It replaced
196-416: A twin-scroll turbocharger and Valvetronic (variable valve lift). There have been several cases of recalls and/or extended warranty due to failing HPFP (high pressure fuel pumps) in the Prince engine. There was a service bulletin issued in 2013 due to failing timing chains and timing chain tensioner, both designed by BMW, in the Prince engine. The production of MINI version of 'Prince' family of engines
294-450: A BMW 7 Series (G11) special edition simply called "The Final V12", the last BMW series production vehicle to be fitted with a V-12 engine. On 5 October 2023 it was announced that BMW UK CEO Chris Brownridge would succeed Torsten Müller-Ötvös as the CEO of Rolls-Royce starting 1 December 2023, as a result of Müller-Ötvös retiring. BMW is an abbreviation for Bayerische Motoren Werke . This name
392-534: A built-in balance shaft, an increased capacity to 1,170 cc (71 cu in) and enhanced performance to 75 kW (101 hp) for the R1200GS , compared to 63 kW (84 hp) of the previous R1150GS . More powerful variants of the oilhead engines are available in the R1100S and R1200S, producing 73 and 91 kW (98 and 122 hp), respectively. In 2004, BMW introduced the new K1200S Sports Bike which marked
490-492: A departure for BMW. It had an engine producing 125 kW (168 hp), 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
588-442: A direct-injected engine refers to how the fuel is distributed throughout the combustion chamber: In the homogeneous charge mode , the engine operates on a homogeneous air/fuel mixture ( λ = 1 {\displaystyle \lambda =1} ), meaning, that there is an (almost) perfect mixture of fuel and air in the cylinder. The fuel is injected at the very beginning of the intake stroke in order to give injected fuel
686-645: A new Euro 6 engine based on the THP in the following Engine codes: The turbocharged 1.6 litre version used by BMW is called the BMW N13 . The N13 replaced the naturally aspirated BMW N43 engine and was produced from 2011 to 2016. It is BMW's first turbocharged four-cylinder petrol engine since the BMW 2002 Turbo ceased production in 1974. BMW sold the N13 alongside the larger displacement BMW N20 turbocharged four-cylinder engine. The N13
784-575: A number of awards in the visual arts. These include the BMW Art Journey award, which honors a young or mid-career artist in collaboration with Art Basel , and the BMW Painting Award, which was created to promote painting in Spain by finding new talent and showcasing their work. Gasoline direct injection Gasoline direct injection ( GDI ), also known as petrol direct injection ( PDI ),
882-418: A richer air-fuel ratio at higher loads. In theory, a stratified charge mode can further improve fuel efficiency and reduce exhaust emissions, however, in practice, the stratified charge concept has not proved to have significant efficiency advantages over a conventional homogeneous charge concept, but due to its inherent lean burn, more nitrogen oxides are formed, which sometimes require a NOx adsorber in
980-421: A spark-plug (due to a lack of fuel), the charge needs to be stratified (e. g. a small zone of fuel/air mixture around the spark plug needs to be created). To achieve such a charge, a stratified charge engine injects the fuel during the latter stages of the compression stroke. A "swirl cavity" in the top of the piston is often used to direct the fuel into the zone surrounding the spark plug . This technique enables
1078-512: A special swirl or tumble movement in order to direct the fuel towards the spark plug. This swirl or tumble movement must be retained for a relatively long period of time, so that all of the fuel is getting pushed towards the spark plug. This however reduces the engine's charging efficiency and thus power output. In practice, a combination of air-guided and wall-guided injection is used. There exists only one engine that only relies on air-guided injection. In engines with spray-guided direct injection,

#17328756709431176-551: A study published in January 2020 in the journal Environmental Science and Technology , a team of researchers at the University of Georgia (USA) predicted that the increase in black carbon emissions from GDI-powered vehicles will increase climate warming in urban areas of the U.S. by an amount that significantly exceeds the cooling associated with a reduction in CO 2 . The researchers also believe
1274-565: A total of 1,598 cc (1.6 L) of displacement. At first, there were two versions on offer – the THP150 and THP175, also known as the EP6DT and EP6DTS respectively within Peugeot. The first was later updated as EP6CDT and also as THP163, EP6CDTM . There is also EP6CDT MD – with lowered compression ratio. For the THP150 maximum torque is 240 N⋅m (177 lb⋅ft) at 1400 rpm. Power output
