Kadett 4S
 
"Opel was working on a group B/group S car, the Kadett 4S based on the Kadett E/Astra MkII shell. Again Opel went shopping at independent tuners and tried to put the pieces together. This ended in quite some PR embarrassment as Opel proudly announced they had this superb 500hp engine, only for the press to realize – and of course taking profit of this farce – that what Opel praised in highest respects was a Ford engine they purchased through Zakspeed! However, when Group S was due to be dropped by FIA they build another one and fitted both with 2.4L Manta 400 engines for the Paris-Dakar - to face a disaster there due to lots of broken shocks."
