The two 2005's I had were the last pickups that actually had some getup and go, I still have one of those trucks. Its loaded for bear with a heavy-duty commercial capper and full of tools. I get whip-lash every time I get in that truck.
I traded the other 2005 for a 2010 and all the trucks since have been lazy dogs. Sure they do about 1400rpm or less at 95km/hr. They switch in and out of 4 cylinder mode. When you step on the gas it spends the next second or so deciding what gear its going to change to. I can visualize the little hour-glass spinning in its control computers. Many times its feels like you are slowing rather than accelerating in that time.
When you flip the transmission into tow/haul mode, it becomes a different truck. Accelerating from stop with my utility trailer, it may wind up to over 4,000 rpm in each gear (6 of them) before shifting. Depending on the load it may not get to the top gear and the rpms will be in the 2-3000 range at highway speed. This is with a total load of maybe 7-8000lbs.
According to the trucks display. my 2005 gets about 13.2 litres/100km combined city/hyway. The 2016 and 2017 I have now get about 12.7litre/100km. I don't think the new ones will get as much life as the 2005 with all the shifting they do.
"That is what you have to expect for a new normal." - Guess who
That manufactures know all about this. They have to program the verhicles for emissions on a programed road test and CAFE. Pickups did not used to be included in CAFE. But, when the overreaching government found out that people were buying pickups because they were still fun to driver, they put an end to that as quickly as they could.