1372-540: A total of 1,598 cc (1.6 L) of displacement. The naturally aspirated variant ( EP6 , EP6C ) has conventional fuel injection and lost-foam cast cylinder heads . Its 11:1 compression ratio creates an output of 88 kW (120 PS) at 6000 rpm with a redline of 6500 rpm. Torque is 160 N⋅m (118 lb⋅ft) at 4250 rpm. Applications: The turbocharged 1.6 L unit adds gasoline direct injection and has special low-pressure die-cast heads. It has an 85.8 mm (3.38 in) stroke for
1470-438: A very high air ratio at its edges. The fuel can only be ignited in between these two "zones". Ignition takes place almost immediately after injection to increase engine efficiency. The spark plug must be placed in such a way, that it is exactly in the zone where the mixture is ignitable. This means that the production tolerances need to be very low, because only very little misalignment can result in drastic combustion decline. Also,
1568-545: Is 110 kW (150 PS) at 5500 rpm. Applications: For the THP163 maximum torque is 240 N⋅m (177 lb⋅ft) at 1400 rpm. Power output is 121 kW (165 PS) at 5500 rpm. Applications: For the THP175 ( EP6DTS , later EP6CDTS ) maximum torque is 247 N⋅m (182 lb⋅ft) at 1600 rpm, remaining flat to 5000 rpm. Power output is 129 kW (175 PS) at 5500 rpm. An overboost function

BMW Welt , the company's exhibition space in Munich, was designed by Coop Himmelb(l)au and opened in 2007. It includes a showroom and lifting platforms where a customer's new car is theatrically unveiled to the customer. In 1975, sculptor Alexander Calder
1764-539: Is a long-term shareholder of the company, following investments by the brothers Herbert and Harald Quandt in 1959 that saved BMW from bankruptcy , with the remaining shares owned by the public . The Otto Flugmaschinenfabrik was founded in 1910 by Gustav Otto in the Kingdom of Bavaria , which was a state of the German Empire . The firm was reorganized on 7 March 1916 into Bayerische Flugzeugwerke AG . This company
1862-427: Is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber . This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold). The use of GDI can help increase engine efficiency and specific power output as well as reduce exhaust emissions. The first GDI engine to reach production
1960-410: Is achieved in two-stroke GDI engines by injecting oil into the crankcase, resulting in a lower oil consumption than the older method of injecting oil mixed with fuel into the crankcase. Two types of GDI are used in two-strokes: low-pressure air-assisted, and high-pressure. The low-pressure systems—as used on the 1992 Aprilia SR50 motor scooter—uses a crankshaft-driven air compressor to inject air into
2058-456: Is also equipped with an on-demand water pump. Gasoline direct injection with a twin-scroll turbocharger will be used on the higher power versions. All Prince engines will share 84 mm (3.31 in) cylinder bore spacing, with 77 mm (3.03 in) bore. The 1.6 litre engine has a stroke of 85.8 mm (3.38 in). The engine features a two-piece "bedplate" aluminium crankcase for extra stiffness. The 1.4 L PSA EP3 and EP3C

Envirofit International , an American non-profit organisation, has developed direct injection retrofit kits for two-stroke motorcycles (using technology developed by Orbital Corporation Limited ) in a project to reduce air pollution in Southeast Asia. The 100-million two-stroke taxis and motorcycles in Southeast Asia are
2254-426: Is available which temporarily increases torque to 260 N⋅m (192 lb⋅ft) between 1700 rpm and 4500 rpm in gears 3 to 5. Applications: In 2010 Peugeot released the 1.6 THP engine ( EP6CDTX ) with 200 PS (147 kW) at 5500 rpm, maximum torque 275 N⋅m (203 lb⋅ft) at 1700 rpm. It featured direct injection , twin-scroll turbocharger and Valvetronic variable valve lift . It
2352-685: Is grammatically incorrect (in German, compound words must not contain spaces), which is why the grammatically correct form of the name, Bayerische Motorenwerke ( German pronunciation: [ˈbaɪʁɪʃə moˈtoːʁənˌvɛʁkə] ) has been used in several publications and advertisements in the past. Bayerische Motorenwerke translates into English as Bavarian Motor Works . The suffix AG, short for Aktiengesellschaft , signifies an incorporated entity owned by shareholders, thus akin to "Inc." (US) or PLC, "Public Limited Company" (UK). The terms Beemer, Bimmer and Bee-em are sometimes used as slang for BMW in
2450-406: Is more limited for GDI, since there is a shorter period of time available to inject the required quantity of fuel. In manifold injection (as well as carburetors and throttle-body fuel injection), fuel can be added to the intake air mixture at any time. However a GDI engine is limited to injecting fuel during the intake and compression phases. This becomes a restriction at high engine speeds (RPM), when
2548-412: Is now known as BMW Motorrad . Their first successful motorcycle after the failed Helios and Flink, was the " R32 " in 1923, though production originally began in 1921. 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
