Chrysler Pentastar V-6

HI-RES GALLERY: Chrysler Pentastar V-6

Chrysler is revamping its powertrain lineup with technology the automaker claims will help contribute to an overall fuel efficiency improvement of more than 25 percent during the 2010-2014 period. In fact, by 2014, more than 80 percent of Chrysler’s current powertrain lineup will undergo a complete makeover.

One of the highlights of Chrysler's future high efficiency powertrain lineup is the all-new Pentastar V-6 engine, which officially started production this week. Soon-to-be available on certain models from the Chrysler, Ram Truck, Jeep and Dodge families, the 3.6-liter Pentastar V-6 is rated at 290 horsepower and 260 pound-feet of torque--an increase of 38 percent in horsepower and 11 percent in torque over its predecessor, plus a claimed 11 percent fuel economy improvement as well. The new mill is also fully flex-fuel ready, which means it can run on E85 fuel.

While the numbers may not appear as impressive as some competitor V-6 engines of similar displacement, or in some cases lower displacement, Chrysler will eventually add its Multiair valve technology as well as direct injection and turbocharging to boost performance further down the track.

Current highlights of the Pentastar V-6 include its double-overhead camshafts, aluminum cylinder block design and 7,200 rpm redline.

The first model to be equipped with a Pentastar V-6 will be the 2011 Jeep Grand Cherokee, which is tipped to go on sale in the second quarter of the year.

Production of the new V-6 is taking place at Chrysler’s Trenton engine plant in Michigan, which has an annual manufacturing capacity of more than 400,000 engines.

    You keep posting that on different websites. Official epa numbers arent out, but based on the 11% increase, it's safe to say it will get ATLEAST 23 mpg on the highway. The 22 mpg you speak of on the borrego is for 2wd models only. 4wd models get 20 mpg. Show me another suv with a V8 that gets 22 mpg on the highway. Highway mpg isn't the whole story either, mixed driving the borrego averages 18 mpg, and many reviews from real world driving have said that gas mileage is horrible on those SUVs. Compare it to the V6 borrego and the Pentastar V6 still beats that too.

    Highlander V6 17/23
    4Runner V6 16/20
    Xterra V6 15/20
    Murano V6 18/23
    Borrego V6 16/21
    Explorer V6 13/19
    Pathfinder V6 14/20
    This Pentastar V6 in the Grand Cerokee gets better gas mileage than a lot of those V6s all while making the most power. So I don't get why you keep criticizing. Am I missing something?? The Borrego V8 gets 16/20 in 4wd form. It gets 22 mpg in 2wd form. The Pentastar V6 is still more efficient. But we don't know the final numbers yet, so why criticize?

    Glad it is getting Multiair from Fiat, it is a great technology and I am impressed to see that the power is up to 290, because originally it was supposed to be 280.

    I was curious as to why there is no mention of the FIAT transfer of technology to Chrysler in this and related Pentastar articles. FIAT have a long history of powertrain innovation. Their innovative diesel common rail technology was thoughtlessly handed over to the Germans in the 1990s. Doh.
    At least this time they will hopefully profit from the sharing. Chrysler wouldn't have come up with anything like Multiair on their own - seems unfair not to give FIAT due credit.
