The Isotta Fraschini Type KM is a passenger car produced by Isotta Fraschini from 1910 to 1914.

Launched in 1910 in Paris, the KM was one of the most powerful cars of that era. It possessed such a huge amount of power, thanks to the large 10.6 litre engine. At that time, the engine power could only be derlivered by means of a chain drive. The car was, however, very advanced in some aspects, it had brakes on all four wheels. This system, designed by Oreste Fraschini, involved the use of separate front and rear brakes.

There was a choice of engines supplied. There was the choice of an 100/120cv Italian engine or one of American origin which produced 140hp. With the first setup, the KM could reach a top speed of 130 k /h, with the second the KM could reach a top speed of 160 km/h .

The production was limited to only 50 cars.