2646-633: Is set to end by 2016, and be replaced by its very latest 3 and 4 cylinder Engine family – BMW B37 , BMW B38 and BMW B48 . In 2015 it was announced, on the Hong Kong Stock Exchange , that BMW had signed an IPR deal with XCE. They will make the N18 TVDI engine in China for use in various Brilliance Automotive vehicles (JV Partner of BMW in China) and also for other China OEM's. PSA will continue to develop

BMW has a long history of motorsport activities, including: The global BMW Headquarters in Munich represents the cylinder head of a 4-cylinder engine . It was designed by Karl Schwanzer and
4214-490: The Prince engine beat, among others, the new BMW B38 engine which is replacing the Prince engine in the Mini and BMW lineups. The Prince family shares its basic block dimensions with the previous PSA TU engine family. Engineering design was directed by BMW using their Valvetronic variable valve lift system on the intake side, flow-controlled oil pump, timing chain, single belt drive of all ancillary units, composite camshafts and cylinder head produced by lost-foam casting. It

The first modern mass-produced turbocharged petrol engine was introduced in 2006 (from 1973 to 1975, BMW built 1,672 units of a turbocharged BMW M10 engine for the BMW 02 Series ), with most engines switching over to turbocharging over the 2010s. The first hybrid BMW
4410-465: The air, as would be the case in a conventional Otto cycle engine, but is instead injected during the compression stroke a little in advance of the spark. Hesselman engines could use a wide variety of fuels, including gasoline, but generally ran on conventional diesel fuels. During World War II, most of the German aircraft engines used GDI, such as the BMW 801 radial engine, the German inverted V12 Daimler-Benz DB 601 , DB 603 and DB 605 engines, and
4508-556: 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 Motorcycles for an undisclosed amount, which will not be revealed by either party in
4606-493: The black outline encircling the rondel. The logo is used for BMW's branding communications but it is not used on vehicles. The slogan 'The Ultimate Driving Machine' was first used in North America in 1974. In 2010, this long-lived campaign was mostly supplanted by a campaign intended to make the brand more approachable and to better appeal to women, 'Joy'. By 2012 BMW had returned to 'The Ultimate Driving Machine'. In 2023,
4704-828: The company was nearly taken over by rival Daimler-Benz. A large investment in BMW by Herbert Quandt and Harald Quandt resulted in the company surviving as a separate entity. Günther Quandt , was a well-known German industrialist, joined the Nazi party in 1933 and made a fortune arming the German Wehrmacht, manufacturing weapons and batteries. Many of his enterprises were appropriated from Jewish owners under duress with minimal compensation. At least three of his enterprises made extensive use of slave laborers, as many as 50,000 in all. One of his battery factories had its own on-site concentration camp, complete with gallows. Life expectancy for laborers
4802-523: The cylinder head. A low-pressure injector then sprays fuel into the combustion chamber, where it vaporizes as it mixes with the compressed air. A high-pressure GDI system was developed by German company Ficht GmbH in the 1990s and introduced for marine engines by Outboard Marine Corporation (OMC) in 1997, in order to meet stricter emissions regulations. However, the engines had reliability problems and OMC declared bankruptcy in December 2000. The Evinrude E-Tec
4900-444: The cylinder, which can force the ignitable parts of the mixture so far away from the spark plug, that it cannot ignite the air/fuel mixture anymore. Other devices which are used to complement GDI in creating a stratified charge include variable valve timing , variable valve lift , and variable length intake manifold . Also, exhaust gas recirculation can be used to reduce the high nitrogen oxide (NOx) emissions that can result from
4998-400: The desired distribution of fuel throughout the combustion chamber are either spray-guided , air-guided , or wall-guided injection. The trend in recent years is towards spray-guided injection, since it currently results in a higher fuel efficiency. In engines with wall-guided injection, the distance between spark plug and injection nozzle is relatively high. In order to get the fuel close to
SECTION 50
#17328756709435096-413: The distance between spark plug and injection nozzle is relatively high. However, unlike in wall-guided injection engines, the fuel does not get in contact with (relatively) cold engine parts such as cylinder wall and piston. Instead of spraying the fuel against a swirl cavity, in air-guided injection engines the fuel is guided towards the spark plug solely by the intake air. The intake air must therefore have
