Construction

The P48 Turbo engine consists of approximately 2,000 individual parts. The engine's valve acceleration is 2,000 times faster than gravitational acceleration, or 400 times faster than the acceleration of a lunar rocket. The pistons in the BMW P48 Turbo accelerate from 0 to 100 km/h in less than a thousandth of a second – 1,200 times faster than a lunar rocket. Between them, all of the pistons in the engine cover a distance the equivalent of Munich to Cape Town over the course of a season. 2.8 million ignition sparks are generated in an engine over the course of a season. The water pump consumes roughly 18,000 litres in an hour. At this rate, it would fill a bathtub in 20 seconds. The full 600 hp of engine power is transferred to the drivetrain and rear wheels through screws. They weigh just 130 grams – the same as an cube of iron with a 2.5-mm edge. Over the course of a season, over of oil are pumped through the engine. During a season, enough heat for 500 sauna sessions is dissipated through the oil. For the engine's final assembly unit, 1,005 designs were drawn up. Placed side by side, they could cover the floor in a 250 m² apartment. In the interest of sustainability, these drawings were not printed, but were saved as PDF documents.
