Bentley Motors, Limited is a British automobile manufacturer. It was established on January 18, 1919 by Walter Owen Bentley (better known as W.O. or simply as "O"). He became well known during World War I for his rotary aero engines used in the Sopwith Camel in later versions and it was called the Bentley BR I.
The Volkswagen Group of Germany has owned the company since 1998. They are based in Crewe, England and their central production facility is there.
Before the beginning of World War I, "O" Bentley ad been partnered with H.M. Bentley, his brother to sell French DFP automobiles. He had a burning desire to create and build his own line of cars under his own name.
So, in August, 1919, Bentley Motors was actually registered and they exhibited their first attempt at the London Motor Show that was held in October, 1919. It was only a chassis without a real engine. By December, 1919, they had an engine up and running.
Following the London Motor Show, they began taking orders for their cars, promising delivery by June, 1920. Actual development took longer than anticipated and actual delivery did not take place until September, 1921.
