When it comes to gearboxes in battery-electric vehicles, the more may be the merrier. That's one theory, and Plug In Cars says that the standard, single-gear EV configuration may eventually go by the wayside as engineers figure out how to better use multi-gear configurations to improve performance and range. It's an argument we've heard time and time and time again, but the added weight and complexity of a transmission means it's not been a popular choice in real-world used.
