Apparently GM is considering a number of architectures for the new Caddy ULS, including using a stretched version of the Vette platform. It also sounds like they are willing to re-engineer the current Holden RWD platform to work for it as well. (since Zeta is now out of the candidates).<p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote &raquo;</i></TD></TR><TR><TD CLASS="quote"> <p>Despite latest cuts, Cadillac's ultraluxury sedan still headed for production<br>RICK KRANZ | Automotive News<br>Posted Date: 3/29/05<p>Cadillac's ultraluxury sedan is heading toward production despite the loss of Zeta, one of two vehicle architectures considered for the car.<p>General Motors this month announced that it was halting plans for North American cars on the rear-drive architecture, a victim of budget slashing forced by the automaker's financial woes.<p>Jim Taylor, Cadillac's general marketing manager, said the product plan for GM's luxury brand was spared from GM's austerity moves.<p>"The ULS is still in there" said Taylor, who was interviewed last week at the New York auto show. "We didn't cancel any of the new-product programs, and we will be adding a few as well."<p>ULS is GM's internal code name for a rwd sedan that GM Vice Chairman Robert Lutz has been pushing. The car draws on styling cues first displayed on the Cadillac Sixteen concept. The car is expected to carry a sticker price in the $100,000 to $125,000 range. It will compete with the Mercedes-Benz S-Class and the BMW 7 Series.<p>The Cadillac ULS still is expected to go on sale by the end of the decade, but the vehicle architecture that will be used is still to be decided, Taylor says. A decision is expected early next year.<p>"Zeta was one candidate, and a Sigma derivative was one of the candidates, too," said Taylor. The Sigma architecture is used by the Cadillac CTS, SRX and STS. But now that GM has decided not to develop the Zeta vehicle architecture, Taylor said "anything that is rear-wheel drive that is on our shelf becomes a candidate" for consideration.<p>He said that includes stretching the architecture used for the Chevrolet Corvette and Cadillac XLR or re-engineering the rwd architecture used by Holden, GM's Australian unit.</TD></TR></TABLE><p>Autoweek

Zeta is the cheaper version of Sigma...so why in the hell would they even consider it for the ULS? Wouldn't they use another version of Sigma instead? I could see them re-engineering the holden rwd architecture, but it would need to be some major re-engineering...that architecture isn't exactly new, and with the work they put into it, wouldn't it be more worth it just to work on sigma being that it is most likely a better platform anyway? Stretching the vette chassis sounds interesting, but if this is going to be an ultra luxury sedan competing with the 7 and S, then the chassis will need to be stretched quite a bit...infact now that I look at a pic of the chassis, I don't think there is any way in hell this can be modified all that easily...<br><A HREF="http://img93.exs.cx/my.php?loc=img93&image=x05chcr0077jy.jpg" TARGET="_blank"><IMG SRC="http://img93.exs.cx/img93/5926/x05chcr0077jy.th.jpg" BORDER="0"></A>

<br>GM had better be careful. The buyers at the $100k and up price point are not going to be easily swayed by a re-worked Opel chassis. Even the Corvette/XLR may not have enough pedigree, presuming that it can even be stretched that far. <br>

i cant imagine how they will have large rear seating with the driveline tunnel effectively splitting the car in half; they will probably rework it to the point where it can scarsely be considered " Corvette" based

in which case would it even be worth it? I guess they could just remake a larger version of Sigma, and I am not saying to just lengthen it...obviously it is lengthened to its fullest more or less...just make a similar, but larger chassis...

GM and their platform problems.... <IMG NAME="icon" SRC="http://images.zeroforum.com/smile/emthdown.gif" BORDER="0"> <br>High end world class luxury cars don't have problems with their platforms... they just create new ones when they need to. <p>A $100K-$125K car deserves its own platform... not a derivative of a mid-size car that costs less than half its price.

And who ever said it was going to be a derivative of a mid-size car platform. Read the article carefully; the platform that they use will be extensively re-engineered for duty in this car. If it turns out to be a new version of Sigma, they wouldn't cut any costs on it (as in the way Sigma was being turned into Zeta), but would instead re-engineer it upward in terms of materials and costs.

One has to wonder if the large sedan may be a 4 seater with ultra luxury. The tunnel could easily be incorporated. Imagine 4 distinct seating areas with independent climate control, independent entertainment options and fully adjustable seats. Could be quite nice. The picture of the Cadillac Ultra Luxury Coupe that is also posted would appear that it could be based on the Corvette platform as well.

true, the phantom does have a 4 seater package and the rear center is scarsely used anyway

Using the Corvette "platform" should be easy. My guess is that the chassis would of course be lengthened and widened, but the major components could easily be shared. Given that we are talking about a vehicle with a roof, structural rigidity should be ok. We also do not know if the ULS and ULC are gargantuan or not. They could be as small as a true four-place XLR. The ultimate Cadillac may not necessarily be positioned as the Fleetwood say of the 60s was (i.e. length connotes luxury)

The Cadillac XLR is a different animal than the Mercedes SL. The XLR is for people who want to be cutting edge whereas the the Mercedes SL is screams old money. Just the fact that the XLR is in the hunt is all it needs to do to be successful.
