Just two months after its European launch, the appeal of the new Saab 9-5 saloon is further broadened by the introduction of two new engines.
For Model Year 2011, a 190hp, 2.0-liter twin-turbo diesel will be available with Saab XWD; the first time Saab has combined all-wheel-drive with a diesel engine. Using twin turbochargers, the new engine combines strong performance with impressive fuel efficiency and joins the current 160hp, 2.0-liter single turbo diesel engine.
The gasoline line-up is extended by the addition of an efficient, 180hp, 1.6-liter turbo.
The Saab 9-5's high-tech options list is expanded by the addition of Adaptive Cruise Control (ACC) and an exterior paint color palette that is increased from seven to 11 colors.
The new, more powerful, twin-turbo diesel engine generates substantial torque of 295 lb-ft from just 1750 rpm, in addition to maximum power of 190hp. The result is 0-62mph in under nine seconds. Projected combined cycle fuel consumption of 39.2mpg US and CO2 emissions of 159g/km are equally impressive.
The sequential, twin turbocharging system uses two turbochargers of different sizes with by-pass valves that direct the exhaust gas stream between the two turbines. At low engine speeds, the small turbocharger supplies boost pressure independent of engine load. At intermediate engine speeds under higher loads, both the small and large turbochargers provide boost pressure; while at high engine speeds and load, only the large turbocharger is engaged.
This arrangement provides the driver with instant torque at low engine speeds - via the low-inertia small turbo - and strong, top-end power at higher engine speeds when the large turbo is engaged.
The 2.0TTiD engine is available in Europe in the Vector SE and Aero specification and can be specified with cross wheel drive (XWD), combining diesel power for the first time with Saab's advanced all-wheel-drive system. All variants are equipped as standard with Saab's sophisticated linked H-arm rear suspension system. This system uses double isolated subframe mountings for greater ride comfort, and also reduces vibration entering the cabin and further improves roadholding.
The small, highly efficient, 180hp 1.6T gasoline turbo engine epitomizes Saab's rightsizing engine strategy. Developing more than 112hp per liter, it is among the most powerful production engines in its displacement class.
Such strong power, backed by plentiful torque of 170 lb-ft from 2200rpm to 5500rpm (including an 'overboost' function), enables 0-62mph acceleration in 9.5 seconds. Combined cycle fuel consumption and CO2 emissions are 30mpg US and 179 g/km respectively.
The 1.6T is available in Vector SE specification with front-wheel drive and manual transmission.
