Toyota WW engine

The Toyota WW engine family is a series of 16-valve DOHC inline-4 common rail direct injection turbo diesel engines produced by Toyota from 2011 through 2018. 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-liter (112 PS, 270 Nm) and 2.0-liter (143 PS, 320 Nm) versions.^[3]
