    Good point, but what powers your ancient combustion engine?

    Ok, I'll admit it, electric cars don't interest me.
    Im "old school" I like piston engines, steam included although that's external combustion, but either way I like the moving parts and everything they contribute to propulsion.
    Jet engines............ eh, they're cool, they're fast, actually kinda scary with those huge fans on commercial airliners:eek:
    Jet powered KW's or jet powered anything that originally had a piston engine WILL go crazy fast, no surprise there, but again, it doesn't interest me.
    Guess Im old fashioned:p
    Electric cars may/will become the norm I suppose, so will a lot of other changes that I probably wont see, and some changes happening right now.
    As R.E O Speed wagon sang "Roll with the changes" LOL, Im kinda dragging my feet!

    I have been working on a confidential project the last 8 months at the engineering company where I work. It is a grass-roots lithium-ion battery recycling facility for electric car batteries. We should be starting detailed design in a couple of months. We were surprised by the Tesla announcement when it came out. Still, there should be plenty of batteries from the other companies' electric cars to recycle.

    And more bad news for Tesla haters going on and on about replacing battery packs: the Tesla battery pack is designed to outlast the vehicle.

    Tesla: Battery capacity retention averages 90% after 200,000 miles

    Tesla: our battery packs are designed to outlast the vehicle.


    In the "2020 Impact Report." Tesla reiterates high battery capacity retention (low degradation) in its electric cars.


    According to the company's data, the average vehicle battery in Tesla should still have about 90% of its original capacity after 200,000 miles (322,000 km) of usage.


    "Capacity retention of Tesla vehicle batteries averages ~90% after 200,000 miles of usage"


    That's a very good result of just 10% battery capacity (and range) degradation: 1% per 20,000 miles (32,200 km).


    Assuming 250 miles per full cycle (just for illustrative purposes), it's also about 800 cycles with a degradation rate of 1% per 80 cycles (or a higher number of partial cycles).


    That's a lot, especially since typically a car is scrapped after about 200,000 miles in the U.S.
    In Europe, it's 150,000 miles (241,000 km).
    Tesla's approach is to design the pack in such a way so they could outlast the car.


    In other words, batteries should not be a problem and besides the rare faulty battery, the normal user probably will never have to worry about replacing the pack.


    Model S/X data

    Just like in the previous years, Tesla shows a chart with battery capacity retention per distance traveled for the Model S (produced since 2012-2020) and Model X (produced since 2015-2020).


    Those two cars are equipped with cylindrical battery cells (1865 format, NCA lithium-ion chemistry), supplied by Panasonic from Japan.



    As we can see, vehicles with mileage between 150,000-200,000 miles (241,000-322,000 km), on average, still have more than 85% of initial battery capacity (the battery degradation is below 15%).
    Actually we can see about about 88% at 200,000 miles (red line).

    Notes:




      • the initial battery capacity fade is higher in the beginning and then stabilizes at a slower rate
      • we estimate (from the chart) that the first 5% of battery capacity is gone (on average) after about 25,000 miles (40,000 km)
      • another 5% (total of 10%) is gone (on average) around 125,000-150,000 miles (200,000-241,000 km), but it's difficult to estimate because the curve is really flat
      • after 200,000 miles (322,000 km), on average, the capacity degradation is below 15% (the car still has more than 85% of the capacity and corresponding range)
      • the lowest capacity within the standard deviation (see wiki) is above 80% after the 200,000 miles (322,000 km), but there might be cases worse than that (the population of those cases might be 10-20% we guess)
      • there is a higher variation in the high mileage results (150,000-200,000 miles) as there are simply fewer cases and some might be very specific.
      • keep in mind that time, temperatures and other factors (like how long the battery stayed at a high state-of-charge levels) also influence the battery degradation.
    For obvious reasons, the chart does not include the data for the latest refreshed Model S/Model X.
    The new versions of Model S/Model X (from 2021) are also equipped with 1865 battery cells from Panasonic (Japan),
    but both the packs and modules have been fully redesigned. Their battery capacity retention might be different.

    We can't say anything about the battery capacity retention in Model 3/Model Y, equipped with 2170-type cylindrical cells (various suppliers - Panasonic, LG Chem's LG Energy Solution)
    as well as prismatic LFP cells (CATL in China).
    We would love to see a similar chart specifically for the Model 3/Model Y, especially since those two cars already saw more than a million units sold.

    Last year I drove a Porsche Taycan Turbo for a week.
    If you're a car guy, you will fall in love with it.


    Here's the quickest (not fastest, that has to do with top speed) production car in the world, doing a few of those boring 1/4 mile straight track runs that some people call a sport...:cool::p:D


    ELECTRIC REVOLUTION * Quickest Production Car EVER *
    1,914 HP Rimac Nevera 1/4 Mile Testing


    We take the all new 1,914 HP Rimac Nevera for it's first run down a real 1/4 mile drag strip and set a new world record for the quickest production car down the 1/4 mile.

    I worked on hybrid Toyota’s when they came out.
    Nothing exciting. But the Camry let a deaf father speak w his son. The cabin was so well sealed. He could hear in it. That’s it, best I know.
    Oh, the electric rear diff in the highlander makes like 35hp. Enough to kill you in a go cart.
    That’s it. You can keepem.
    I’ll burn fossil fuels and enjoy them.

    just think of little kids playing with matchbox n hot wheels not making vroom vroom noises.
    Or if they make the noise their parent says
    Knock it off jr. Lmao.

    vroom vroom ttf !!!!!!!. Lol.

    The two quickest (fastest is something else) production cars in the world in a dragrace.
    Europe vs. USA:

    The Nevera 0-60 mph in 1.85 seconds, making it the fastest-accelerating production car in the world.
    According to the Rimac Automobili, it will accelerate from 0-100 mph in 4.3 seconds, 0-186 mph in 9.3 seconds, and on to a top speed of 258 mph.

    On 13 August 2021 The YouTube channel "Drag Times" tested a Nevera at Famoso Raceway, Bakersfield, California, USA:

    0-60 mph (1ft): 1.90s

    0-100 kph: 2.00s

    0-100 mph: 3.61s

    0-130 mph: 5.36s

    0-150 MPH: 6.88s

    60-130 mph: 3.42s

    100-150 mph: 3.27s

    100-200 kph: 2.95s

    1/8 mile: 5.64 @ 132.33 mph

    1/4 mile: 8.58 @ 167.51 mph

    I've done a .93 60 foot at Famoso. 660. 3.7 @ 206 mph. Although some of the most fun and exhilarating experiences you can have, it is all irrelevant when state speed limits are put in place.
    Shape, materials, and powerplant is all about "personal choice".

    agreed! I’d be surprised if those batteries handled -30 for a few months....

    Last Saturday there was a dual motor Tesla out on Woodward smoking everything, including C8's and a McLaren 650s

    Pretty quick for an egg shaped mini-van, but no thanks!

    Nailhead in a 67...

    Ok, you made your point.. OOOOHHHH cool I want a testla.. :rolleyes:

    Whatever.. this is V8buick.com.. and from now on, any thread I see about electric cars will be deleted immediately. You've gone beyond the point of annoying us old fools that like gasoline engines.

    I am sure there are plenty of boards on the internet to discuss EV's, but I won't have you tormenting my members here anymore.

    Now you want to talk about your nailhead in your 67, we are all ears..
