I thought this article would be interesting to you forum folks, whereas; it states that it will be used in the 05 stang.

Visteon's Slip-in-Tube Propshaft Improves Fuel Economy and Safety in Rear-Drive Vehicles
Tuesday June 15, 10:02 am ET


DEARBORN, Mich., June 15 /PRNewswire-FirstCall/ -- Visteon Corporation's (NYSE: VC - News) patented Slip-in-Tube Propshaft is now a weight reducing, quieting and safety enhancing feature on some of the highest volume sport-utility vehicles in the U.S., and will be available later this year on the 2005 Ford Mustang.

First introduced in 2002 on the Chevrolet Express and GMC Savana rear- drive vans, Slip-in-Tube is finding broader acceptance throughout the industry. By the end of this year it will be found on the 2005 Jeep Grand Cherokee, as well as the Mustang. By the 2006 model year it will be found on the high-volume mid-size sport-utility vehicles of another Visteon customer.

In manufacturing this first-to-market product, Visteon uses a Computer Numerically Controlled (CNC) cold-rolling spline process. This technique means that no material -- neither the inner nor the outer tube -- is machined away. The process allows the tubes to slide, or telescope, in and out of each other easily even under heavy torque. During some durability tests, Visteon's new, Slip-in-Tube Propshaft lasted more than four times longer than traditional propshafts.

As the two pieces of the propshaft telescope into each other a distance of up to eight inches, it improves the ability to absorb energy in the event of sudden impact. This eliminates the need for the heavier slip and stud yokes typically required with conventional propshafts. In addition, the telescoping motion reduces the unpredictable Noise, Vibration and Harshness (NVH) sometimes associated with typical machined splined components. The aluminum version reduces weight by as much as 30 percent over conventional propshaft designs.

Visteon Corporation is a leading full-service supplier that delivers consumer-driven technology solutions to automotive manufacturers worldwide and through multiple channels within the global automotive aftermarket. Visteon has about 72,000 employees and a global delivery system of more than 180 technical, manufacturing, sales and service facilities located in 25 countries.

So if you read between the lines you get the following formula:
better fuel economy=more real wheel hp=very nice hole shots=bald rear tires=buy new tires $$$$$

 

Better fuel economy is never a bad thing.

 

Wow, there's a lot of new technology going into the new stang. Usually that is reserved for other models it seems, and filters down to the mustang.

 

At first glance, I thought this would be a joke. Then I figured out:

Propshaft = Driveshaft



So is it me, or doesn't most everyone else but Them call these things a driveshaft?

On a similar track, slightly off topic, why DO they call things by non-colloquiar (sp?) names? Instead of 'steering wheel' they'll call them 'circular directional input device.' Or CDID for short.

Ok, I made that up. But still.

On the 'Propshaft' in the Mustang: Very Cool.

 

I think this new technology (i.e., slip-in-tube propshaft) is only used on the V-6 car. Not the GT. Does anyone know for sure ?

 

V6 features 1 piece S-I-T driveshaft. The GT features a two piece driveshaft with plunging CV (constant velocity) joint. The GT set up is much more sophisticated.

 

Hey Pony Chief, and Gizmo, take a Look at the top of Page 4 in the Brochure/Preview Guide topic, It says that both GT and V6 Models will have this slip in type Prop Shaft. It is as much a Safety Feature in case of an accident as it is a Noise Vibration and Harshness reducers well as an easier way to put it togeather.

And Houtex, to my Knowledge the "Prop Shaft" is the Part of the Transmission that connects to the Drive Shaft.

Yes, but with 18's and 255's at least you'd be a sissy who wasn't forced to apply for welfare.

 

TampaBear67: That sounds like a yoke. That'd be one big yoke. So, just cause it's drivin' me a little nuts, I did a little digging and found these:

That one's got 'propshafts' and they sure look like driveshafts to me...

http://waw.wardsauto.com/ar/auto_visteon_launches_new/
That one seems to interchange the words, so it appears to be the same thing, but for some reason, different?

And then there's this:

Second article, shows the propshaft.

Which looks to me like a fancy two part driveshaft. :scratch:

So they should call it a 'driveshaft.'

It's probably a European thing, the first site IS in Pounds, not Dollars...

It probably doesn't matter what it's called, though. If it makes the car go faster and be more efficent AND quieter to boot, well, sign me up, pardner. Yehaw!

 

Probably more efficient in the drivetrain loss as well. So is it confirmed that it'll have these for sure?

 

yeah i hear that except, they didnt figure into account US. b/c the lighter driveshaft means better accelleration.............which means fun pedal to the floor more, which equates to lower fuel economy
