Luxury cars usually have a V12 engine, which is a V-shaped 12-cylinder engine.

W-type engine is a patented technology of Volkswagen. Only Volkswagen, the brand owned by Volkswagen, is using W-type engine. At present, there are mainly W12 (used for A8 6., Phaeton 6. and Bentley Continental Series) and W16 (used for Bugatti Veyron), and previously there was W8 (used for the top Passat of the previous generation), but now it is gone.

strictly speaking, the W-type engine belongs to the V-type engine, but the cylinders on both sides of the V-type engine are subdivided into two groups, which look like "W" from the side, hence the name. Volkswagen W12 engine is actually made up of two VR6 engines with small included angle. Its biggest advantage is compact structure and easy layout, which is beneficial to the optimization of engine compartment space, but its disadvantage is that the structure is too complicated.
