V8 and the option of the V12 engine was planned, but was never approved for production and was ultimately shelved around 2008. Other 16-cylinder engines The only other 16-cylinder automotive engines ever attempted were Bugatti's 1915 U16, Marmon's V16, the BMW Goldfisch V16 and Cizeta-Moroder's V16 (actually 2xV8). BRM fielded a V-16 in supercharged 1.5 liter form in 1950, which was powerful but unreliable. In addition, BRM developed an "H-16" engine (flat 8s stacked one atop another driving a third crank to the transmission) for the 1966 3 liter Formula One season. It was heavy and did not produce the expected amount of power. It was used by Lotus in the Model 43, and by BRM in its own F1 car. BRM abandoned the engine in 1967, replacing it with a V-12. A modern, quad-turbocharged W16 engine was used in the EB 16.4 Veyron built by the new Volkswagen-owned Bugatti in the 2000s as well as in its successor, the Bugatti Chiron. Porsche produced a flat 16 for use in their 917 model References External links "Sixteen-Cylinder Motor Latest Auto Wonder" Popular Mechanics, March 1930 V16 V16 engines
