QuoteThis country's semiconductor chip shortage is likely to continue well into 2022. Now, a Georgia Tech expert predicts that the United States will need to make major changes to the manufacturing and supply chain of these all-important chips to stave off further effects. That includes making more of these chips here at home.

QuoteBeyond 2022, Swaminathan says we need to work to revitalize the industry domestically. "We need to bring more manufacturing back to the United States," he says. "The U.S. government has recognized the importance of this semiconductor chip shortage and is trying to address the issue directly."

Seeing this across many manufacturing groups this push to reshore or onshore, but is it years late and a billions of dollars short?

mayday

simple fix, cut out the computer, bolt on a Holly duel feed double pump. If you want to go fast you gotta use gas.
My 1977 Vette has no chip problems those cars where built the right way. Now if you go EV IMHO your fucked and your in debt.
BTW, what does it cost to charge an EV? Havent heard squat about that

Yep.

Do you really need all that crap in a car??

Nope.

1) Fastrack permits to companies like Intel, AMD, NVidia, Seagate, Western Digital, LAM Research, Applied Materials, Qualcomm, etc... None of this 5 year EIR bullshit with 10 years of lawsuits. Some things are more important than a some flower loving fruit fly.
2) Reopen the copper, gold, silver and other material mines
3) Relax EPA emissions requirements so new power generation facilities can be built and see #1
4) Divert municipal infrastructure investments to support new facilites that have been committed to with heavy penalties for backing out, and/or closing facilities before sya 20 years or something like that.
5) Call out US based companies that have and do offshore to China and other communist supported enclaves for providing aid and comfort for the enemy

Just a few ideas. Will things be more expensive? Sure. Some things are more important.

I've tossed about the idea of buying one for my wife to use as a daily driver for work.  Where she works, there is a free to the public charger that she could use to keep it charged without costing me a penny.  Otherwise, if I had to keep it charged on my dime, I'd have to do the math to determine the true cost, but I'd still guess it would be less costly than gasoline and would fluctuate much less.  I don't know about other states, but here, electricity is regulated as a utility where gasoline isn't. Plus with EV's, you don't have to worry about nearly as much maintenance.  Brakes last longer, no oil changes, no air filters, no belts, no transmission or tranny oil changes.

ok, lets discuss. Why would the brakes last longer? Do they use the motors to stop? what if a cell goes dead, price for that battery. We live in the cold and we all know how battery's do in the cold. I do like the new F150 Lightning but but my almost payed off 2017 F150 3.5 eco boost only has 26,000 miles on it and it will probably out live me

Brakes last longer because of regenerative braking.  Essentially the motors turn into generators that back feed power to the batteries causing drag to slow the vehicle before the mechanical brakes kick in.  Even on my hybrid Rav$, the brakes easily last over 100K miles before needing replaced. 

As for batteries in the cold, from what I understand, the batteries are pretty well protected with warming/cooling systems to keep them optimal during use.  I think this warming may impact the range in the winter, but may have less of an effect if parked in a garage on charge.

EV's aren't for everyone, and I'm still up in the air about them myself.  Also, people that think they are "Greener" than an ICE vehicle, haven't really looked into them much.  I wouldn't be going after the "Green" other than money savings over the life of the car which I'm still working out.  I'm hoping in the next few years when I'm ready to make my next vehicle purchase I'll have it more figured out. :D

Not defending EVs as I see the many downfalls of them as well.

EVs use regenerative braking to stop, so basically using the electric motors to stop, like a jake brake. Also you rarely use the brakes, the gas pedal is like a golf cart, press harder to speed up, less pressure immediately slows you down and releasing will bring you to a relatively quick stop. You can disable that however and use the gas brake pedals like a normal vehicle.

I've heard battery replacement is around $20k for a Tesla, however rebuilding can be around $5k. If one of the around 5000 cells goes bad, yeah, it gets expensive.

Cold is cold on a battery, leave them outside in the winter and they will be weaker. Store them in a warm garage and the battery will be stronger. However it should only take a few minutes for the battery to come up to operating temp while in use.

Interesting to hear more.
personally I don't use breaks, (they just slow you down) :hrhr:
so, would I need to heat my garage to 70 degree's all winter?
once you turn on heat or air conditioning how much drain on the battery's?
can you jump start them? what if it dies on the road? Now what?
carry a 500 lb generator with you? oh wait!! that needs gas
gas is always just down the road, an outlet isn't
there still has to be oil, grease somewhere. do some still have axle's?

Here is the service interval recommended by Tesla

"Service Intervals

Your vehicle should generally be serviced on an as-needed basis. However, Tesla recommends the following maintenance items and intervals, as applicable to your vehicle, to ensure continued reliability and efficiency of your Model S.

Brake fluid health check every 2 years (replace if necessary).

A/C desiccant bag replacement every 3 years.

Cabin air filter replacement every 3 years.

Clean and lubricate brake calipers every year or 12,500 miles (20,000 km) if in an area where roads are salted during winter

Rotate tires every 6,250 miles (10,000 km) or if tread depth difference is 2/32 in (1.5 mm) or greater, whichever comes first"



I have heard they go through tires fairly quick compared to a standard sedan because of their heavier weight.


I have heard there are booster packs tow companies are now using to give a jumpstart so they can get to a charger, however it's likely the same price to just get a tow.

Garage can just be normal ambient temp, above freezing is recommended. After use and during charging the battery stays fairly warm for at least a few hours.

No axles, every wheel is independent. Which for offroad use would be huge not having that big pumpkin, oil pan, transmission, and axle killing your ground clearance.

Heat and AC will use battery. How much depends on a ton of factors. I believe Tesla uses a heatpump style system to both heat and cool, which in general are fairly efficient.
