Table schema:
CREATE TABLE table_name_12 (engine VARCHAR, transmission VARCHAR, acceleration_0_100km_h__0_62mph_ VARCHAR)

Question: What is the engine when the transmission was 4-speed automatic, and acceleration 0–100km/h (0–62mph) was 10.4 s?
SQL: SELECT engine FROM table_name_12 WHERE transmission = "4-speed automatic" AND acceleration_0_100km_h__0_62mph_ = "10.4 s"
