I was lucky enough to score the keys to a 2012 Jeep Wrangler Unlimited Sahara to take home one night last week and I loved it.
While I haven't driven a JK with the old 3.8-liter V-6, I can't imagine it being anywhere near as good as this new 3.6-liter Pentastar V-6. Simply put, the Pentastar is fantastic in the Wrangler Unlimited. Its got plenty of power and the new five-speed auto shifts smartly from gear to gear. The great thing about the Pentastar is that the Wrangler now has the cojones to match up with the looks. I used to be a firm believer of dropping a Hemi in the Wrangler and calling it a day, but no more -- the Wrangler Unlimited doesn't need it. It's finally perfect just the way it is.
