It was interesting to do cause before I started I had no idea who would "Win" in 93
I thought it would be interesting to see what would happen in 1993 had the dominant Williams not been involved that year. This was the last full year for Senna of course. Both had similar engines – versions of Fords V8. Benetton had a slightly more powerful version till the British GP – then Mclaren & Benetton had the same versions at their disposal. Mclaren probably had better driver aids especially for the start of the season. So here we go.
Williams excluded from the 1993 F1 Championship. In an adminstrative oversight Williams put in their official entry one day late and thus miss the 93 championship.

Bernie is not too worried says it should improve TV ratings after the Mansell whitewash last year.
Prost says it is a conspiracy against him.

Some stats
Qualifying was very close 8-8
Average qualifying position MS 1.9375
Average qualifying position AS 2.0625
Race Wins equal with 7 each
Points close only seven in it.
Both had 4 DNF due to the car
MS had 3 accidents vs Senna 1 (Although MS has one accident with senna which put him out of the race)
MS lowest finish was 2nd ! Results 7 Wins and two 2nds !!
Senna owest finish was 3rd Results 7 Wins and two 2nds , 3rd and a fourth!
I am not counting the 4th as he ran out of fuel on the last lap!
To my mind this proves one thing – Schumacher & Senna were very equal in speed and race performances.
