Hellcat-powered, 1,000-hp Jeep Gladiator is excess fit for a Roman emperor

The Jeep Gladiator and the Hellcat V8 engine are two products from Fiat Chrysler Automobiles (FCA) guaranteed to generate buzz, so what happens when you put them together? Texas tuner Hennessey Performance stuffed a Hellcat engine into a Gladiator to create the Maximus 1000 — so named because it has 1,000 horsepower. Are you not entertained?

The Hellcat engine doesn’t make anywhere near 1,000 hp in stock form, so Hennessey treated the 6.2-liter supercharged Hemi V8 to some upgrades. The engine control unit, wiring harnesses, radiator, and fuel system were all customized, and Hennessey fitted a bespoke stainless steel exhaust system. In addition to its four-figure horsepower number, the Maximus’ V8 makes 933 pound-feet of torque. Power is channeled to all four wheels through an eight-speed automatic transmission.

Hennessey made some changes to the rest of the truck as well. It installed a 6.0-inch suspension lift kit and 20-inch BFGoodrich KD Off-Road tires. New front and rear bumpers and a smattering of LED lighting give the truck a more aggressive look. The interior gets custom leather upholstery.

Jeep actually looked at installing a Hellcat engine in the Gladiator, but encountered a problem. While the engine did fit, it didn’t leave enough clearance for crush zones, making it harder for the vehicle to absorb energy in a crash, Jeep boss Tim Kuniskis has said. He previously claimed a Hellcat-powered Gladiator would not pass federal crash tests, which is why Jeep hasn’t offered the combination from the factory. Rumor has it that Jeep will launch a sportier version of the Gladiator, but likely with a smaller engine.

Because it is modifying existing vehicles, not building them from scratch, Hennessey doesn’t have to worry about crash-test certification for its Hellcat-powered Gladiator. The company is known for crazy projects like the 1,000-hp Exorcist Chevrolet Camaro, six-wheeled pickup trucks, and the Venom F5, a supercar that Hennessey claims will top 300 mph.

Hennessey only plans to build 24 Maximus 1000 Gladiators. Putting one in your garage will cost $200,000, although Hennessey said that includes the price of a stock Jeep Gladiator base vehicle. Production starts in July, and each vehicle is expected to take about four months to build, according to Hennessey.

The Tesla Model Y is far from my favorite EV, but I’m pretty close to buying one
Tesla Model Y One Millionth Car

I may finally be on my way toward buying my first EV. Sure, I've tested dozens of electric car models over the years, but despite that (or perhaps because of it), I have yet to buy one. But my family is growing, and my wife and I aren't so sure about carting our future kids around in an aging car that lacks the safety features of modern vehicles.

Because of the fact that we're expecting our kid in January, we have a bit of a deadline. So what are we leaning toward? Well, despite the fact that it's far from my favorite EV, we may actually end up just getting a Model Y.

Ford Mustang Mach-E Rally kicks up some dirt
Ford Mustang Mach-E Rally driving on a dirt road.

The Ford Mustang Mach-E electric SUV pushed the hallowed Mustang nameplate in a different direction, and it's doing that again with a new performance variant. Debuting in 2024, the Ford Mustang Mach-E Rally is designed for fun on both pavement and dirt.

Rallying is a form of motorsport where drivers compete to set the quickest time over a course — usually a closed road or trail — rather than a dedicated racetrack that includes a variety of surfaces like dirt, gravel, or even snow. Rallying has inspired some epic performance road cars over the years, including the Subaru WRX, Mitsubishi Lancer Evolution, and Ford's own Focus RS, but it's never really been associated with the Mustang.

BMW scraps its unpopular approach to heated seats
Driver's seat and dashboard of the 2023 BMW iX M60.

BMW caused much consternation last year when it launched a subscription-only option for heated car seats.

The idea of having to pay a monthly fee of $18 to keep your posterior warm during the winter months still seems as absurd as ever, but the good news is that the German automaker has now decided to scrap the fee. What particularly irked customers was that they felt they were being forced to cough up extra for functions that would previously have been expected as standard. The fiasco even prompted a community of hackers to offer their services to unlock the feature for those unwilling to pay extra for it.
