Corsa Sprint Studie
Corsa Sprint
Opel-Motorsport-Prototype
On
the Frankfurt Motor Show in September 1983 Opel showed the prototype "Corsa Sprint", which was developed in co-operation with Irmscher.
This prototype should demonstrate, what was feasible with the Corsa. A Motorsport Corsa was developed in the context of the
Group B regulations.

It was planned to do a low volume
production of 200 cars if there would be a large interest.
Furthermore a regular production of the
body panels was planned.



In the interior the
Rally atmosphere dominated: Aluminium roll cage, lightweight
construction instrument panel made of aluminium, heat isolation of
aluminium foil.
The instruments,
which were developed by the Opel Design centre, were installed with
quick-locking mechanisms on the instrument panel, so that they could
be changed very easy. The speedometer had an analog and a digital
display.
Behind the
lightweight seats a 80-litre gasoline tank was installed, on which 2
helmets could be put down in formed trays.


The 1,3 litre engine
was highly modified, so that nearly an engine output per litre of
100HP was reached
The chassis was
dropped by 30mm, Bilstein gas absorber and harder springs were
fitted
