The Saab 9-4X concept provides a look at a future product for Saab. Although Saab has shown numerous creative concepts over the last several years, it has had little to show in terms of production models. The compact crossover 9-4X is a product that Saab needs to compete in a rapidly expanding market segment. The concept is powered by a turbocharged four-cylinder engine that runs on Gasoline and/or Ethanol.
