The 2010 Jeep Grand Cherokee was the first home for Chrysler's Pentastar V6 engine. As you may recall, the powerplant was codenamed "Phoenix," and it was charged with replacing seven other engines in 11 models in the Chrysler and Dodge lineups. Along with it being a well-regarded piece of engineering, its sheer ubiquity goes a long way toward explaining how in just 18 months the Trenton, Michigan plant that produces it has cranked out a million of them.
The 3.6-liter V6 is rated from 283 horsepower up to 305 hp, and can be found under the hood of front-, rear- and four-wheel drive vehicles in varying transmissions. Another signal of how much Chrysler thinks of the Pentastar: after being finagled into the 2012 Jeep Wrangler, rumors last year suggested a twin-turbo version of it could go into the Maserati GranTurismo.

One Millionth Chrysler Pentastar V-6 Engine Produced at Trenton Engine

- State-of-the-art Chrysler V-6 engine reaches milestone in just 18 months
- Pentastar engine now offered across 11 Chrysler Group models
- Truly diversified engine is available in front-, rear-, and all-wheel drive models including new Chrysler 300 and Dodge Charger with eight-speed transmission


AUBURN HILLS, Mich., Jan. 27, 2012 /PRNewswire/ -- Just 18 months following the start of production as the standard engine for the 2010 Jeep® Grand Cherokee, the one millionth Pentastar V-6 engine was assembled today at the Chrysler Group's Trenton (Mich.) Engine Assembly Plant.

"The Pentastar engine is a cornerstone of Chrysler Group's effort to reinvent its business model with world class quality products. This award-winning engine is proof that the Company is transforming its products to meet the needs of our customers," said Brian Harlow, Vice President, Head of Powertrain Manufacturing, Chrysler Group LLC. "To build one million of anything, and in an impressively short amount of time, is a significant achievement. But to do it with such a high degree of quality is a testament to our skilled and dedicated workforce at both Trenton South and Saltillo engine plants."

The 60-degree, V-6 engine, the most advanced six-cylinder ever produced by Chrysler, is now available in 11 vehicles across the Chrysler, Dodge and Jeep® lineup and available in front-, rear-, and all-wheel-drive configurations. Depending on the vehicle, engines are tuned for specific applications with horsepower ranging from 283 on front-wheel-drive models and up to 305 horsepower on the sporty Dodge Challenger. The all-aluminum engine is standard or available on the Chrysler, 200, 300 and Town and Country; Dodge Avenger, Challenger, Charger, Durango, Journey and Caravan.

For 2012, the 3.6-liter engine also is standard with Jeep® Wrangler and provides 285 horsepower – an increase of 40 percent over last year's model. Torque is up 10 percent to 260 lb. ft. and highway fuel efficiency is improved to 21 miles per gallon (mpg) on the 2012 model.

Engineered to meet a variety of requirements, the Pentastar V-6 engine also is the exclusive engine used with the new eight-speed automatic transmission on the Dodge Charger and Chrysler 300 models. The new engine and transmission combination deliver 31 mpg on the highway.

Just recently, the Pentastar V-6 repeated as one of the "10 Best Engines" following evaluation and testing by editors of Ward's Automotive magazine.

Despite the impressive gains in power, the engine is designed to run on regular 87 octane gasoline. It also is capable of running on alternate fuels including E85.

Designed for the future
Since its introduction, the new engine has replaced six legacy V-6 engines ranging from 2.7-liter up to 4.0-liters in the Chrysler Group LLC product portfolio. Overall, the new Pentastar has enabled Chrysler's Powertrain organization to reduce major engine components from 189 parts to just 32, greatly simplifying the build process and improving quality.

Some parts, including exhaust manifolds, have completely disappeared by virtue of being cast directly into the cylinder head. Previously, 32 different exhaust manifolds were used on a variety of V-6 engines. Upper- and lower- intake assemblies, which accounted for 21 and 11 different part numbers (respectively), have been reduced to two upper and two lower assemblies.

Camshaft variations have dropped from 14 to four and just two fuel-rail assemblies are now required rather than the previous 14.

Weight reductions are equally impressive. Fully dressed, the new Pentastar V-6 is 94 pounds lighter than the 3.7-liter engine it replaced on the Jeep Grand Cherokee. Similarly, while larger in displacement, the Pentastar is 42 pounds lighter than the 3.5-liter it replaced in the Chrysler 300.

The engine also is extremely efficient with advanced emission technology.

