Παγκόσμια πρώτη με 16 βαλβίδες στο RAC '88 για το Όπελ Καντέτ GSi 16V ή Βόξολ Άστρα GTE (όπως θέλουν οι Βρετανοί). Το καλύτερο ίσως αυτοκίνητο αυτή τη στιγμή, με κίνηση στους δύο τροχούς θα συνεχίσει τη χρονιά που μόλις άρχισε, στα χέρια του Μάλκομ Ουΐλσον. Εδώ, ο "ευκαιριακός" Ντέρεκ Μπελ που οδήγησε περισσότερο για την τηλεόραση στο χιονισμένο τελευταίο αγώνα της χρονιάς που έφυγε (Auto Express -GR 258, 1/1989)
