The Austrian firm has priced the X-Bow Race at €82.900 ($105,000 with the current exchange rates) ex-works and excluding national taxes, with first customer deliveries scheduled to begin in January 2009.
Changes on the X-Bow Race model, which like its street-legal sibling is powered by Audi's 2.0-liter TFSI engine delivering an output of 240HP, include race-spec suspension and brake systems, Kevlar-reinforced side panels, carbon fiber windscreen extension for telemetry equipment installation, racing fuel system with quick-fill compatibility and an extended rear bumper that prevents tangling and minimizes spray in wet track conditions. Customers with a bigger allowance may also choose from a variety of optional "PowerParts" like such as the carbon-fiber tonneau cover and Kevlar-strengthened front panels.
The mid-engined sports car can accelerate from 0 to 100 km/h (62 mph) in 3.9 seconds and to 160 km/h (100 mph) in 8.5 sec while its top speed is 220 km/h or 137 mph
The Austrian manufacturer says that the X-Bow 'Race' is extremely easy to maintain and offers significantly lower running costs than competitor cars. To put that in numbers, KTM claims that taking into account all 'wear and tear' parts, tires and fuel, the typical cost of running a X-Bow in GT4 come to about €3,000 (about $3,800) per race.

But in the fantasy land of designers, there are no restrictions or limits, only a desire to create. And for Dutch designer Sabino Leerentveld, who we came to know through his Aston Martin V12 and BMW Nazca Homage prototypes, the answer to the previous question is the Kawasaki ZX-770R Concept.
