I believe one of the most intriguing facets of X1/9 history is the one described in SAE paper no. 890718, whose rather clunky title reads: "The Building and Test Track Evaluation of an Aluminum Structured Bertone X1/9 Replica Vehicle." The key word here is "replica:" The whole point of the experiment was to demonstrate how Alcan's adhesive bonding technologies could allow to more or less directly replace steel for aluminum, even in an existing body design. The company considered its X1/9 experiment a successful proof of concept, as the aluminum bodies delivered a comparable performance with the steel equivalent while weighing 30% less.
Had it been possible to redesign and optimize the X1/9 'shell for aluminum construction, it's likely the gains could have been even more significant.

The weight of a steel X1/9 body-in-white (unpainted shell) is 197 Kg, not 179 Kg as I’ve mistakenly indicated in the video. Sorry!

@giannisvourliotakis2006 Год назад

Very beautiful car, even today. Congratulations Mr. Bertone !!!

@Stratoszero Год назад

I really must get to this museum as soon as possible. One can never be sure about the longevity of vehicle collections these days. Thanks for the video, I never knew about the aluminium prototypes.

@Matteo_Licata Год назад

The former Bertone collection has been declared an item of national interest, which means it can’t be parted out nor exported. It’s not going anywhere, anytime soon :)

@Stratoszero Год назад

@@Matteo_Licata I hope it doesn't end up in one of the new breed of "modern" museums where half the available space is dedicated to interactive displays for school children! And then you have to pay twice to see the rest of the collection in the "vault tour". A big warehouse or aircraft hanger will do just fine! 👍

What an interesting detail to the x19 story , never knew they considered Aluminium.

@slicedbread9003 2 месяца назад

It interesting to note that Alfa made an aluminum bodied GT so they could achieve a weight savings for racing. It could be done, perhaps Alcan was trying to get Bertone to make a special run of aluminum bodied X1/9's. Interesting video. I had no idea that these were made. You deserve far more likes than I'm seeing. I think Americans thought of the X1/9 as toy or throw away cars. Not the brilliantly engineered little jewels that they were.

@Matteo_Licata 2 месяца назад

Thank you! I don't know if Alcan hoped for Bertone to turn the aluminium X1/9 into a production reality. My hunch is that Bertone and the X1/9, being small and with a low-volume product, made the ideal "guinea pigs" for what Alcan was trying to prove.

@Curva_West Год назад

I worked with an OEM where we had some issues with aluminium bonnet and rear hood splitting at design stage. We used CAE analysis to design it out, but aluminium also needed to be shipped in temperature controlled containers from Japan. Bel video Matteo. X1-9 videos are one of my favourites. Could you do a video on some automotive stories from Sud Italia?

@drewsimpson5967 Год назад

Up until the early 2000s there was an Alcan plant about 15 miles from where I live here in Scotland. I would have liked nothing better than for them to have been able to churn out aluminium X1/9's, Strada Abarths, and every Alfa Romeo of the time without exception. Regular, Fiat models also. Im not totally sure what they actually produced down there but the raw materials ran off onto the main roads and turned them pinky red, which looked great in the glow of headlights at night. Thanks for another great episode.

@Matteo_Licata Год назад

Sure Italian cars would have a better reputation, had they been all made out of aluminium! It took a while for our manufacturers to take rust protection seriously, possibly because they were too focused on the home market.

Fascinating. Thanks Matteo. I realise you concentrate on cars that interest you, but it triggered a few thoughts... The stainless steel Porsche 911 (there's one of the two in the Deutsches Museum collection in Munich) The aluminium bodied BMW 3 series, a racing homologation special from what I remember as the early 90s. I'm sure there are many other low volume specials like this.

@andykerr3803 Год назад

The stock steel X19 was was weak in the rear frame also, so that weakness they found was more of a design flaw. Just to look at it you could see there was little to no triangulation or bracing in the entire rear. Not the aluminum at fault there.

