Offer the new LS7 7.0L crate motor now rated with 570 naturally aspirated HP. Put it into an SS trim!! That would be fantastic.  I'd have one on order in a heart beat. They could also put it into a Raptor fighter and not have to worry about superchargers or turbo failures. The american truck buyer has a deep passion for their trucks and offering a big 7.0L as an option, is just what some of us WANT! 

 

I've been saying this for years, GM is missing a major chance to print money with an LS7 powered Raptor fighter.

Unfortunately GM is just not an exciting or risk-taking company under the current leadership. And/or their efforts are all-in on EVs right now. Seems like they don’t really care what the traditional gear heads want.

I have a 2019 6.2 max trailer.  Traded from a 2014 5.3 z71 with a tuner on it.  Bought it to pull my rv with more authority without the bumpy ride of a 2500 when unloaded.  It pulls incredibly well.  Big differencr.  I could have never passed someone on the highway before, now i do it with ease.  The 10 speed with 6.2 is awesome.  I usually run 89 octane around town and will do 93 when towing, though i have towed with 89.  My biggest complaint is the crappy mpg when towing.  20+ unloaded all day long.  8-9 while towing seems sad tho.  But ive learned to get over it.   Mostly.  My 5.3 oddly would do 10-11 mpg when towing samw rig.

I agree with you. My older K2 5.3Ls got around 14 mpgs pulling my trailer. My 6.2L got 12mpg and now my new 6.2l and 10 spd average 10 mpgs???  It’s crazy but I’ll take the 10 speed and comfort of the new T1 over the older K2s

 

Stepdads new 5.3L and 10 speed just daily driving he averages 23-24 all day. I can’t crack above 20 mpgs with my 6.2L.  But I do love that POWER!!!

Is it possible that because the 6.2 pulls so much easier you are driving a little more spirited causing fewer MPGs?

But, but, everyone says the 6.2 gets the same MPG as the 5.3, how is that possible? Maybe a larger displacement engine really does need more fuel than a smaller one? Who'd a thunk that?

Print money huh? You do realize the sales numbers are pretty low for the Raptor and even more so the TRX. Ford doesn't break out sales numbers but the general consensus seems to be less than 10% and somewhere around 50k in sales a year. Considering the development costs and everything that goes in to it (including warranty for added abuse) that isn't exactly printing money with all the Raptor specific items on it they have to engineer (fenders, chassis, suspension, interior decor/easter eggs, etc). GM did it right by not making a direct competitor for a smaller market that is already saturated. The desert running crowd is much smaller than the back country/overlanding market which is what the ZR2 is best suited for and going after. Kind of a jack of all trades truck, it can run the desert better than a stock truck with longer wheel travel yet do truck duties better and remain smaller for the back country truck guys than either of the wide body soft sprung Raptor/TRX.

 

They will sell more ZR2's than Raptors as a percentage. Shoot didn't they say the Trail Boss is like a 30% take rate in the video? If they keep the price reasonable they can see 15-20% I bet with this truck. It is already fully loaded so if the price is around 65k (where the Raptor starts with out the 801A luxury group and other options taking it north of 80k and TRX starts at 70k and quickly goes over 80k adding the luxury packages and other options) it should do well for GM and the truck won't be so one sided in terms of what it is set to do (jack of all trades master of none type of thing). Even the Colorado ZR2 was deemed the better all around off roader in a comparison test against the Raptor and Power Wagon, it did what the others did nearly as well and didn't struggle where the others struggle where they were out of their elements in.

The Raptor has outsold the Corvette every year since 2009. Yet, it's still profitable for GM to build those on a bespoke chassis in their own assembly plant, probably sharing the least with the rest of the fleet out of anything. So, you'd figure tweaking a platform they sell almost 1M a year to be a bit better off road and sharing a ton of parts with that same vehicle shouldn't break the bank. 

 

I'm not saying the ZR2 is a bad truck. It looks great and is a solid competitor to the Tremor, Rebel, and TRD Pro. However, it's still not at the level of the Raptor or TRX. There is room in the market for a ZR8 or whatever you want to call a top end halo truck with an LS7. It would get people into the show rooms, if price was a bit out of their budget, they'd go home with a ZR2 or Trail Boss. That's how halo vehicles work.

People spend big money driving the number 3 in performance trucks. Why change? With the new Toyota coming out it could be number 4.


yeah I been hearing the Tundra could have ECOboost figured like around 400+ hp and 500+ Lb of torque with their new TT V6 hybrid setup. Still interesting GM has not said anything about the 5.3L? Or did they ? I’m having a hard time believing their new 2.7 Base motor would have more torque then the 5.3 V8. Maybe the 5.3 got new updated ?

I owned one of those 5.3s in 2014 in a GMC. I had the E-85 option. My Texas Edition came with the 345 posi rear. With a tune I stayed with a friends 6.2. Denali. GM could easily have a nice SS 6.2 in an low option truck, even a single cab. Even if they did that I have no interest in any type of cylinder deactivation. I would be more interested in a blown 4 or 6. At least if you were easy on those your less likely to have a failure. Than waiting for a lifter to fail with cylinder deactivation. Too much going on with them for my comfort.

Negative, power ratings are all carryover except the 2.7. Towards the bottom it gives the engine details.

My older K2 GM trucks one with a 6.2L and the other 2 with 5.3L got  virtually same MPGs when driving down highway. I’d say 6.2L got overall better after tune put in it and got rid of AFM. The 5.3L with 3.42 rear ended compared to my 6.2L with 3.23 got 1 mpg better towing my boat. 
 

as for the T1 trucks. My 6.2L can’t scratch the 23-24mpgs I saw with my 2018 Sierra 6.2L. My stepdads T1 Sierra SLT 5.3L/10spd averages what my older 6.2L averaged. 
 

I have heard from Many others that the larger 6.2L gets as good as their buddies 5.3L. It’s how you drive it and I like to have my foot in the pedal of this T1 ALOT!  Especially with the Corsa Exhaust and S&B intake. 
 

your argument about engine displacement size is funny because Furds junk ecobust is 3.5L and I’ve seen first hand they don’t get the mpgs that either GM V8 gets. And they are larger in displacement. So what’s your argument going to be then?? Well, well, it has twin turbos?  🤔🤔

 

 

and don’t kid yourself on your sales numbers and profit of the Raptor. Ford makes a ton of money on their Raptors. If they didn’t they wouldn’t be in their 3rd generation of it. As for the TRX, it just came out last year. The profits will be coming. I’ve seen a plethora of them on the road. GM screwed up not offering a supercharged truck on this reveal. The regular Trailboss should have been what ZR2 is now, and the ZR2 should have been supercharged and a direct competitor to the other 2 trucks mentioned.  And they could have brought back an SS sport truck lowered, supercharged, magnetic air ride, paddle shifting, 10 spd rocking machine and got a hold of a market that is greatly being missed, because I for one can’t stand jacked up stupid looking off-road trucks that 90% of them will NEVER be used what their intended purposes were built for! To each their own.

Just under 15,000 TRXs produced for 2021. Of them, 2,000 are Level 1 that start in the mid 70s. And 12,000 are Level 2 which starts in the 80s and most are closer to 90. That’s a ton of $$$. Plus it’s a halo truck to get lots of press coverage, dealer traffic, etc.

 

All GM would have to do is build a nice supercharged street truck. Wouldn’t cost much to develop and people would be lined up out the door. Me included.
