Saab's most popular 9-3 diesel models now offer reduced CO2 emissions and improved fuel consumption.

Linear and Vector specification Sport Sedans, powered by the 150 hp/110 kW, single turbo or the 180 hp/132 kW, two-stage turbo 1.9-liter engine, now produce just 139 gm/km CO2 and impressive fuel consumption of 5.3 l/100 km over the combined cycle. The SportCombi's figures are also improved, to 144 gm/km and 5.5 l/100 km.

In terms of CO2 grams per horsepower, the two-stage turbo models (badged 1.9TTiD) are now among the top performers in their class.

The efficiency gains, averaging 7 percent, have been achieved by a series of fine-tuning measures including: the use of wider gear ratios, a longer final drive, idle and low engine speed remapping, and an optimized tire and wheel choice. Zero to 100 km/h acceleration is unchanged, while fifth gear 80-120 km/h times are increased by less than one second.

The new variants are available only with manual transmission. In many European markets, the CO2 reductions also provide valuable tax-related benefits for customers.
