Along with presentation of the tweaked 2011MY 9-3, Saab today also announced that it is broadening the appeal of the freshly launched 9-5 sedan with the introduction of three new engine options, including a 1.6-liter turbocharged petrol, a 2.0-liter turbo diesel and a 2.0-liter turbo BioPower flex-fuel unit, which double the size of the premium saloon’s powertrain menu.

The new 2.0-liter TTiD two-stage turbo diesel engine produces 190HP and 400Nm (295 lb-ft) from 1,750 rpm, and can be specified with XWD, making it the first Saab diesel model to be offered with the Swedish firm’s all-wheel-drive system.

Saab said the diesel-powered 9-5 accelerates from 0 to 100km/h (62mph) in under nine seconds, while returning a projected combined cycle fuel consumption of 6.0 lt/100 km (39.2mpg US or 47.1 mpg UK) and CO2 emissions of 159 g/km.

The 9-5’s gasoline line-up is extended by the addition of a smaller displacement 1.6-liter turbocharged four-banger churning out 180HP and 230Nm (169.6 lb-ft) of torque from 2,200 rpm to 5,500 rpm. Combined fuel consumption and CO2 emissions are 7.8 lt/100 km (30.2mpg US or 36.2mpg UK) and 179 g/km respectively.

Finally, there’s a new 2.0-liter turbo BioPower engine that is able to run on gasoline and/or E85 fuel (85% bioethanol, 15% gasoline) in any blends. According to Saab, it delivers an output of 220HP and 350Nm (258 lb-ft) of peak torque regardless of the fuel type or mixture. The BioPower model is available with two-wheel drive or XWD in all model specifications.
