The Isotta Fraschini Tipo KM is a luxury car produced between 1910 and 1914 in Italy. Only 50 were built.[1] Many of those 50 examples were exported to the United States, where the company had a branch on New York's Broadway.
The KM was introduced in Paris in 1910. It was one of the most powerful cars at that time. It has a 10.6 litre engine, with power transferred via chain. It has brakes on all four wheels, and a system developed by Oreste Fraschini allows for using front or rear brakes individually.
There were two engine options -Italian 100/120 hp or American 140 hp, top speed 130 km/h or 160 km/h with the American option being more powerful.

The engine was an advanced single overhead camshaft four, benefiting company's experience in the new technology of aeroengine design and manufacture, with bi-block cylinders, four big valves per cylinder and lightweight construction. The engine of the Tipo KM, developed 120 hp at 1600 rpm, had a bore and stroke of 130 x 200mm (5.12x7.87 in), liberally-drilled pistons of the finest BND Derihon steel that weighed less than 32 ounces (907 grams) and tubular BND conrods 16 in long that tipped the scales at just 7 lb (3,1 kg).[2]
