I know there have been quite a few perfect races (started on pole, led every lap, got fastest lap and then won) but has anyone ever gone one further and got fastest practice times in all three sessions as well as Q1 and Q2 ON TOP OF having a perfect race on the Sunday?
Here is the list of all drivers who have obtained a Grand Slam. We have to see in these Grands Prix if the driver has been on top in every session (I don’t know how regulamentated the sessions were some time ago).
I’m not sure where to find information about old free practice sessions. The amount of sessions has changed throughout the years. I found however that Mika Häkkinen had perfect weekend in Brazil 1998. Fastest in Friday practice (there was two one-hour sessions but times were counted together), fastest in Saturday practice (two 45-minute sessions, times together), qualifying and Sunday warm-up.
@calum, the Grand Slam also means that they led every lap. It’s harder to achieve a grand slam because of pit strategy. Even when Vettel has been dominant on a weekend, there have been drivers leading the race, but out of position due to not pitting yet.
