Finally, they won 15 out of 16 races, losing only at Monza when Senna, a country mile ahead of his closest rival, tripped over Jean-Louis Schlesser's Williams just two laps from the checkered flag. The defeat handed Ferrari a memorable 1-2 result on home ground just a week after Enzo Ferrari passed away.
In the end, with eight victories, Senna took the world title by 3 points from Prost. Complicit and instrumental in their triumph, McLaren's MP4/4 still looks stunning today whenever it is rolled out in all its glory. Superbly designed and packaged, beautifully raced, it is the epitome of collaborative and optimised engineering between two partners driven by only one goal: absolute triumph.
