Have Saab's engineers done some magic to the 2012 Saab 9-5 engines?

Earlier today I was reading the Swedish price and specifications brochure for the new 2012 Saab 9-5 SportCombi when I noticed that the CO2 emissions were lower than I expected. And so I did a comparison to the 2011 Saab 9-5 Sedan specifications and found that the consumption and emissions figures for the SportCombi were lower than for the Sedan! In the tables below you can find the comparison. All figures are the combined driving cycle figures from the brochures.



First the petrol engines:

	Turbo4 160HP	Turbo4 220HP (incl BioPower)	Turbo4 220HP XWD (incl BioPower)	Turbo6 300HP XWD
2011 Saab 9-5 Sedan
Manual 6-speed
Fuel consumption (litres/100km)	7,8	8,2	8,8
CO2 emissions (g/km)	179	189	203
Automatic 6-speed
Fuel consumption (litres/100km)		9,1	9,9	10,6
CO2 emissions (g/km)		209	228	244
2012 Saab 9-5 SportCombi
Manual 6-speed
Fuel consumption (litres/100km)	7,7	7,8	8,5
CO2 emissions (g/km)	182	185	207
Automatic 6-speed
Fuel consumption (litres/100km)		8,7	9,4	10,1
CO2 emissions (g/km)		206	223	245

Around 5 percent less fuel consumption for all engines in the SportCombi compared to the Sedan!


The diesel engines:

	TiD 160HP	TTiD 190HP	TTiD 190HP XWD
2011 Saab 9-5 Sedan
Manual 6-speed
Fuel consumption (litres/100km)	5,3	6	6,7
CO2 emissions (g/km)	139	159	176
Automatic 6-speed
Fuel consumption (litres/100km)	6,8
CO2 emissions (g/km)	179
2012 Saab 9-5 SportCombi
Manual 6-speed
Fuel consumption (litres/100km)	4,8	5,5	6,6
CO2 emissions (g/km)	143	146	174
Automatic 6-speed
Fuel consumption (litres/100km)	6,6
CO2 emissions (g/km)	175

The SportCombi TiD M6 has almost 10 percent less fuel consumption than the Sedan, but higher emissions. Strange...
The SportCombi TTiD M6 has 8 percent less fuel consumption and emissions than the Sedan.


So have Saab's engineers done some magic to the 2012 engines, or is this just one big misprint after another?
