Question: Among the cars introduced in 1977, provide the names and the horse powers of cars from Europe.
Evidence: introduced in 1977 refers to model_year = 1977; car's name refers to car_name; from Europe refers to country = 'Europe'

SQL:
SELECT T1.car_name, T1.horsepower FROM data AS T1 INNER JOIN production AS T2 ON T1.ID = T2.ID INNER JOIN country AS T3 ON T3.origin = T2.country WHERE T2.model_year = 1977 AND T3.country = 'Europe'
