At last week's Tour Auto, arch-rivals Porsche and Ferrari were very strongly represented. Among the rarest of Porsches competing was the 911 Carrera RSR 3.0 of which two were raced. Built by Porsche in 1974 and 1975, it was the ultimate evolution of that naturally aspirated Porsche 911 racers before the German manufacturer switched to the turbo-charged 934s and 935s. Although homologated as a GT racer, the three-litre engined Carrera RSR also scored two outright victories each in the Sebring 12 Hours and Daytona 24 Hours. Added to the six examples already featured, the pair of RSRs were extensively raced in period by prominent French and German privateers. They are pictured in what is now a 178-shot gallery.
Of a somewhat earlier vintage is this Ferrari 212 Export Touring Berlinetta, which ran strongly for three of the event's five days. One of just four built, this rare fixed-head machine combined the classic Touring lines with latest 2.6-litre engine introduced by Ferrari in 1951. The example that participated in the Tour Auto burst back onto the scene early in 2014 when it sold for over $3 million at a Bonhams auction. As can be seen in this 37-shot gallery, it has since not only competed in the Tour Auto but was also shown at Pebble Beach back in August.
