(COMING SOON)
If you missed the CD4 Chassis School thread, please skim through that section. There are a lot of engineering terms and techniques that are used in the Fusion that will be found on the Mustang. This section will mostly deal with the shell and safety structure. Although, front and rear suspension conversation is welcomed...
Lighter? Heavier? Aluminum? Boron? Lots to discuss in a few short days...
Edit: Moderator, moderate this thread to the correct section. General S550... srry, on the go.
Edit2: Actually, I guess it can stay here, there will be a lot of pictures.
For fun, let's at least talk about what we MIGHT expect the S550 to be.
For starters, the S550 will probably use what is called an S-Brace to support the engine cradle. I can't say for sure if the engine cradle is Aluminium, I cannot tell by the Primer pics we seen. Probably not, at least not yet... The S-Brace is special, special because it is not shaped like traditional Unibody cars.
You see, the two S-Braces connect to what is called the Y-brace. The Y brace cometely eliminates the traditional Unibodys Torque Box. A tradition Unibody has a severe issue up front, the Alpha chassis GM has also suffers from this. The engine cradle supports connect in almost a 90 degree angle. That creates a "hinge", and more than one hinge to be exact. A hinge is a pivot point on a chassis/platform, in other words, it's a weak spot. Now, this can be made somewhat more rigid but, more metal means more weight. That hinge would need a triangular shape engineered from support to firewall... and all do... The other hinge is at the torque box location itself, again, this area is supported heavily. The rockers are a support beam for this area...
As I said, the S braces are curved down, it eliminates the 90• angles and the Y itself is no more than a big triangle. (The Triangle is the strongest shape in the automotive chassis/platform world.).
NEXT: SLED RUNNERS
Sled runners, if you haven't heard that before, STOP, Goggle it and brush up on it. It's good to know and always overlooked. The Fusions Sled Runners are HUGE, like extending all the way back to the rear seat area. They are not really large in the sense as physically big, the design is just more than what is usually used. These runners transfer the load from the Y brace evenly to the rest of the car. The Y brace supports the S brace, S brace engine cradle, engine cradle engine... Got it? Usually, a lot of chassis weight AND chassis weakness comes from this area... at the firewall.
What your seeing is an evolution of the Unibody here, it isn't like the Alpha or S197 or any other Mustang ever... This new "efficiency of design" also increases front impact performance, which is really good. What this system does, along with other systems I will talk about later, is transfers energy around the occupants... The force of a frontal impact is literally being channeled to the rear and out the back of the car... It's really neat...
THE PILLARS:
Silloutte Innovation, that's what this is called. In short, it's a Bullet shaped exterior with an Egg shaped interior. Now, this Bullet/Egg shape is not really visible, it's only visible in Physics. This imaginary 3d shape creates a strong structure, vastly increasing structural rigidity and occupant safety. Like the Triangle, the Bullet/Egg is another strong shape that is also aerodynamic.
Now, the A and C pillars are literally a single, solid piece. They are ONE solid piece and what looks to be like in solid relation to the roof. I mean, no roof gutters, the roof has become a stronger SHEAR PLATE (Google that).