5194-425: The distance between spark plug and injection nozzle is relatively low. Both the injection nozzle and spark plug are located in between the cylinder's valves. The fuel is injected during the latter stages of the compression stroke, causing very quick (and inhomogeneous) mixture formation. This results in large fuel stratification gradients, meaning that there is a cloud of fuel with a very low air ratio in its centre, and
5292-454: The duration of each combustion cycle is shorter. To overcome this limitation, some GDI engines (such as the Toyota 2GR-FSE V6 and Volkswagen EA888 I4 engines) also have a set of manifold fuel injectors to provide additional fuel at high RPM. These manifold fuel injectors also assist in cleaning carbon deposits from the intake system. Gasoline does not provide the same level of lubrication for
5390-529: The early 1980s. Many BMW's are still produced in this layout, which is designated the R Series . The entire BMW Motorcycle production has, since 1969, been located at the company's Berlin-Spandau factory. During the Second World War, BMW produced the BMW R75 motorcycle with a motor-driven sidecar attached, combined with a lockable differential , this made the vehicle very capable off-road. In 1982, came
5488-418: The engine, therefore Junkers developed a GDI system to prevent this issue. A demonstration of this prototype engine to aviation officials was performed shortly before development ceased due to the end of World War I. The Hesselman engine is a hybrid engine design which was in production by various manufacturers from 1925 to 1951. In a Hesselman engine fuel is not injected during the suction stroke along with
5586-513: The exhaust system to meet emissions regulations. The use of NOx adsorbers can require low sulphur fuels, since sulphur prevents NOx adsorbers from functioning properly. GDI engines with stratified fuel injection can also produce higher quantities of particulate matter than manifold injected engines, sometimes requiring particulate filters in the exhaust (similar to a diesel particulate filter ) in order to meet vehicle emissions regulations. Therefore several European car manufacturers have abandoned
5684-464: The first successful prototype in 1894. An early prototype of a GDI engine was built in Germany in 1916 for the Junkers airplane. The engine was initially designed as a diesel engine, however it switched to being designed for gasoline when the German ministry of war decreed that aircraft engines must run on either gasoline or benzene. Being a crankcase-compression two-stroke design, a misfire could destroy
5782-465: The following years. The Mitsubishi GDI technology was also licensed by Peugeot, Citroën, Hyundai, Volvo and Volkswagen. The 2005 Toyota 2GR-FSE V6 engine was the first to combine both direct and indirect injection. The system (called "D-4S") uses two fuel injectors per cylinder: a traditional manifold fuel injector (low pressure) and a direct fuel injector (high-pressure) and is used in most Toyota engines. In Formula One racing, direct injection
5880-443: The fuel cools down the spark plug, immediately before it is exposed to combustion heat. Thus, the spark plug needs to be able to withstand thermal shocks very well. At low piston (and engine) speeds, the relative air/fuel velocity is low, which can cause fuel to not vaporise properly, resulting in a very rich mixture. Rich mixtures do not combust properly, and cause carbon build-up. At high piston speeds, fuel gets spread further within
5978-494: The fuel on the relatively cold piston cool down so much, that they cannot combust properly. When switching from low engine load to medium engine load (and thus advancing the injection timing), some parts of the fuel can end up getting injected behind the swirl cavity, also resulting in incomplete combustion. Engines with wall-guided direct injection can therefore suffer from high hydrocarbon emissions. Like in engines with wall-guided injection, in engines with air-guided injection,

The fuel being injected was described as being in vapour phase having been heated by the engine cylinder. The pressure of the fuel
6272-457: The head of the BMW Group. In January 2021, BMW announced that its sales in 2020 fell by 8.4 percent due to the impact of COVID-19 pandemic restrictions. However, in the fourth quarter of 2020, BMW witnessed a rise of 3.2% in its customers' demands. This recovery was supported by the company's adoption of widely accepted technologies and integration of third-party services such as Apply Pay and on-demand music. On 18 January 2022 BMW announced

