The Toyota WW engine family is a series of 16 valve DOHC inline-4 turbo diesel engines with common rail injection. These engines are based on the BMW N47,[1] modified for use in Toyota vehicles, starting with the Verso in 2014. This involved the development of a number of new components, including engine mounts, a dual-mass flywheel, a new gearbox housing and gearing and a stop/start system to further improve efficiency and reduce emissions.[2] The WW engine is offered in 1.6 (112 PS, 270 Nm) and 2.0 liter (143 PS, 320 Nm) versions.[3]
