How to Make a Golf Cart Faster: What the Makers Allow

Short answer: the only ways to make a golf cart faster that its maker stands behind are the ones the maker builds in: a factory low-speed vehicle (LSV) model rated 25 mph, a speed setting that an authorized dealer changes, or a high and low speed mode on the dash. Every maker whose warranty text we could read (E-Z-GO, Club Car, Evolution and ICON) says that modifying a cart to go faster than its factory specification voids the warranty; Yamaha’s manual says not to modify the governor. E-Z-GO adds that above 20 mph a modified cart becomes a low-speed vehicle under federal law, with all the equipment that requires. This guide quotes what the makers of the carts we sell publish, plus the federal standard and the Florida rules it links to.

How fast can a golf cart go from the factory?

A golf cart is rated at 19 to 20 mph or less; a low-speed vehicle is rated up to 25 mph. Club Car lists the Onward 2 Passenger at “High Speed (Level Ground) 19 mph (30 kph)” and the Onward 4 Passenger (2+2) LSV at “High Speed (Level Ground) 25 mph”. E-Z-GO’s Liberty manual says the cart’s “top speed is set at 19.5 mph (31 kph)”, and the Liberty LSV manual says its “top speed is set at 25 mph”. Yamaha’s Drive2 PTV manual gives “Maximum speed 31.4 km/h (19.5 mph)”. ICON’s FAQ defines a golf cart by a “Top Speed: Under 19 MPH” and an LSV by a top speed of 20 to 25 mph. Our guide to how fast a golf cart goes lists the rated speed of every cart we sell.

Buy the faster version instead of modifying the slower one

This is the route every maker offers. Club Car and E-Z-GO sell separate LSV models; Evolution lists an “Optional LSV package (additional fees may apply)” on its model pages. A factory LSV reaches 25 mph with the lights, mirrors, seat belts, windshield and VIN that federal Standard No. 500 requires (49 CFR 571.500). In Florida, as Martin County’s page relaying the state motor vehicle department puts it, an LSV “must be registered, titled and insured” and may be driven “only on streets where the posted speed limit is 35 MPH or less”. Our low-speed vehicle guide explains the class, and where you can drive a golf cart on the road covers the roads each class may use. 11 carts we sell are rated 25 mph in our product record and 7 carry an LSV rating; they are on our fast golf carts and street-legal golf carts pages.

Can a dealer make my golf cart faster?

On some carts, yes, within limits the maker sets. E-Z-GO’s Liberty manual says the cart “has been designed so that certain authorized service professionals are capable of setting the vehicle’s maximum level-ground speed to 25 mph (40 kph)”, and then adds that in any configuration above 20 mph “it is only permitted to be used off-road, on private property, or on private roadways where allowed” and that the cart “does not meet State or Federal LSV (Low Speed Vehicle) requirements and cannot be used on public roadways of any kind when the maximum speed setting exceeds 20 mph”. E-Z-GO’s RXV ELiTE manual lists the Freedom at “8 – 19 mph (13 – 31 kph) Programmable” and says “ONLY authorized E-Z-GO dealers should alter the vehicle using approved parts”. Yamaha’s fleet manual lists a “Check operation of speed limiter” row in its maintenance chart, which tells you the limiter is a maker-maintained part, not a user setting. In every case the person to ask is the maker’s authorized dealer, and the ceiling for a cart that is not an LSV stays at 20 mph on any public road.

Does my cart already have a speed mode?

Check the dash and the manual before you look any further. Evolution’s Classic Series manual describes an optional “High/Low speed mode selecting switch” next to the key switch: selecting H “will activate the cart to run at High max speed” and L the low maximum. Its D5 Series Plus brochure labels the same control a “HIGH/LOW SPEED MODE KNOB”. Epic’s E40FL specification sheet lists “Max Speed: 25 mph” alongside a “Turtle Mode Speed: 15 mph”. If a cart seems slower than its rating, check which mode it is in before you look any further.

What do the makers say about speed modifications?

They say no, in writing, and they tie it to the warranty.

  • E-Z-GO: “Tampering with or adjusting the controller to allow the vehicle to operate above factory specifications will void the vehicle warranty.” Its RXV manual: “NEVER alter this vehicle to increase travel speeds above factory specifications.” Its TXT guide: “E-Z-GO will NOT approve Distributor, Dealer or customer modifications converting E-Z-GO products into LSV’s.”
  • Club Car: the limited warranty “does not apply to any Club Car product that has been altered or modified to change its operation, performance, or intended use. Examples of this include modifications of the speed governor, braking system, steering, transaxle or other operating systems”.
  • Evolution: the warranty is void if the cart “shows indications that the speed setting was adjusted or modified allowing the vehicle to operate beyond specifications”, and any change that “increases the speed” beyond factory specification “will void this warranty”.
  • ICON: any modification that “increases the vehicle’s speed” beyond factory specifications “will void the limited warranty”, and “Improper electrical work could void the whole drivetrain warranty”.
  • Yamaha: “Maintain all safety devices including brakes, steering mechanisms, warning devices and governors, in a safe operating condition. Do not modify these safety devices as supplied by the manufacturer.”

The makers also describe these changes as a safety matter, not only a warranty one: ICON’s manual says such modifications “can result in property damage, personal injury or death”, and E-Z-GO’s says they “can create unsafe conditions and increase the chance of an accident”. We sell carts; we do not modify them or advise on modifications, and this page does not tell you how.

What happens legally above 20 mph?

E-Z-GO’s RXV manual states it plainly: when a cart “is modified in any way by the Distributor, Dealer or customer to operate at or in excess of 20 mph on public streets or roads, UNDER FEDERAL LAW the modified product will be a Low Speed Vehicle (LSV) subject to the strictures and requirements of Federal Motor Vehicle Safety Standard 571.500”. That standard (49 CFR 571.500, S5(b)) requires “Headlamps”, “Front and rear turn signal lamps”, “Taillamps”, “Stop lamps”, “Reflex reflectors”, an exterior mirror on the driver’s side, “A parking brake”, “A windshield”, “A VIN” and “A Type 1 or Type 2 seat belt assembly” at each seating position, among other items, and Florida then requires the vehicle to be registered, titled and insured. Our guide to why street legal is a local question covers that route, and our low-speed vehicle guide quotes the full equipment list.

So how do you get a faster golf cart?

In order: switch an existing cart out of its low mode; ask the maker’s authorized dealer whether your model has a factory speed setting and what the maker allows; or buy the LSV version, which is the only 25 mph that comes with road use and a warranty. If you are shopping, tell us where you plan to drive and we will show you the rated speed and the LSV status in each cart’s record.

Kandi America’s site could not be read by us, so no Kandi statement appears here. Rated speeds are the makers’ level-ground figures; load, grade, tires and battery charge all lower real speed.
