If, like many of us, you've fallen for the idea of a track car designed by motorbike-maker KTM, and engined by Audi, there's good news. Object of our affections, the X-Bow, is to be built in much higher volumes than it was planned when we saw the car at the Geneva motor show.The Austrian motorbike maker announced yesterday that it has signed a letter of intent with manufacturing specialists Magna Steyr to put the X-Bow into proper series production at Magna's factory in Graz, Austria. Previously, development partner Dallara were in the frame to produce an introductory run of 100 cars only; potentially, Magna could make as many as 1000 X-Bows a year for KTM. In other words, if you’d been told that there was no possibility of getting hold of one of the outlandish-looking track cars, it may be worth another enquiry.Production of the car will begin in February 2008 if all goes according to plan. The company currently has around 600 orders, which it expect to be able to deliver on by early 2009.
