The Saab 9000 and GM900: Brochures

1995 Saab 9000 and GM900 1 2 3 (4) 5 6

Saab’s most competitive range of engines ever.

No matter which Saab you choose, you get a transverse engine with four or six cylinders, driving the front wheels. It features an advanced management system (Trionic or Motronic), two or four overhead camshafts and four valves per cylinder, which means that each cylinder bene fits from two intake and two exhaust valves for improved breathing and more uniform combus tion. Our four-cylinder engines also have twin balancer shafts to reduce engine vibration to an absolute minimum. (The six-cylinder units are self-balancing by virtue of their cylinder con figuration, so they don’t need balancer shafts.)

The Saab 9000 is now available with a 3.0 litre V6. Like its smaller stablemate, the 2.5 litre V6 in the 900 Series, it is unusually fuel efficient considering its high performance (210 hp/270 Nm and 170 hp/227 Nm respectively). Exhaust emissions are also impressively low.

You don’t have to choose between performance, economy and the environment. With Saab, you get it all

Saab leads the development of high-performance, low-emission engines through a combination of turbocharging, advanced engine management and efficient emission control. As well as a small team of dedicated engineers who, just like their forebears in the aircraft industry, make it a point to seek out new design solutions.

This approach produced innovations such as APC (Automatic Performance Control), Dl (Direct Ignition) and now Trionic, one of the world’s most advanced engine management sys tems. It controls fuel injection and ignition and, on turbocharged engines, boost pressure too.

The brain behind the brawn

The Trionic system has a unique ability to “look into the engine”, to measure exactly what is going on inside the cylinders. We utilise this ability to optimise combustion to increase power, and reduce fuel consumption and exhaust emissions. It allows us to squeeze the maximum benefit from every grade of fuel without engine knocking.

The brain of the Trionic system is a powerful micro-processor which is so fast that it man ages to calculate and fine-tune the injected fuel during each injection pulse.
