Uh,???, that is not how it works. The highest gear ration and the lowest gear ratios aren't set by the number of gears.. That is set by an engineer based on expected usage. More gears just allow the car/driver to pick a more efficient gear for a given speed. Ex: https://media.ford.com/content/dam/fordmedia/North%20America/US/product/2021/mustang/2021-Mustang-Tech-Specs.pdf https://media.ford.com/content/dam/fordmedia/North%20America... Note that the top end gearing is pretty similar between the manual and automatics. There is a larger difference in 1st gear, which implies that the automatics might launch a bit faster, although I'm no expert it might just be compensating for the lack of being able to dump the clutch. Also, it is possible to build manuals with more gears, it just isn't usually done for weight and ergonomic issues unless your driving something like an 18 wheeler.
