V8 Silverado makes CNN.com 13 Great fuel-efficent list...

Full-size pick-up
Chevrolet Silverado
Fuel economy: 15 mpg City / 20 highway
Twenty miles per gallon on the highway might not seem like a bid deal. but we're talking about a big truck here. Consider that the Silverado's fuel economy is identical to that of the car-based V6-powered Honda Ridgeline.

The Silverado, and its GMC Sierra twin, also have easy-to-drive ride and handling qualities that are unmatched by any other full-sized truck.

Heh - they also get the same basic mileage as the V6 Silverado and GM's compact trucks, as well.

Does the 5.3 feature DOD or direct injection yet?

The 5.3 has offered DOD (or "AFM" now) for quite some time.

Heh - they also get the same basic mileage as the V6 Silverado and GM's compact trucks, as well.

Yes....and the same basic mileage as the V6 compact trucks from Nissan, Toyota, and Ford too.

Yes....and the same basic mileage as the V6 compact trucks from Nissan, Toyota, and Ford too.

And tow more than those V6's when the need arises.:D

"The new Silverado: V6 gas mileage, V8 power." :)

And I imagine it only gets better from there.

Yes....and the same basic mileage as the V6 compact trucks from Nissan, Toyota, and Ford too.

More or less, yes (though the Taco does tend to get a little better mileage than the Colorado, it's still a pretty insignificant amount).

But the article already used the V6 ridgeline as an example. Thus the comparison that GM's V8 was more as fuel efficient as competing V6s was already made. I wanted to add to that point what the article didn't - their V8 is as fuel efficient as their own V6.

I've long since been a proponent for not automatically dismissing the 'larger' motor choice simply due to fuel economy concerns. My wife's 4runner for example would have only suffered by half a mpg going from the 4.0L V6 to the 4.7L V8. She was assuming it would be much worse.

And while we're on the topic - the Tundra's 380hp V8 gets 16/20 in 2WD flavor.

That's more power, plus slightly better economy than the subject of this article.:shrug:

Oh, and 1 mpg lower than the Chevy V6.

What's my point?

That articles like this that simply present "engine X > engine Y" in a very limited and selective perspective are pretty misleading...

That's great glad to see it. I wonder what the observed MPG is?
I know my friend with his 06 hemi Ram quad cab only gets 10mpg.

Silverado rating quoted using 2008 standard. 2007 Silverado mileage was rated at 16/22 under 2007 standard; dropped to 15/20 under new rating. Tundra is 16/20 under 2007 rating and drops to 14/18 under 2008 standard. Let's compare apples to apples.

You are comparing 4x4 Silverado to a 2wd Tundra. 4x4 Tundra with the 5.7L is rated at 13/17mpg the 4.7L is rated at 13/16mpg

2wd vs. 2wd the Silverado still gets better mileage http://fueleconomy.gov/feg/findacar.htm

FWIW, my '07 Tahoe is rated at 15/21mpg, and with 25,000 miles on it, it has gotten a consistant 15.5mpg in real world driving (roughly a 50/50 split of hwy/city) On a level hwy, it will average 20mpg at 65mph, but start going up and down hills and it falls pretty quickly.

I don't see which engine they are talking about? the 4.8, 5.3, or maybe the V6?

You guys are missing the point. My point was not that the Tundra gets better mileage - my point is this article is misleading based on selective specs.

Let me give you another example:

What if I were to write an article that said.

THE NEW TUNDRA IS SOOOO FUEL EFFICIENT!

JUST LOOK AT THE PROOF BELOW!

With the 2008 EPA ratings, the 380hp 4x2 Tundra is rated at 14/18 and the 4x4 is rated at 13/17.
For comparison's sake, GM's smaller and lighter Silverado with a much smaller and far less powerful 200hp 4.3L V6 engine only manages 15/19 in 4x2 form, and 14/18 on the 4x4 model.

In other words the smaller, lighter, and far less powerful offering from GM only manages to average 1mpg better than the mighty Tundra.

All hail Toyota's green engineering!

Well, what other facts are we missing between my spoofed selective article and the real selective article in the original post?

Based entirely on the new 2008 ratings:

-GM's 4.3L V6 is actually half a mpg worse than its 5.3L V8 in average economy.

-Toyota's weaker and smaller 4.7L V8 gets worse mileage than the 5.7L does. Similarly, GM's 4.8L also gets worse mileage than its 5.3L does.

-GM's 5.3L V8 averages 1mpg better in both 4x4 and 4x2 forms (though it does come in with significantly less power), than the Tundra's 5.7L V8

-GM's 6.0L V8 comes fairly close to Toyota's 5.7L's power and in 4x4 flavor is rated at 13/17, which matches the Tundra's 5.7L economy, and in 4x2 flavor is rated at 13/18 which is 0.5mpg average worse than the 4x2 Tundra's economy.

-Both 6-cylinder models from GM and Toyota offer 15/19 mpg in 4x2 form. The Tundra offers more power, though.

Etc, etc.


Looking over ALL of the facts I wouldn't say that GM or Toyota offer significant advantages in economy over one another, OR over the majority of the rest of the competition for that matter.

