“If our car’s battery continues to erode at this rate, it will qualify for replacement under Tesla’s warranty.”
Yes, although as I provided,
Our battery's degradation thus far equates to a drop of roughly 2.9 percent in pack capacity every 10,000 miles, which, if it continues at this rate, would put us at 65 percent capacity at 120,000 miles. That's under the 70-percent-capacity retention specified in Tesla's eight-year/120,000-mile battery warranty for the Model 3 Long Range. However, Tesla makes it clear that in the case of a warranty claim, the car won't necessarily get a new battery, but one that at least meets the minimum 70 percent threshold.
None of this means the Telsa can not be more economical than a comparable gas (or even diesel?) but that there are other aspects that must be factored in, this being one of them. But with advances in battery technology I myself think electric is superior, as long as charging supply holds. Nuke power is sadly non-PC.
