The Artist.....
Champion Elect
You probably have a little more historical knowledge than me. I personally cannot think of a single time that a driver has qualified in the top 6 (ahead of at least one of the fastest 3 cars) entirely on merit and then won the race (faster than all cars) entirely on thier own merit. Normally a gamble on wet set up, for rain to materialise and enable them to carve up the field, timely safety car (or premeditated safety car) etc.
Midfield cars only win races where circumstances skew relative performance. A good driver is necessary to win any race but if the machinery is not up to scratch and there are no acts of god it just won't happen.
Extremeninja - You're absolutely right - in general, the only way a midfield car wins is when there is something "different" about the race....
From my list - 6 of the races were wet races....
However, there are some occasions when drivers qualified cars in positions where they had no right to be - the Dallara and Minardi on the first two rows in Phoenix 1990 spring immediately to mind!
Further to this - the greatest "nearly" came in 1991 - Andrea de Cesaris in the Jordan - he was closing in rapidly on leader Senna at the Belgian grand prix, only for his car to fail in the last few laps! Had Schumacher not burnt his clutch out at the start that day, he would surely have won the race!.......
