I like the part where you can hear the driveshaft isn't balanced well enough to be going that fast and he keeps his foot buried.

What kind of rpm would that driveshaft have been spinning at when it let go ?

Yes, we Europeans lust after the V6 Mustang (screw the GT) for our high-speed autobahn driving. In fact, it's selling by the thousands 'round these parts. It's the great fuel economy, low price and substantial dealer network that seals the deal. Jesus cartwheeling christ what a dumbass. Hope the dealership denies each and every one of his warranty claims.

On one hand, there is zero excuse for Ford to let that car out the door with a driveshaft that's imbalanced at all. It may be "just a V6" but it is a 300hp car, and five years ago if someone had done that in a GT nobody would bat an eye / everyone would be screaming about Ford's poo poo quality. On the other hand, there's equally zero excuse for why he kept his foot in it with an awful racket like that. Presumably he had to feel it too. Way back in the early days of the fourth-gen F-body, a number of six-speed cars got out with imbalanced driveshafts, but you had to get it up over 100 to notice. GM still put out a TSB for it and gave anyone who complained the aluminum 1LE driveshaft.

Around 115 it already sounds like something is out of balance. In the comments he says they should have a better drive shaft, but I have a suspicion that if his drive shaft fails at 25 mph over the stock limit something else is not too far behind, or at the very least Ford felt it would be hard to control at those speeds. My father always told me that car manufacturers pay a lot of money to people to design cars, and they are smarter than your dumbass friends or the guy at the parts store.

There's nothing wrong with the design of the car as a whole, the same car with a V8 will do those speeds without batting an eye, and I doubt the V8 has a significantly different design on its driveshaft - just bigger / better-balanced parts, my guess.

At my old job we made a bunch of half shafts for old Fords, and the quality of the original parts was always appalling. Granted they were like 40/50 year old forged shafts but still, it blew my mind that the thing would actually spin to any speed and not shake themselves to pieces. The worst were Anglia shafts, and while I know nobody on earth is going to approach any sort of speed in a stock Anglia I would still be nervous if I were ever in the back of one.

I'm not saying there is something wrong with car as much as there is probably a reason for the limiter, even if it is just to sell v8's. I also totally agree that Ford should not treat the v6 as "just a V6" and treat it as a 300hp motor. That applies to many recent cars, we are making more power per cubic inch than we ever have before, so puny 4 bangers are now regularly putting out over 200hp, and v6's can put out over 300. Hell, the F20C Honda put in the S2000 has more horsepower than the 350sbc Chevrolet put in Camaros in the 80's. (I would like to note that I am fully aware the s2k has no low end to speak of)

As far as I know, most modern vehicles save the last few minutes of OBDII sensor (which includes speed) data if they experience an airbag-triggering event. I may be wrong.

To go back to the fourthgen example, if you didn't tick the "Z-rated tire" option on an LT1 Z28, you got a speed limiter. If you did, the limiter disappeared. Also, apparently the GT does have a significantly different driveshaft design - apparently it gets a two-piece. That seems...dumb. This isn't the '80s where the base Mustang is a Pinto-engined slug, or the '90s-'00s where the V6 is only the providence of high school girls.

One reason you can't make part of a unibody out of stainless is that welding stainless to mild steel = galvanic corrosion out the rear end, iirc. If the welds even hold well, which they might not. Also it's not as strong like someone else already mentioned. Rusted weldnuts inside the frame are the bane of my existence.

Here's another angle that just showed up on a news article: Absolutely nuts, and I just can't go over how undamaged the side of the car actually is. Hardly even a dent or crease.

How does the entire side of the car shear off undamaged like that? The wheel is still even in the proper place. How is that even possible, considering all of the support structure holding it there was obliterated? It's either a hell of a coincidence, or someone placed it there after the fact.

The wheel is probably still attached to the front corner of the car by the strut tower.

I got to go to the 25 hours of thunderhill this year and crew for Boothman Racing. I knew some of the drivers from the FFR series in the great lakes region but had never seen this particular car before. We'll be racing this  We qualified 9th I think, and the start of the race went well. About 4 hours in the car won't go into gear. Pulling the trans shows us this.  Pop in a new clutch, send it back out, it seems like smooth sailing from here on. We've had our big failure for the race right? Dropped back to somewhere around 60th overall, and climb back to the top 30 through the night. Around 6am the driver gets on the radio and says "the cars on fire, I'm getting out". This was maybe 5 minutes after a stop, new driver and full fuel. The race is red flagged and a couple minutes later a worker tells us the driver is ok. 25 minutes or so later, this is dragged in.   (pics from daytime because all the night ones I took sucked) Another worker took a picture during the fire. They say they tried to put it out, had no effect, and waited for it to burn down first.  19 hours down, 6 to go. Inspecting what was left afterwards we found the front mounting points of the fuel cells straps had failed where they were welded in to the rest of the chassis. They had bumped the tank from 22 gallons to 32 if I remember correctly and didn't reinforce the mounting points. I believe this was it's 5th 25hr. In car video from the start of that race. That channel has lots of good in car FFR action with no music too. http://vimeo.com/33401052

I was the head mechanic for 949Racing/Supermiata (E2 winner/8th overall and E2 3rd place). We've got in-car of the fire starting as the driver went into 2 - it's a serious  moment. Our only big failure of the race in the lead car was losing the LF wheel (improperly installed OEM studs). Took us about 5 minutes to get the hub and rotor replaced and get the car back on course.  Cars before the race:  First 25 hour for about 90% of the team - not a bad result for our first one.

The upper ball joints on my mom's Ranger were worse. The right side had a rusted tear in the top metal cap, there was no grease inside, there was a solid 1/2 cm play in all directions. I replaced brake discs, bearings, pads, UCAs, lower ball joints, put it back together, one day later it blew the hardline that fed the back brakes. Fixed that, then the filler neck rusted through. Replaced that, still leaks a bit, need to drop the tank to replace the hose. The tank is plastic, so it CAN'T rust. Noticed while I was under the truck for the filler neck that the bedliner is now the main structural component of the bed. gently caress that truck.