6468-597: The homogeneous charge mode. The stratified charge mode creates a small zone of fuel/air mixture around the spark plug, which is surrounded by air in the rest of the cylinder. This results in less fuel being injected into the cylinder, leading to very high overall air-fuel ratios of λ > 8 {\displaystyle \lambda >8} , with mean air-fuel ratios of λ = 3...5 {\displaystyle \lambda =3...5} at medium load, and λ = 1 {\displaystyle \lambda =1} at full load. Ideally,
6566-574: The injector components as diesel, which sometimes becomes a limiting factor in the injection pressures used by GDI engines. The injection pressure of a GDI engine is typically limited to approximately 20 MPa (2.9 ksi), to prevent excessive wear on the injectors. While this technology is credited with boosting fuel efficiency and reducing CO 2 emissions, GDI engines produce more black carbon aerosols than traditional port fuel injection engines. A strong absorber of solar radiation, black carbon possesses significant climate-warming properties. In
6664-443: The intake and exhaust ports open during the exhaust stroke, in order to improve the flushing of exhaust gases from the cylinder. This results in some of the fuel/air mixture entering the cylinder and then exiting the cylinder, unburned, through the exhaust port. With direct injection, only air (and usually some oil) comes from the crankcase, and fuel is not injected until the piston rises and all ports are closed. Crankcase lubrication
6762-404: The logo is based on the image of an airplane propeller spinning in a blue sky. This myth likely stems from a 1929 BMW advertisement that depicted the logo superimposed on a rotating propeller. However, the logo predates that advertisement by 12 years. The current iteration of the logo was introduced in 2020, removing 3D effects that had been used in previous renderings of the logo while removing
6860-548: The misleading title of Forced Induction Engine whereas it was only the admission of the fuel that was forced. He revealed details of his prototype engine early in 1912, and the design was further developed by the large scale engine builder F. E. Baker Ltd during 1912 and the results displayed on their stand at the Olympia Motor Cycle show in November 1912. The engine was a high compression four-stroke motorcycle engine, with
6958-439: The most time to mix with the air, so that a homogeneous air/fuel mixture is formed. This mode allows using a conventional three-way catalyst for exhaust gas treatment. Compared with manifold injection, the fuel efficiency is only very slightly increased, but the specific power output is better, which is why the homogeneous mode is useful for so-called engine downsizing . Most direct-injected passenger car petrol engines use
7056-440: The ring is quartered blue and white, reminiscent of the coat of arms and flag of Bavaria (which in turn are based on the arms of the historic House of Wittelsbach , which ruled Bavaria for many centuries). The logo does not bear the distinctive lozenge shape found on the coat of arms, however, as local laws at the time it was introduced forbade the use of state coats of arms on commercial logos. A persistent myth claims that
7154-415: The shift from traditional port fuel injection (PFI) engines to the use of GDI technology will nearly double the premature mortality rate associated with vehicle emissions, from 855 deaths annually in the United States to 1,599. They estimate the annual social cost of these premature deaths at $ 5.95 billion. One of the early inventors trying gasoline direct injection was Dr Archibald Low who gave his engine
7252-548: The similar-layout Junkers Jumo 210 G, Jumo 211 and Jumo 213 inverted V12 engines. Allied aircraft engines that used GDI fuel injection systems were the Soviet Union Shvetsov ASh-82 FNV radial engine and the American 54.9 litre displacement Wright R-3350 Duplex Cyclone 18-cylinder radial engine. The German company Bosch had been developing a mechanical GDI system for cars since the 1930s and in 1952 it
7350-509: The spark plug, it is sprayed against a swirl cavity on top of the piston (as seen in the picture of the Ford EcoBoost engine on the right), which guides the fuel towards the spark plug. Special swirl or tumble air intake ports aid this process. The injection timing depends upon the piston speed, therefore, at higher piston speeds, the injection timing, and ignition timing need to be advanced very precisely. At low engine temperatures, some parts of
7448-476: The stratified charge concept or never used it in the first place, such as the 2000 Renault 2.0 IDE petrol engine ( F5R ), which never came with a stratified charge mode, or the 2009 BMW N55 and 2017 Mercedes-Benz M256 engines dropping the stratified charge mode used by their predecessors. The Volkswagen Group had used fuel stratified injection in naturally aspirated engines labelled FSI , however, these engines have received an engine control unit update to disable
