Saab is already working on a hybrid version of the new 9-5 sedan. The hybrid version will use a small petrol engine backed up by an electric motor in an effort to increase fuel-economy and cut emissions.
Saab is working on a new 120-hp turbocharged 1.4L gasoline engine that will be assisted during periods of acceleration by an electric motor fitted in between it and the transmission. AutoCar says that the electric motor will offer high levels of torque and will come on when the driver is accelerating.
The big advantage of an electric motor is that it offers high levels of torque from idle. In the Saab the electric motor will come on stream when the driver is pulling away or accelerating.
The new 2010 Saab 9-5 will make its world debut at the 2009 Frankfurt Motor Show next week. It will go on sale in early 2010. Pricing and availability details will be announced closer to launch date.
