Class-leading CO₂ emissions of 119 g/km are on offer within the latest Saab 9-3 range, which benefits from an across-the-board emissions reduction of 10 percent, making this car a perfect choice for company car users, and a cost-effective option for customers keen to reduce fuel consumption and their carbon footprint.

For Model Year 2011, all 9-3 diesel engines have more advanced twin turbocharged engines and, in the saloon, all three engines give CO₂ emissions of just 119g/km and exceptionally low combined cycle fuel consumption of 62.8mpg.  The most powerful variant, the 178bhp 1.9 TTiD, now delivers the most efficient performance for a four cylinder diesel engine in the marketplace in terms of CO₂ per unit of horsepower.

Saab engineers have delivered class-leading diesel performance following an 18-month development program which focused on achieving an average 12 percent reduction in fuel consumption and CO₂ emissions. For saloon models, the result is emissions below 120g/km, a key vehicle taxation threshold in the UK market, and the cleanest and most efficient Saab ever.

By introducing twin turbochargers across the diesel range, Saab engineers have optimised the engines to harness more power and torque in the interests of fuel consumption and lower emissions. The 1.9-litre diesel line-up now comprises a 128bhp TTiD unit (replacing the previous 118bhp TiD engine), a 158bhp version (replacing the 148bhp TiD engine) and a range-topping 178bhp/295lb ft variant.

With these engines and manual transmission, the 9-3 saloon delivers outstanding combined cycle fuel economy of 62.8mpg and 119g/km CO₂ emissions, and is tax-exempt for vehicle excise duty. The SportWagon offers an impressive 61.4mpg and low CO₂ emissions of 122g/km and for the Convertible, the respective figures are 54.3mpg and 137g/km.

To dip under the 120 g/km level, optimised gearing is fitted without affecting acceleration or top speed.

Other efficiency measures introduced include:

• Recalibrated engine management with improved fuel injection and combustion control
• Revised gear ratios to match new power and torque characteristics
• Improved electrical power management, including sophisticated alternator control when battery charging is not required and more efficient electro-hydraulic power steering assistance
• Low rolling resistance tires for reduced road friction
• Improved aerodynamics, with rear underbody deflector blades
• Reduced weight through lighter construction and sound-deadening materials
• Revised torque converter for automatic transmission with  optimised shift programming.

The all-turbo petrol line-up, which features an average reduction in fuel consumption and CO₂ emissions of 7 percent, also benefits from some of these measures.

In addition to the significant powertrain improvements, standard equipment levels have been increased for MY11.  All 9-3 models now come with Bluetooth phone integration and heated front seats as standard.  Other model year enhancements include the introduction of a ‘change-up’ indicator in the instrument cluster to encourage economical driving; a clutch interlock system on manual transmissions; child seat top tether anchorage points and a perforated leather sport steering wheel on Aero models.  Two new exterior paint colours have been added to the range – Diamond Silver and Java and rear engine badging has been changed to follow the same style as used on the new 9-5 saloon.
