GM to cut Chevy, GMC powertrain warranty

[LTC8K6]

Chevy 5.3 in truck form on rated fuel is 380/416

The 2015 Silverado with the 5.3L V8 has 355hp.

Where are you getting 380hp from?

On its E85 map power bumps up considerably. Just like the F-150 only gets rated power on premium.

What kind of crap is that? Why didn't you say you were talking about E85 in the first place?

It's fuel economy also drops 25-30% on E85, making it an untenable option in the real world.

Your remark about GM leading in the V6/V8 truck "hp/liter" wars remains entirely false.

 

[LTC8K6]

The Ford 5.0 in the F-150 was making 375hp on E85 in 2011, so it's probably well over 400hp on E85 in it's current form, if you insist on comparing with E85.

It's simply using whatever is in the manual. I knew the 5.0 was E85 capable, but I hadn't seen any official numbers for it. I thought maybe it was still using the same map as a lot of older Flex Fuel low compression engines did. Around here, E85 is quite a bit cheaper than gasoline, so lots of fleets ran it, especially when gas was 3.75/gal and higher, because even with the poorer MPG it still made sense to run E85. Years ago we were buying E85 at 1.79/gallon when mid grade gas was running 5.12/gallon plus. So there's nothing wrong with E85 numbers on a motor, at least around these parts.

No one is going to run E85 in their truck in the real world, imo.

It is at best, a wash on price.

It typically requires more frequent oil changes.

It cuts your range by a lot.

It is hard to start an engine on E85 in the winter, however, most states counter this by using E70 in the winter and labeling it E85. But the colder it gets, the harder it is to start.

GM to cut Chevy, GMC powertrain warranty to 60,000 miles



May not be a selling point; but it could become a rejection point.

Implies that one knows that the competition product is better than compared to yours.
you must be making an inferior product that you can not stand behind it.

I would worry that something that never broke is now going to be under-engineered. Well, I was leaning towards another Ford post Sync 2 headaches so who cares.

Well around here alot of us do, but that's beside the point. I was wrong on the 5.3L being so far ahead of the others, as I did not notice some of the other engines have gotten some increases in power. Good for me, cause I'm a Ford guy anyway. 😉

I think the hyundai example was more along the lines of they were a new to market manufacturer so people didn't know if the cars were reliable or not. having a longer warranty was the manufacturer saying, we build a good product and we will prove it is good by offering a 100k mile warranty.

Personally I don't care about the warranty. I'm not buying a GM vehicle if they had a 1 yr or lifetime warranty. I buy based on my perceived quality of car for the money I pay and the warranty doesn't factor in to my decision making .... unless I am have first narrowed my decision down two vehicles that otherwise are equal in my mind. At the point I may use the warranty as a decision maker.

When Hyundai first came to the US it's cars looked nice but earned a universal and well deserved reputation for falling apart after a couple of years. I know, I bought an incredibly cheap used one for one of my kids-it was a POS along the lines of a Yugo. Hyundai came out with the huge warranties to lure buyers to try them one more time and it worked spectacularly well for them.

Warranties do matter. The 150,000 mile on my Prius main battery was a big factor in tipping me over into the buy column. At that time the model didn't have much of a track record in the US.

In 2000, I got my daughter a used cheap Hyundai Excel that came with a "warranty" from the dealer. Electrical problems within a couple of weeks; required fuse block replacement and within a month the tranny quit. turned out the dealer did not submit the warranty paperwork and rather than fight me or the warranty, they took back the POS vehicle.

10 years later in Vegas, she swapped in her Pathfinder for a new Excel (she had forgotten about the old one); and was pleased with it except during snow in Colorado.

Now she has dumped the Excel for a Jeep and is pleased. More room to haul the kids and safer in the winter.

While i agree E-85 is a joke, there are some befits to running it in fleets as there are tax breaks, etc to be considered depending on the state you are in.

But no one was talking about fleets or discounts. He was talking about buying a Silverado because their NA engines have more hp/liter.

Except in reality, they don't...

Then he said he meant on E-85, one of them does have more.

But it doesn't, either.

The Ford F-150 with the 5.0 V8 leads in both cases.

😀

I'd run E85 in an EcoBoost F150 with an E85 tune. :awe:

Dude for the last time I'm talking about around here. We run fleets. We run ALOT of E85. They fill up on unleaded when they are out of the E85 area. Don't underestimate write offs and fleet discounts 🙄.

As for the 5.0, I'm still looking for official Ford numbers. On top of that it appears that the 2015 5.0 didn't necessarily get a power bump. The 5.0 mustang of previous years had to HP entries. An 87 octane that matched the 2011-2014 F-150 output. And a 93 octane that gave it 380HP. Low and behold, Ford has it in this years manual that the 5.0 is rated at 380HP *on 93 octane. So it appears that the power output is the same, Ford has just now put out different octane figures. Which makes sense too, lots of these high compression engines can make more power on high octane or E85 if mapped properly. It's like the EcoBoost, it's rated power, especially when towing, is on 93 octane.

Looked into this and it seems the base issue isn't as much the tuning as is the mechanical fuel delivery. Injectors and pump aren't big enough to supply that much E-85 as would be necessary. Though...I think that could be fixed. :wub:

If I got tax breaks and discounts, I'd run E85 too. Even if it resulted in less horsepower. 😛

Face it, the DOHC Coyote V8 is almost certainly going to lead in HP/L. It revs higher, too. 🙂

For 2015 it has new intake manifold, new cam setup, and new exhaust manifolds.

I'm really wondering how the Nissan Titan 5.0L diesel is going to be received.

revving higher doesn't mean anything if power is not increasing as it does. You're barking up the wrong tree, I'm a Ford guy. I'm simply using published numbers. The 2015 5.0 is not making the maximum power the 5.3 can in stock form. This debate has been worthless. I agreed that NOW the 5.0 is more competitive, especially close enough to not give any of the top three any particular nod in power. On the 2014 numbers that I had the 5.3 was more powerful than the 5.0.

 

[LTC8K6]

Logically, the 2015 Coyote would get roughly the same 15hp increase on E85 that the 2014 version did.

That would put it at 400hp on E85.

I think that is certainly in the ball park.

 

[LTC8K6]

I can't find any indication that the 5.0 hp rating is with premium fuel.
