Hellcat engine fits in the Jeep Gladiator and Wrangler, but there’s an issue

The 6.2-liter supercharged Hellcat V8 engine has been a fountain of youth for the Dodge Challenger and Charger, and has also livened up the Jeep Grand Cherokee. Jeep has now confirmed that the engine also fits in the Wrangler and Gladiator, but a major problem prevents it from being used in those vehicles.

Jeep boss Tim Kuniskis told Australian car website Drive that the Hellcat “fits like a glove” in the Wrangler and its Gladiator pickup truck sibling. But the fit is so tight, Kuniskis said, that it leaves no “air space” between the engine and the body for crush zones, making it harder for the vehicle to absorb energy in a crash. A Hellcat-engined Wrangler or Gladiator would not pass federal crash tests, Kuniskis said, nixing the idea of offering that setup from the factory.

For now, the most powerful engine available in the Wrangler and Gladiator will remain the 3.6-liter Pentastar V6, which makes 285 horsepower and 260 pound-feet of torque. The Wrangler is also available with a 2.0-liter turbocharged four-cylinder engine, good for 270 hp and 295 lb.-ft. Jeep will add a 3.0-liter turbodiesel V6 option for the Gladiator in 2020. That engine will make 260 hp and 442 lb.-ft.

Hot-rodders may very well rip those engines out of Wranglers and Gladiators and replace them with Hellcats. It’s also possible that Jeep will offer a performance version of the Gladiator — without the Hellcat engine. Motor Authority reports that Jeep has dropped hints about such a model, nicknamed Hercules. It would make a perfect rival to the Chevrolet Colorado ZR2, which makes due with gasoline V6 and turbodiesel inline-four power.

Jeep may also take the newly launched Gladiator in other directions. The automaker recently unveiled six Gladiator-based concept vehicles for the annual Moab Easter Jeep Safari. One, the J6, is a two-door version of the truck. While most rivals offer more than one cab style for their midsize trucks, the Gladiator is currently available only as a four-door. Jeep boss Kuniskis told Australia’s Drive that Jeep is “gauging interest” in a production version of the J6, while also noting that four-door models make up most of the sales in the midsize-truck segment.

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.
