The Swedish edition of Auto Motor Sport tested the Saab 9-3 TTID sedan. It is the new 180 PS version with a CO2 emission of 119 g / km, which can also be found in the SportCombi
The driving impressions and the difficult history of development, what the Swedish version of the Auto Motor Sport writes, translated by us in excerpts:
It's like the old story of the bumblebee who doesn't know it can't fly. What luck for the bumblebee, because otherwise she would have to walk home.
Something similar is the story with Saab and the idiosyncratic Saab engineers. Because if those had belonged to your Opel colleagues, this car would not exist.
We drive from the airport Landvetter past the university on the highway. It seems that Saab has changed the gear, the top sixth gear is a pure overdrive. At the speed of 110 Km, the tachometer displays modest 1.750 revolutions. No problem, we have enough power reserves at 400 NM.
A small drop of sadness remains, the "green TTID" does not create the same driving sensations as the old AERO TTID, which we drove in 2007. But it had CO2 emissions of 154 g / km and a consumption of 6.4 liters. The AERO TTID was optimized in spring 2009 to 5.4 liters and 141 g CO2 per kilometer.
To make the leap from 141 to 119 g CO2 while maintaining the original peak performance does not seem possible.
When other car manufacturers want to push their environmental diesel below the magical 120 g limit, smaller engines with more modest output are used. For example VW Passat TDI BlueMotion (105 PS), Volvo V70 DRIVe (109 PS), Audi A4 2.0 TDI (136 PS) and the Ford Focus ECOnetic TDCi (109 PS). Only Saab partner BMW creates an optimized environmental diesel with high performance with the 320 d.
Saab would have had the opportunity to install the 1.7 liter Opel Eco Flex Diesel with 110 PS and 260 NM in the 9-3 to achieve the environmental goals, but that, according to Magnus Hansson of Saab, was never an issue.
“In 2007 we knew about this limit value for many European countries and saw the possibility of reaching it. So we went to Opel in Rüsselsheim to apply for development funds, ”said Magnus Hansson. But the application was denied.
So it was the Saab people also 2008 and overall, the application was denied four times. At the last refusal the Opel development chief told the Saab people that this engine in the Saab 9-3 can never be got under 140 g Co2 per kilometer.
The Saab people drove home to Trollhättan and started the project anyway. From summer 2008, the project "119 grams" was worked on. And when the decision to close the plant was made on December 18, 2009, it was decided to continue working and bring the "119 grams" project to an end. Because it was clear to everyone that this project could save Saab.
We worked across the board, says Thomas Cam from the development team. The weight has been reduced (- 50 Kg), improved aerodynamics, optimized injection, less roll resistance. Everything was put to the test, even the power consumption.
Meanwhile, the 9-3 180 PS SportCombi is under the magical 120 g / km limit. The engine is our first choice and buy recommendation for the Saab 9-3 Griffin Model series. Thanks to incredible fine work by the idiosyncratic Saab engineers. What the ex colleagues from Rüsselsheim said about the flying bumblebees from Trollhättan is not known.
