Re: FIAT Buys Cadillacís Sigma Platform For Alfa?

The initial development of the GM Sigma platform was actually done by Holden in Australia in the late 90's, however, they chose not to use it locally and therefore developed the larger Zeta platform for use on the current Commodore range.

Not sure if Fiat will buy the Sigma for Alfa use, but Saab (amongst others) have rejected its use and therefore its currently solely used for Cadillacs. The Zeta platform will be used in the new Chevy Camaro and Pontiac G8's in the USA.

GM also have the ***** (yep the wrong spelling of Alfa) platform (again developed by Holden) that is a smaller (than Sigma) midsize RWD (read 3 series BMW) and can accommodate 4cyls, V6's and V8's which might be a better prospect for FIAT

Who knows what ALFA will get, but a return to at least some RWD cars will be a huge leap forward for the company

I dunno..they have an engine supply deal and walked away with a humongous payoff that funded most of current new car development.

Not THAT bad a divorce settlement. Historically though, anyone who has jumped into bed with American car corporations has been dragged down.

Re: FIAT Buys Cadillacís Sigma Platform For Alfa?

Is the word Alp_ha a swear word??? *****, *****, ***** Typical Greeks, always swearing

The GM Alp_ha platform is the/next genration?"of the Sigma platform The Sigma would be a cheaper way to make a RWD 159 and probably cheaper and maybe lighter than using the Premium platform. The Jag platform would only be suitable , at best, for a 169

The Alp_ha project can trace its roots back to Holden's TT36 Torana project of 2004. At that stage, Holden was strongly interested in developing GM's then-idea of a small RWD style platform to go up against BMW's 3 Series range. The company took this concept and worked through GM's parts bin to come away with the end product. Holden borrowed parts and modules from various other GM platforms, the key contributor being its Kappa platform. The Kappa platform's double-A-arm front and rear suspensions provided the basis for the platform's Lower Dominate Structure (LDS). The platform's unique LDS forms its backbone, whilst at the same time providing a stronger, tighter base with which to work with, giving any car which receives the platform a better chance at achieving high-performance goals. By using an LDS, it gives both designers and engineers more flexibility in relation to the design of the upper body of the car, while also maximising space efficiency.

While the TT36 car was displayed with a twin-turbo Alloytec V6 engine, both the car and platform were developed to handle various engines, with smaller 4-cylinder petrol & diesel engines, as well as larger V8 engines, capable of being placed within a car underpinned by the Alp_ha platform. With the addition of certain components, AWD vehicles are a possibility with this platform.

Holden's TT36 concept car was showcased at the 2004 Australian International Motor Show, previewing two key ideas: both design language for the-then upcoming VE Commodore as well as showcasing the potential for a smaller, more affordable, RWD vehicle. Plans failed to move dramatically forward within the next 18 months, but sources of late have indicated that GM has given the green light to the project, with the new platform to underpin a number of new vehicles, the first of which should appear by 2010.

They could do a lot worse. The Cadillac CTS is a cracking car.

I think if they're going for a RWD platform, it won't matter too much which one it is. The Sigma platform sounds like a pretty modern one and it'll only be the starting point.
