The first application of the Volkswagen W12 was the 2001 Volkswagen W12, a mid-engined concept car which set the 24‑hour world endurance record in 2001 with a distance of 7,085.7 kilometres (4,402.8 mi) and an average speed of 295 km/h (183 mph). The first production car to use the W12 engine was the 2001 Audi A8 (D2). [4]
A W12 engine is a twelve-cylinder piston engine where either three banks of four cylinders, or four banks of three cylinders are arranged in a W configuration around a common crankshaft. W12 engines with three banks of four cylinders were used by several aircraft engines from 1917 until the 1930s.
103 to 125 kW variants — multi-ribbed belt-driven fifth-generation Eaton Roots-type positive displacement supercharger operated by a magnetic clutch integrated in a module inside the water pump, internal step-down ratio on the input end of the synchronisation gear pair, and KKK turbocharger with integrated wastegate connected in series ...
An evolution of the 1964 DOHC prototype “XJ13” engine, the Jaguar V12 engine is a family of SOHC internal combustion V12 engines with a common block design, that were mass-produced by Jaguar Cars for a quarter of a century, from 1971 to 1997, mostly as 5.3‑litres, but later also as 6‑litres, and 7‑litre versions that were deployed in racing.
A four-stroke V12 engine has even firing order at V-angles of 60, 120, or 180 degrees [1] [unreliable source] Many V12 engines use a V-angle of 60 degrees between the two banks of cylinders. [2] V12 engines with other V-angles have been produced, sometimes using split crankpins to reduce the unbalanced vibrations. The drawbacks of V12 engines ...

The W12, whilst still highly competitive, was not as dominant as its predecessor either in pre-season testing or at the 2021 Bahrain Grand Prix.The regulation changes designed to reduce downforce produced by the floor area are said to have compromised lower rake designs, like the W12, more than higher rake designs like that of Red Bull RB16B, along with the banning of the DAS system.
In computer programming, duplicate code is a sequence of source code that occurs more than once, either within a program or across different programs owned or maintained by the same entity. Duplicate code is generally considered undesirable for a number of reasons. [ 1 ]
