As from March 1974, due to the 1973 oil crisis and the need for
economical cars, the 1-liter OHV engine was available for the
Kadett C, alongside the existing 1.2N and 1.2S.
Little is known about the production duration of this 1.0
engine. Folders and lists from that time give no information on the
models in which it was fitted. Also documentation, such as the
Oracle of P. Olyslager and the car handbook of Kluwer/Haynes about
the Opel Kadett C, offer no help or addition to other
documentation. In the book of Kluwer/Haynes there is a
mention of the 1.0S as an engine, but is lacking information,
such as the specifications.
From the data and specifications in the original workshop handbook
of General Motors engines, we can conclude however that it provided
1.0N in the Kadett and not 1.0S.
The need for a C Kadett with a 1-liter an engine was apparently
not large, because this engine was only available for a very short
time and not many were sold.
Original Kadett C with such an engine are therefore real a
scarcity!

The1.0N OHV engine is a descendent of the original from the type
A Kadett (constructed from 1962 - 1965). This engine was admittedly
re-introduced in the Kadett C in an almost unaltered form.
Specifications mentioned below come partly from the GM workshop
handbook, or data of the A Kadett.
In addition the data of 1.0S have been included but these were
almost certainly not available in the C Kadett.
