2012 Saab 9-5 SportCombi: More photos +video

Saab 9-5 SportCombi - Debuts at Geneva It’s good to see Saab suddenly bursting in to life. We’re sure Saab don’t see it that way, having no doubt slaved away for the last year to get business back to some sense of normality after the GM sale debacle, but from outside that’s how it seems.

Concept Car of the Week: Mazda RX500 (1970)

Developed by the Toyo Kogyo Company's advanced design and engineering team, the Mazda RX-500 was described as a ‘mobile test bed for high-speed safety'. Looking at its design, the team's childlike enthusiasm has shone through, resulting in a very cool concept.  From the rakish front to the wraparound windscreen and on to the bread van rear, everything communicates high-tech and ‘70's futurism while also channeling a little of the Star Wars X-Wing. Thanks to plastic body panels, the concept weighs only 850kg and is powered by a 491cc rotary engine delivering 247bhp fitted behind the cabin, in front of the rear axle.