The V-6 requires no Exhaust Gas Recirculation (EGR) which helps reduce the mass and complexity of the engine. The engine meets Federal Tier 2 BIN 5 emission requirements and Ultra-low Emissions Vehicle II (ULEV II) standards, and was designed to meet all known future worldwide standards including LEV III and PZEV Californian standards. For export, the engine is capable of meeting Euro6 emission standards.

In addition to Trenton South, the Pentastar V-6 also is produced in Saltillo, Mexico.

More than 1,300 workers are employed at the two engine assembly plants with two shifts at each location. The Trenton Engine Plant, one of Chrysler group's most modern plants, was the first engine manufacturing facility to receive the U.S. Green Building Council LEED Gold Certificate for environmental excellence in building design.

      This engine alone has earned Chrysler loads of respect IMHO...Every car, truck, van, SUV, CUV, Jeep they put it in is at least respectable in the engine department which makes up for about 50-70% of my respectometer.

      I had heard as well that Daimler is using the basics of this engine to replace their current sixes. Of course magazines will never mention this. At any rate, congratulations Chrysler!

      If FIAT can help Chrysler produce, refine, upgrade their products, AND keep people employed, then I am all for it. After all, quality, not quantity, sells.

      Originally this engine was going to be used for Mercedes vehicles as well. Do they build a version of it?

      I have one in my '12 Challenger and I'm very happy with it. Good gas mileage and good performance for a V6. 305hp is no small engine...

      I rented a Dodge Grand Caravan with this new V6 engine 2 weeks ago. All I can say is WOW, I only used 13 gallons of gas from Los Angeles to San Francisco doing 75-80 mph on the freeway with three other people and their bags. Love this engine because the power is there when you need it especially on mountain passes. It is so smooth. I've driven a Honda all my life and now I am actually looking at Jeep/Dodge/Chrysler cars with this engine for my next purchase.

      I'm confused... I highly doubt Chrysler has sold over one million cars in 18th months, so how could they have built that many engines...?

        Actually Chrysler has sold well over a million cars in 18 months. If you are paying attention you would know this is the hottest V6 in the marketplace and Chrysler would have sold even more cars if they had more of these great engines. I'm sure Mighty Mopar will stay ahead of whatever fading Honda has for V6's.
        Flash!

        Chrysler sold more than 1.3 million cars in 2011, so when you look at cars sold in the last 18 months plus current dealer inventory, it's easy to see how they made 1 million of this engine. Kudos to Chrysler. It really is a terrific engine, too. The new 2012 Wrangler is superb.

        Chrysler sold 1,369,411 vehicles in 2011 smart @$$. Does your foot taste good?

          methos1999, Don't sweat it. The problem is, that Chrysler has gotten so much bad press and has been bashed by so many here (not all, and there are plenty who like and support Chrysler here as well) that for someone like yourself who may not be familiar with the market numbers would think that Chrysler is hardly selling anything. The fact is they are selling over a million vehicles every year. When the economy was good they sold over 2 million. They are usually only outsold by Toyota, Ford, GM, and Honda. There is a chance that Hyundai may pass them (and a others too) in the future but all the good product from Chrysler lately means it won't be a given. Honda may continue to fall if it doesn't get it's act together. Interesting times.

          Guys, settle down (or take your meds) - I wasn't trying to be a smart @$$. I didn't have any numbers, but given they sold ~1.3 million cars, and not all of them have this engine, I was surprised that they would have built so many...

          @methos1999 - You have to take some comments with a grain of salt or just ignore them, hehe. You're question was totally legit, I was a little surprised myself when I read the numbers. Don't let just a few put you off having some great conversations about car stuff here - most of us are nice. :)

        The Pentastar is still a baby in it's development lifecycle. There are all sorts of options for Chrysler that have been talked about at Allpar.com. DI, twin turbo, super charged, and Multi air. Also a possibility are different displacements for 3.0 to 4. something. What you see now is not all that there will be.

        People will still buy the pentastar instead, because all of honda's vehicles look like quasimoto.

        But the engine will come inside a honda. That is NOT appealing to enthusiasts, just fanboys.

        • 2 Years Ago
        Upcoming? GM's 3.6L DI already makes up to 323 hp and that version of the engine has been out for more than a year. Honda lagging behind again :|

      I love this engine! I've had some seat time behind it in a couple of different rides, and it's really good - like really really good. It is a bit of a bummer it's tuned so heavily towards economy though. I'm convinced it has a lot more to offer down low than what they let it put out, but if you get it up into the power band it'll move a 4000+ lb car with respectable authority. I'd love to see this engine in a small two door coupe with RWD and a stick!

      This engine debuted in the 2011 Grand Cherokee, NOT the 2010.
