You think $500 is bad? Wait until you have to rebuild the motor and transmission. Ok, put simply a ICE engine and transmission will last ~200k miles each. An electric motor (no transmission necessary) should easily reach 1 million miles. Should be more than that too, I wouldn't be surprised if most decently designed and built ones reach 1.5 million miles. That's 4-5 engine and transmission rebuilds/replacements minimum compared to an electric motor. That's not including major things like timing belts.

And as this article says, batteries are lasting a long time. I was hoping they gave a milage but they didn't. From what I've read they should be going 300k, so better that ICE rebuilds. And batteries are getting better each time.

Speaking of which:

nothing to do with being a Porsche ... scattered across the whole floorplan so replacement is a nightmare.

Scattered? Sounds like everything to do with being a Porsche. Good design is the battery is one pack.

Total cost of ownership also includes fuel, which is ~5x of electricity cost. That works out to about $1200 saved per year. Yes I know that ratio can change quite quickly.

I think you're talking disingenuously when you include battery replacements but not including engine rebuilds/replacements, so that's my last message.

I'm not talking disingenuously, I'm all pro-electric. In fact it looks like my next car will be a Taycan, unless something changes unexpectedly.

But counting engine rebuilds as an inevitable matter of life is rather disingenuous too. My other ("hobby") car is a 1977, so that's 47 years now, and still on the original engine and transmission. This is not an uber-reliable statistical anomaly: it's an unreliable piece of shit (a handmade sports car from a small manufacturer) but despite that, the block is still solid and original. Engine rebuilds are not common, unlike batteries which have an ever-degrading chemistry no matter how good they are.

And I strongly disagree on good design being a single point mass of over 700 kg concentrated in one block. The "skateboard" around suspension components and chassis is the most common design for a reason.
