BMW

Bayerische Motoren Werke AG (German pronunciation: [baˈjɛɐ̯ɪʃə mɔˈtɔʁn̩ ˈvɛɐ̯kə]; German for Bavarian Motor Works), usually known under its abbreviation BMW, is a German luxury automobile, motorcycle, and engine manufacturing company founded in 1916. Headquartered in Munich, Bavaria, Germany, it also owns and produces Mini cars and serves as the parent company of Rolls-Royce Motor Cars. BMW produces motorcycles under BMW Motorrad, and plug-in electric cars under the BMW i sub-brand. It is one of the best-selling luxury automakers in the world. The company is a component of the Euro Stoxx 50 stock market index.

History

BMW was established as a business entity following a restructuring of the Rapp Motorenwerke aircraft manufacturing firm in 1917. 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. The company consequently shifted to motorcycle production as the restrictions of the treaty started to be lifted in 1923, followed by automobiles in 1928–29.

BMW N45

The BMW N45 is a straight-4 DOHC piston engine which replaced the BMW N42 and was produced from 2004-2011.

Compared with its N42 predecessor, the N45 does not have valvetronic variable valve lift. As the N42, the N45 has variable valve timing (called VANOS by BMW). The N45 was sold alongside the N43 (which has direct injection) and the N46 (which has valvetronic) straight-4 engines.
