The most popular and most sport orientated model of the Opel
Kadett C is the Coupé. Of all the Kadett C models the Coupé had the
most versions available. Also the top model of the Kadett C, the
GT/E, was only available as a Coupé. In standard form the
Coupé was some centimeters lower than the rest of the models.
The streamlined design of the Coupe gave a lower CW (drag
factor) value than the rest of the models in the range, as a result
of which faster acceleration and a higher top speed were possible.
As well as the standard model a Berlinetta, SR, GT/E and Rallye
were versions available.
The Berlinetta version was an extra luxury version of the Coupé.
The SR version had a mat black bonnet and rally striping. The
SR version was provided with harder absorbers, different tires and
a comprehensive dashboard with rev-counter, volt meter and oil
pressure gauge.
GT/E
The GT/E was introduced in 1975. Standard the car was Available
in the yellow/black war colors or a signal color. The car was
provide with 105hp 1.9 liters injection engine from the Manta. This
gave the GT/E acceleration of 0-100 in 10.2 seconds and a top speed
of 180 km/h.
THE GT/E had among other things. H4 head lamps, thicker
anti-roll bars and up rated suspension . Optionally the car was
available with 5 speed ZF gearbox and limited slip differential
with a lower final drive. The car was very popular in motor sport
and had a lot of success. A total of 8660 GT/E's were produced
between 1975 and 1977.
GT/E 2 and 1000-serie
From 1977 a new version of the GT/E was built which was called
the GT/E 2. This version of the GT/E was no longer available in the
colors yellow/black, but was provided in the colors
yellow/white.
The car was provided with 115hp 2 liters injection motor. The
acceleration of 0-100 km/h could be gained in 9.8 and the top speed
of the GT/E was 189 km/h. Standard was the car provide with
5-versnellingsbak (ZF), rearend differential and a rally
instrument. One wished Recaro tank L en and e.g. clock or a radio,
then one had those in the option list select. They were against
extra cost deliverable.
At first it was the intention to build1000 of these GT/E's for
homologation in motor sport. In the Netherlands you were
only to buy this car if you possessed a racing
license . This firs limited production run of 1000 gave
itself to the nick name of 1000 series or GT/E 1000.
The first production run of 1000 Kadetts GT/E's sold very
quickly, Opel decided in July/august 1978 to do another 500 in
yellow/blank, These also sold quickly and they made a final run of
754.
The total number of GT/E' built between 1977 and 1979 was 2254.
During the last production run GT/E's could be ordered several
clear (signal) colours .
It is known that these cars did not all have the same
specification. Some GT/E 2's were manufactured with sport
orientated 4 speed close-ratio gearbox instead of the earlier
standard ZF 5 speed and a 45% limited slid differential in place of
the stronger 75% version.
The last GT/E's were sold at the end of 1978 or beginning
1979.
Rallye
A street version of the GT/E introduced with the GT/E2 was
the Rallye . The Rallye was provided with a 75hp1.6S engine which
was from 1977 also available in the normal Kadetts, or a 110hp 2
liters injection engine.
The interior of the Rallye was almost the same as the GT/E
except that the rally instrument was deleted. The Rallye 1.6S had
acceleration 0-100 km/h in exactly 13 seconds, whereas the Rallye
2.0E brought this about in 9.5 seconds. Between 1978 and 1979 a
total of 8549 Rallye Kadetts were built.
