Back in 2010, Chrysler revealed its Pentastar 3.6-liter V6, a wonderful, state-of-the-art naturally aspirated engine that quickly found its way under the hood of various Dodges, Jeeps and Chryslers. But that was nearly five years ago and times change, specifically fuel emissions regulations. Chrysler has just announced that beginning in 2015, a newly improved 3.6-liter V6 will debut, likely in the refreshed Jeep Grand Cherokee. How will it differ? Two ways: turbocharging and direct injection.

Now, before anyone throws a hissy fit about said turbocharging, Chrysler was also quick to point out that its 3.2-liter V6, found in the Jeep Cherokee, will also be updated. In other words, we don't know for sure whether both V6s will be given a turbo or just one of them. If so, which? It could really go either way because, for example, the Ram 1500 also utilizes the 3.6L and it has even fiercer competition from the 2015 Ford F-150, the so-called beacon of turbocharged full-size pickups. Direct injection alone may not be enough to help the Ram 1500 achieve the needed fuel numbers. Same goes for the Grand Cherokee.
