At this week's Chicago Auto Show, Nissan not only revealed the highly unconventional GT-R LM Nismo Le Mans racer but also showcased the 370Z Nismo Roadster Concept. As the name suggests, the high performance machine is still a pre-production prototype but it would highly surprise us if the 350 bhp Nismo Roadster will not be available to customers shortly.
Among the other cars released in the windy city were the Kia Trail'Ster Concept and the Mitsubishi GC PHEV Concept.
Also in Chicago, Mercedes-AMG offered a first glimpse of the Mercedes-AMG GT3, which will be revealed at next month's Geneva Motor Show. Another new GT racer that broke cover this week is the Reiter Engineering developed KTM X-Bow GTR. Due to race in the GT4 category, it is the first fixed-head KTM X-Bow.
At Retromobile we were treated to this very rare Bugatti Type 50 Paul Nee Roadster. It features a body, which followed the 'standard' design by Jean Bugatti but not built by Gangloff as was normally the case but by little known French carrossier Paul Nee. Several years later, he also clothed this Bugatti Type 57. This Pillarless Coupe design was penned by Fernandez & Darrin and featured a large sliding roof and prominent chrome trim.
