Largest car engine

The greatest engine capacity of a production car was 13.5 litres (823.8 cu in), for the US Pierce-Arrow 6-66 Raceabout of 1912-18, the US Peerless 6-60 of 1912-14 and the Fageol of 1918. Despite their massive size, these giants from the early days of automobiles were very inefficient compared to their modern counterparts. A typical modern family car has a relatively small engine capacity of between 1,3 and 2 liters (79.3 cu in and 122 cu in), with power output of between 45 and 90kW (60 and 120bhp). The Pierce-Arrow 6-66, despite having an engine more than 10 times the size of a modern 1,3 liter (79.3 cu in) hatchback, had roughly the same power output of 49kW (66bhp). Modern F1 racing cars,  comparison, have an engine capacity of around 3 liters and power output in excess of 559kW (750hp). Despite its relatively poor performance in modern terms, the six-cylinder Pierce-Arrow was a highly regarded vehicle in its day and is said to have been a favorite of smugglers during the prohibition era because of the smoothness and quietness of its engine.
