While I agree with you, peak HP and torque are fair indicators of performance. For example, look at the RAM 3.0L EcoDiesel pickup truck. It produces 240HP and 420lb-ft. Well, the 420lb-ft is more than the 5.7L Hemi, and it produces good torque across the range. But it is SLOW. Slower than even the Pentastar V6 truck. So even if it does some things well, like tugging a load, customers are used to modern pickups as being pretty quick. And while 0-60 in 6.8 seconds is pretty good, the Ford 2.7L is a second quicker which is significant.

I guess for the people who race their trucks that one second is a lot. I don't race my truck, and I don't think a lot of people race their trucks either. Most truck buyers are brand loyal, I know I am and I know I'm not alone. My 2017 Silverado with the 4.3L isn't the fastest truck out there and I'm okay with it, because you know what....I love my truck. It has more than enough power for an entry level truck and I imagine most people who buy an entry level truck know exactly what they are getting. They know they aren't getting the fastest truck out there and you know what, they don't care. They care that it fits their needs, has the options that they feel are important to them and it gets them from point a to point b in the safest and most reliable way possible.

I don't think people are looking at only "peak" numbers. The Ford 2.7L far surpasses the GM 2.7L in Torque and HP at every RPM! On top of that it delivers better fuel efficiency as well. How is the new GM 2.7L not a total disappointment?

I've yet to see the HP and Torque graphs, so if you have them, please post them when you get a chance.

The real comparison should be with the 4.3L as the new 2.7L is the replacement for that engine. It has more power and more torque in a truck that is 380 lighter. The whole idea of a new truck design it to make it better, better handling, more efficient, etc...and in that sense...I don't see how the 2.7L is a disappointment as it is better than the 4.3L that it replaces.

Except that you're overlooking that the "old" 4.3 will also make its way into the new lighter weight truck. Despite being hampered by only getting the old 6 speed auto it still achieves better highway fuel economy than the brand spankin' new, super high tech, highly complex and expensive to produce Turbo 4 that gets the new 8 speed auto. Often the simpler mousetrap is the best long term solution.

That said, I agree that more optional drive train choices is best for the consumer. To each his own.

Following our report yesterday on the new GM 2.7-Liter turbocharged gasoline engine, Mike Ofiara from Chevrolet Communications confirmed to GM-Trucks.com that GM will recommend Regular Unleaded fuel for the engine. This will have a major impact on the fuel economy of the vehicle. Many automakers launch new boosted engines with high compression as replacements for larger normally aspirated engines, only to then require premium fuel. Premium fuel has an average cost 16% higher than regular unleaded fuel according to today's average prices. While this may not seem like a big deal at first, do the math on a typical truck with a base engine and you will find the 10-year fuel cost can be around $23,000. 16% of that is around $3,700.

With the new gasoline engine rated for the least expensive fuel in America, the cost comparison to operating a comparable diesel may tip in favor of the new gasoline engine from GM.

The EPA has yet to publish the final official fuel economy numbers for the Silverado 1500 with the new 2.7-Liter engine. Once they are available, we will post them.

That torque curve...if you can call it a curve, is pretty impressive. That's better than previous Gen IV 4.8L & 5.3L LS engines.

Well, I don't "race" my truck but there are times when I'm at a stop light and enjoy a quick drag race. I think most people do, unless they drive something really slow. I'm not putting down the 4.3L in any way - I really think its a great base engine and probably the best base engine of any full size truck by a decent margin. The problem lies when an engine does not meet expectations, which I think this 2.7L does not.

There's no way around this fact: GM developed a 2.7L turbo motor which costs nearly the same as Ford's 2.7L motor but isn't as good.

So it seems silly to buy something that is inferior to the competition. Now maybe you can justify that the GM truck is better than the Ford truck so you'll accept the inferior engine, but that's where brand loyalty comes in. And I agree truck brand loyalty is fierce.

For me, it's hard to imagine buying a truck based on which engine gets the best fuel economy unless I was a fleet owner pinching pennies. But as an individual owner, I want something that gets "good" gas mileage but also gives me other traits I want, like a good sound, and good power. In this case, I'd take the 5.3L V8 (preferably the 6.2L but not paying for a High Country).

My dad had a 2016 F-150 2.7L EcoBoost. That thing was amazingly quick and returned a lifetime average of 18.5mpg, but sounded like a leaf blower. After 33k miles, he traded for a 2018 F-150 with the 5.0L V8. The V8 is not quite as quick and is returning 16mpg lifetime average (3k miles so far). But to him, the lesser (but still decent) economy is worth the trade off to have a good sounding truck. I think I'd be in the same camp buying a Silverado...I'd prefer that nice deep V8 tone from a smallblock, not a 4-banger.

 

[AMERICA 123]

Look, I get all the love for the 4.3 and oh yeah why not do more with it..... but the comparisons being suggested between the 2.7 and 4.3 are likely way off the mark.

