Interesting article on 2015 materials and design

Despite the fact that this Thread has been both de-railed and hijacked, seeing all these lovely Dog Pics makes it all ok. Just avoid putting condiments unto the "4 legged" variety.

Awesome info.

I wonder what the V brace is all about for the convertible. It provides better increases in rigidity than the strut tower brace.

Also, this shows that BIW weight is up about 1kg over 2014. So overall vehicle mass gains must be from the IRS or feature content.

That is strange, the front diagram that was showing the strut tower brace did not highlight the strut tower brace, rather the brace that runs along the back of the engine compartment (do not remember the name of it, but it was mentioned in another thread with pictures and installation instructions).

The V-brace was pointing to the back of the vehicle but had nothing highlighted to show where it attaches and spans.

Well gents we might have some issues with the 6G Camaro. The S550 body in white weighs say 347kg or 765lbs. Not terribly Heavy, not that light either. I am looking at the body of 4dr ATS, it weighs 284kg or 626 lbs.

Granted the 2dr ATS is overall a hundred pounds heavier that 4dr at approximately 3570lbs. But I am not sure where the weight difference is between the 4dr and 2dr body in white ATS's. let's hope it's all in the body, and the base for the Camaro is only 40lbs Lighter in the body. And still heavier everywhere else.

Also no one including the big three use the English system of measurement, except in cursory fashion in big meetings with regards to weight. Everything is done in Metric.

EDIT on the plus side:

ATS
– I-4 and V-6 cylinder engines with manual or automatic
transmissions, rear and all wheel drive variants were
required
– GVM ranges from 1910 to 2125 kg
– V8 engines were not treated as part of the bandwidth

The main competitors to the Mustang were always larger, like the Camaro and Challenger. The Challenger is still large with the latest models. The 6th gen Camaro will be smaller but doubt it will be the same size as the '15 Mustang. That is my observation.

The Camaro had to get smaller since it was a good bit larger and heavier than the previous Mustang.

Do you think the new Camaro will be lighter than the S550? The Camaro will ride in the ATS chassis but I doubt it will be the same size. The ATS is a small car.

Great OP. It's fantastic as a consumer to see the intricate details and engineering going into the product.

I think it is referring to the overall width of the vehicle, which was increased about 3" in the rear, improving handling and performance (competitiveness). Just my guess.

Yes, the "L factor" that was quoted on that page is the mass divided by (torsional (twisting) rigidity multiplied by the "shadow area"). Meaning that calculation looks better with more rigidity and more length times width. If you keep the mass the same but increase rigidity and shadow area then it is more competitive by that measure.

Thanks that makes more sense. Glad they took to heart some of the complaints about body flex, cowl shake, vibration, poor ride quality.

On e of the things that has struck me is the fact that in reality when you compare equally equipped vehicles, automatic base GT's for example, the new Mustang only really gained about 65 pounds. Of that a solid 30 pounds of it is just in the new exhaust system and maybe another 5 for improved brakeswhich are very near the old Brembo package on the s197.

so what you have is a vehicle that increased its rigidity, ride quality, handling, and interior while only really gaining about 30 pounds. In my opinion that is really good because for did not use a whole lot of exotic material to help the car be lighter

I don't see the 6 gen v8 camaro being much lighter than the current car

In this picture, you can see the additional support that connects the rail to the Rocker. This appears to be a bit more direct than the previous car. It is also bridging the rail to the rocker, furthermore, kinda eliminating the middle man (those miter cuts and torque box). This looks heavy duty compared to the ATS-V's Alpha. It's all teeny tiny...

That is a GREAT find. Fascinating stuff! I wish that I understood half of what your talking about. I won't pretend that I do. I'm looking at that photo that you attached, is that workers at the FlatRock Plant?

You might find this funny...while I zooming in and studing this photo, I notice the black fire wall plug, just above to the left of the steering colum penitration where I spent some hard time removing my sound tube.

Great find. For the curious that wants to know about the different materials and for the engineers that might understand what they are reading: http://www.autosteel.org/Research/AHSS%20Data%20Utilization.aspx

Interesting, just noticed this made the front page! Cool!

Glad you guys and gals are enjoying the read, was looking for more information about the design of the front windshield in the convertible to see how it was strengthened for roll over, and stumbled across this presentation.

Best Regards,

Chris
