The big Stellantis product push announced last month will transform the lineups of most of the company's 14 car and truck brands. It will also add what seems at first glance to be some serious overlap, especially between the Jeep Grand Wagoneer and Ram's soon-to-be-revealed three-row SUV.Ram CEO and driving force behind Stellantis in the US, Tim Kuniskis, explained how the Grand Wagoneer and Ramcharger would avoid driving over each other's toes. CarBuzz broke this story back in January, but Kuniskis recently shared more on the subject in a recent podcast interview with The Drive. In short, it's largely about cylinders. Ram Will Be 'V8-Focused' StellantisKuniskis said that the Jeep is going to keep its Hurricane I6 engine lineup, including both the standard output and 540-horsepower high-output versions of the engine. It will also add a V6-powered extended-range electric version later this year. Ramcharger, the pickup truck brand's first SUV, will focus on the V8 engines.The Ramcharger name was marked for the EREV version of the company's pickup, but now that is no longer the case, and Ram has plenty of V8 engines to offer. The list starts with the 395 hp 5.7-liter version and includes the 6.4-liter 392 that makes 470 hp, and the 6.2-liter supercharged Hellcat engine. The Hellcat makes between 700 and more than 1,000 horses depending on the application. Same Platform But Distinct Personalities, Similar To Large SUV from General Motors Kuniskis compared the models to competitors from GM and Ford. The former offers the Chevy Tahoe, GMC Yukon, and Cadillac Escalade, while the latter has the Ford Expedition and Lincoln Navigator. Both companies have to differentiate their mainstream and more luxury models, and do that in different ways."Our whole intent was: look at what the other guys are doing with multiple versions in different showrooms and see how much we can differentiate these two sitting next to each other so it’s not like, ‘Hey, that one’s got a Jeep badge on it and that one’s got a Ram badge on it.’ They needed to look, feel, and act different," Kuniskis said. Ram Will Be Dodge Charger To Jeep's Chrysler 300 Jeep He compared the differences to the Chrysler 300 and Dodge Charger. Both sedans shared a platform and engines, but each one had a very different style and attitude. "They were absolutely different buyers, and that’s exactly what we’re trying to do with this. We want one to be very focused on who a Ram customer is and one very focused on who a Jeep customer is," he said.To do that, the engines will play a big role. "Our intent is to leave the powertrains as is on the Jeep, as is as in the architecture. That doesn’t mean that we won’t have multiple versions, different power levels, but the architecture. And then the architecture of the Ram would be more V8-based," Kuniskis said.Jeep's Grand Wagoneer hasn't exactly been a smash sales hit. It has struggled, and recently Jeep reshuffled the entire lineup, dropping the "Wagoneer" branded models and bringing them inside the Grand Wagoneer name.This second SUV, then, is going to need to find a completely different buyer. The buyer probably won't be one looking for the lower price, either, as the Grand Wagoneer now starts for around the same mid-$60,000s price as Chevrolet and Ford, not leaving Ram much room to undercut. We'll learn more about the new SUV over the next few years. CarBuzz Insight – Why This Matters: Splitting Ram from Dodge so many years ago essentially created a car company with just two products: pickup trucks and work vans. This left Ram without one of the most popular product lines of them all: SUVs. It's imperative for Ram to have its own SUV, but it also must be uniquely Ram. Everyone remembers the mess that General Motors ran into with its badge-engineered cars through the 1980s, 1990s, and 2000s – one could argue the extensive platform sharing with generic personalities ultimately led to the demise of Oldsmobile and Pontiac.Joel Stocksdale / CarBuzz / ValnetPlugging in a completely different range of engines is a good way to separate Ram from Jeep, but Ram must go further to truly make Ramcharger its own machine. Expect a different interior to accompany Ram-specific bodywork and the V8 engine options. We look forward to finally seeing this long-awaited SUV debut, which should happen for the 2028 model year.
