Chrysler is reportedly planning a ‘downsized’ 3.2-liter version of its award-winning 3.6-liter Pentastar V-6 engine.

The new engine is said to debut in the replacement for the Jeep Liberty next January at the 2013 Detroit Auto Show.

The information was revealed to Automotive News (subscription required) by company insiders familiar with the project as well as union official Bruce Baumhower.

Baumhower also revealed that the new engine will be matched with a nine-speed automatic supplied by Germany’s ZF. With the extra gear ratios, the smaller 3.2-liter engine is said to be comparable in performance with the current 3.6-liter Pentastar V-6.

The new engine is expected to be built at the same Trenton North Engine plant in suburban Detroit that recently built the one millionth Pentastar V-6.

The Jeep Liberty replacement, meanwhile, will be built at Chrysler’s Toledo North Assembly plant in Ohio. The plant is currently undergoing renovations to retool it for the new SUV.

Further down the track, Chrysler is expected to replace its entire six-cylinder gasoline range with Pentastar V-6 engines. Another variant with Fiat’s Multi-Air valve-adjustment technology is also planned. On top of this, there have been reports that a high-performance twin-turbocharged Pentastar V-6 is also planned and could feature in Maserati’s upcoming ‘baby’ sedan.

  1. I just hope that the next one might have aa optional engine above this one. The 3.7L in the current ('12) one is a pig. Low power, low MPG. Great if you're on the trail, maybe, but horrible for in town/highway driving.

  2. David, Do you have your engines right? The Pentastar engine is considered one of, if not the best, V-6 engines in the world. In the 2012 Chrysler 300, for example, coupled with the new 8 speed automatic, it matches the acceleration of the original 300 with the HEMI V-8 and gets 31 MPG in a big sedan. Reviewers rave over it's acceleration at speed and an almost endless flow of power. I do agree that an optional twin turbo,now in development, would be a great engine for the Maserati and other Chrysler products and the Multi-Air would be a smart addition but a pig it is not.

  3. I have to agree with Bill here. The current 3.6-liter was awarded a Wards top engine of the year and I see no reason why the 3.2 won't be just as good. And if you're looking for more power, Chrysler always has the Hemis and if this article proves right a twin-turbo Pentastar too.

    Ford already has an EcoBoost V-6 and it's only a matter of time until GM unveils its own turbo six, which I believe they are working on as well.
