It would be cool to offer the 4cylinder turbo in it. Makes good power and great fuel economy. Especially compared to 5.3 v8.
I haven't driven the pickup with the 4cyl, but a good friend just bought one... his mpg is no better than my '18 Yukon Denali. It has decent enough power to move an empty half ton pickup around but there's no way I would put it in a full size SUV...

The city mpg should be much better then your truck or the 5.3 currently on sale. 19/22 vs 16/21. 9500 lbs vs 11200 in towing. I think it will have plenty of get up for a suv especially because it makes more torque then the 5.3.

6.2 = 420hp 460tq
5.3= 355hp 385tq
2.7 turbo= 310hp 430tq
3.0 diesel lm2= 277hp 460tq
3.0 diesel lz0= 305hp 495tq


Should be a good option for someone that doesn't need all the towing and wants a good driver and some capability.

They can barely sell those in the pickups, why would anybody buy that over the diesel if they want good fuel economy?
It's misunderstood. Gets bad credibility because it's a 4 cylinder and the macho truck guys can't have that.

As a powerplant it's pretty sweet. And super durable too. I think it makes a lot of sense. Not to mention how much room in the engine bay there is.

You pay gas price not diesel price for one. More hp then lm2 and slightly less tq. Cheaper to maintain as well.

According to the EIA.gov website the national average regular gasoline price is 3.456 a gallon. Diesel is 4.247. So it's roughly 0.80 a gallon more for diesel.

The L3B in the 2WD Silverado 1500 is rated for 19 city, 22 highway, 20 combined mpg. The LM2 is rated for 23 city, 31 highway, 26 combined mpg in the same truck. This is off the EPA website.

So 20 mpg at 3.456 a gallon is 0.1728 a mile to drive, meanwhile 26 mpg at 4.247 a gallon is 0.1633 a mile to drive. The LM2 is cheaper per mile to drive. Especially if you do a lot of highway driving; the more highway driving the bigger the advantage goes to the diesel.

This is also keeping in mind that the silverado/sierra got better mpg results than the tahoe/yukon/burb got with the same engines. Diesels do better under load than gasoline engines do. Especially turbocharged gasoline engines. So putting the L3B in the SUVs would likely drop its mpg more than the LM2's in the SUVs dropped. The LM2 also has a significantly better warranty.

I see no world where the L3B makes sense in any platform where the LM2/LZ0 is an option. There is a reason the L3B rots on lots in the middle of a shortage. When I bought my Yukon last fall 3 different dealers I went to kept trying to sell me pickups with the L3B when I said I wanted the LM2. It was the only thing they had on the lot that wasn't selling before it even got there.

Thanks for crunching the numbers, .1 between the 2 only accounting for mileage. Diesel has higher maintenance cost. Diesel is also a higher up front cost. The 2.7 turbo would be much cheaper msrp to msrp. And gas appeals to masses more. Gas turbo also makes torque down low but better mid and top compared to diesel. So it will run well but obviously it's a trade off in capability.

I'm just saying it would be a compelling option for a lot of people in the suvs.

I agree. I rented a Sierra Elevation with the 2.7 last week and drove it several hundred miles near Lake Tahoe. I was impressed with the power - especially the low-end torque. Went the whole week, driving every day to different ski resorts, plus twice to Reno and back and never had to fill the tank until returning it to the airport, and I still had 100 miles of range left. All of the guys I was with were also impressed by it. Match it with the 10-speed and it would be a great engine for these SUVs. I pull a 7,500 lb camper with my 6.2 and I'd wager the 2.7 would do fine even with towing duty.

If I still lived in Colorado I'd buy a 2.7 in a heartbeat. The NA engines lose 3% of their power for every 1K' above sea level, but turbo engines don't.

I'd be concerned moreso with longevity and reliability when putting a 4 banger in one of these SUV's... I personally am still skeptical of them being in trucks. Sure a smaller engine gets better gas mileage, but that's when you drive it casually. Push the RPM's into a 'lively' driving range, which is incredibly easy to do in a 4cyl, so that it doesn't take forever and a day to get somewhere, and mpg's plummet.. and fast. Add considerable weight along with it, and then add a trailer on the hitch... even if a 4cyl could do it, it's going to be screaming the whole way, working much harder than any V8 would have to to accomplish the same thing. As with everything in nature, the faster the heartbeat, the shorter the lifespan. Even if you save some mpg's, gone would be the days of a 300k-400k odometer.

I was getting all excited, I thought the announcement was about GM offering to replace the 07-14 cracked dashes at no charge, because the original ones were crap !
