Pentastar V6 - One of Ward's 10 Best Engines for 2012, a photo by lee.ekstrom on Flickr.
This engine was a big part of Wrangler & Wrangler Unlimited's success this past year: 40% more horsepower, 10% more torque, and 26% faster times from 0-60 mph.
Pretty impressive. I especially like the fact that the oil change interval was changed to 8,000 miles instead of the typical 6K. That and the clever top-mounted "canister free" oil filter - no more messy oil changes.
The engine was purpose built for off-roading. The upper and lower oil pans were engineered to supply oil even when driving at steep angles. Wrangler and Wrangler Unlimited also received a higher-mounted alternator to allow for a full 30-inches of water fording capability.
