I really don't get all the hate the 2.4l tigershark engine receives.
Coming from a 1.8l turbo hatchback, I find the tigershark more refined in terms of engine sound at high rpm, and totally adequate in terms of power even with AD1.
I have 27,000mi in a year and a half, have taken many long distance road trips, have crossed over the Sierra Nevada mountains back and forth at least 6 times and I have never had problems with the power. Yes, passing on the highway isn't as quick and painless as it was on my turbo hatch, but this is an SUV after all.
On the way to Reno, I pass most vehicles going up the mountain and never struggle maintaining 10mi above the speed limit. Safety limits me before the power of the engine.
It's true that in AUTO, the Cherokee gets sluggish because it wants to up shift as fast as possible, but if you put it in SPORT, it turns into a whole different vehicle: quick and responsive.
