Chrysler News: Rumorpile: Updates Incoming For Pentastar V6s

Recommended Posts

With stricter CAFE standards just around the corner, Chrysler is looking at giving their Pentastar V6 range some big changes.

Automotive News has learned from sources about a new plan called Pentastar Upgrade - or PUG. PUG will feature such improvements as direct injection, turbocharging, and other technologies to bring more power and better fuel economy. Fiat's MultiAir variable valve timing technology will remain.

Now the first of these updated engines could arrive in the 2015 Grand Cherokee in the guise of a 3.6L V6. This will be followed by a updated 3.2L V6 in the 2016 Town & Country minivan.

The pentastar today is very efficient. Direct injection will make it more so.

With turbos, we're probably looking at a base Hemi replacement.

Yet DI on Pushrod engines from GM seem to do the same thing compared to turbo. I wonder if this marketing push is really just that, no real benefit but increase in cost due to complexity.

Remember, Jeep is trying to make big inroads in Europe and China. This move is probably linked to that.

will the power difference be substantial? i looked for the 2015 grand Cherokee, i didn't notice it being outside of ~5 hp?

      When we drove the Mazda CX-5 towards the end of last year, we found ourselves wishing that either the long-delayed turbodiesel or possibly the 2.5: turbo-four from the CX-9 would grace the engine. The 2.5L four-cylinder does ok around town, but really struggles when more speed is needed. It seems our wish could be coming true.
      The Truth About Cars obtained a certification document from the California Air Resources Board for the turbocharged 2.5L four-cylinder. In the document, it lists the 2019 CX-9 and CX-5 offering this engine. It would give the CX-5 a nice power boost as the turbo-four produces 227 horsepower (250 horsepower on premium fuel) and 310 pound-feet of torque.
      Mazda declined to comment when asked about the document.
      We're guessing that Mazda could debut the turbo engine in the CX-5 at the LA Auto Show in November.

      Lincoln has been slowing transitioning their nomenclature system from three letter (MK_) to actual names - MKX to Nautilus for example. The next-generation MKC, due in 2020 as a 2021 model will see its name change to Corsair.
      Automotive News reports the name was announced last month to Ford and Lincoln dealers at a conference held in Orlando according to those who attended the meeting. Corsair, the name of a pirate ship and a World War II fighter plane first came to light last year when Ford filed a trademark on. The name was last used on a badge engineered model between Ford and Nissan for Australia.
      Sources at Ford said the name isn't final and could change before the model goes into production.
      Dealers at the meeting were also shown the next-generation Ford Escape, Explorer, Mach 1 EV crossover, and the Lincoln Continental with suicide doors.
