Aerodynamic bodywork with exposed buttresses was also used above the rear engine cover.

Racing History

The Japanese Grand Prix was called off for the year 1965 as a result of which Prince started utilizing the R380 to test the high speed aerodynamics. This eventually enabled the car to break five E-class land speed records in later half of 1965.

Once Nissan took the authority to rebuild the R380, four R380s were entered in the Japanese Grand Prix for another time. However, this time Porsche 906s took the lead and won the title by the difference of 2 minutes, while the R380s secured second, third, fourth and sixth place. In later years, Nissan R380-II set new land speed records and broke seven records in just one year.

In 1968, Nissan introduced a newer version called the R381. The sales of the R380 were then limited to the privateers. Three of the new R381 once again entered in the Japanese Grand Prix and stood third, fourth and fifth. In the 1969 Chevron Paradise 6 Hour race at the Surfers Paradise International Raceway in Australia, Two Factory entered with R380s which took first and second places. R380 continued to perform well in races as it took second place in the 1000 km of Fuji race in 1969 followed by another second place victory an year later in 200 mile (320 km) race at Fuji.

Nismo restored an R380-II vehicle in 2005 and displayed it in many events with certain other vehicles of its series.
