BMW 7 Series (G11)
The sixth generation of the BMW 7 Series consists of the BMW G11 (normal version) and BMW G12 (long-wheelbase version) luxury saloons. The G11/G12 generation has been produced by BMW since 2015, and is often collectively referred to as the G11. The G11 was unveiled on 10 June 2015 at BMW's headquarters in Munich. An official public reveal took place at the 2015 International Motor Show Germany. This generation of the 7 Series is the first car lineup of BMW to be based on the CLAR platform. The CLAR platform adopts technology first introduced in BMW i models, namely the introduction of carbon-fibre-reinforced polymer as structural chassis components. Long-wheelbase cars have the letter "L" in their model name. As part of BMW's strategy of introducing plug-in hybrid variants for all future car models, the normal and long-wheelbase models were available with hybrid powertrains as 740e and 740Le in 2016.

Front-engine, Four-wheel-drive Layout
In automotive design, an F4, or front-engine, four-wheel drive (4WD) layout places the internal combustion engine at the front of the vehicle and drives all four roadwheels. This layout is typically chosen for better control on many surfaces, and is an important part of rally racing, as well as off-road driving. In terms of racing purposes, whether it be on-road or off-road, can be described as follows, A team that pursues the Weak LS4WD architecture will minimize the development cost of the front-wheel drive system at the expense of having a larger rear powertrain. The Weak architecture produces a vehicle with a large powersplit between the front and rear powertrains, while the Strong architecture recommends a vehicle with more similar power and torque requirements for the front and rear. Most four-wheel-drive layouts are front-engined and are derivatives of earlier front-engine, rear-wheel drive, or front-engine, front-wheel drive designs. The first origins of it were in ...

Plug-in Hybrid
A plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into an external electric power source, in addition to internally by its on-board internal combustion engine-powered generator. Most PHEVs are passenger cars, but there are also PHEV versions of commercial vehicles and vans, pickup truck, utility trucks, buses, trains, motorcycles, mopeds, and even military vehicles. Similar to battery electric vehicle, all-electric vehicles (BEVs), PHEVs displace greenhouse gas emissions from the car tailpipe exhaust gas, exhaust to the power station generators powering the electricity grid. These centralized generators may be of renewable energy (e.g. solar power, solar, wind power, wind or hydroelectric) and largely emission-free, or have an overall lower emission intensity than individual internal combustion engines. Compared to conventional hybrid electric vehicles (HEVs), PHEVs have a larger battery pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary a ...

BMW N74
The BMW N74 is a twin-turbo V12 petrol engine which replaced the N73 and has been produced since 2008. It is BMW's first turbocharged V12 engine and is also used in several Rolls-Royce models. Design Compared with its naturally aspirated BMW N73 predecessor, the N74 features twin-turbochargers. The turbochargers are located on the outside of the engine and use a boost pressure of . In its base configuration the engine has a compression ratio of 10:1 and a specific fuel consumption of 245 g·kW−1·h−1 As per its predecessor, the N74 has direct injection, DOHC and variable valve timing (called double-VANOS by BMW). However, the N74 does not have variable valve lift (called Valvetronic by BMW). The N74 marked BMW's first use of an 8-speed automatic transmission, in the form of the ZF 8HP90. Versions N74B60 This initial version of the N74 has a bore of and a stroke of . The redline is 7000 rpm and the compression ratio is 10.0:1. Applications: * 2008 ...

Twin-turbo
Twin-turbo (not to be confused with a twincharger setup, which is a combination of a supercharger and a turbocharger) refers to an engine in which two turbochargers work in tandem to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes. Types and combinations There are three types of turbine setups used for twin-turbo setups: * Parallel * Sequential * Series These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups): * Compound Compressors * Staged Compound Compressors * Staged Sequential Compressors * Parallel Sequential Compressors * Parallel Compressors Parallel A parallel configuration refers to using two equally-sized turbochargers whi ...

V8 Engine
A V8 engine is an eight-cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. The first V8 engine was produced by the French Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient, lower capacity engines, or hybrid and electric drivetrains. Design V-angle The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations; however, the downside is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BMW N63
The BMW N63 is a twin-turbocharged V8 petrol engine which has been in production from 2008 to present. The N63 is the world's first production car engine to use a "hot-vee" layout, with the turbochargers located inside the "V" of the engine. It is also BMW's first turbocharged V8 engine. The N63 replaced the BMW N62 (a naturally aspirated V8 engine) and was first used in the 2008 X6 xDrive50i. The S63 engine is the BMW M high-performance version of the N63. Alpina versions of the N63 are used in various F01 7 Series, F10 5 Series, G11 7 Series, G16 8 Series and G30 5 Series models. Design The airflow path through the engine uses a "hot-vee" layout, where the exhaust manifolds and turbochargers are located between the cylinder banks (on the "inside" of the V8) and the intake manifolds are located on the outside of the engine. This is opposite to the traditional layout for a V8, where the intake is inside the "V" and the exhaust manifold is on the outside. The hot-vee la ...

Inline-six Engine
The straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or less cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common from the 1960s and by the 2000s most straight-six engines had been replaced by V6 engines. An exception to this trend is BMW which has produced automotive straight-six engines from 1933 to the present day. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Straight-six engines are typically produced in displacements ranging from , however engines ranging in size from the Benelli 750 ...

BMW B58
The BMW B58 is a turbocharged straight-six engine, which began production in 2015. The B58 replaced the N55 and was launched in the F30 340i. The B58 is part of BMW's new modular engine family, each engine using a displacement of per cylinder, following the B38 and B48 engine. The B58 engine was named to Ward's World's 10 Best Engines 4 times, in 2016 (installed in the 340i), 2017 ( M240i), 2019 ( X5) and 2020( M340i). The S58 engine, which was released in early 2019, is the high-performance version of the B58. Design Compared with its BMW N55 predecessor, the B58 features a 20% increase in boost pressure, a closed-deck engine block design, an increase in compression ratio to 11.0:1 and a slight increase in displacement from with added weight of . The turbocharger is a twin-scroll design, for more efficient power delivery with less turbo lag and more power than a conventional single turbocharger, as well as for weight and space saving benefits.

Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
Inline-four Engine
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...
