The Toyota AD engine family is a series of 16 valve DOHC inline-4 turbo diesel diesel engines with electronic common rail direct injection using an aluminium cylinder head and an aluminium cylinder block with cast iron liners derived from the petrol Toyota AZ engine. The AD engine is offered in 2.0 and 2.2 liter versions. These engines are produced mainly for Europe, but few are exported to other areas such as India or New Zealand.
