At Tesla upgrades its electric motor on the road to have powertrains lasting 1 million miles the article title appears to say that Tesla is now offering a million mile powertrain on vehicles with a new design of the rear motor (non Performance cars). But the text of the article does not make any such statement. It discusses how there is a new part number for the main rear motor (not the smaller front motor or the rear higher horsepower Performance motor). The article speculates that it is the new rear motor design that is responsible for the significantly quicker 0-60 times for the non-Performance cars that appeared on the Tesla website recently. And that seems like a reasonable assumption. But on the S/X specifications pages the warranty language is unchanged, as far as I know. It says, quote: 8 year, infinite mile battery and drive unit warranty 4 year, 50,000 mile limited warranty The Electrek article does not specifically say that Tesla claims that their latest powertrains will "last a million miles". So where does Electrek get that figure from? I posted a comment in that Electrek article page asking for clarification.
