How to Make Your Golf Car Go Faster

Most new and used golf cars top out at about 12-14 mph—that’s a great speed for most people, but some of you want some more speed! There are several different options to make your golf car go faster, and we’ll cover all of them here. 

Golf Car Motor

One way to increase your golf car’s overall speed is to increase its motor RPM, and there are two ways you can do that: 

  • Use a motor with a higher rated RMP
  • Provide your current motor with more voltage

Both options have their benefits—for example, with the first option you can leave your voltage alone. With the second option, you don’t have to replace your motor. 

It’s important to remember, with this upgrade option specifically, that with some modifications, there’s a chance you may lose some performance elsewhere in your golf car. You’ll want to keep this in mind when you’re upgrading any part of your car’s electrical power system. If you want to avoid uneven power, ideally you should upgrade all of the related parts to maintain consistent torque throughout your car. If you treat upgrading your motor like an all-or-nothing project, you’ll be thankful in the long run! 

If you decide to upgrade your motor, we suggest upgrading your solenoid contactor relay and your electronic speed controller as well. 


Upgrading the tires on your golf car is probably the easiest—and cheapest—way to get more speed out of your golf car. Essentially, the upgrade comes with choosing a bigger size tire—you can get an extra 2-4 mph out of your car this way. This option is cost effective and easy, because it takes very little time and you can do it yourself! 

Depending on the size of your golf car, you may need a golf car lift kit to accommodate new, larger tires. If you aren’t sure whether or not you need one, call us! We can answer all your questions. 

Always keep your tires properly inflated for the best possible performance!


Increasing your golf car battery voltage is a foolproof way to get more speed and overall power. Like the larger tires, this upgrade takes very little time! First, you’ll need to find out what your current battery voltage is—you can usually find this information printed on the batteries currently in your golf car, or printed on the motor. If you still can’t find it, a recommended battery voltage will be in your owner’s manual. 

Remember to keep your batteries clean and free of corrosion and buildup, because dirty batteries will slow your golf car down significantly. 

Most golf cars are designed to work with a range of different batteries—but if you’re unsure, you can call us for a recommendation! We also recommend that, if you’re upgrading your batteries, you upgrade your battery cables as well. 


This might go without saying, but if you want the absolute best performance out of your golf car, make sure it isn’t being weighed down by unnecessary clutter! Routinely check its undercarriage for mud, stones or rocks, grime, etc. Get rid of any excessive stuff in your car that you don’t need to tote around. Take a few minutes before your ride to check any compartments you have, under the seats, etc. for things you don’t need to carry.
