Mammoth Golf Carts Reviewed: Models, Prices, and What They're Worth Used

A Mammoth cart is a premium lithium golf cart from MammothEV, a young brand that designs its carts in the US and assembles them in Idaho. The 2026 lineup runs a 72-volt, 150Ah lithium pack and a 7.5 kW motor, and dealers list the 2-seat XR2 starting at $15,800. Used, they drop fast: a like-new 2025 XR2 was listed on Commonplace at $11,400, roughly 28% under that new price after a single season. And there's one catch every used Mammoth cart buyer needs to know before anything else. The factory warranty doesn't transfer to you.

I help people buy and sell big, awkward things for a living, and golf carts are one of the busiest categories on our marketplace. Newer brands like MammothEV are where buyers get stuck, because there's very little written about them beyond dealer pages. So below I'll cover who makes Mammoth golf carts, every model and its specs, what they cost new and used, whether they're street legal, the warranty problem, and what I'd check before buying one secondhand.

Who Makes Mammoth Golf Carts?

MammothEV makes Mammoth golf carts, and the company says it was established in 2021. Its site says the carts are designed in the USA and assembled in Idaho. One third-party review places the company in Gilbert, Arizona, with distribution in Boise and Gilbert. The same review says parts originate overseas before assembly, which the manufacturer doesn't address. I'd treat "assembled in Idaho" as the confirmed part.

One thing people get wrong: Mammoth isn't a direct-to-consumer brand. MammothEV sells through authorized dealers, and its site sends buyers to a dealer for pricing, financing and delivery. That matters for two reasons. You can't just order one online at a factory-direct price, and the dealer is who handles warranty claims and service.

If you came here searching "mammoth diesel cart," that's not this company. MammothEV's lineup is all-electric. There's no diesel model in it.

Mammoth Cart Models and Specs

The 2026 Mammoth lineup is four models, and they all share the same drivetrain. Every one runs a 72V, 150Ah lithium-ion battery, a Navitas 7.5 kW motor with a 600-amp controller, rear-wheel drive, four-wheel disc brakes and a 25-plus mph top speed. The differences are seats, length and weight.

Model	Seats	Length x width x height	Dry weight	Ground clearance
XR2	2	96 x 44 x 74 in	1,190 lb	11 in
XR4	4 (2+2 with rear flip seat)	120 x 53 x 82 in	1,390 lb	7.75 in
XR4F	4, all forward facing	126 x 53 x 82 in	1,510 lb	7.75 in
XR6	6	156 x 53 x 82 in	1,694 lb	7.75 in

Each model comes in standard or lifted height. MammothEV quotes a 40 to 50 mile range and a 3 to 5 hour charge on a regular 110-volt outlet. The cabin is where the money shows: leather seats with diamond stitching, a 10.5-inch touchscreen, three-point seat belts, proximity key fobs and a wireless phone charger. Buyers also get more than 200 body colors and 36 seat colors, which is why so many used Mammoths look one of a kind.

Here's the part that trips up used buyers. Older Mammoth carts aren't built to the 2026 spec. Dealer listings for 2025 XR2 carts describe a 5 kW AC motor, a 450-amp controller and a 30 mph top speed, and one third-party spec page lists a 48-volt lithium battery. So a used Mammoth cart can have a meaningfully different drivetrain from a new one. Ask the seller for the model year and the original spec sheet, and read the label on the battery pack. A 72V, 150Ah pack is roughly 10.8 kWh of storage, and you want to know if that's what you're paying for.

What Does a Mammoth Golf Cart Cost New vs Used?

A new Mammoth XR2 starts at $15,800 MSRP at dealers, and some color and seat packages list at $16,500. MammothEV doesn't publish prices on its own site. A third-party review says a 2023 XR4 listed at $14,500 and that 2025 pricing jumped to around $15,500 or more. I couldn't find published MSRPs for the 2026 XR4, XR4F or XR6, so get a written quote from a dealer if you're comparing.

Used is where it gets interesting. On Commonplace, a like-new 2025 XR2 with a canopy was listed at $11,400, and a like-new 2023 lifted lithium Mammoth sold from a $10,623 asking price. Against a $15,800 starting price, that's roughly 28 to 33% off in one to three years.

Mammoth cart	Price	Source
New 2025 XR2	$15,800 starting MSRP	Dealer listings
New 2023 XR4	About $14,500	Third-party review
Used 2025 XR2, like new	$11,400 asking	Commonplace listing
Used 2023 lifted lithium, like new	$10,623 asking (sold)	Commonplace listing

Why do they depreciate so fast? Two reasons. The brand is new, so there's no long resale track record to support high used prices. And the warranty doesn't carry over to a second owner, which I'll get to below. That second reason is the big one. It's also why a used Mammoth can be a good deal, as long as you go in knowing what you're giving up.

