| The Nissan 680 was introduced in March
1959, and was an all new design from the ground up.
The 680 marked a big step up in design
from the previous Nissan 580 series. The new truck featured bold and very
modern styling for it's time. The broad flat front area of the truck had
quad headlights, which were becoming fashionable on passenger cars from
that era. The headlights on the 680 had the lights stacked vertically,
with one on top of the other. The grille consisted of a large rectangular
opening with an odd looking protruding grille that was quite short, and
left a large gap at the top and bottom of the opening. The grille was a
one piece white painted pressed steel design, with the top bar significantly
wider than the bottom one. A large chrome and red Nissan badge was attached
to the grille. Above the grille there was another air intake, this opening
featured a white painted strip with a raised section in the middle with
680 stamped into it.
Mechanically the 680 was very different
to the previous model. The 680 was fitted with the all new Nissan P series
engine, which was an overhead valve 3956cc 6 cylinder engine that produced
125hp. The 680 also had a new 5 speed gearbox. The chassis was 200mm longer
than the 580, and a long wheel base model was also built. A bus version
was introduced in September 1959, and it was designated the Nissan 690.
In 1965 the P series engine was upgraded to produce 145hp. At this time
there was a change to the grille design. The 1965 model uses the same grille
as the 1959 model, but it no longer has the chrome and red Nissan badge.
The air intake above the grille now has a taller white painted strip, which
now has Nissan stapmed on it.
In 1968 Nissan released the new Nissan 681. The 681 continued to use the
145hp P series engine, but had a new front end styling. The new 681 has
a full width grille that now incorporates the headlight surrounds. The
681 continues to use quad headlights, but they are now arranged side by
side rather than one on top of the other.
The Nissan 681 was in production until
June 1969, when it was repleced by the Nissan 780.
