Ford V-6 beats v-8's in towing competition

[crazyal]

The real question to me is how much does it cost. I don't care if Ford can make a 3.5 act better than 5.x V8 if it cost twice as much. Twin turbos can't be cheap to produce. Does this need something higher than 87 octane to run correctly? It does have nice low end torque numbers. A 2 mpg boost in MPG will only save you about $1200 over 100,000 miles.

OK, I just read the article. The only things it proves is that Ford is not lying about the power numbers. Most hp and most tq, especially at low rpms, is going to win the race.

Real world mpg's and longevity will be nice to see. I am a Ford guy thru and thru mainly because I have had flawless service for many years. I would hate to end that streak on an unproven V6 on steroids. If it proves out over a couple of years I would be interested.

If this technology is that good, let's see it on a large displacement motor for the Superduty's. Imagine 500 hp and 600 lb/ft on something like the 6.2l V8.:licking:

It's a great engine for the those who want the quickness and fuel economy unloaded but don't compare it to a truck and engine made for towing. Those turbo's won't last 50k miles with regular towing. I bet it will be a good $1500-$2000 repair too!

Why would the turbos not make it 50K? All 4 turbo trucks, Diesels, I have owned have never had a turbo problem with 2-3 times that many miles.

Its not a huge V6.


The Ford is a 3.5L up against the GM 5.3L and the Dodge 5.7L. As for economy I have seen test stating about 24mpg unloaded. I am impressed just like I was with the 3.8L Twin Turbo Grand National when it came out and some of the turbo charged imports. I just wish they could do better than 24mpg.

Chris

The Grand National's of the 80's all had just 1 turbo, even the mighty GNX. A few imports had twins like the Mits 3000 Gt and Dodge Stealth.:thumbsup:

Typical Ford horse squeeze!
Ford rear end ratio- 3.73
Chevy rear end ratio- 3.42 (they even call it "the Econo rear end" in the text)
Oh, let's have a zero to 60mph test!
The test is meaningless! Maybe that is why their #1 spokesperson also has a show named Dirty Jobs.
As stated, let's see the fuel consumption during the test.

Well Ford declined my offer to be in the test go figure.... Oh and it gets 34 mpg in town....



Typo that should have been 3.4 gpm :laughing:

Now if Ford can make a V6 SOUND as good as a V8, I'll be interested, but I'm not counting on it.

My wife's 86 Buick T-Type (3.8 SFI Turbo) sounded pretty sweet, and went like a ...... ape.

Turbo longevity aside, I think the main point is that most people drive their truck unloaded 90 percent of the time.

Those who buy trucks because they feel manly may drive them unloaded but not those who buy a truck for a purpose. My truck is NEVER empty and has a trailer hooked to it more often than not.

The point is they are trying to convey this truck/engine combo as "better than a V8 when towing" and it clearly is not.

Why would the turbos not make it 50K? All 4 turbo trucks, Diesels, I have owned have never had a turbo problem with 2-3 times that many miles.

BIG difference between gas engines and diesel engines and just as much difference in turbos as well. The main killer is the rpms, a diesel will spend most of it's time at around 1500-2500 rpms where-as a gas engine will be more like 3000-4500 rpms. That turbo impeller typically spins at around 100k-150k rpms and about HALF that on a diesel engine. A high-revving small displacement V6 will run higher than normal rpms.
Secondly is the vacuum that's created when the throttle plate on a gas engine closes (you let off the accelerator), this creates a huge spike in air that goes back to the turbo, most of it is bled off via a blow-off valve but it still puts strain on the turbo. The diesel engine does not do this.
Thirdly, a diesel engine holds a TON more oil 10-14 quarts vs 5-7 quarts. This means the turbo which is oil-cooled as a larger supply of "clean" oil that will last longer and typically goes through a larger better oil filter.

I am interest in seeing what they are like when they are actually released. May say goodbye to my silverado if i can get 25+ mpg unloaded. AND - I can get rid of XM and go back to Sirius!

Makes sense. I really did not know why. I have had a turbo diesel trucks but never a turbo on a car but do remember dating a girl in HS that had a Dodge Daytona Turbo and I can remember her dad replacing the Turbo in it a few times. I think it was a Mitsubishi Engine.

This motor will be interesting to watch. I can not wait to see what the competition comes out with. The way this thing makes power down low really impresses me. As for running a 0 to 60 race its very relevant. Merging into traffic on the free way is a pain pulling a trailer in a under powered truck. This is a place that makes or brakes a truck in my eyes. I would still love to see a comparison of the new Ford 6.2, the GM 6.2, and the Hemi Dodge. That would be a fair battle.