So what's a fair used price for a one- or two-season-old Mammoth cart? Based on what I've seen, about $10,500 to $11,500 for a clean XR2 or lifted 4-seater with a healthy battery. Pay toward the top only with paperwork showing the model year and battery spec. For how that compares with every other brand, my used golf cart price guide lays it out by brand, year and battery.

Is a Mammoth Golf Cart Street Legal?

MammothEV doesn't advertise its carts as street-legal LSVs, so don't assume one is. The carts do carry a lot of the equipment: a DOT-approved windscreen on every 2026 model, LED headlamps and tail lamps, and dealer listings show turn signals, brake lights, hazard lights, a horn, side mirrors and seat belts for every passenger. That's most of the list.

But equipment isn't the same as a street-legal vehicle. A true low-speed vehicle has a 17-digit VIN and a certification label saying it meets the federal LSV standard, and then your state decides whether it can be titled, registered and insured. If the Mammoth you're looking at has no VIN and no title, it's a golf cart, whatever the listing says.

Speed is the other wrinkle. LSVs are limited to 25 mph. Some 2025 Mammoth listings advertise 30 mph, and MammothEV's warranty mentions dealer programming up to 30 mph. A cart set above 25 mph doesn't fit the federal LSV definition. Before you plan to drive one on public roads, read my street-legal golf cart and LSV guide, and check my picks for the best neighborhood and street carts.

The Warranty Catch on a Used Mammoth

MammothEV's 10-year warranty is non-transferable, so a used Mammoth cart comes with no factory coverage. That's straight from the company's warranty page. It covers the "original retail registered purchaser" only, and it only applies to carts bought from an authorized dealer in the US.

For a first owner, the coverage is generous. Ten years on the charger, controller, electric motor and suspension. Lifetime on the frame (excluding drivetrain, suspension, roof supports, paint and corrosion). And a lifetime lithium battery warranty for 2025 and newer models. Wear parts like the windshield, tires, brakes and seats aren't covered.

It also voids easily. Non-approved tires, parts not authorized by MammothEV, or raising the speed past the dealer's 30 mph programming can void it. So even a first owner can lose coverage by modifying the cart.

For you as a used buyer, the takeaway is simple. Price the cart as if it has no warranty, because it doesn't. That's exactly what the used prices above already reflect. A Mammoth at $11,000 with no factory coverage is a different purchase from a $15,800 new one with ten years of it, and you should only pay used-cart money.

Compare that with a Star EV Sirius, which comes with a 4-year limited warranty and up to 6.5 years on the lithium battery new. I cover it in today's other post, Star and Sirius golf carts.

Mammoth vs Other Lifted Lithium Carts

Mammoth's main advantage over most competitors is its 72-volt system. Most carts in this segment run 48 volts. Here's how the 2026 Mammoth XR4 stacks up against a Star EV Sirius 2+2 on published specs:

Spec	MammothEV XR4 (2026)	Star EV Sirius 2+2
System voltage	72V	48V
Motor	7.5 kW Navitas	4 kW AC
Controller	600A	350A
Battery	150Ah lithium-ion	80Ah to 210Ah LiFePO4
Claimed range	40 to 50 miles	40 to 60 miles
Charge time (110V)	3 to 5 hours	5 to 10 hours
Factory warranty	10 years, non-transferable	4-year limited, 2-year bumper-to-bumper
Built	Assembled in Idaho	Simpsonville, South Carolina

More voltage and a bigger motor mean more pull on hills and with a full load. A shorter charge time is a real everyday win. The trade is price and age. Mammoth is a newer brand with fewer dealers, and there's not much history on how its carts hold up past a few seasons.

I've also reviewed Evolution vs ICON in the same segment. If you just want the most dependable used cart and don't care about the lifted look, a used Club Car or Yamaha is still the safe pick.

What Breaks First, and What to Check Before You Buy

There isn't much public complaint data on Mammoth carts yet, which is normal for a brand founded in 2021. One review said the reviewer couldn't find meaningful negatives, and mentioned a single customer issue that the company resolved quickly. Other buyers note the higher price compared with basic carts. That's thin evidence either way, so I'd focus on the parts that wear on any lifted lithium cart.

Here's what I'd check on a used Mammoth cart, in order:

1. Model year and spec. Get the year and confirm the battery voltage and motor. A 2025 cart and a 2026 cart are different machines.
2. Battery health. Ask the seller to charge it fully, then drive it 15 to 20 minutes with a hill. Watch the charge display. A healthy pack drops steadily, not in jumps.
3. Charging. Plug it into a household outlet and make sure it starts charging. It should finish in roughly 3 to 5 hours on a 2026 cart.
4. Touchscreen and electronics. Test the screen, key fobs, wireless charger, lights, turn signals and horn. Electronics are expensive to chase down.
5. Lift kit and suspension. On lifted carts, check for bent arms, worn bushings and uneven tire wear.
6. Modifications. Aftermarket tires, parts or a raised top speed tell you how the cart was used, even though the warranty doesn't transfer anyway.
7. Dealer access. Find your nearest MammothEV dealer before you buy. Parts and service go through them.