Despite what the real article or my 'spoof' article might otherwise lead somebody to believe.

I was just posting it because GM got some good press...

I'm not saying you were wrong for doing that.

I'm simply saying the 'good press' isn't very accurate if you look at the real numbers.

Then again I will say I do see Toyota getting regarded by the press as a very fuel efficient company when they're, in reality, no better than GM with the exception of possibly their Prius hybrid, compact Corolla, and subcompact Yaris. Oh, and the hybrid Camry too. Wait... maybe they are a little greener in some regards...:think::p

The picture of the tacoma is a TRD 4x4 which gets no better than a fullsize truck. The prerunner quad cab gets no better either. We drove our 05 prerunner to FL and back and averaged 19.6 mpg which was all highway. The speed was 70-75 mph. I get 18 out of my silverado at 75mph. The tacoma picture they should have been showing was a regular cab 2wd with a 4 banger. There will be some people who now think a TuRD 4x4 ex cab tacoma gets 26mpg :lol:

Good for GM :D Anyone noticed GM has been getting some pretty positive press the last year or so?

I'm simply saying the 'good press' isn't very accurate if you look at the real numbers.

Chevy Silverado has the most fuel efficient V8 and it is on par or better than many V6 trucks, based the #'s I've seen that is pretty damn accurate. :shrug:


-GM's 4.3L V6 is actually half a mpg worse than its 5.3L V8 in average economy.

-Toyota's weaker and smaller 4.7L V8 gets worse mileage than the 5.7L does. Similarly, GM's 4.8L also gets worse mileage than its 5.3L does.

4.3L is good for just two things, being cheap and reliable. It cost its owners very little in maintenance over the 250K-300K miles they should be good for. Just a solid old school engine.

4.8L needs DoD/AFM and Toyota's 4.7L needs to be replaced.

I suggest reading the article again. It's fairly obvious that they're trying to leverage the 5.3 V8 as being 'ultra efficient' because it's as efficient as Honda's V6.

When the reality of things is that:
-The 5.3L is barely more efficient than the competition's V8s, while in many cases providing less power.
-As a general rule of thumb V6s in big/heavy vehicles don't tend to get much, if any, better mileage than the V8 counterparts - mainly because they have to struggle quite a bit more to pull the weight around.

I think you are reading to much into it. I agree with you though about the V6's. V6 doesn't really get you anything over a V8.

Don't forget 1mpg = 5-7% in the truck world.

That wasn't true 3-5 years ago. If you wanted fuel mileage from a full-size, although weaker, you got a V-6.

Threxx haven't you learned your lesson about posting anything by now.

;)

:think:
2002 Chevy Silverado EPA rated mileage:
4.3L V6: 15/20
4.8L V8: 15/20
5.3L V8: 15/19

Nope.

I know I went to school with a guy who had a 2x4 F150 with the V6, standard cab and bed, he said he would consistently get at least 20mpg.

EPA ratings aren't worth crap, they're only a guide. I know people who consistently average 19-20 with a 4.3L fullsize GM truck, and some guys that can't seem to get better than 16-17 highway with their 5.3's.

Go back even further to the 88-98 trucks that came with the 4.3L and 5 speed.

In real world driving they got similar mileage to the newer ones (the 4.3), but the 5.7/700R4 was only good for 13-14 city and 16-17 highway in 2wd trim. 4x4's were lucky to get 15 highway.

Smart ass :D

EPA ratings are generally good enough for general relative measurement. In other words you may not get the rated mileage, but you will still typically experience the 'difference' in mileage between one and the other.

I think the anomaly exists in the fact that a person with a 4.3L V6 is more likely to take it easy - they're not going to have much fun by mashing the pedal - they're not going to impress anybody including themselves, and really, if they BOUGHT the V6 in the first place, then they're most likely a conservative driver anyway. The guys buying the V8s probably buy them because they enjoy the power - and they intend to use it.

The EPA ratings are given by requiring all of the vehicles to accelerate at the same leisurely pace. So if the V8 drivers can't resist using the extra power on tap then they're going to get worse mileage.:p

FWIW, my 2004 Silverado (2wd, ext. cab, 5.3, auto) gets virtually the same day-to-day mileage that my 1996 C1500 (2wd, reg. cab, 5.7, auto) did, maybe a tiny bit better. My '96 would pull down 18 mpg week in and week out. My '04 gets closer to 19 under the same driving routines. I'm guessing the '04 is a bit heavier since it's an extended cab and the '96 wasn't. I do know, however, that the 5.7 "Vortec" in the '96 had significantly better low-end feel. I drove a 2001 reg cab 4.3 auto once as a loaner and it struggled to maintain 70 mph into a 20 mph headwind.

I know I went to school with a guy who had a 2x4 F150 with the V6, standard cab and bed, he said he would consistently get at least 20mpg.

On the highway and with 3.08 gears, I can see that. In the city, that thing won't get out of it's own way, which means squat for MPGs.

Unfortunately, that makes that particular F-truck a glorified car that tows less than a 4 cylinder Ranger.

Don't forget how old the 4.3 is compared to the new V8's. It's for most purposes on par with the truck V8's of 10 years ago.
