Giampaolo Dallara designed the WD1 of which three were built, two for Walter Wolf Racing and one for an Italian privateer. The monocoque proved to be too flexible and it was stiffened during the course of the season. Suspension was conventional and a Toyota Novamotor was fitted, apparently a Hewland FT200 gearbox was used which, if correct, is odd as this is the F2 spec ‘box, the Hewland Mk9 5-speed is the normal unit. Although it is true that in the mid-eighties using a FT200 in F3 was a recognized “tweak” adopted by some teams so perhaps Wolf were just ahead of the times.
The car was generally outclassed by the more established marques, Chevron, March, Ralt etc. but there were occasions when it showed potential especially as it was sorted. Rahal managed 3rds at the Nurburgring and Österreichring and 4th in a heat at Monaco.
