CREATE TABLE table_11138 ("model" CLOB, "max. motive power" CLOB, "max. torque at rpm" CLOB, "engine displacement" CLOB, "engine type" CLOB, "engine configuration & notes 0-100km/h" CLOB)

SELECT "engine type" FROM table_11138 WHERE "model" = 'base 2.4'
SELECT "engine type" FROM "table_11138" WHERE "model" = 'base 2.4'
