More Evidence of a New Engine for Future Jeeps, Rams

more evidence of a new engine for future jeeps rams

A yet-to-be-revealed engine that’s kept the rumor mill in Mopar circles churning continues to make its possible presence known. It’s an engine supposedly tapped for a new line of Fiat Chrysler products, and might find a home in existing vehicles, too.

It’s an engine that comes to the table with (arguably) the sexiest cylinder layout on the market: six of ’em, all in a row.

We’ve discussed the existence of this engine development program before, but a not-too-recent patent uncovered by MoparInsiders sheds a bit of new light. The FCA patent isn’t for an engine; rather, it’s for an exhaust gas recirculation (EGR) system that’s mated to one. However, the engine this EGR system is shown with happens to be an inline six of the turbocharged variety. That’s the same engine type that’s kept the rumor mill alive.

Sources tell the publication that the engine, of unknown displacement(s), will offer somewhere between 360 and 525 horsepower — perfect for lugging around large vehicles with authority. Large, rear-biased vehicles. Should it arrive, its output and layout would make it an obvious choice for the Ram 1500 and a number of rear-biased SUVs, among them the upcoming Jeep Wagoneer and Grand Wagoneer. With FCA paying big bucks to offset its man-sized fuel economy footprint, a turbo six could offer meaningful MPG improvements to several popular large models.

The rumored engine is expected to utilize FCA’s upcoming E-Booster; essentially, an electrically operated turbocharger that builds up boost right from idle, eliminating turbo lag. Mild electrification is already spreading through the FCA stable via the company’s eTorque engines.

While it’s too early to declare the Pentastar V6 and Hemi V8 endangered, the patent is another hint that their presence could soon become less dominant among full-size FCA vehicles.

    Makes sense for Ram...they already design their engine compartments around the Cummins 6 and the Wrangler/Gladiator isn't shared and so it can be designed for anything.

    Given the trend of 4cyl everything having an engine that can share some engineering seems to make sense. I know at one point Pentastar was going to be a family of engines, but I guess a combination of economics and emissions killed that plan.

  • ToolGuy VW (marque not group) and Tesla very nearly switched positions on a YTD basis.
  • RHD Inexpensive gasoline appears to be a thing of the past. ILO is correct - we have enough sunlight, wind and emerging ocean wave energy to power the entire country and then some. Clean air is nice, and being free of the whims of OPEC, geopolitics and hugely profitable oil companies will do all of us a world of good.
  • Raymond Segura Can you tell me where I can get the rear bumper for 69 impala?
  • Art Vandelay some of the crazy numbers I get. Percentages look bigger with any fluctuations with low volume makes and brands leaving the market will see massive month over month changes. But what’s with Buick? I still see the occasional ad on TV and yet the drop is disproportionate even compared to all the other GM brands.
  • Master Baiter "There is no mandate for consumers to buy EVs, not in any country or state. That’s made up."Right. And you are not mandated to purchase a toilet that only uses 1.6 gallons/flush. You could choose to not have a toilet--just go in the woods, like the bears do.
