Some answers to questions on the 2010 Saab 9-5

I receive every comment that comes through this site via email. Consequently, I get a feel for who’s who, who knows what’s going on and who likes a good theory.
One person I’ve come to the highest respect for in terms of real-world knowledge about the products Saab are dealing with is a commenter named “Saabjohan”. I haven’t had any communication with Saabjohan personally, but I can tell from the depth of knowledge he displays whenever he chimes in here that he most likely works pretty closely with the cars we all know and love.
Saabjohan has just left a comment on the My 2 cents article and it’s a comment that addresses some of the questions and doubts expressed by other commenters in that thread.
As I read it, I figured it would be good to move it here to the front page for everyone to see.
I don’t have time to dig up the questions/comments he’s responding to, but I have a feeling they should be pretty self explanatory from the answers anyway.
My thanks to Saabjohan for his time and expertise.
Quijote: Keep in mind that Saab lists the 0-62 mph times, not 0-60 times as Cadillac does. I would also expect the numbers to be on the conservative side, and if you actually run a 9-3 Viggen or an old 9-5 Aero against the new 9-5 Aero with the 300 hp V6 the latter would most likely provide the quickest acceleration in most situations. However, I
don’t know why they have not selected the 325 hp version instead of this 300 hp vesion of that engine. They are most likely almost identical, perhaps the 325 hp version can’t pass emissions for sale on the US market?
As for the Cadillac, it does use a direct injected engine with dual cam phasing something GM still haven’t offered on turbocharged versions. Also, as already have been mentioned, you can’t compare US fuel economy numbers with EU numbers.
raquettelaker2: Why not dig up the old Saab V4 engine too? No seriously, the old B235 is today outdated, it does not have the features you want and need in a modern car engine, and the development work required to update it to a more modern standard, well, it’s not worth it.
Markac: General Motors does not have any 2.2 to 2.4 litre engines that are adapted for turbocharging. The engines that they have in this range are essentially larger capacity versions of the same 2 litre engine found in the new 9-5, and the current 9-3, but without the reinforcements required for turbocharging. The most powerful four cylinder engine GM currently have is the 2.0 litre LNF engine which produce 260 hp, an engine that also feature direct injection and variable cam phasing on both the inlet and exhaust cam. If there was any GM four cylinder engine that is missing in the current engine line
up in 9-5, that’s the one. Imagine a BioPower version of that engine!
Börjesson: The emissions from the 1.6T 180 hp version are very similar to the 170 hp Audi A6, the A6 is a few g/km better, but on the other hand the diesel with it’s 160 hp is quite a bit better than comparable Audi A6 and Audi have no trouble selling these because they are large or consume a lot of fuel. Opel Insignia have also sold quite well in Europe using basically the same engines that Saab is using.
As for a more powerful engine, a lot of people may want a more powerful engine, but not that many actually buy them. In the United States, Audi does for instance only offer one of it’s A6 models with more power, that’s the 350 hp version. But if Saab can introduce the 325 hp engine they are not far behind in terms of power. If you want a more powerful Audi than that you have to buy an S6 and due to their much higher price, they don’t sell in the same type of numbers, and if only say 5% of the customers want such a model and the 9-5 sells 50,000 cars a year you would be forced to share the development costs of those cars over just 2500 vehicles a year. In other words, it’s unlikely that an S6 competitor would pay off.
Sarah: No, Opel engineers was not responsible for the design, but Saab had during the time this car was designed their design office in Germany at the same location as the Opel design office where the head of design was responsible for both Opel and Saab. The Audi A6 was probably a benchmark, but not in terms of design.
