Hey, I'm all for discussing the numbers. I'd just prefer that they're real numbers, not made up numbers.


OK.

I don't really have time to find real exact numbers.  The googles said sedans are 30% more.  And SUVs could be 2.5X more.

If you care to dig further knock yourself out.  I'm spending all my cycles worrying about the college football playoff...

I get you, brotha. But you're an engineer. You're numerate. 

Didn't "2.5X" just throw up a little red flag in your brain like "hmm, that doesn't sound right"?

Honestly I didn't really care enough to put that critical thought into it...?  My guess is there is one example of such, and that's the one the google picked.

  • Single-Axle Weight: This weight number refers to the total weight on single axles not spaced more than 40 inches apart from other axles. You may not legally have more than 20,000 pounds on a single axle when traveling on the Interstate System.
  • Tandem-Axle Weight: This refers to the total weight on consecutive axles with centers spaced between 41 and 96 inches apart. On the Interstate System, the Federal government limits your tandem-axle weight to 34,000 pounds.

Found this on line.  I don't think any car would come anywhere close to these limits.

Fair 'nuff.

But yeah, increased weight will bring problems. 

Hopefully as battery capacities improve, it will start to pull back some of that weight increase. For example, it's thought that if the solid state battery can actually come to fruition, it's something like 30-50% higher capacity per kg than lithium-ion
it's something like 30-50% higher capacity per kg than lithium-ion. 

But hopefully all the talk about solid state batteries is technically (and economically) achievable, and not just hopium.

Solid state batteries seem like a white paper dream right now, but I suppose ya never know.

Says he paid $56 K for that Tesla and compares it with Toyota Camry/Corolla, in different spots.

The newest Camry is hybrid only, probably around 40 mpg which is higher than the 26 mpg used above.

Toyota's hybrid battery guarantee, 10 years/150K miles, is all I need to buy one of their hybrids.  Not so keen on an all electric vehicle living in the boondocks.  Maybe when an electric vehicle battery charge takes less than 5 minutes and is good for 400+ miles.

The battery warranty on all EVs and PHEVs is 100,000 miles.  

I think we could see recharge times of 15 minutes from 20% to 80% fairly soonish.  That last 20% is slow at the moment.  The claimed Toyota SS batteries are interesting if they become real.

Nope, it's adequate as a second though.  Motor Trend is not my favorite car mag, but it's notable the new Prius is pretty fast.
