Saabs first-ever SUV comes by way of GMs ubiquitous mid-sized SUV. The 9-7X will be offered in two "forms," Linear and Arc. The Linear is powered by the 275 hp Vortec 4200 I-6 whereas the Arc is powered by the Vortec 5300 V8. While the family resemblence is there, the 9-7X is easily the most attractive of the GM mid-size SUVs.
