I tested both the 3.7 and the 4 liter engines and found that the 4 liter was a rocketship compared to the 3.7 engine. I purchased the 4 liter. The R/T package will also get you 20 inch wheels and a sports turned suspension. The R/T version handles as well as my Audi A4 in tight corners with this package and I am amazed at the quickness of this SUV. Very little lean. Fuel economy is rated at 21 miles per gallon and with only 350 miles, I am getting 18.2mpg. The interior fits my style and is very confortable. The slide and go storage is great for anyone with a sore back getting items out of the rear end. Built in GPS, subwoofer, bluetooth and 20 gig hard drive with Ipod plug in. I am happy.