I never knew of those aluminum body vehicles. Very interesting, thanks for posting! Ah yes, fuel leakage in a crash in the days of steel fuel tanks. Normally no problem today (in Europe).

@timhancock6626 Год назад

I recall when Alfa Romeo 164s were exported to the USA the plastic European fuel tank had to be replaced with a steel one. Those were the regulations, but the logic of such a requirement was lost on me.

@mikebaginy8731 Год назад

@@timhancock6626 Ah, I didn't know that about the 164 fuel tank. Thanks for the info! Really strange, probably just a mens of complicating imports. But it took many years for US auto manufacturers to accept the many advantages of HDPE fuel tanks. The only advantage steel tanks had were a simpler means of reducing hydrocarbon emissions (permeation). But multilayer HDPE ist very effective. I'm American, now retired, living in Germany. I spent roughly 20 years in the fuel tank industry and was always amazed at the generally primitive (and more dangerous) fuel tank designs of US cars. Things are changing in this regard, but slooooowly.

@shankarbalan3813 Год назад

Such a lovely car. Why did they allow all these wonderful cars to just fade away….such a pity!

@FlashDriveFilms Год назад

There is more to the story. Two aluminum X1/9s were turned over to American car magazines for evaluation and a story. Taken to a race track, one of the journalists crashed one of the prototypes, comprehensively damaging it. The team from the factory quickly called in the other car, loaded them both on their truck and left.( I owned 4 X1/9s over the years and I always said "If only they had made them out of aluminum.")

@Matteo_Licata Год назад

Thank you for letting me know, as I hadn’t heard about this incident! Yes, I guess many X1/9 owners would have greatly appreciated the aluminum’s resistance to corrosion…

@patrickbrown7491 Год назад

Wouldn't rust! Should have followed with it! Wonder what happened to the tooling for the body? Should make aluminium body's now?

@johndavidwolf4239 Год назад

1) Although it doesn't "rust" aluminum does corrode, espically if touching other metals (galvanic reaction, noticed in early Land Rovers when first imported to the USA where winter roads are salted, a practice not done in GB). 2) In the video it was mentioned that they used the same tooling.

@alexandermathar7780 Год назад

The ultimate x1/ 9 would be aluminium body and Dallara race engine.

@alastairwatson3201 Год назад

Oh, what could’ve been! Imagine an aluminium-bodied X1/9, re-engineered to compensate for the reduced strength of that metal, and given even a modest twin-cam engine. It would’ve been an absolute giant-killer of a car, capable of high speeds with impeccable handling. Another lost opportunity for Fiat.

@GRAHAMAUS Год назад

Not to mention that they would likely have been more durable!

@johndavidwolf4239 Год назад

@@GRAHAMAUS : I disagree, as aluminum of the same strength has less fatigue resistance than steel.

@pashakdescilly7517 Год назад

@@johndavidwolf4239 Aluminium structures are usually made far stronger than an equivalent steel one in order to gain acceptable fatigue life. Bicycle frames are an example - aluminium frames are FAR stiffer than steel ones, and yet still fail at an early stage, which makes them too stiff to ride nicely. For a car structure to survive if made in aluminium, it needs to be similarly stronger, by design. However, it is stated in the script that the alloy bodied X1/9 performed adequately on the Belgian pave at MIRA.

I had one of these cars. It handled quite nicely on dry pavement. When it was wet or raining it would hydroplane right off the road. When you braked hard it would just slide. Slid mine right under the back of a Ford pick up truck. Dangerous!!!! It looked good sitting in the drive way though.

@johndavidwolf4239 Год назад

Sounds to me that was more a function of the tires you were running than the car.

@toddwilkinson1834 Год назад

@@johndavidwolf4239 maybe but they had excellent tread but as the motor is behind the seats, there is very little weight to the front end. Wet asphalt with a little oiliness to it is like a skating rink. On the interstate at 50 to 60 mph it wanted to hydroplane right off the road.
