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. 🙂
