Schema: CREATE TABLE table_name_63 (laps INTEGER, time_retired VARCHAR, grid VARCHAR, constructor VARCHAR)
Question: 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"
