The thing I never understood was why, on the cheaper V6 model (Chevy then, and apparently Ford now) did they use a 2-piece driveshaft, when the V8 models got a one piece (Well, Chevy did, and my '02 Mustang GT does)! (I swapped out to a 1 piece, it's a direct swap, takes about 10 minutes). I can imagine that the shorter sections are cheaper to manufacture than one long one, but the added cost of the extra u-joints, bearing and mount for the center bearing would outweigh any cost savings, right?
Granted, I think the 4th gen V8 F-bodies had a one piece *aluminum* driveshaft, but the 2-piece was steel, why not just do a 1 piece steel and save money on the materials? It must have worked out cheaper to do the 2-piece, but I sure can't see how.

Did'nt you see that mythbusters? It wont happen... Be honest when you think about a 3500lb car traveling that fast is a LOT of energy and most driveshafts being hollow will not take that kind of load before crumpling or the u bolts breaking away from the rear axle or the differential carrier tearing away from the frame.

Before we get started, we feel the need to repeat the standard issue warning about automotive stupidity: Do not try what's shown in this video, and if you do, make sure it's in the safe confines of a legitimate track facility.
One individual recently learned firsthand what happens when you remove the factory's 112-mph speed limiter on the Ford Mustang V6 and proceed to accelerate to 135 mph. The vehicle lost its driveshaft, which turned itself into a spinning hunk of metal that tore into the floorpan, bashed through its interior bits and generally caused mechanical mayhem.
The term for this type of failure is "catastrophic."
So, what happened? Well, we might first point out that the driver of this particular Mustang was clearly still accelerating after the drivetrain started making suspect noises – never a good idea. We have to imagine the vehicle was vibrating like an overloaded Magic Fingers bed before things went sideways.
As it turns out, the 305-horsepower and 280-pound-feet of torque 3.7-liter V6 Mustang is built with a 2.73 rear gear ratio and a lightweight, one-piece driveshaft that's engineered to toe the line between fuel economy and performance. That driveshaft is part of the recipe that allows the coupe to yield 31 mpg highway – it simply isn't built to handle the type of speeds the owner in the video after the jump submitted it to.
In a statement to Autoblog, Ford said that the Mustang V6 is "the ultimate in fuel economy and performance," noting that owners looking for more speed should look toward the Mustang GT with its 412-horsepower V8, heavy-duty two-piece drive shaft and variety of rear axle ratio choices. The Mustang GT is speed limited to 145 mph from the factory.
As an aside, we would also like to point out the idiocy of trying to film oneself at triple digits by hand. While the YouTube description says that the impromptu test course is a "closed" road, it looks like it might be a public roadway. The videographer is lucky to be alive. Keep it on the track, people, and hit the jump to see the clip for yourself.
