Apparently the 2.0 turbo is a derivative of the 190hp Opel > engine uses in the Astra coupe. The 2.0 liter engine in the current 9-3 and 9-5 has no relations with Opel. It can trace its roots to the 2.0 liter engine Saab designed in the early 1970:ies for the Saab 99 with a major redesign when the 2.3 liter engine (with balance shafts) were introduced in 1993. The engine in the new Saab 9-3 2.0 is based on GM's L850 global four-cylinder family designed by Lotus. The engine block is also used by Opel for the Vectra (with 2.2 liter), but the cylinder head is unique to Saab and the internal parts are not the same as used by Opel. > Same for the platform.

It is the Vectra that is based on the new Saab 9-3 platform. :-) The new 9-3 is based on a platform jointly developed by GM to be used for several cars from several GM companies (Saab 9-3, Opel Vectra, next Saturn L-series, Chevrolet Malibu, Pontiac Grand Am). It can not be said that the platform is "the Opel Vectra platform" or "the Saturn L-series platform", it is the "GM Epsilon platform". The Epsilon platform is flexible and can easily be used for cars with different front wheel cars of various lengths and widths. > Just remember that the > 9-5 also uses a platform which is based on the Opel Vectra. I, at > least, do not see that many simularities when I compare a 9-5 to a > Vectra. The new 900 and the current 9-3 was based on the Vectra A chassis. This chassis was not new when the new 900 was designed, but it was available. The 9-5 was based on a heavily modified Vectra B chassis. This chassis was new when the 9-5 was designed, but it had to be heavily modified for the larger 9-5. The new 9-3 is based on the new global GM Epsilon platform. -- G–ran Larsson http://www.nospam.com
