The craziest car you've never heard of
In December of 1905 driver Victor Hemery broke the outright land speed record with this 25Liter V8 Darracq 200. On a dirt road outside of Paris, he did the flying kilometer at a speed of 109.025 mph which held for only two months.
The Darracq was designed by Louis Ribeyrolles and was notable for having one of the world’s first V8 engines. Ribeyrolles essentially mated two inline-4 engines to a common crankshaft. This effectively doubled the output of the existing Gordon Bennett Darracq 100 engines and saved weight by using a common crankshaft and crankcase.
