Battery based electric vehicles of today and tomorrow.

No one gets an ideal Rankine (note spelling) cycle. Lots of time and effort is spent on turbines to improve efficiency. Real world processes are not isentropic.

I think 4-5 more inches of height of seat off the ground of the Model Y would be doable but a Subaru style would be nice.

Never had a 4 wheel drive vehicle until 2017 when I bought a base model 2010 Forester with 105K miles with the full service just completed including new head gaskets for $6K. I went to look at the Outbacks and was impressed but the new prices was outside of my one payment policy. I was in Clarksville TN so I got back into the car and checked Craigslist. This car was south of Nashville so I called the guy and got him down to $6K IF the car met my expectation based on photos and his sales pitch. 40K miles later I am still pleased. Next year I picked up our 4WD 2010 F-150.

I know Telsa wants the best range possible so the shape of a Outback or Forester would have more wind drag but I would be fine with a 10% lower range. Subaru just stated they plan to be all EV by end of 2030.

The Forester has a 2" receiver hitch added and it does fine with a 1000 pound Zero Turn mower. It has the auto/manual 4 speed and I use the manual some most local trips. Love the regen stopping of the Leaf.

Subaru PR department can make whatever marketing claims they want. Besides that I doubt they would turn away all ice loving customers, the simple fact in the way, is that the US electric grid is not strong enough for everyone to charge EVs, and can not be made so, in 10 short years. So for now its just talk.

While the power grid is not a remote issue in the USA the EV makers will not be able to build 77 million EV's a year to meet current annual sales of new vehicles today. It will be 2025 before Tesla can be building 8 million cars and trucks per year.

The move to will happen over time as gas and diesel engine production ceases.

I do not know what to make of the e-tron's future. Today (25 Jan 2020) a test drive offer came in mail. While I understand the Audi e-tron and Porsche Taycan share the J1 chassis the offer was good in the USA between August 31, 2019 and 31 December 2019.

Did some postal worker hide this promotion under a bridge somewhere until after the Christmas rush? A 2.5 ton EV with a range of 209 miles carrying a $75K price tag up front is not going to be an easy sale I expect but I do not see how mailing a test drive offer with a website address that is a month expired can be helpful?

The grid is more than capable already. EVs charge at night. Utilities practically give away power at night because they have so much available. Consider street lights? Unmetered. Utilities get a tax credit for "donating" the power. The tax credit is worth more than the power.

Some utilities may donate power for lights, but they don't around here.

The grid is not more than capable now.
Your argument is conveniently oversimplified.

While peakers idle back during nights, they do not have the capacity to charge 278 million US vehicles. On a minor note, many of these are fossil fuel plants, so, so much for having a green plan for EVs

Of probably 100 technical issues, heres a couple:

Forcing 278 million car owners to only charge at night. Think summer vacations, holidays where millions drive long distance and need to day charge. 2nd and 3rd shift workers.

Power plants need maintenance shutdowns. Can稚 do that if there痴 a full load at night and additional load during the day. Millions of step down transformers in every neighborhood will see their efficiency drop as the load increases.
Transformer and fuse failure rates will increase with a 278 million car charge load added.

Crowded neighborhoods and apartments dont have the electric robustness or smart technology yet to charge such a high watt density area.
Ive just scratched the surface of hurdles. Like I said the electric grid is not strong enough, and wont be in 10 short years. You cant add a huge load to an existing old system without adding to it and maintain the existing reliability. Its simple math.

Yes it is just simple math yet you don't seem to grasp it.

Are you going build 278 million EV's overnight or in the next 10 years?

The grid is fine and will continue to be so.
