This is my only complaint. My 2024 Yukon XL diesel is sluggish when you mash the pedal at highway speeds. It’s almost better if you keep the RPM’s mid-range.

Around town, accelerating to highway speed… lots of pep. But if you’re cruising at 60mph or a bit less on a single lane highway and you want to pass a transport truck or a couple of cars going slow so that you can do 65mph. Floor the gas pedal to pass them and you will see that it’s sluggish. myself, I would sure to have lots of space to oncoming traffic and don’t take chances until you understand how much pull you really have on the highway.

Having said that, I have no regrets. The torque is incredible and you can cruise up and down big hills on the highway at 75mph and the transmission won’t even downshift.

Again, the only point where you’ll notice the lack of horsepower is mashing the pedal at highway speed. It’s night and day different over the F150 2.7 eco boost I just traded in, and even more pronounced with the 3.5 ecoboost in my new F-150.

You sure will enjoy getting 20-27mpg day in and day out in your diesel though :).
You can thank our glorious EPA for your sluggish response when the pedal gets mashed. Too much soot will be produced (EEk!!!!), so the calibration gives power at a rate deemed "clean." My brand new 2023 F450 work truck was the same way.........utterly pathetic if you needed to pass or get out of your own way. The de-rating was clearly evident.

Look towards our northern neighbor for companies that help diesels go on a diet and regain what they should have had from the start.
