XRAY NT1 2011 Version

At the heart of XRAY’s philosophy is a firm commitment to perfection when it comes to engineering, design, performance and support, all made possible by state-of-the-art in house manufacturing. The NT1 is synonymous with the absolute perfection that is XRAY: a platform that has been capturing trophies at tracks all around the world, and also capturing the hearts & mind of customers who demand nothing less than excellence.

Multiple winner of “Car of the Year” awards and the absolute winner of all major titles – including World Champion, European Champion, USA Champion, Asian Champion and dozens of National champion titles all around the world – proves the unbeatable pedigree of this platform. XRAY brings forth the NT1 2011 edition, the next evolution of the winning platform.

[Martin Hudy, XRAY NT1 Project Designer]

“To improve upon the car that is already the world’s best performing platform and the most successful nitro touring car in the market has been an extremely tough task. During the last few years we have continued year-by-year to introduce new changes and ideas to improve performance, reliability, and handling. For 2011 we focused on what we knew to be missing for a pedigree racing car like the NT1 : a chassis designed to easily accommodate graphite reinforcing inserts or additional balancing weights (front and rear) and one that is easier to perform handling-improving set-up changes on. Enjoy the 2011 NT1 and see you at the tracks.”
