"We will show an interesting concept in Geneva that will have the DNA of our Sonett sports car that we sold in the mid-'60s," Kinell told Automotive News Europe at the launch of the face-lifted 9-5 in Spain.
A decision to build the car hinges on public reaction when the concept vehicle is shown at auto shows in the United States next year.
Kinell also confirmed that Saab is developing a small SUV similar in size to the BMW X3. The SUV will be called the 9-4X and will be developed on a vehicle architecture shared with a small Cadillac SUV.
"It will be a worldwide car, but we have to have the right engines for it" such as a diesel, Kinell said.
The timetable for the 9-4X was not disclosed, but industry sources expect sales to begin in 2009.
The 9-4X project follows the cancellation of plans for a Saab version of the Subaru B9 Tribeca. That project was killed after Saab parent General Motors last month sold its 20 percent stake in Fuji Heavy Industries Ltd., parent company of Subaru.
