New Patriot Freedom Drive II
We just bought our 5th Jeep in 14 years, a 2011 Patriot Latitude with 8,500 miles and Freedom Drive II (FDII). The MPG's so far are much better than expected. I was told to expect 19/21, but it appears to be higher as we've driven 100+ miles and the gas gauge has only moved to 3/4 full.
After having test-driven MANY Patriots with and without FDII, the FDII models are definitely quicker and have a stiffer suspension. They're most likely faster due to the lower axle gear ratios. That's also what gives them a lower MPG rating, but so far we're very pleased with both the mileage and the power.
We've owned Cherokees, a Grand Cherokee and a Liberty. The heavier suspension in the FDII Patriot makes it feel more like an older Jeep, which is kind of nice if you've had and like older Jeeps.
