Table schema:
CREATE TABLE table_name_25 (engine_capacity INTEGER, mpg_us_urban VARCHAR, co_2_g_km VARCHAR, manufacturer VARCHAR, mpg_uk_extra_urban VARCHAR)

Question: What is the highest engine capacity with a bmw manufacturer, an mpg-UK extra-urban of 52.3, a 176 CO 2 g/km, and an mpg-us urban greater than 27.3?
SQL: SELECT MAX(engine_capacity) FROM table_name_25 WHERE manufacturer = "bmw" AND mpg_uk_extra_urban = 52.3 AND co_2_g_km = 176 AND mpg_us_urban > 27.3
