End of the Line: Chrysler's 3.7-Liter V-6 in Jeep Liberty, Ram 1500, Stops Production

Chrysler's aging 3.7-liter V-6 is no more, reports Automotive News. Currently found under the hoods of the not-long-for-this-world Jeep Liberty, and the pre-refresh 2012 Ram 1500, the engine will go out of production by fall.

Next month, production also ends for the current Jeep Liberty, which has been in production with no significant changes for years. A new Jeep Liberty riding on the Alfa-Romeo-derived CUSW chassis (the same one underpinning the 2013 Dodge Dart) is set to debut next year as a 2014 model. Unlike the current Liberty, the 2014 model will likely be powered by turbocharged I-4s and possibly a downsized 3.2-liter Pentastar V-6.

With the 2013 Ram 1500 finally getting the new 3.6-liter Pentastar V-6 and the current Liberty going out of production, Chrysler no longer has a use for the 3.7-liter V-6 and will end production of the engine in September. The Mack II engine plant in Detroit where the 3.7-liter V-6 is built will be idled, and employees will work at other nearby Chrysler plants.

The outgoing iron-block 3.7-liter V-6 produced between 210 and 215 hp and 235 lb-ft of torque under the hood of the Liberty and Ram 1500. The new 3.6-liter Pentastar V-6 is more efficient, while producing about 280 hp and 260 lb-ft of torque in its least potent form.

I am from Australia. So when will the new Jeep Liberty have the new pentastar engne? Are there any release dates yet from the US? I dont want to buy a Liberty now and find out that they are getting a new engine in a few months time.

The 3.7L V-6 was never in the Jeep Wrangler or a front wheel drive application such as the Grand Caravan. Being a 90 degree V-6, it was to wide of an engine for these applications. It was the 60 degree 3.8L V-6 that was found in the Wrangler & Caravan vehicles. Please learn to get your history and stories straight before reporting information such as this.

I am ex Chrysler tech. The 3.7 was not in the wranglers or the vans.. They both had 3.8 v6's the 3.3 was also available in the van. Get your facts correct.

Too bad the 3.6 couldn't be available in the Liberty. Would cure the lack of highway hill pulling ability. Correction: the 3.7 was NEVER available in the Wrangler or Grand Caravan (or Chrysler Town and Country). It was the push rod 3.8 liter.
