The engine that might be

The current TTiD engine used in the Saab 9-5 was/is (from my POV) a little bit of a take it or leave it case. After all, Saab was in need of a more powerful engine than the 160hp TiD engine after GM cancelled the Diesel V6.

My own Djup Strupe told me back then that it was strange that Saab was offering that engine as Opel would wait at least one more year for it. The reason was not that the engine wasn’t ready for the market, but the guys at Opel thought that the TiD160 and the TtiD190 had too similar power values and torque values (350/380 vs. 400).

I have never driven a 9-5 Diesel, so I can’t tell if there is a big or small difference between both, but at least until now Saab was the only brand using that engine. Perhaps this was also a (the) reason why there was no automatic available.

Now, for the MY12, Opel is offering that engine on the Insignia. First of all I have to say that there is almost no difference between this version and the units mounted in a Saab. Max Power is 195hp vs 190hp and the max torque stays unchanged at 400Nm (295 lb ft) but only available at 2.000 rpm vs. 1.750 rpm on the Saab.

I don’t know if this makes the big difference the engineers at Opel where waiting for, but the guys at Opel must know why they have waited an extra year.

And why I am talking about this engine if it is not different from the Saab used version? Well, on the one side Opel is using a Start/stop system on that engine in combination with the manual gearbox as either FWD or AWD and Opel also offers an automatic transmission also with either FWD or AWD.

So, if Saab also uses those updated parts, it will first be able to offer the TTiD engine coupled with an automatic transmission, what many here at SU seems to be interested in. And with the manual transmission the Saab could be on par with BMW and Audi regarding the CO2 values, if the Saab is only as good as the Opel, but I don’t think the Trolls want to only be as good as. 🙂

Anyway, good to hear that engine development at Opel / GM continues. The competition does not sleep either.


Was this one the engine that never happened?
Can’t these people get anything right… (sorry). How about selling the engine to Saab or was this the one they turned down?

I promise to wear a ‘I love GM’ t-shirt for a month next summer if Saab is still alive. I hope it’s not taken as a threat 😉

Huh? The 160 Bhp dieselengine, is the same base-engine as used by Opel and Alfa, just as long as Saab has! The 130, 150, 160, 180, 190 Bhp engines are alle based on the engine originally developed by Alfa!

1.9 Twin Turbo Engine cover of Lancia Delta´s 1.9 TT Multijet. Fiat Powertrain Technologies released information about new twin stage turbo (twin turbo) version of this engine in summer 2007, engine is available with two power levels, first one is producing 180 PS (132 kW; 178 hp) and second one 190 PS (140 kW; 187 hp), both have a maximum torque output of 400 N·m (295 lb·ft) at 2000 rpm. 180 PS version production started summer 2007. The engine weighs approximately 185 kilograms (410 lb). This engine will be sold both to Fiat Group Automobiles and other brands, but the… Read more »

900 classic cab

I’ve driven the 9-5 with the 190hp TTiD engine with a manual gearbox earlier this year and although it was just for a few kilometers I must say I liked it a lot. It has more than enough power and torque to accelerate quite well such a big car. At the time I thought it behaved like an upgraded Hirsch TiD with 175hp on a 9-3.


Same impression from a full day driving as yours. The only negative point is the engine is getting loud when fully accelerated. Maybe there are ways to tackle that as well.


Pang Qinghua confirmed on Nov.28 that their new proposal was rejected by GM

I must be missing something here. I drive an 07 9-5 with 150 bhp TTiDengine mated to an auto gearbox. Apparently it doesn’t exist. Help. BTW the engine noise is reasonable, and far overpowered by road noise from the Continental SportContact tyres.


How much economy does the start-stop system give? I’ve read in Dagens Industri that Volvo’s version had no positive effect in fuel consumption.
Do we, as consumers, want to pay for something that adds weight to the car and is just a marketing trick? Besides the cost of it.
That providing that was right about Volvo’s start-stop system. Does anybody here has some first hand experience?


I have posted this link before, and I’ll post it again. Mostly because I am a bit disappointed at this point. I believed start/stop systems were brilliant, but in reality… “You will save a dollar per year with ‘start/stop'” Most of my driving takes place on the open road. If I am stopping for more than 15 seconds I switch off the engines myself. I don’t really know what I envisioned when I first heard about start/stop, but certainly not this. I think my mistake was that I did not realize rolling down a hill will keep the engine… Read more »


I have a 2011 Volvo S60 T4 manual sedan (132kW) with the start-system (Drive) and apart from startling you when restarting after a certain interval if the electronics figures out that you were standing far too long queuing at a traffic light, it does reduce fuel consumption in the city (I have the figures, both manual and based on a Garming eco-route challenge) to back this up. Besides, it reduces CO2 emissions as the vehicle does not continue idling unabated for broader periods of time, again based on measured values using a Garmin eco-route challenge. By the way, buying the… Read more »


Just one small note: GM never cancelled the diesel V6 as the engine was not a GM design. That engine can be bought from VM Motori.


Wasn’t there a limitation because of the max. torque of the gear box?


This may not be totally relevant, If it’s the same TTiD engine in the 9-5 that’s in my 9-3, it’s a storming one. Mine has had the Hirsch 200 upgrade and it really is amazing to drive, I test drove the BMW 320d and also a Lexus 220d, neither had the sort of smooth power the SAAB had, and with the Hirsch, the pull doesn’t seem to stop either. I’d have loved this engine twinned with an Auto gearbox, but with CO2 remaining low at 119, and fuel efficiency good at around 45mpg day to day, I can’t really fault… Read more »
