user: Question: When the laps driven were under 9 and the time/retired recorded was engine, what's the total number of grid values?
Columns: ['Driver', 'Constructor', 'Laps', 'Time/Retired', 'Grid']
Types: ['text', 'text', 'real', 'text', 'real']
Sample row: ['Jim Clark', 'Lotus - Climax', 32.0, '2:23:34.8', 2.0]
SQL:

assistant: SELECT COUNT("Grid") FROM "Table" WHERE "Laps" < 9.0 AND "Time/Retired" = 'engine';
