This was the peak of Nissan fuel economy, at least in a regular size (over 660 cc) car.
The introduction of 5-speeds, per the Datsun Service Bulletin was "1976 1/2". All the 5-speed B210s were the big heavy 63A model. Which is ironic because they were all fitted to lo-po A14s. Apparently Nissan had no smaller 5-speeds to handle the torque of A14, so it was converted to A-series use just after the fuel crisis.
From the same engineers who brought you the Z-car.
