BMW - Motorcycles and Automobiles

Motorcycles
BMW began production of motorcycle engines and then motorcycles after World War I. Its motorcycle brand is now known as BMW Motorrad. Their first successful motorcycle, after the failed Helios and Flink, was the "R32" in 1923. This had a "boxer" twin engine, in which a cylinder projects into the air-flow from each side of the machine. Apart from their single-cylinder models (basically to the same pattern), all their motorcycles used this distinctive layout until the early 1980s. Many BMWs are still produced in this layout, which is designated the R Series.

During the Second World War, BMW produced the BMW R75 motorcycle with a sidecar attached. Featuring a unique design copied from the Zündapp KS750, its sidecar wheel was also motor-driven. Combined with a lockable differential, this made the vehicle very capable off-road, an equivalent in many ways to the Jeep.
In 1982, came the K Series, shaft drive but water-cooled and with either three or four cylinders mounted in a straight line from front to back. Shortly after, BMW also started making the chain-driven F and G series with single and parallel twin Rotax engines.
In the early 1990s, BMW updated the airhead Boxer engine which became known as theoilhead. In 2002, the oilhead engine had two spark plugs per cylinder. In 2004 it added a built-in balance shaft, an increased capacity to 1,170 cc and enhanced performance to 100 hp (75 kW) for the R1200GS, compared to 85 hp (63 kW) of the previous R1150GS. More powerful variants of the oilhead engines are available in the R1100S and R1200S, producing 98 hp (73 kW) and 122 hp (91 kW), respectively.

In 2004, BMW introduced the new K1200S Sports Bike which marked a departure for BMW. It features an engine producing 167 hp (125 kW), derived from the company's work with the Williams F1 team, and is lighter than previous K models. Innovations include electronically adjustable front and rear suspension, and a Hossack-type front fork that BMW calls Duolever.
BMW introduced anti-lock brakes on production motorcycles starting in the late 1980s. The generation of anti-lock brakes available on the 2006 and later BMW motorcycles pave the way for the introduction of electronic stability control, or anti-skid technology later in the 2007 model year.
BMW has been an innovator in motorcycle suspension design, taking up telescopic front suspension long before most other manufacturers. Then they switched to an Earles fork, front suspension by swinging fork (1955 to 1969). Most modern BMWs are truly rear swingarm, single sided at the back (compare with the regular swinging fork usually, and wrongly, called swinging arm). Some BMWs started using yet another trademark front suspension design, the Telelever, in the early 1990s. Like the Earles fork, the Telelever significantly reduces dive under braking.
BMW Group, on 31 January 2013 announced that Pierer Industrie AG has bought Husqvarna for an undisclosed amount, which will not be revealed by either party in the future. The company is headed by Stephan pierer (CEO of KTM). Pierer Industrie AG is 51% owner of KTM and 100% owner of Husqvarna.

Automobiles
The New Class (German: Neue Klasse) was a line of compact sedans and coupes starting with the 1962 1500 and continuing through the last 2002s in 1977. Powered by BMW's celebrated four-cylinder M10 engine, the New Class models featured a fully independent suspension, MacPherson struts in front, and front disc brakes. Initially a family of four-door sedans and two-door coupes, the New Class line was broadened to two-door sports sedans with the addition of the 02 Series 1600 and 2002 in 1966.

Sharing little in common with the rest of the line beyond power train, the sporty siblings caught auto enthusiasts' attention and established BMW as an international brand. Precursors to the famed BMW 3 Series, the two-doors' success cemented the firm's future as an upper tier performance car maker. New Class four-doors with numbers ending in "0" were replaced by the larger BMW 5 Series in 1972. The upscale 2000C and 2000CS coupes were replaced by the six-cylinder BMW E9, introduced in 1969 with the 2800CS. The 1600 two-door was discontinued in 1975, and the 2002 replaced by the 320i in 1975.
The 1 Series, originally launched in 2004, is BMW's smallest car. Currently available are the second generation hatchback (F20) and first generation coupe/convertible (E82/E88). The 3 Series, a compact executive car manufactured since model year 1975, is currently in its sixth generation (F30); models include the sport sedan (F30), and fourth generation station wagon (F30), and convertible (E93), and the Gran Turismo. In 2014, the 4 Series was released to replace the 3 Series Coupe. The 5 Series is a mid-size executive car, available in sedan (F10) and station wagon (F11) forms. The 5 Series Gran Turismo (F07), debuted in 2010, created a segment between station wagons and crossover SUV.

BMW's full-size flagship executive sedan is the 7 Series. Typically, BMW introduces many of their innovations first in the 7 Series, such as the iDrive system. The 7 Series Hydrogen, featuring one of the world's first hydrogen fueled internal combustion engines, is fueled by liquid hydrogen and emits only clean water vapor. The latest generation (F01) debuted in 2009. Based on the 5 Series' platform, the 6 Series is BMW's grand touring luxury sport coupe/convertible (F12/F13). A 2-seater roadster and coupe which succeeded the Z3, the Z4 has been sold since 2002.
The X3 (F25), BMW's second crossover SUV (called SAV or "Sports Activity Vehicle" by BMW) debuted in 2010 and replaced the X3 (E83), which was based on the E46 3 Series' platform, and had been in production since 2003. Marketed in Europe as an off-roader, it benefits from BMW's xDrive all-wheel drive system. The all-wheel drive X5 (E70) was BMW's first crossover SUV (SAV), based on the 5 series, and is a mid-size luxury SUV (SAV) sold by BMW since 2000. A 4-seat crossover SUV released by BMW in December 2007, the X6is marketed as a "Sports Activity Coupe" (SAC) by BMW. The X1 extends the BMW Sports Activity Series model lineup.
