In that Fiesta picture it only mentions the A-pillar as using ultra high strength boron steel. The B-pillar is in the same color but it only says it is shaped for ultra-high strength. (so I'm not sure if that uses it or not)
The quote from the Ford press material about the Fiesta is, "More than 50 percent of the body structure is high-strength steel, including grades of very high-strength, dual-phase steel and ultra-high-strength aluminized boron steel."
https://social.ford.com/our-articles/cars/fiesta/ford-fiesta-will-it-blend/
It doesn't sound like very much of it uses boron steel, but it does have a lot of other high strength steels. Based on the Mustang graph it looks like about ~65% of the BIW uses high strength steels, with about 15% being boron steel. That sounds like at least as much, if not more high strength steel and boron steel than the Fiesta.

Pill,
From the Ford, Chevy or other manufacturer spec sheet or catalogue could you please point out the RACE curb weight of a car? I m really curious! The point is, you can strip down or put one gallon of fuel in any car but you cant fool us by claiming lower curb weight numbers than the manufacturer's, in this case the base gt s550 weight is proven to be 3705 lbs period, and that is with a full tank of gas! Now you go cry in a corner!

Fiesta used about 55%, the S197 used about 10%. The S550 is a little bit more. However, the S550 is a Mild Steel nightmare.
I don't need to cry anywhere. I don't care about the official curb weight. For some reason you do. I have never raced with more than 6 gallons of fuel. The car I replaced was within spitting distance of the new 2015. I know the Base GT was lighter, I know many were led to believe these S197's were lighter, mine wasn't as was Terrys. Our fear was that the 3700+lbs car he weighed (his own) was final (also empty). He, as well as many others, we're pleased that the real world gain wasn't bad.
A Base GT was never the performance benchmark.
Facts are facts, the cars didn't gain as much as we though given the standard equipment now.
A perfect example is BMR's GTPP that weighed 3736lbs full and nothing removed. Just removing the 32lbs the PP wheels and tires add brings the figure below Fords advertised curb.
Brakes? 20lbs
Suspension? 10lbs
Radiator? 5lbs
We are already well below the advertised curb as is. This is using BMR's list mind you.
I am eager to hear how Ford added over 65lbs in equipment but only increased the curb weight by 34lbs in BMR's case.
We also know the German KERB of a 2015 is 3639lbs. That is a Premium and Performance Pack too. That is all standard... 90% fuel.
I wouldn't count the Mustang out yet. They had no Camaro MSRP to beat over there. Some of that will wiggle its way home.

The Fiesta uses about 55% high strength steel. Most of that is not the boron ultra high strength steel. Based on the information I've showed, it looks like the Fiesta actually has a little more mild steel than the Mustang percentage-wise.

UHSS is a hugh weight savings material just on design efficiency. Boron and UHSS are not lighter than Mild, it just takes far less metal to achieve the same results.
Have you seen the S550's structure detailed? The Fiesta is far more complex.

Don't listen to garagelogic, many members here are reasonable and don't want to be apart of an echochamber where everyone agrees. There are errors in ThePill's posts and he does have an axe to grind with GM. I personally don't care what motives he has, I care if what he is saying is right.

I know that. All I'm saying is the Fiesta does not use nearly as much UHSS as you say, it is mostly just regular HSS.
Yes I just linked it to you earlier. Unless there is a more detailed one somewhere...

Ah tango!
There is a specific reason the Fiesta did this though and it wasn't all in the name of weight reduction.
A smaller wheelbase or compact car has a deadlier kill zone. Not enough hood or trunk to absorb energy. The structure requires more quality steel to allow the safety structure to hold its shape.
It may not translate as well in the Mustang... I just don't see how it wouldn't benefit.
If there is a benefit, it very well could be used where Aluminum cannot. If this is the case, the S550 being a larger structure, could see a larger structural loss. An example of this would be an F150 losing 700lbs going to AL, while the C7 only lost 100. Less mass, less loss on the table.

Yeah, don't listen to me, somebody who has owned a number of Mustangs, including two modern GT500's and a 2013 Boss 302, as well as several performance vehicles from GM and Chrysler in the past 15 years. I'm just a Ford fanboy who agrees with everyone's opinions as long as they are pro-Ford!
Please.

What do guys think how the new gt350 will hang with a corvette stingray with the z51 performance package? Assuming similar price range? I don't even know why we are not comparing a gt350r to a zo7 vette either?
i think the GT350,will be right there with the z51,or beat it,as long as chevy trends driver randy is not the test driver.we know he is pro Garbage Motors.:lol:

The Vette should still take it. That Vette will weight just under 3400 curb and just can't see the 350 coming in under 3700lbs with the track pack. The GT will have more power, but will need it for the weight. But I don't think it will smoke it as it should be close.

I think they'll be right about even in a quarter mile, but the Vette will take the 350 in a 0-60 race due to it's down low torque. It'll be an interesting matchup for sure as the 350 doesn't have any performance data out yet.
Edit: http://www.corvetteforum.com/forums/c7-tech-performance/3372952-c7-fast-list.html C7 times... impressive. The 350 has its work cut out for it.
