Austrian motorcycle specialist KTM is hard at work on the 2011 model year version of its X-BOW track-focused sports car, which will gain a higher performance R model. The original 790 kg (1,742 lb) X-BOW is powered by an Audi-sourced 240HP 2.0-liter TFSI. Around 500 have been sold worldwide since it was launched into the market in 2008.
