BMW
After the end of World War I in 1918, BMW was forced to cease aircraft engine production by the terms of the Versailles Armistice Treaty. To remain in business, BMW produced farm equipment, household items and railway brakes. In 1922, former major shareholder Camillo Castiglioni purchased the rights to the name BMW, which led to the company descended from Rapp Motorenwerke being renamed Süddeutsche Bremse AG (known today as Knorr-Bremse). Castiglioni was also an investor in another aircraft company, called "Bayerische Flugzeugwerke", which he renamed BMW.The disused factory of Bayerische Flugzeugwerke was re-opened to produce engines for buses, trucks, farm equipment and pumps, under the brand name BMW. BMW's corporate history considers the founding date of Bayerische Flugzeugwerke (7 March 1916) to be the birth of the company.
BMW New Six
The BMW New Six (also known as the BMW E3) is a line of full-size luxury sedans and related coupés produced by the German automaker BMW from 1968 to 1977. All models used the then-new M30 straight-6 engine. It marked BMW's return to the full-size luxury sedan market after a hiatus of 5 years and was introduced as a response to growing market segment dominated by Mercedes-Benz. It was important in establishing BMW's reputation as a maker of sporting, luxury sedans.
