Both brothers, who had always been at the wheel of their own cars in the years of racing, entered the memorable "race-of-death," Paris-Madrid, in May, 1903. Louis arrived first at Bordeaux, but his unfortunate brother Marcel, while close to victory, was killed with the overturning of his machine only a few kilometers from the goal. In memory of Marcel Renault a simple monument was unveiled at Billancourt May 26, 1904, on ground contributed by the municipal council; a bronze plate on one side of this perpetuates his triumphant entry into Vienna, showing his arrival at the finish. Louis Renault, since continuing the business, has now produced larger machines, including the sixty to ninety horse-power made for the Vanderbilt race in America, October, 1904.
