The cylinders of a bank are offset in a tandem arrangement and positioned at a very narrow angle of 15°. The compact W engine was made possible by arranging two banks at an angle of 72°. To provide adequate space for the pistons in the bottom dead centre range, it was necessary to offset the crankshaft drive. This means that the cylinders are offset by 12.5 mm outwards relative to the centre of the engine (crankshaft fulcrum).
