LZ0 Duramax Decision - Input Requested

[StephenPT]

I appreciate everybody's input, lots of good info. On the dealer warranty - I understand the potential gotcha's there. I'm not seriously considering it just because of the fuel economy of the 6.2L, but if I did I'd comb every line in the document. I'm that guy that annoys the sales/finance team because I actually read what I sign.

One other question, regarding regen. Since this thing would be used by the wife for a lot of short (5-15) minute trips around town, am I going to potentially run into issues with the regen process? I hear people say to just drive it like a gasser but I'm not sure if that's actually the case.

A full regen process takes ~12min. I have a Banks IDash installed to know when it's doing a regen in addition to watching other things like oil temp, boost psi, etc. While we mainly use ours for long family trips and it rarely does short in-town trips, there's been a few times where it wants to regen, but we need to turn it off and then the next trip is a short trip to town. The system is designed to regen as much as possible each drive to lower the soot load and get it down to ~0%. If there's too many short trips and it's not making much progress on the soot load with each trip, you'll get a notification to "continue driving to clean exhaust system." I've never had that happen personally, but I've seen others have received that message.

Back in December I bought a 2025 AT4 Ult with the 6.2. Love the car no issues at all except the range was awful. With only a 24 gal tank, I was averaging ~350 miles between fill-up's. When towing boat or trailer, would only get ~220 miles on a tank.

I just traded in for the exact same car, but with the LZ0. Taking delivery Saturday.

I am doing the exact same thing. I have a 25 Denali Ultimate with the 6.2. I wanted the Duramax all along but needed a vehicle so I took the plunge. Love the car, and the throaty sound of the 6.2, but regret not getting the Duramax. I placed an order for the exact same vehicle with the Duramax but we'll see how much the dealer works with me on the swap. How did your negotiation go on this?

I bought my LZ0 off the lot. They had 3 ready to go. Traded my 6.2 AT4 Ultimate with 13,000 miles for 87,500 and got the 3.0 AT4 Ultimate for 94,700. Me and the salesman compared the pricing sheet, same options and everything, just different motor. MSRP has gone up $500 since Dec '24

$7,000 delta? I think you got a screaming deal. I did the same thing on a Highlander. 2024 6.2 for a 2025 3.0, identically optioned out, I didn’t even come close. Maybe this whole 6.2 thing is a conspiracy to sell some 3.0s.

The baby max is cooler than sheeeet. Now I call it a truck not a suv. Flame away.

24 mpg at 80mph cruise (through some large hills/passes as well) @ 1,700rpm in the LM2 yesterday. 160 mile trip. 2024 Yukon XL SLT. My buddy tells me he can’t get that in his Honda CR-V.

This thing is a highway torque machine.

We bought a 2023 Lexus Rx350L new cause we loved the quiet and luxury comfy ride. After 2 yrs just got tired of the small low ride. Ordered the 25 denali yukon with the 3.0 in Feb. and got it in march. Hands down this is the most comfortable riding, way better than Lexus just as quiet and 25+ mpg, oh and all this room. Cant wait to go somewhere everyday.

Just drove another 100 miles today with my new 2025 Yukon Elevation LZ0 and got 30.4 mpg driving 65-70! Only have 900 miles on it now and will be towing with it soon.
