Wider Engine Choice for Saab's All-new Flagship

Saab
Just three months after its launch, the appeal of the new Saab 9-5 sedan is significantly broadened by the introduction of three new engines, doubling the size of the powertrain menu.
For Model Year 2011, a 190 hp/140 kW, 2.0-liter turbo diesel makes Saab XWD, the widely-acclaimed all-wheel-drive system, available for the first time with compression ignition. Using two-stage turbocharging, this new engine combines strong performance with impressive frugality and joins the current 160 hp/118 kW, single turbo version.
The gasoline line-up is extended by the addition of a highly efficient, 180 hp/132 kW, 1.6-liter turbo, reinforcing Saab's engine rightsizing strategy and establishing a lower price entry point for the range. A 220 hp/162 kW, 2.0-liter BioPower engine - able to run on gasoline and/or E85 fuel (85% bioethanol, 15% gasoline) in any blends - is also introduced.
The Saab 9-5's high-tech options list is expanded by the addition of Adaptive Cruise Control (ACC) and, for the US market, the inclusion of a blind-spot indicator function and remote engine starting. The exterior color palette is also increased from seven to 11 colors.
Greater pulling power with 2.0 TTiD
This more powerful, two-stage turbo diesel engine generates substantial torque of 400 Nm from just 1,750 rpm, in addition to maximum power of 190 hp/140 kW. The result is 80 -120 km/h fifth gear acceleration in just 8.4 seconds and zero to 100 km/h in under nine seconds. Combined cycle fuel consumption of 6.1 l/100 km and CO 2 emissions of 161 g/km are equally impressive.
The sequential, two-stage charging 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 the 'best of both worlds': good, 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 2.0 TTiD engine is available in Linear, Vector and Aero specification and can be specified with Saab XWD, combining diesel power for the first time with this advanced all-wheel-drive system. All variants are equipped as standard with Saab's sophisticated H-arm rear suspension. It uses double isolated sub-frame mountings for greater ride comfort, and also reduces vibration entering the cabin and improves roadholding.
Rightsizing with 1.6 turbo power
This small, highly efficient, 180 hp/132 kW engine epitomizes Saab's rightsizing engine strategy. Developing more than 112 hp per liter, it is among the most powerful series production engines in its displacement class.
Such strong power, backed by plentiful torque of 230 Nm all the way from 2,200 rpm to 5,500 rpm (including an 'overboost' function), enables zero to 100 km/h acceleration in 9.5 seconds. Combined cycle fuel consumption and CO 2 emissions are 7.8 l/100 km and 179 g/km respectively.
Available in Linear and Vector specification, with two-wheel drive only, this engine will establish a lower price entry point for the new Saab 9-5 range.
BioPower choice
The 9-5 sedan now also features Saab's most sophisticated expression of its BioPower flex-fuel engine technology. The new 2.0-liter turbo BioPower engine, like its gasoline-only stablemate, utilizes direct injection and variable valve timing, on both inlet and exhaust sides, to further improve fuel consumption, emissions and performance.
This engine offers the environmental benefits of being able to run on E85 fuel (85% bioethanol, 15% gasoline) and/or gasoline in any blends. In both configurations, it delivers peak power of 220 hp/162 kW and torque of 350 Nm from just 2,500 rpm.
It is available with two-wheel drive and Saab XWD in all model specifications.
Adaptive Cruise Control with Stop & Go for greater driving comfort
This optional feature for models with automatic transmission enables the driver to select a constant cruising speed and automatically alters the chosen speed to maintain a safe gap to the vehicle on the road ahead. F ull distance control is provided from 180 km/h down to a standstill. ACC offers more relaxing and less stressful driving, particularly in slow-moving, congested traffic conditions. T he driver can select one of three distance options.
A radar sensor in the grille emits a beam to measure the distance to the vehicle in front. If this gap reduces below the required setting, the throttle opening is adjusted or engine braking is applied. Once the appropriate distance is restored, the car will accelerate back up to the pre-set speed. Should heavy braking be required, a visual warning is flashed and a gong sounds to alert the driver to take action.
ACC, available later in the model year, requires the fitment of Saab's Pilot HUD head-up display.
For the US market, two additional options are offered: a blind-spot indicator, which flashes a driving warning in the door mirrors, and remote engine starting via the key fob, a useful aid to pre-heat or pre-cool the car's cabin.
