Which is the largest engine

Biggest engine in the world

There is a lot of arguing about records, as several people can be right at the same time in a discussion. With the engine record, I now differentiate whether it is a series vehicle, racing vehicle or an individual construction.
Hence there are several record holders on this site.

Series vehicles
Dodge Viper SRT 10 from 2012 - 2017
The largest engine in the world is driven in a Dodge Viper SRT 10. With a displacement of 8.4 l, this car has the largest engine of modern times and thus holds the record. This engine has an output of 477 kW (649 hp), is no longer built and is therefore only available as a used car.

Individual vehicles
"Brutus" American LaFrance fire tip car
The "Brutus" is a racing car in the style of the early 20th century, but it was constructed between 1998 and 2006 by the Sinsheim Auto and Technology Museum. It has a BMW aero engine with 47 l (46,930 ccm) displacement with 12 cylinders in a 60 ° arrangement. It is atypical for today that the rows of cylinders have different displacements. The cylinders on the left have a capacity of 3.82 liters and on the left they have a capacity of 4.0 liters.
This huge engine can temporarily produce a maximum of 552 kW (750 PS) at 1,650 rpm, but is more capable of 405 kW (550 PS) in continuous operation.

race car
Unfortunately, there is little official information on this. At the beginning of the 20th century there were many attempts to break the 200 km / h limit. For this purpose, racing cars with a displacement of approx. 18 to 25 liters were built.
