This video shows the difference. I can personally attest to the fact that the 4.0L is the better engine. I have a 2006 Wrangler Rubicon that I handed down to my son. I now drive a 2016 Wrangler Rubicon with the 3.6L Pentastar DOHC engine. This Pentastar engine has 285 hp @6400 rpm and 260-lb-ft of torque @4800 rpm.
My old TJ with the 4.0L has 190 hp @4600 rpm and 230-lb-ft of torque @3200 rpm. Both Jeeps have the same 4.10 final drive ratio.
I have driven the mountains of WV and Virginia on I-77 countless times since 2006 in my old 2006 4.0L powered Rubicon and several times in my 2016 3.6L Pentastar powered Rubicon.
There's no comparison. My old TJ can pull the hills at 70 mph with no effort at all and the cruise control will stay at 70 mph. If I have to let off the cruise control while going uphill and then accelerate to get back up to speed, the TJ does so with no effort whatsoever. Both Jeeps are 6 speed manuals btw.
My 2016 Rubicon sucks when traversing the mountains up in VA and WV. When I have it on cruise control, it can't hold 70 or 65 depending on the speed limit, while on a steep grade. It always creeps down about 5 - 8 mph depending on the length of the climb. My old TJ can hold the speed with ease.
When I have to hit the brakes going uphill due to a slower vehicle in front, therefore cutting off the cruise control, my old TJ with the weaker 4.0L was very easy to get back up to speed. My 2016 struggles horribly to get back up to the previous speed and usually can't get there until it reaches the top and starts back down the other side of the mountain.
The lesson here as far as normal off-road passenger vehicles is concerned, in my opinion of course, is that lower revving pushrod engines rule, and higher revving OHC engines suck. If you want me to prove it, take a ride with me in both Jeeps up I-77 sometime. I'll let you drive.
