I'm sure they meant supercharged engine. But there is an error in the charge time section. It's not going to take 8.5 hours to charge at 80amp and 240v. That is like 19KW, so probably less then 4 hours from 0% which should never happen and most will not be range charging every day and will stop at 80-90%.
But the Model 3 doesn't offer 80-amp dual chargers, so that is completely a mistake.
