“Does Saab exclusively have direct ignition within GM? I think that is what made their Trionic system (which has since been replaced by Bosch’s Motronic system) so capable of handling the BioPower application.”

No, direct ignition is not a Saab exclusive, although it is a Trionic exclusive. Trionic 8 is currently found on all Saab gasoline engines in 9-3 except the high feature V6 (and the naturally aspiranted 1.8 XE availible in europe). The high feature engine uses Bosch Motronic E9 and the 1.8 uses a system called Simtec.

Direct ignition with Trionic 8 is also no longer in the form of a cassette but with separate ignition coils and a unit called CDM which analyses the ionization current for the ECM. The ionization current is not related to the BioPower function which is handled through lambda sensor inputs. Ionization current replaces conventional knock sensors and phase sensors.

Trionic 8 does not have high voltage ignition drivers, so it can not handle direct injection applications. Nor is it currently availible to control variable cam phasing, something which improve torque over the whole rpm range, reduce fuel consumption and exhaust emissions. Kjell AC Bergström, the boss at GM Powertrain Sweden have however said that they are working on a new engine management system which will be able to control the whole drivetrain in all kinds of GM vehicles, even with hybrid applications, so one can assume that Trionic 8 will be replaced in a not too distant future.

The 9-4X is slated to only be available with the normally-aspirated V6 in the North American market if the rumors are true. We in N.A. won’t be offered the more fuel-efficient (and therefore more desirable, IMHO) 2.0T version even if they do end up putting that engine into the 9-4X.

Also, there will be no excuse for any new Saab vehicles to be equipped with a port injection engine. All new Saabs must have direct injection to not be a laughing stock when even Pontiacs, Saturns, and Opels now have it. The “premium” brand should be given the cutting-edge technology first, not have it trickle-up from the brands lower down the prestige ladder. Talk about mis-managing the brands, GM…

Ooh, I’m excited to see what Swade thought of the Rendezvous. If he liked it, that’s cool, but that’s doubtful. If he didn’t, I can tell him it doesn’t matter, because Enclave.

Sorry to say, the 2.0T will be 220hp as in the Insignia..

SaabKen: Thanks, but there is no confusion. I know that the D.I. you were referring to is “direct injection” (as opposed to port injection, which Saab still uses in ALL of its engines, despite most cutting-edge auto companies having switched to D.I. already). I was changing the subject when I mentioned direct ignition.

Does Saab exclusively have direct ignition within GM? I think that is what made their Trionic system (which has since been replaced by Bosch’s Motronic system) so capable of handling the BioPower application.

Ufff Finally!!!! Comme on!!! I was getting crazy with you guys!

But I was amazed with the amount of people excited about this: that shows that the 9-4 is generating a lot of enthusiasm!!! That’s good!

saab has confirmed that the image above is not the production 9-4X, but rather a creative photoshop of the 9-4X Concept from last year’s Detroit Auto Show produced by third-party reps down in Chile.

AND why oh WHY does not Saab sell Diesels in the US when VW is launcing a Touareg TDi and the New Rabbit as TDi in the US in early 2009?
Imagine.. The 9-4X and the NG 9-5 with the new 250hp 2,9TiD V6… Eh america?

Continuing on the Direct Injection talk..
The Vectra/Omega 2,2 litre (L engine?) i still argue to be an engine to work on and that has been given to little attention. It has been used atleast since 1999 in Opels/Vauxhalls. It´s Direct Injected and has got a timingchain instead of a belt (Saaby).
