1988 saw Brazilian Ayrton Senna take victory in the all-conquering &lt;a href="McLaren%20MP4/4"&gt;McLaren MP4/4&lt;/a&gt; with its Honda turbo engine, and the following year he so very nearly won again, but the Honda engine in his McLaren failed and Belgian Thierry Boutsen took victory, which was the first in his F1 career. 1990, like the year before, was a rain-soaked event, and it saw a number of accidents; Senna came out to win again. 1991 saw a dramatic finale in which Nigel Mansell's Williams failed on the very last lap only a few corners from the finish line; Nelson Piquet took his 23rd and final F1 victory in a Benetton. Austrian Gerhard Berger won the 1992 event after the dominant Mansell spun off after a collision with Berger's teammate Senna. Alain Prost won the 1993 event while fending off a spirited drive from Senna, and in response to the Imola tragedies, the 1994 event saw the very fast Droit du Casino curve being turned into a chicane. German Michael Schumacher won this event. Ferrari's Jean Alesi won the 1995 edition, which occurred on his 31st birthday and which would be the only win of his career. Alesi had inherited the lead when Michael Schumacher pitted with electrical problems and Damon Hill's hydraulics failed. The victory was a popular one for Alesi, particularly after several unrewarded drives the year before, namely in Italy. Alesi's win at Montreal was voted the most popular race victory of the season by many, as it was the number 27 Ferrari—once belonging to the famous Gilles Villeneuve at his much loved home Grand Prix. Schumacher gave Alesi a lift back to the pits after Alesi's car ran out of fuel just before the Pits Hairpin.