Simply put, a 4.3L 2019 C10 / K10 will not only not offer the same 'performance envelop'..... it is likely to not produce the kinda' mpg ratings many suggest.


I also would not assume Dynamic Skip Fire would 'work out' the same way on a big honkin' 4.3L / 90 degree V6 as on the V8s.

And ditto all that in terms of a Hybrid Siverado / Sierra.... plus......... all possible other vehicle installations....




Just look at what is happening with and among all the various 5.3s - the new truck, in spite of all the positives is evidently pushing so much air that in net, it ends up at best a 'push' ( no pun intended )..... or even...... a negative.

 

[AMERICA 123]

We need some one to post or clip an attractive presentation of the recent mpg ratings for all the various GM 2019 Silverado / Sierra.

Including the ones just released ie in addition ( and most often below the above list )

Sierra 'people' ..... including this poster are gonna' weep, and all the 4.3 people just are not going to believe what they chose to do - regardless of which generation design we are talking about.

Evidently in addition to the fail with too many PT variations ( and yep, that is the way it is actually ), and the ridiculous amount of air they apparently push..... some / many of the final drive ratios were also tweaked.

Sigh......

According to this poster's admittedly very shaky memory...... never in the history of the American Full Size Pick Up has somebody screwed this up like this.......... both in terms of results and especially via method and obviously........ very very twisted logic.

 

[mbukukanyau]

The entry level 2.7L Turbo has 310HP and 348ft-lbs torque with peak torque available from 1500-4000rpm. The entry level engine from Ford, the 3.3L has 290/265, and the Ram 3.6 has 305/269. That's 83ft-lbs more than the Ford and 79ft-lbs more than the Ram, which is huge and down low in the RPM band that will make a big difference. Don't get me wrong, I love big v8's, but for people who aren't shopping for a V8, and there are plenty out there, this engine will be more than enough. I think we will be surprised when they do a head to head to head comparison of the entry level trucks.

This person gets it. Fuel economy is just one issue. Do not be a joy beher

Yep.

2.7T clocks all other GM 2019 Silverado / Sierra gasser offerings.

And 'now' many of the 2019 5.3s beat the 2019 4.3s while the rest match .........

Except that you're overlooking that the "old" 4.3 will also make its way into the new lighter weight truck. Despite being hampered by only getting the old 6 speed auto it still achieves better highway fuel economy than the brand spankin' new, super high tech, highly complex and expensive to produce Turbo 4 that gets the new 8 speed auto. Often the simpler mousetrap is the best long term solution.

That said, I agree that more optional drive train choices is best for the consumer. To each his own.

The 'rated' 4.3 mpg dropped in some cases massively in new generation 2019 product.

( We shall have to wait a bit longer to see what the 2019 'old generation' 4.3 product produce - )


Lets just look at what the Silverado offers although the 4.3 Sierras are one of the few cases where Sierra and Silverado 'match' because about half the time Sierra now offers lower rated mpg than Silverado.


We have the previous listed above which evidently are the best the gassers offer plus many new ones including;

[tripowergto Jan2003]

Wow! So GM is purposely making the older carryover engines appear less efficient to coerce everyone to pay more to purchase the newest engine tech in the newest truck. I guess that's one way to make the Turbo 4 appear better than it actually is.

 

[AMERICA 123]

Well..... somewhere in all this is a bunch of legitimate activity whether appreciated here @ GMI or not but also.... I'll just bet there is some kinda' 'foolishness' afoot with the CAFE 'foot print' provisions - no pun intended.

Bad optics ( imo )......... which seems to be a Three Stooges specialty of late.......are a given no matter what reality turns out to be.

 

[lohchief]

Now I'm not going to say anything about fe/mpg's.What I will say is this,I live in a mountain state. Even pulling a small lightweight camper,you have the weight,and the increased wind resistance. That will chew up any fe/mpg's with no problem. And,just sticking to the posted speed limits,I just don't see getting 100k miles out of this engine. I think it's asking to much from a 4 pot turbo gasser. I just don't see the longevity of it,using it where I would be using it. I just don't see it lasting that long. Using gm's 'logic',they should have pumped up the 2.8L diesel a bit,and put on a better turbo to tone down the lag. I think that would have more appeal. Or,since they are supposed to bring out a I6 diesel in the near future,they should have developed an I6 turbo gasser as well. Both 6's will be about the same length,and take up around the same amount of underhood space. Use the 2.7 in the midsized twins,as well as the bunch of cuv's/suv's that they have,and will have.

The EPA highway test averages out to 48 mph, it is not a constant 48 MPH - think non-limited access highways with traffic lights and such. One reason why C&D's test is so neat (although I am curious about weather correction, my ATS can do 28-29 MPG at 75 mph in 85F, but 50F is more like 26-27 MPG).
