That's great research morgul, thanks. Those results for the 122S in the 1960s highlight that its only weakness at Mount Panorama was power-to-weight ratio, because otherwise it had the handling, braking and reliability to run 500 miles flat-out. The fourth place in Class D for open-wheeler aces Bartlett and Harvey in 1966 (behind the two VC Valiant V8s and a Triumph 2000) was a good example. They knew the Volvo did not have the raw speed required to win the class, so they decided they’d just drive it flat-out in the hope it would break so they’d get an early mark and go home. However, the 122S was so tough they could not break it. KB said they were redlining it in every gear and driving it as hard as it could possibly go, but it just kept circulating without complaint. At the end of the day, they both couldn’t help but be impressed by it! They also found out later from Gerry Lister (who supplied the car) that during a post-race strip-down he discovered one of the lobes on the camshaft had gone a bit soft for some reason. So, it wasn’t fully opening one of its inlet valves, which cost them a bit of speed. Given that handicap, I reckon fourth in class was a solid effort and proved how robust the 120 series Volvos were. Imagine if they'd also had V8 power - would have been quite a battle with those Valiants!
