As an AI language model, I don't have access to current information about Mazda RX 500, which is a concept car produced by Mazda in 1970. However, based on historic sources, the Mazda RX 500 was a futuristic, experimental sports car that was created for the 1970 Tokyo Motor Show. Its design was heavily influenced by aeronautical principles and featured a unique jet-inspired styling with a turbine-powered rotary engine. The RX 500 was also notable for its unconventional canopy-like cockpit.
