I've checked archives of Motorsport magazine.
Worth noting that before 1993 term "safety car" was not used when mentioning safety car in modern meaning.
Introduction of safety car:
It's interesting that that procedure was not applicable to Nurburgring !
Letter about pace car:
1978 spa 24h pace car was used
"Unlike after the Craft accident the contestants were not asked to line up behind the pace car, the race carrying on unabated as the haze of smoke drifted away. "
USAC Brands hatch - Special Capri used as pace car
"Above, Mike Wilds in the special Capri pace car leads Al Unser, Ongais, Johncock and Sneva towards the rolling start"
Pace car regulations were to be used in 1978 USAC races in UK
"Full USAC regulations will apply, including pace car rolling starts, refuelling and the yellow-flag slowdown procedure."
1983 Brands Hatch 1000 used safety car
"By this time the track was flooding at Graham Hill bend (nee Bottom Bend) and the clerk of the course sent out the pace car for five laps to slow the competitors down. This reduced Warwick's advantage, but resulted in lckx being lapped as the pace car joined the circuit in front of him"
1984 RAC Turist trophy used pace car
"On the track there were spins galore and the wonder is that more cars were not writ ten off. Out came the pace car ahead of Thackwell, who had taken over from Weaver, in the storm, but Stack's timely pit stop meant that ()nester was out in front with a 90 second lead. Although the rain quickly stopped, the track was awash and the field splashed around for half a dozen laps. When the pace car peeled off, Quester led from Brancatelli with Walkinshaw a long was back"
1984 Fuji 1000kms used pace car
"The Alba was written off, Bellof continued at full speed until the pace car came out, and Mass was seen overtaking a slower car while the yellow flags were out"
It seems that since 1985 pace car was used in WSC
Le mans 1985 pace car
" The Canon team had 30-litres remaining, as did Bell and Stuck who completed 366 laps. Had the pace car not gone out for 25 minutes on Saturday evening, when Jean-Claude Andruet crashed a WM-Peugeot mightily on the Mulsanne straight (another tyre deflation was the cause) even more records might have been broken."
1986 Tourist trophy Silverstone pace car
"Then Quester and Rossi collided at Club (the early stages were a panel beater's dream) and the incident left Rossi stranded on the racing line so the pace car was called out while the car was removed.
Several laps behind the pace car closed the field up and allowed the turbo cars just a little extra fuel to play with before the mid-race pit stop."
1988 Bathurst 1000kms used pace car
"However, it all started to fall apart as the 100-lap mark was clocked up, the pace-car being called into operation for the second time in the race to clear a damaged car off the track"
1992 Mosley wants F1 to have pace cars
"May 2: Max Mosley announces that FISA is considering the introduction of a pace car to F1 events."
1992 Pace car possibly used in F2
"Oct 11: A misunderstanding over pace car regulations costs Yvan Muller victory in the British F2 finale at Donington Park. Series debutant Massimo Monti wins."
Competition pace cars in 1993
" Throw in the frankly ludicrous suggestion of a non-safety pace car to prevent any race leader building more than a 12s cushion and you can quite easily be forgiven for believing that the highest echelon of the sport has gone completely loopy."
"Nevertheless, Ecclestone is smart enough to appreciate that IndyCar racing, set to be televised via satellite in the UK this year, is going to pose a major threat now that Mansell has switched sides. The desperation is evident in the laughable idea of the non-safety pace car."
"Motor racing's governing body has come up with some pitiful ideas in recent weeks, most notably the suggestion that a pace car should be used to tighten up F1 fields whenever a Grand Prix leader opened up an advantage of 12 seconds."
"21: Benetton's Flavio Briatore is in combative mood. The Italian is pushing for changes to F1's existing Concorde Agreement, and also seeks unanimous approval for the introduction of a 'non-safety' pace car, an artificial — and somewhat ridiculous — means of closing up a Grand Prix should the leader eke out an advantage of 12 seconds."
"Shortly after a time when FISA was seriously suggesting a system wherein a non-safety pace car would be deployed if and whenever a leader amassed a cushion greater than 12s - supposedly to 'spice up' F1- it is not difficult to envisage a final odd quirk before the nonsense subsides and the real racing mercifully begins again."
1994 Japan GP - metion of 'Official car', other that safety car. Any idea what was it?
"As the wrecked cars were cleaned away the race continued, with the safety car and then an official car deployed to slow things down. The former did not immediately pick up on the leaders because they had gone by before the incidents began, but Schumacher in particular showed commendable common-sense by obeying the yellow flags and his radio messages and resisting any temptation to push too hard in his chase after the safety car. Since Suzuka has such a long lap, the official car also went out to hold the field, and as the rain gradually began to ease team managers went up to the stewards to voice their opinions as to whether the event should be stopped. Eddie Jordan was among the most vocal, as is his desire, expressing his driver's views that the race should be stopped immediately."
1993 British Gp - Ford Escort RS Safety was used
