It really depends. If by “offering 40-60 more miles” he means being able to fully deplete or charge your EV battery, that’s a good way of bringing down its longevity. A particularly scummy CEO might first hard lock your EV battery buffer so they don’t have to deal with insurance on battery degradation complaints, and only after it’s out of insurance coverage they would remove those locks to accelerate how fast your EV battery degrades, which generally tends to cost about as much as a new car to replace.