7546-434: The stratified charge mode. Turbocharged Volkswagen engines labelled TFSI and TSI have always used the homogeneous mode. Like the latter VW engines, newer direct injected petrol engines (from 2017 onwards) usually also use the more conventional homogeneous charge mode, in conjunction with variable valve timing, to obtain good efficiency. Stratified charge concepts have mostly been abandoned. Common techniques for creating
7644-434: The throttle valve remains open as much as possible to avoid throttling losses. The torque is then set solely by means of quality torque controlling, meaning that only the amount of injected fuel, but not the amount of intake air is manipulated in order to set the engine's torque. Stratified charge mode also keeps the flame away from the cylinder walls, reducing the thermal losses. Since mixtures too lean cannot be ignited with
7742-450: The time, built the Austin 7 under licence from Dixi . The first car sold as a BMW was a rebadged BMW Dixi called the BMW 3/15 , following BMW's acquisition of the car manufacturer Automobilwerk Eisenach. Throughout the 1930s, BMW expanded its range into sports cars and larger luxury cars. Aircraft engines, motorcycles, and automobiles would be BMW's main products until World War II. During
7840-614: The ultra lean combustion. Gasoline direct injection does not have the valve cleaning action that is provided when fuel is introduced to the engine upstream of the cylinder. In non-GDI engines, the gasoline traveling through the intake port acts as a cleaning agent for contamination, such as atomized oil. The lack of a cleaning action can cause increased carbon deposits in GDI engines. Third party manufacturers sell oil catch tanks which are supposed to prevent or reduce those carbon deposits. The ability to produce peak power at high engine speeds (RPM)
7938-515: The use of ultra-lean mixtures that would be impossible with carburetors or conventional manifold fuel injection. The stratified charge mode (also called "ultra lean-burn" mode) is used at low loads, in order to reduce fuel consumption and exhaust emissions. However, the stratified charge mode is disabled for higher loads, with the engine switching to the homogeneous mode with a stoichiometric air-fuel ratio of λ = 1 {\displaystyle \lambda =1} for moderate loads and
8036-434: The war, BMW concentrated on the BMW 801 aircraft engine using as many as 40,000 slave laborers. These consisted primarily of prisoners from Nazi concentration camps , most prominently Dachau . Motorcycles remained as a side-line and automobile manufacture ceased altogether. BMW's factories were heavily bombed during the war and its remaining West German facilities were banned from producing motor vehicles or aircraft after
8134-481: The war. Again, the company survived by making pots, pans, and bicycles. In 1948, BMW restarted motorcycle production. BMW resumed car production in Bavaria in 1952 with the BMW 501 luxury saloon. The range of cars was expanded in 1955, through the production of the cheaper Isetta microcar under licence. Slow sales of luxury cars and small profit margins from microcars, meant BMW was in serious financial trouble and in 1959
8232-540: Was announced on 23 July 2002 with the first engines produced in 2006. The Prince engine project is not related to the Prince Motor Company . In late 2006, an extension of the cooperation between the two groups was announced, promising new four-cylinder engines, without further details. On 29 September 2010, it was announced by BMW that the turbocharged 1.6-liter version of the Prince engine would be supplied from 2012 to Saab for use in forthcoming models, primarily
8330-426: Was automatically added to the fuel mixture, obviating the need for owners to mix their own two-stroke fuel blend. The 1955 Mercedes-Benz 300SL also used an early Bosch mechanical GDI system, therefore becoming the first four-stroke engine to use GDI. Up until the mid-2010s, most fuel-injected cars used manifold injection, making it quite unusual that these early cars used an arguably more advanced GDI system. During
8428-511: Was commissioned to paint the BMW 3.0 CSL racing car driven by Hervé Poulain at the 24 Hours of Le Mans, which became the first in the series of BMW Art Cars. Since Calder's work of art, many other renowned artists throughout the world have created BMW Art Cars, including David Hockney , Jenny Holzer , Roy Lichtenstein , Robert Rauschenberg , Frank Stella , and Andy Warhol . To date, a total of 19 BMW Art Cars, based on both racing and regular production vehicles, have been created. BMW sponsors
8526-406: Was completed in 1972. The building has become a European icon and was declared a protected historic building in 1999. The main tower consists of four vertical cylinders standing next to and across from each other. Each cylinder is divided horizontally in its center by a mold in the facade. Notably, these cylinders do not stand on the ground; they are suspended on a central support tower. BMW Museum
