What is horsepower of F1 engine?

The Formula 1 racing cars are very high power engines. During the initial stages of F1 (during the late 1940s to early 1950s) the engines had a power ranging between 300 to over 500 Hp. The engines were reduced in capacity several times by the mid 60s.

Starting with 1966 power slowly started going up again, and during the 1980's some cars even had more than a 1000 Hp in qualifying trim. This was the time when turbo chargers were allowed. After 1988 the turbo chargers were banned and eventually the engine hp started coming down to around 600 Hp. After the year 2000 strong F1 race winning cars have produced over 900 Hp at the peak of the V10 era. As V10s were banned power output dropped as is now between 750-850 hp.
