CREATE TABLE table_name_63 (laps INTEGER, time_retired VARCHAR(255), grid VARCHAR(255), constructor VARCHAR(255))
When renault is the constructor, the grid is over 6, and the time was labeled ignition, what's the largest amount of laps on record?
    
SQL: SELECT MAX(laps) FROM table_name_63 WHERE grid > 6 AND constructor = "renault" AND time_retired = "ignition"