8624-498: Was effectively replaced by the turbocharged three-cylinder BMW B38 engine. Applications: 75 kW version 100 kW version 125 kW version 130 kW version The turbocharged 1.6 litre versions used by Mini are called the Mini N14 and Mini N18 . The N18 succeeded the N14 starting from 2010 and had double Vanos. The N14/N18 engine uses direct injection ,
8722-455: Was first introduced in the Peugeot RCZ sport compact for the 2010 model year , where it generates 150 kW (204 PS). Applications: The 2012–2014 Mini John Cooper Works GP featured additional performance, with 160 kW (218 PS) at 6000 rpm and 280 N⋅m (207 lb⋅ft) of torque at 2000–5100 rpm from a larger turbo and engine internals. PSA has now released
8820-582: Was founded in 1916 as a manufacturer of aircraft engines , which it produced from 1917 to 1918 and again from 1933 to 1945 creating engines for aircraft that were used in the Second World War . The companies automobiles are marketed under the BMW, Mini and Rolls-Royce brands, and motorcycles are marketed under the BMW Motorrad brand. Also in 2023, BMW was the world's ninth-largest producer of motor vehicles , with 2,555,341 vehicles produced and in 2023
8918-489: Was introduced in 1925 for a low-compression truck engine. Several German cars used a Bosch mechanical GDI system in the 1950s, however usage of the technology remained rare until an electronic GDI system was introduced in 1996 by Mitsubishi for mass-produced cars. GDI has seen rapid adoption by the automotive industry in recent years, increasing in the United States from 2.3% of production for model year 2008 vehicles to approximately 50% for model year 2016. The 'charge mode' of
9016-474: Was introduced on the two-stroke engines in the Goliath GP700 and Gutbrod Superior. This system was basically a high-pressure diesel direct-injection pump with an intake throttle valve set up. These engines gave good performance and had up to 30% less fuel consumption over the carburetor version, primarily under low engine loads. An added benefit of the system was having a separate tank for the engine oil which
9114-513: Was introduced. It was subsequently brought to Europe in 1997 in the Carisma . It also developed the first six-cylinder GDI engine, the Mitsubishi 6G74 V6 engine, in 1997. Mitsubishi applied this technology widely, producing over one million GDI engines in four families by 2001. Although in use for many years, on 11 September 2001 MMC claimed a trademark for the acronym 'GDI'. Several other Japanese and European manufacturers introduced GDI engines in
9212-437: Was made compulsory for the 2014 season , with regulation 5.10.2 stating: "There may only be one direct injector per cylinder and no injectors are permitted upstream of the intake valves or downstream of the exhaust valves." There are additional benefits of GDI for two-stroke engines , relating to scavenging of the exhaust gases and lubrication of the crankcase. The scavenging aspect is that most two-stroke engines have both
9310-399: Was regulated at the fuel pump, and the amount of fuel admitted was controlled by mechanical means at the rotary admission valve. It seems this radical design wasn't taken further by F. E. Baker. Although direct injection has only become commonly used in gasoline engines since 2000, diesel engines have used fuel directly injected into the combustion chamber (or a pre-combustion chamber) since
9408-606: Was six months. While Quandt and BMW were not directly connected during the war, funds amassed in the Nazi era by his father allowed Herbert Quandt to buy BMW. The relative success of the small BMW 700 assisted in the company's recovery, allowing them to develop the New Class sedans. The 1962 introduction of the BMW New Class compact sedans was the beginning of BMW's reputation as a leading manufacturer of sport-oriented cars. Throughout
9506-560: Was the 2010 BMW ActiveHybrid 7 , and BMW's first mass-production electric car was the BMW i3 city car, which was released in 2013, (from 1968 to 1972, BMW built two battery-electric BMW 1602 Elektro saloons for the 1972 Olympic Games). After many years of establishing a reputation for sporting rear-wheel drive cars, BMW's first front-wheel drive car was the 2014 BMW 2 Series Active Tourer multi-purpose vehicle (MPV) . In March 2018, Daimler and BMW merged their mobility services. In August 2019, Oliver Zipse replaced Harald Krüger as
9604-415: Was then renamed to Bayerische Motoren Werke (BMW) in 1922. However, the name BMW dates back to 1913, when a company to use the name was founded by Karl Rapp initially as Rapp Motorenwerke . The name and Rapp Motorenwerke 's engine-production assets were transferred to Bayerische Flugzeugwerke in 1922, who adopted the name the same year. BMW's first product was produced for fighter aircraft of
