And then there were three - Toulon joined Harlequins and ASM Clermont Auvergne as the only clubs to make it four from four before the tournament resumes in 2013 with a 62-0 victory over Sale Sharks at their Stade Félix Mayol fortress.
The nine-try romp took Toulon to 18 points, five clear of French rivals Montpellier, with quarter-final qualification firmly in their own hands with ties against Cardiff Blues and Montpellier to come next month.
Frederic Michalak - who ended up with a 20 points contribution - struck the first blow with a fifth minute penalty goal but Sale's resistance held out for the opening half an hour before hooker Jean-Charles Orioli crossed for the first try.
Michalak, a player in prime form and given an outing at No 10 to give Jonny Wilkinson a break until the England World Cup winner came off the bench in the 67th minute, converted and then did the damage with the ball in hand, crossing for Toulon's second try after 36 minutes.
It came from a scrum and although he produced some neat footwork he also cashed in on some dubious defence to scramble over.
He landed the conversion for good measure to give the French club a comfortable 17 points advantage to take into the break.
That became 24 when captain and back row forward Joe van Niekerk crossed for their third try and the bonus point followed with half an hour to spare with prop Davit Kubriashvili getting on the scoresheet.
And there was still more pain for Sale to suffer, brothers Steffon and Delon Armitage each scoring tries in the space of six minutes with van Niekerk getting his second as Sale saw the home side top a half century of points.
Wing Rudi Wulf got their eighth and David Smith their ninth with Wilkinson getting in on the act with a conversion.
