The BMW Goldfisch is a SOHC 32-valve V16 6.7-litre prototype automotive piston engine based on the BMW M70 V12 engine.
Development started in the late 1980s. The engine was built to demonstrate the maximum potential of the small cylinder displacement engine family. Also, a three cylinder model of the same engine family was made to set a minimum. Development started on July 8, 1987, and by the beginning of 1988 the engine was ready. It was put on a dynamometer in January and February 1988. Afterwards, it was installed in a modified long wheelbase BMW 7 Series (E32), and the first driving tests were made in May 1988. On July 7, 1988, the engine was presented internally within BMW.
To prevent an ″arms race″ with other engine manufacturers, the V16 was never put into mass production. Additionally, a higher-performance version of the M70 engine, the S70B56 installed in the BMW 850CSi, produced 380 PS (279 kW) and 56.1 kp·m (550 N·m) of torque, almost reaching the power output of the V16.
The engine design virtually copies the BMW M70 V12 layout but with 4 more cylinders added.
