Sample quote

Mazda is suggesting what no automaker wants to sanction: that lithium-ion batteries degrade over time, reducing performance and range, to the point where it could negatively affect long-term ownership. There aren't enough EVs with six-figure mileage to say for sure, but it seems accurate that fast charging, depleting the battery to empty, and age can all reduce battery health.

Mazda is also suggesting another hot take: EVs with large batteries are bigger polluters over their life cycles than EVs with smaller batteries. This makes sense, given the energy needed to replenish a battery at several times the capacity of the MX-30. Mazda cites a life cycle assessment by the journal Sustainability and quotes an unnamed figure of the European Union's average CO2 emissions from producing electricity in 2016 to say all this.

Yes, diesel cars pollute with other gases and particulates at the tailpipe that EVs don't. But at least the CO2 emissions from driving an EV are mostly understood, since battery-electric cars can only run as clean as the local electrical grid. Then there's the humane problem of people in poor countries mining rare-earth minerals, and the environmental impact of extracting lithium.

Many have been saying this for a very long time but of course the greenies tend to ignore reality.

Let's assume that over the lifetime use of vehicle, EVs and ICEs have the exact same CO2 emissions. The EVs still win because the bulk of their emissions generally aren't in populated areas where people have to breath the exhaust, and then have the subsequent health issues (and if they don't have health insurance, the rest of us get to cover their health care costs anyways, but I digress...).

But in reality, EVs, especially when produced using renewables, have lower lifetime emissions, in addition to not making exhaust in populated areas.

While some current batteries from some manufacturers are pretty terrible and may need replaced to restore range, it won't be like that forever. Tesla is working on a million mile battery right now. They're already good for 500k miles.


If you ever find yourself in a fair fight, your tactics suck.

I wouldnt believe anything Musk says. He'll say and do literally anything to pump up the stock price - loves to "debut" vehicles that are nowhere near production or even have a place to be built either, I can't believe so many people are that easily fooled.

Solar energy (PV/wind/etc) "charging" a flywheel-driven car is the way to go.

I've made more than a few dollars buying and short Tesla stock based on Musk's antics. I bought on his "funding secured" claim, then sold and shorted it in time for the SEC to come out with it's investigation statement. Plenty of instances of that happening. Musk wild claim, buy and sit for a day or two, sell and then reality hits and short it for a day or two and cover. Wee.

Right, because we all know power plants are out in the middle of nowhere. eyes

I think that anyone who lives in a large urban center should be forced to buy an EV. If what said above is a positive, that the bulk of emissions are in these areas, then eliminate all ICE vehicles in cities and let us drive whatever the heck we want everywhere else...


The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

The calculations are pretty complex but that sounds about right. Electric cars move the smokestack somewhere else but don't eliminate it, at least not today. But electric cars can be charged at night which helps to even out the grid so that is good.

I've had a Leaf for a few years now and I think electric cars are great for a bunch of reasons that have nothing to do with pollution or being "green". Almost zero maintenance, charge at home, quiet, simple, no warm up period, lots of torque at low speed, heater and defrost blow hot as soon as you start the car, no exhaust system to rot out, brakes last a long time due to regen braking, used EVs are super cheap to buy, etc.

If I knew that electric vehicles did not mean the end of gasoline powered vehicles, I'd sure have more of an open mind to them.

That's more or less what some areas are doing by announcing ICE bans in urban areas in the future. But, I don't really like that idea, since by the time the bans go into affect (2030+), EVs should be much more competitive with ICEs, so like Andy, they'll be bought because they're better, not just because of pollution or a desire to "go green".

I see these future bans as furthering a sort of "urban vs rural" divide, which leads to opinions like this:

I can see a point in the future where EVs are price and usefulness comparable, so most people will choose them, at least for daily drivers. At that point, the remaining emissions from the ICE vehicles shouldn't be enough to really worry about.

I don't think force is a good word here. I believe the local and federal gubmints can give tax breaks to make ownership attractive for city folk. Then leave more octane for me! devil

There is a company in California that has many 300,000 mile Teslas. If I remember correctly most have the original batteries. If I find a link to the article I will post it.

Ford Motor Co said on Monday reservations were full for the high-end Mustang Mach-E First Edition electric sport utility vehicle.

Ford did not provide details on how many reservations it took for the First Edition, which sells for about $60,000, but has said global production in the first 12 months for all versions of the Mach-E is limited to 50,000 vehicles.

So how accurate is that an EV battery's lifev is really just dependent on rate of charge, depth of charge, temp?, rate of discharge, and charge cycles? Seems like an on board real time display of calculated used lifetime battery life would be rather useful, since so many here are mentioning miles on an EV, which means relatively little it seems..


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

All those are factors that affect life. Same with your cordless power tools and laptops etc.

Age and temp are big factors.

Seems like an algorithm wouldn’t be that hard to incorporate many of the variables and display some sort of ‘remaining life’ metric, but automakers might be slow to embrace that idea. A calculation of total charging and discharging watts would cool.

I'm pretty sure the current EVs do have a readout of battery capacity remaining/range at full charge.

Leaf's have some sort of battery bar width.

Tesla's show the current max range whenever you charge to 100% (I think it shows an estimated max range when you charge to lower amounts too, or you just do the math, xxx miles at 90% charge is yyy at 100% charge).
