Saab will unveil a new 'Sport-Hatch' concept car claimed to challenge the distinction between traditional hatchback and wagon body styles at next month's Frankfurt motor show. This latest concept - Saab seems to manage one per European motor show - is a sporty, five-door, four-seat car said to offer driver-focused performance and innovative versatility features, all packaged in a 'fastback' shape that draws its inspiration from the Saab 9-3X 'cross-over coupe' concept first seen last year.
