New guy here...
Hoping to give my .02 in case someone is considering the 3.0. And it’s also for the guy who is believing all the negative BS reviews like I almost did.
Long post, sorry.
Just picked up a Silverado LTZ CC Z-71 with the 3.0, two days later loaded up the family and a week’s worth of stuff for our annual trip from FL to the mountains in TN. ~ 1200 miles round trip.
Beside road trips, my commute is 80 miles round trip on rural 2-lane roads (60-70mph) and I think it’s gonna shine there. I rarely tow, and when I do it’s a utility trailer that didn’t much stress our wheezy Acadia let alone a 1/2-ton.
We got the 3.0 for fuel economy vs. the 6.2 (another great motor) and I think it delivered (averaged 24.8 mpg round trip, including a week of driving up and down the mountain on a narrow, steep road — 2500 rpms at 20 mph). On the interstate, I kept up with the flow of traffic in the left lane, if you catch my drift — no hypermiling. Truck has less than 1300 miles on it now, we’ll see if the mpg gets even better later. Mine’s 4x4, but it was in 2wd the whole time.
The truck rode and handled damn well. It is smooth and solid-feeling. Had no issues tracking straight and handling the mountains on I-40 sandwiched between a half-asleep trucker in the right lane and a cement divider wall on the left, for example.
My wife and my 3- and 5-year old kids were never jostled by any bumps or drama. Never sloppy. Loaded or unloaded. Never drove a 2019, so can’t comment if that’s different.
(To understand my POV, our other family car is a leased 2019 top-tier European SUV, which is a great car, but the only thing that it does better is superior interior materials/seats and impressing the college kid working as a valet — maybe better crash scores — otherwise, it’s a bit noisier/thirstier/harsher-riding, with coarser sounds coming from the engine bay).
Who knows about long-term reliability on a new motor from ANY OEM (so far, I’ve had great luck with GM) but that 3.0 is definitely a premium motor and works flawlessly with the 10-speed (or vice versa). The truck was never in the wrong gear, never hunting/never harsh, and always gave me the power I needed, when I needed it. No drama, just quiet supreme confidence. Kudos to the GM engineers on this one. They knocked this powertrain tune out of the park (they’ve had some MAJOR tuning missteps lately, including the 17 Acadia this truck replaced for us).
In FL, diesel costs more than 87 but about on par with 93 — I’m used to putting premium in my wife’s SUV and my G8, so that’s not a big shocker for my budget. Others without that same prior experience might feel differently.
Hope this helps someone looking at these trucks.
