In 1993, McLaren kicked off a good-natured spar with the Sega-sponsored Williams team as we both wrestled for world championship honours. This squashed hedgehog decal (a reference to Sega’s Sonic the Hedgehog) became a fighter-plane-style badge of honour that was applied to the MP4-8 McLaren-Ford whenever it took a grand prix win.
This sticker started to be placed after Senna's victory in the Brazilian GP in Interlagos (2nd round).
The 1993 European Grand Prix (formally the Sega European Grand Prix) was a Formula One motor race held on 11 April 1993 at Donington Park (3rd round). It was the third race of the 1993 FIA Formula One World Championship. The race was contested over 76 laps and was won by Ayrton Senna for the McLaren team, ahead of second-placed Damon Hill and third-placed Alain Prost, both driving for the Williams team.
Senna's drive to victory is regarded as one of his finest, and his first lap exploits are particularly lauded, in which he passed four drivers – Michael Schumacher, Karl Wendlinger, Damon Hill and Alain Prost – to take the lead in a single lap in torrential rain conditions. The race was the first held under the European Grand Prix title since 1985, and to date is the only Formula One Grand Prix to have been held at the Donington Park circuit.
