Yes , it definitely feels a little slower to accelerate from a standstill than the 4.6 in the GX . Once it gets to approximately 40 mph, the 3.0 has the upper hand and it accelerates effortlessly. The GX has a good amount of torque but at 40 plus mph the 3.0’s torque advantage is apparentGood info. My wife has a 2020 GX and I wouldn’t want my Denali to be slower. Considering switching my order to a 6.2, especially since diesel here in central NC is $1.75ish more per gallon vs premium.
Honestly I was worried about the lifters in the 6.2, so I chose the 3.0 to hopefully minimize the chances of my family being stranded
