Gibbs Quadski: Redefining the meaning of “all-terrain vehicle”

By

Gibbs Quadski amphibious ATVOff-road vehicles claim to be able to go anywhere, but they can’t. Cars, dirt bikes, and ATVs can’t fly, nor can they swim. The FAA might have something to say about the former, but Michigan’s Gibbs Sports Amphibians hopes to achieve the latter. The Gibbs Quadski is the mutant offspring of an ATV and a jet ski.

On land, the Quadski behaves like a normal ATV, but at the push of a button the wheels retract and power is transferred from the rear differential to a propeller. That power (175 horsepower and 103 pound-feet of torque, 140 hp on water) comes from a 1.3-liter four cylinder engine from a BMW K1300 motorcycle.

As with any vehicle that is neither one thing or another, there are compromises. Despite its considerable size, the Quadski can only carry one rider. It’s also rear-wheel drive, which may limit its performance on tough trails.

Amphibious motoring also doesn’t come cheap. Gibbs has not finalized the price, but company representatives say the Quadski will cost around $40,000. That is a lot of money for a quad, even if it can drive on water.

The Quadski may be flawed, but that’s not surprising given how difficult its development has been. Gibbs has been developing amphibious vehicle technology since 1996, spending $200 million and accumulating over 300 patents. Until now, the result of all that work has been nothing.

Gibbs spent years trying to bring the Aquada, an amphibious car, to market, but it was torpedoed (no pun intended) by supplier issues and regulations. That’s not surprising given the checkered history of amphibious vehicles. The German Amphicar was a sales failure, and even the World War II DUKWs that delivered supplies in support of Allied invasions (and now carry tourists on “Duck tours”) were said to drive “like trucks in the water and boats on land.”

When it goes on sale in November, the Quadski could be the first amphibious vehicle to sell in significant quantities. Gibbs has dealers lined up in Florida, Texas, New York, and the Midwest.

Technical issues aside, why would anyone want an ATV-jet ski hybrid? It would certainly allow outdoors adventurers to travel as the crow flies, but on another level, its just plain cool. Now if only Gibbs could add some wings…

We’re finally getting to the fun part of automakers’ methodical quest to replicate their lineups with electric cars.

Performance versions of ordinary cars have been a staple of the auto industry for decades. But while we’ve already seen some variants of EVs boasting more power and more impressive stats — think Tesla Model S Plaid or Lucid Air Sapphire — the 2025 Hyundai Ioniq 5 N is the first to truly apply that format to an EV.

The Maserati GranCabrio Folgore is one of the best-looking EVs yet

Maserati is adopting electrified vehicles with open arms, and while that could potentially signal an identity crisis for the luxury Italian brand, that’s probably a good thing in the long run.

The company recently took the wraps off of the new Maserati GranCabrio Folgore, which is essentially a convertible version of its already released GranTurismo Folgore electric car. The new EV is its third go at electrified vehicles so far, and it flew us out to Rimini, Italy, to witness the big reveal in person.

EV warranties aren’t like those for non-electric cars. Here’s what you should know
Close up of the Hybrid car electric charger station with power supply plugged into an electric car being charged.

EVs are on the rise. With awesome new models finally rolling out and charging networks rapidly expanding, it feels like we're at the tipping point of electric cars being as mainstream as non-electric vehicles. But with a whole new type of vehicle come new challenges. One challenge is adapting to charging times. Another is paying closer to attention to range. And another, as some drivers are finding out, has to do with electric car warranties.

Turns out, the warranty that comes with electric cars isn't necessarily quite the same as the one that you might get with your non-electric car. If you really think about it, that's probably not all that surprising -- after all, while they can look the same, electric cars have a completely different makeup under the hood compared to their gas-powered cousins. But understanding an EV warranty could be the difference between winding up having to pay thousands for a battery replacement, or getting one repaired on the house.
It's not all new
Before diving into things like battery warranties, it's worth doing a quick primer on car warranties in general. EVs and internal combustion engine (ICE) vehicles usually come with two different warranties -- at least when they're bought new. First, there's the basic warranty (also known as bumper-to-bumper warranty), which covers every part of a car except for basic maintenance, usually for up to three years or 36,000 miles.
