The two featured drivers in the video Johnny Servoz-Gavin & Jean Pierre Beltoise in the Matra MS5's both retired with Engine Failure.
Servoz-Gavin on the 8th lap & Beltoise on the 16th lap. Jochen Rindt won the race.
Here are the full results :)  :

the conversation between Beltoise and Servoz is full of infos

He says that to get a very good lap times,he needs to be the last on a pack of four, and then use the slisptreaming to be the first on the end of the lap.This way, you gain 2.5 snd per lap, a thing impossible to achieve alone on the track .

Beltoise says he has been lucky to do it, when he met Brabham, Stewart and Ickx and stayed behind them

  The mechanic says overevving doesn't do anything bad for the valves (contrary to a popular belief ), but for the connecting rods screwing

About the tires, Servoz says the Michelin had clearly an edge on the Good Year, the gap being 2" / lap.

Very interesting stuff :) . Seems to back up the data from the 1966 F1 race we used to calculate the slipstream effect :) .

The report begins with a Servoz that get hurried with the woman timekeeper . Talks have relatively no interest

Then, when Beltoise stops,  we learn that the FVA water temp after Servoz stop reach 90°

Beltoise to the manager: "you shld change the steering wheel, or change the spoke axis, as I can 't see the water temperature "

then  the journalist ask Servoz :

"why Beltoise is testing your car ?
because he want to do a tire test" ( he was testing Michelins)
Then Beltoise stop and says about them : " it is not bad" " It is not bad " ... then " but I think they are a little bit too wide at the back "

Claude Leguezec, that was the team manager ask Beltoise :

" Do you want to test the Good Year ?
Yes "


Then they fit the Good Year

Then the drivers talk, seated on the grass :

Beltoise to Servoz :

-" What lap time do you get with the Michelin ?

- 2'17" and something ..
someone told him : 2'17"5

-Alone ?

- yes ... but with the Good Year, 2'19"5 or 7, I think ...

Why did you stop when I was towing  you ?


Servoz answer isn't clear, and Beltoise remind him that they did 3 laps together, and if he wldn't have stop,Servoz time wld have been better

then Beltoise explain the  advantage of 4 men together in a pack ( see post above)

Servoz says he want to go back to the Michelins

Beltoise then :

"Yesterday, once the engine was set correctly, we tried the gear ratios.But on the snd day of practice,we did some tyres testing, but on that day, the only thing you have to do is manage slipstreaming.
If you are better than a competitor on a corner, you will get a gain of 3 meters at best, and if he regain it, he is better than you . But with slipstreaming, you can gain 50 meters in a single lap on him ! So the problem of all this is the slipstreaming. "


The journalist : "so it is not a matter of virtuosity, but luck ..."

Beltoise : " not so much ...
journalist : " Reims is a lottery
Beltoise : " .... you need courage.. because the cars are moving a lot on the straights ... and when you brake, you need to have room for 50 centimeters on each side .Under braking,the car front train moves roughly 50 cm left and right ... Three cars together are under braking in front, and the track width is only 7/ 8 meters.....or 9 at max......and this is very dangerous, because our wheels are separated by only few centimeters, and you are at more than 250 km / h".

then the journalist ask what are the main risky points of the track

Beltoise : " the very fast Dunlop curve that is flat out ...and for sure the two corners in the background ".... " and that's here that experience helps a lot,the more you run fast curves, the more you get the feeling that they are more and more slow... And finally, when you think that they are slow, going through at 200 km/h, that's means then you are ready "  

on the next briefing, we learn Beltoise decide finally to race on Dunlops ! ( I remember Beltoise saying at the Formula 2 season end that the fact Matra work team didn't get a contract with a tire manufacturer, had been finally at a disadvantage )

Beltoise : I will race with a longer first gear  Servoz : " me ,too "
They had a 13/35 and they ask a 14/34

Servoz : " I will race with the Michelin, and I want a tire pressure at Two kilos, front and rear "

finally, raceday, they DNF ... and after a talk, they wonder if the cause is a rich fuel / air mixture, or a poor fuel/air mix ...

Michel,
Thank you for the detailed narrative here. :up:

Reims is a unique track in GPL with the slipstreaming effect. :woohoo2:

you see those cars swerved a lot under heavy and short braking.
Who says GPL original physics are like driving on ice ? The steering wheel correction we do with some setups maybe aren't that far from what period drivers had to do ...

braking for the Parabolica corner at Monza with some 67 F1 replicate in some ways this sensation, isn' it ?
