Saab 9-X BioPower Air and hybridization

The Saab 9-X Air has a very high engine performance combining rightsizing (optimization of the engine), overeating, use of bioethanol and hybridization. The set allows sports performance with low environmental impact.

Optimized for E85 (85% bioethanol, 15% gasoline), the small turbo BioPower engine delivers the 1.4 liter power of 200 kW ch/147 with a couple even more amazing 280 Nm multiple engine fuel, it enjoys outside of rightsizing, the assistance of a hybrid technology, which should give it gasoline consumption in combined cycle of only 5.0 l/100 km with 119 gCO2/km. In the E85, CO2 emissions should be even lower and limited to 107 g / km, with a consumption of 6.5 l/00 km.

Coupled to a six-speed manual reports with an automatic clutch and Pallet driving, this advanced powertrain has been designed to meet the environmental priorities and energy required to use a car today.

An optimized BioPower

Saab already dominates the emerging market for flex-fuel vehicles with its current BioPower models, which offer more power with E85 than gasoline while rejecting less CO2 fossil fuels.

The Saab 9-X Air grows here this technology even further by using an engine that fully exploits the benefits of high octane of E85. It operates at a compression ratio (10.2 to 1) and a boost pressure (1.6 bar) greater than would be possible with only an engine fueled with gasoline. One possibility allowed by the higher octane of E85 (104 RON) than gasoline (95 RON), which makes it less sensitive to auto-destructive so-called "ping", which can appear when the compression of the air / fuel into the cylinder.

In operating on E85, the BioPower engine light but offers a sophisticated power worthy of a cylinder engine much more important. The spectacular torque of 280 Nm, for example, is available of 1,750 rpm to 5,000 rpm. This is again proof of the validity of rightsizing policy Saab: offering exceptional power without the weight, size, consumption and emissions associated with an engine displacement of air greater.

If it is optimized for E85, the engine retains all its flex-fuel capability and can still run on petrol, although in this case it does not deliver the same power. The engine system is able to adjust the ignition point and reduce pressure turbo to avoid auto caused by the compression ratio higher.

The technical sophistication of this engine has also adopt direct injection DI (Direct Injection), with injectors arranged in the center of the room and a continuously variable valve timing VVT (Variable Valve Timing), both admission and exhaust. The result is more torque at low revs and sobriety even greater.

GM Hybrid System new generation

Consumption and CO2 emissions are reduced by the arrival of the GM Hybrid system last generation, to recover more energy and providing electric significantly larger than the current GM Hybrid system. A alterno-starter, led belt by the engine crankshaft, replaces the conventional alternator. Electrical power is delivered and stored in the lithium-ion battery compact housed under the floor.

During starts since a complete halt or overtaking maneuvers, the engine makes its power acceleration. It also serves as the basis for stop / start automatic, which occurs when the car is stationary to reduce consumption. To further improve the simplicity, the hybrid system provides a longer cut of food during phases of deceleration or braking.

The electric motor can also act as a generator. It can be driven by the engine to charge the battery and meet the electricity demands of the vehicle. Or it can also be used to recover the kinetic energy deceleration, storing energy in the battery. A sophisticated electronic manages the conversion AC / continuous and all power supplies, including a 12-volt in the cabin.

The combination of GM Hybrid Systems and Saab BioPower this important synergies. The hybrid system adds the power of acceleration and, specifically, improves response to the accelerator. Thus further reducing the size of the engine with additional benefits in terms of consumption. The rightsizing and hybridization are complementary, and have more advantage when they are than either drug alone.

Apart from fuel and energy, responsible performance also high standards of safety. In addition to the full arsenal of electronic aids to conduct stability control and braking system, active safety still progressing through the alert function drift LDW (Lane Departure Warning). A camera ready at the front scans the road which runs in front of the car, and warning messages are sent on the information screen the driver if the car away from markings on the ground. The same camera is also used to detect light sources when it is night. Small parts are automatically obscure the beam headlamps when a car arrives in front. To improve the protection of occupants of retractable hoops are mounted behind the rear seats.
