From Nissan press:
1970 Nissan R383 - 1970 Japan GP model: Having won the 1969 Japan GP with the R382, Nissan began preparations for a new machine to compete in the 1970 Japan GP. The result was the R383, dubbed "700ps!" Unfortunately, the 1970 Japan GP was cancelled and the R383, without a chance to demonstrate its prodigious ability, became a machine of legend. This commemorative car is a reconstruction (replica) used for motor shows.
