I don't know specifics regarding The Villages Golf Cars, but I can state some generalities re: transmission gears:
Performance gears have been around forever in many different applications, like racing. However, they only made it into the golf car market in recent years. Performance gears not only include those designed for low torque, high speed applications, but also encompass those gear sets designed for high torque and low speed.
Since golf cars have a fixed gear set in a non-shiftable configuration (the differential), you have to choose a performance gear set wisely. Be sure to select the proper gears for your intended application, taking into consideration the terrain.
Most golf cars have a factory installed gear set (gas and electric) of about 12.5:1 ratio(the motor turns 12.5 times for each rotation of the drive wheel). This is a moderate gear ratio that provides reasonable speed (14 mph) for golf course use and adequate torque to pull up steep hills with 800 lbs of people & golf bags. If you install an 8:1 gear ratio, for instance, in a car that previously had a 12.5:1 ratio, it would increase the top end speed from about 14 mph up to approximately 20 mph. If you install a 6:1 ratio gear set, your top end speed would increase up to just shy of 27 mph.
