[2] In the mid-1970s Waldegård took part in the newborn European Championship for Rallycross Drivers with a privately entered Porsche Carrera RSR.

The Alitalia-backed Lancia team of the 1970s frequently choose between star drivers Waldegård and Italian frontrunner Sandro Munari.

Waldegård had a four-second lead over Munari entering the final stage, only to be forced to squander that advantage in keeping with the team's hopes for an 'equal' shootout.

He was later victor in the inaugural World Rally Championship series in 1979 for Ford and Mercedes-Benz, beating Hannu Mikkola in the final round at the Rallye Côte d'Ivoire in the Ivory Coast, by finishing second behind his rival.

The Targa Florio was more or less a rally-type race on a closed circuit made up of public roads, hence the reason for Waldegård's one-off drive with Porsche.
