New Delhi:Michael Schumacher has indicated his retirement at the end of the 2006 season slamming the brakes on a 15-year career. He has 90 race wins, seven championship titles and broke almost every record in the sport. The man who would go on to become Germany's first and only Formula One world champion started karting at the age of four in a machine built by his father Rolf and powered by a lawnmower engine. He started in Jordan in 1991 and Schumi announced that the chequered flag at the Brazil GP in December would mark the end of his illustrious career. String of records A measure of his greatness is provided by his tally of 1354 championship points, which is almost twice that of former greats Alain Prost and Ayrton Senna, who are the next highest point-winners. He also holds the record for garnering a stupendous 148 out of a possible 180 points in the 2004 season, having won 13 out of the 18 races that year. His record of 24 consecutive race finishes without retiring is also unmatched. He's the only driver to lead over 5000 laps, and the only man to win the same Grand Prix 8 times having made the French Grand Prix at Magny cours his own. Schumi, who has never been involved in a personal scandal like fellow countryman Boris Becker, will continue his efforts towards charity something that he never showed to his fellow race drivers during his career. The Ferrari driver will be remembered for the way he dominated Formula One for over a decade, and, more importantly, the way he drew fans to this sport with his attractive brand of driving.
