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

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…

Mercedes-Benz G580 first drive: old-school off-roader goes electric
2025 Mercedes-Benz G580 from three quarter view.

American car buyers mostly know Mercedes-Benz as a luxury brand. But for decades, the automaker has also produced the tough, rugged G-Class (also known as the Geländewagen or G-Wagen), an SUV not afraid to get its leather upholstery muddy. And now, this iconic Mercedes is going electric.

The 2025 Mercedes-Benz G580 with EQ Technology — the final name of the SUV previously known as the EQG — isn’t the first electric off-roader. The Rivian R1S and R1T and GMC Hummer EV have proven that electric powertrains and off-roading are a great combination. But the electric G-Wagen is different because it’s based on an internal-combustion model — and a very traditional one at that.

Honda believes hydrogen semi trucks will make the case for fuel cells
Honda hydrogen fuel-cell semi truck.

Honda remains committed to hydrogen fuel-cell vehicles, but the market for those vehicles remains limited. So Honda is looking at other uses for fuel cells -- including commercial trucks.

To show how that could work, Honda converted a semi truck to fuel-cell power, replacing its diesel engine with three fuel-cell modules. Together, the three modules produce a combined 321 horsepower, and can propel the truck to a top speed of 70 mph. There's enough onboard hydrogen storage capacity for a 400-mile range with a full load, Honda claims.

Mercedes-Benz G580 vs Rivian R2: Is the much cheaper Rivian actually better?
2025 Mercedes-Benz G580 from three quarter view.

Mercedes-Benz has finally taken the wraps off of the new "Mercedes-Benz G580 with EQ Technology." Yeah, it's a mouthful, but it's basically a new electric G-Wagon. It looks a lot like the G-Wagon you know and love, but with an electric powertrain and a battery. It's not the only electric SUV out there, however, and there are some great ones -- like the Rivian R2.

Both the Mercedes G580 and the Rivian R2 have a lot going for them, but they also approach the electric SUV slightly differently. Is one better than the other? I put the two head-to-head to find out.

The approach that the two vehicles take to design is quite different -- and you might like one better than the other.
