End of an Era: Iconic Stellantis Engines Getting Axed

Look, most people couldn't care less what's lurking under their hood. Gas pedal goes down, car goes forward—mission accomplished. But tell a gearhead that their favorite engine is getting discontinued and you'll witness a grown adult have what basically amounts to a breakdown in a parking lot.

That's exactly what's happening with Stellantis right now. This massive car company (think Dodge, Jeep, Ram, plus a bunch of European brands) has been swinging the axe at some seriously beloved engines. And honestly? It's brutal to watch.

RIP to the HEMI V8 (Well, Most of Them)

The HEMI V8 is like the golden retriever of American muscle cars—everyone loves it. These things turned boring family haulers into absolute weapons. Picture a soccer mom's Grand Cherokee suddenly making 707 horsepower. That was the Trackhawk, and it was gloriously ridiculous.

The sound alone was worth the price of admission. That deep, throaty rumble from a 5.7-liter, or the angry supercharger whine from a Hellcat—it gave you goosebumps every single time you fired it up.

Stellantis killed most of these off in 2023 because, well, the government wasn't thrilled about their gas-guzzling ways. Now you get turbocharged engines and electric motors instead. They're probably better on paper, but paper doesn't give you chills when you turn the key.

The good news? People threw such a fit that Stellantis actually brought back the 5.7-liter for the 2026 Ram. And somehow the Hellcat is still kicking around in the Durango. Sometimes complaining loudly enough actually works.

The EcoDiesel Nobody Talks About

While everyone was obsessing over HEMI horsepower, there was this 3.0-liter diesel quietly being awesome in the background. This thing could haul a boat up a mountain pass while getting 30 mpg on the highway. Truck guys loved it because it had all the grunt they needed without the gas station visits every 200 miles.

It lived in everything from Jeep Gladiators to Ram 1500s for nearly a decade before Stellantis decided it was too much hassle to keep meeting emissions rules. Another casualty of bureaucracy.

Fancy European Stuff Gets the Boot Too

Maserati had this incredible twin-turbo V8 that was basically a Ferrari engine in a tuxedo. It made their cars sound like angry Italian opera singers and actually gave BMW something to worry about. Gone.

Alfa Romeo's twin-turbo V6 was another Ferrari collaboration that turned the Giulia and Stelvio into legitimate sports sedans. Also gone, or at least going away when they stop making those cars next year.

These weren't just engines—they were the whole reason these brands had any street cred left.

Even the Boring Stuff Isn't Safe

The Pentastar V6 was like that reliable friend who's always there when you need them. Not flashy, not particularly exciting, but it showed up every day and did the job. Stellantis hasn't officially killed it yet, but it's pretty clear they're done with it. Everything's going turbo-four or hybrid now.

Why This Actually Matters

Yeah, electric cars are faster. Turbocharged engines are more efficient. The new stuff is objectively better at almost everything measurable. But here's what the spreadsheet jockeys at Stellantis don't get—cars aren't just transportation appliances.

When you eliminate every engine with character, you're basically turning cars into washing machines with wheels. Sure, they'll get you where you're going, but they won't make you smile doing it.

The writing's on the wall though. Between government regulations and everyone rushing toward electric everything, these old-school engines were living on borrowed time anyway. Doesn't make watching them disappear any less depressing.
