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.

Powered by a high performance 250 bhp, 2.0-liter turbo engine, the 9-3 Sport-Hatch Concept signifies Saab's intention to enter the mid-size wagon segment with a sporty product that reflects the GM unit's tradition for designing versatile 5-door models.

The concept team, under executive director of design Michael Mauer, has expanded a number of exterior and interior design themes from the 9-3X concept car.

"We have promised the largest product offensive in our history," said Saab CEO Peter Augustsson, "and with all the products that we've shown in the last two years, it's obvious that we're keeping that promise. This concept car isn't just a show car. It demonstrates our intent to continue to evolve and expand the 9-3 model line."
