400 miles? Even Tesla's Model S doesn't go anyway close to that under normal driving conditions. Model 3 will get 200+ miles, at best maybe around 250 for the top model.
Edit: Yeah missed the k. Never heard that one brought up. Also doubt Tesla's will last much longer.
I think you missed the "K" at the end of the "400" in the post you replied to. The part I'm wondering about is why the Tesla could "conceivably" go 400K. A modern diesel could go 400K, but a Tesla will suffer the same problems the diesel would with rotting body panels and interior, and a whole host of problems not related to the drivetrain.
I have no idea what makes a diesel die. Can you give me details on diesel death and what the other problems not related to the drivetrain that one would expect are.
Mechanical wear, the rings don't seal as well against the cylinder walls as they used to. Valves don't sit in their seats as tightly as when new. And so on. As for other problems, I already listed a few. Think of the niggly things your last old car had. A Tesla, diesel, or any other car is not immune to those problems.
