You guys are spoiled, we are going to take delivary on our 13' 4Runner tonight and I'm leaving behind a 2005 Jeep Grand Cherokee Limited with the 5.7 Hemi. The power was awesome but averaging 12.2-12.9 mpg in the city was anything but awesome. This is on stock wheels and tires... If I had a lift and bigger tires I couldn't imagine how awful gas mileage would be. I was getting 18 mpg in the city while test driving the Runner.
You are taking delivery of a 2013? What are the differences between it and a 2012?
I have not heard anything definite on the differences.
Mine is an SR5 and the only changes I noticed were moving the USB to the center console in front of the shifter, and the 4x4 selector is no longer a lever but now a knob that you turn similar to the limiteds.
I get about 14.5 in the city and 17 to 18 on the highway with stock size Mud Terrain KM2's. I think the biggest issue with MPG and the 5th gen is the size of the vehicle. It is a BIG truck and I think the engine struggles at times to get it moving. Especially with any efficiency. TRD needs to get off their asses and get a supercharger into production! Then I possibly could get better mileage but won't because I will be flooring it all the time...
