Saab is one manufacturer who was a huge proponent of turbo-charged engines. They were turbocharging since about the 70's on their passenger cars.
Their V6 on the (-3 is available was an assymmetric turbo (which only 1 bank of cylinders is running the turbo)
Still to this day, they stand by turbocharging, from using a Light Pressure turbo for lower models to bigger boost in sportier models. And in some models with automatics, there's an overboost mode when you step on the accelerator pedal in automatics, where you get about 20 seconds of a lot more boost (controlled by the electronic wastegate).
