Historic Information - Identifying Model Years
The differences between model years is very slight, and I usually
differentiate them by their "bonnet" (hood). The early
81s have the fuel filler flap, while the later 81s have no filler
flap but still have the "crease" that runs longways
down the bonnet on either side. The 82s have a totally flat hood
as do the 83s. Many 83s have the "DeLorean" lettering
on the bonnet. I think the angled tailpipes are primarily on the
83s. These hard/fast rules do not always apply as in practice it
is apparent that some intermixing of features has occurred.
Most of the updates were made during production of the cars and
not "aligned" on model year boundaries. It is therefore
difficult to distinguish model years in the traditional "Detroit"
sense. You can either think of the car as having a single model
year (produced for 2 years) with numerous production fixes,
or you can take note of the updates made up to a particular model
year.
Minimizing model year changes was one of the aspects involved
in producing the "ethical" sports car. John Z. felt that a lot of
the model year changes were introduced not as genuine improvements
to a car, but as styling changes intended to make previous models
obsolete.
The production changes to the car are documented in the Technical Bulletins
publication available through most DeLorean specialty shops as well as the part number
changes in the Parts Catalog.
