original 2011 Leaf does 7.2km per kWh, on the NEDC test. A new Model S does just over 6km per kWh on the same tests.

Rarely. There's no point in having a smartphone here, because we don't have any mobile phone signal - let alone mobile data signal. Fortunately, I work from home mostly.

They haven't really - the only way Tesla have got that (claimed) range from an EV is to fill it with bigger batteries, hardly transformational.
20 years ago NO car could do 325 miles in range. That was a dream. They are here - they do it, is not `claimed`. Wise up. https://www.youtube.com/watch?v=5_VL_76BoC8
Batteries in smart phones do last longer. In my 5 year old Samsung S2 the battery lasted only 3/4 of a day for me. I replaced the battery a year ago with a larger capacity and now it goes the whole day.

I'm not sure that the relative size, luxury, weight and performance of those two vehicles makes for a particularly meaningful comparison.RayTay said:

Put a big enough battery in, and an Enfield 8000 would do that kind of mileage...<thinks, googles>
165Ah lead-acid batteries @ 48v = 8kWh.
35 mile range = 56km range = 7km per kWh... So about the same range-per-kWh as a 2011 Leaf, and better than a 2017 Tesla Model S 100...
In 1971... 46 years ago.
Now, I wonder what the official fuel economy of an equivalent 1971 internal combustion car is, versus equivalent moderns?

In the spirit of an Enfield 8000 being "equivalent" to a Tesla (or even a Leaf), I suggest a 1950's Messerschmitt bubble car at about eighty miles to the gallon.RayTay said:

I'm assuming you missed the part of my post where I said the only reason that smartphones last longer now is becuase of bigger batteries, so thanks for proving my point. https://www.youtube.com/watch?v=5_VL_76BoC8

And I'll also assume you mean no EV 20 years ago could do 325 miles in range. As I'm pretty sure my dad's 1996 BMW 525 td would do about 550....

That is one view. But the Chinese are dwarfing Tesla's battery production. Lith-glass, Lith-plastic and graphine are all pulling along in the background. Meanwhile the rest geared up for EVs. For anyone interested in reading (except RayTray obviously, he can't even manage 180 characters it seems).

I don't need 180 characters to get a point across. Most flat earthers cannot go more than 50 characters, so what is the point?

My Samsung battery 5 years ago was the biggest capacity available. Now for the same size it gives more. Your Dad's BMW 525 td is not an EV. Boy! Duh! Some mothers......And I'll also assume you mean no EV 20 years ago could do 325 miles in range. As I'm pretty sure my dad's 1996 BMW 525 td would do about 550....
Do you want to re-write what you wrote?

And if you read back your original post I was replying to, you suggested there wasn't any car that could do 325 miles on a tank, hence me mentioning an old 5 Series that would do it easily.
Perhaps instead of telling everyone to wise up some reading courses would be in order?

If your phone is lasting longer now as it did before with the same size battery, I would suggest that's the fact that you have a new battery,
When new I got 3/4 of day. I then got a whole day from my Smart phone with new larger capacity battery.It was obvious I was on about EVs not filthy diesels. It seems by 2020-25 they will be banned from all cities in the UK.

I regularly got 550+ mile range from my 1996 Citroen XM... and it was a petrol. 90 litre tank.You see, it's really very easy to increase range. You just put a bigger store in. It works for fuel tanks, it works for batteries. Magic, huh?

This explains your obsession with youtube links, versus - you know - actual scientific papers and debate.
You didn't believe the Youtube vids? It's not about believing/disbelieving anything - it's not about belief, period. It's about empirical evidence, and primary source documentation.
Let me put it another way - what did you LEARN from the youtube link you posted on the polymer battery? Voltage? amp hours? construction (outside of the electrolyte replacement?) capitalisation of the business? grants? product method? current issues and challenges? where were any of those clearly stated on that video?
Now go to the companies website and READ.
Then - after you do that - go and read primary sources on the underlying topic. Like "Thin film li-on battery limitation challenges issues" for a start.

Despite the hype, greenwash
No greenwash in Evs. they do not pollute cities. The amount of electricity to make a gallon of petrol is equal to its energy content. The IC engines waste 80% of the energy in the tank and also pollute like crazy. So:- pollution to make a gallon
- pollution burning the crap.
Wise up.

1) EVs have bi-directional powertrains. They can recover KE from the vehicles mass. On the official drive cycle, which is very gently, this doesn't make that much difference. BUT in the real world people are impatient, terrible, jerkly drivers who have poor observation and little mechanical skills. This is one of the reasons when measured real world NOx emissions from diesels are much worse than the official figures, because the official figures are driven by experts (and these days, robots!). So, terrible drivers get much better economy on a bi-directional powertrain, because they don't keep wasting energy into the brakes! Follow drivers on the road, i bet you £5 within 45 min you follow some muppet who brakes for every thing, including cars coming the other way, gentle bends, and who know what else.. In an EV, they get back something like 70% of what they just put in! This makes a big difference to overall real world energy consumption
2) Cold starts. In the UK the average temperature is something like 7 degC. The official tests are done at 25degC. Every time you cold start an ICE you are wasting huge amounts of energy warming up all that metal in the engine and gearbox. Over something like a 2 or 3 mile journey, starting at say 10degC, and typical passenger car ICE will do something like 15mpg. Over that same journey, and EV is pretty much unaffected (in fact, as resistance decreases with temperature, they can become MORE efficient....)
Add in the ever increasing proportion of renewables, generally lower road loads (less drag), and EVs are a no brainer, hence the headlong rush to bring them to market by all the manufacturers!
