I came to that same conclusion. I wonder if it helps on the V6?

Tesla Model 3 is definitively a very advanced luxury performance sedan that is going to continue to sell well for people who like performance luxury sedans. So if you like, for example, a smaller Audi sedan TDI or gasoline for performance, looks, luxury, etc. then the Model 3 Tesla will be pretty attractive to you. No doubt.

The folks in America that do not want/need a sedan will not be buying a Tesla Model 3, a Bolt, a Nissan Leaf, a Chevy Volt, etc. They will be looking at the latest shiny non-electrical SUVs and trucks with 0% financing and as many years to pay as possible, forecasting that the cost of fossil fuels at the pump will stay comparable to 1980's level, more or less, in the next few/many years (depending who you ask).

When I replace my Outback, it will be for something with a plug, and a sedan just isn't comfortable for this old body getting in and out. The Kona EV is attractive, but I'm waiting to see what VW is going to be bring out in the next year or two. They are showing off several cars with the ID tag that look interesting. Wonder if my VCDS cable is going to work on one?

The fuel savings with a hybrid over a conventional vehicle will vary from 0 to as much
as 20% or more based on driving conditions and so will not always be observed by
the published mpg figure.
A hybrid driven at a constant speed on the highway will net 0 improvement in mpg.
A hybrid driven in stop and go traffic (difficult to standardize) will significantly add to
the mpg.
I can see this in my own hybrid, a 2008 Ford Escape.

To gauge meaningful differences in efficiencies of a passenger vehicle with a certain power train vs other kind of power train we need averages with at least tens of thousands of miles/Kms/etc. of MPG (or liters per 100 Kms etc.).

True, but in regard to standardization: isn't that exactly what the EPA city driving cycle is meant to do?

Hopefully yes. It probably is mainly about trip length and time in heavy traffic.
For the non plug-in versions the city mpg can exceed the highway mpg.

This is true, but in practice the acceleration boost of the electric motor means you can get away with a smaller engine that runs more efficiently on the highway because it's at closer to full load. I guess this doesn't apply to to the car this thread is about, because it still has a 'full sized' 2.0 TDI.

I think that this technology has been around for quite a while. My 1960's vintage lawn tractor works this way. To add a modern twist with better efficiency, I know that regenerative variable frequency drives have been an off-the-shelf item in the industrial market since at least the 1990's.

The tough part with recapturing power in a car is having a place to put it that has enough capacity & a fast enough charge rate. Capacitors have the fastest acceptance rate, but only store a very limited amount of energy, even if they are the size of a trash can. Lead Acid batteries have a very slow acceptance rate, typically around 20% of their amp-hour rating when in bulk charging phase & much less when they are more than 80% full. The modern lithium based batteries have a fairly high acceptance rate & good power density, but they have other problems that are not well reported. First of all, the materials used in manufacturing them are very toxic. Second, the risk of fire is significant & putting out the fire can be a problem.

A few recent examples -

heh
go check out 'subcooledheatpump' on youtube, he had a chevy express van with a 30hp six pole induction motor hooked to a cobbled together VFD, 600V of car batteries on the DC bus of the inverter

The risk of fire is significant with internal combustion too. They catch on fire about every three minutes in the US. It's just that every EV fire makes headlines. So it's more an issue of public perception.

An EV fire is infinitely harder to put out. There is plenty of evidence to support that. Once that lithium starts burning, there's no stopping it.

Yes, they require a lot of water to extinguish. The good part is the fire generally developes more slowly than a petroleum fire, giving more time to escape.

Actually heated liquid lithium will react with water, thus adding another complication in fighting an ev fire.
