Opel Kadett GT/E
While
Vauxhall was using the Chevette on the British Championship, Dealer Opel
Team (DOT) in Europe was Rallying the Kadett GT/E. Introduced into Group 1,
2 and 4 Rallying in 1975 the Kadett had a 4-cylinder in-line front mounted
longitudinally at the front. Engines were 150bhp 8-vave, 207bhp 8-valve
engine, this was replaced in 1976 by a 240bhp 16v engine which proved to be
very trouble some and was named the ‘night mare engine’. Reliability of
this engine was that bad that it was rare that the car lasted a whole
rally. The car’s début was in 1975 at the hands of Walter Rohrl on the
Sanremo Rally. Walter did not finish the event as his transmission broke.
The car also failed to finish the RAC Rally that year as well.

However one
of the main weak points of the car was the torque tube rear suspension which
was also a weak point on the Ascona. With every increase of power of the
engine there was another step of unreliability further down the drive line.
Much was expected of the new 16v engine in 1976, however the engine was so
unreliable that the most of the works cars failed to finish and most points
scored by the Kadett went to private entry’s running 8v engines. 1977 was
not much better with a host of retirements for driver s Jean-Pierre Nicholas
and Walter Rohel. In April 1977 Tony Fall took over the Eurohandler Team
from Helle Bein and attempted to sort out the cars trouble’s.

The 16v
engine was abandoned and the old Group 2 engine from the Ascona was fitted
to the Kadett. And the car was sent to the Acroplois Rally but still failed
to finish. At the end of 1977 Walter Rohrl left the team at the end of 1977
disillusioned with the lack of reliability. In 1978 the FIA banned 16-valve
engine’s, so the Kadett was entered in Group 1 and Group 2 on various
events. The Opel Ascona 400 was just round the corner.
