Throughout its history, a few engines were used in the Land Rover Defender series: four-cylinder petrol engines, and four- and five-cylinder diesel engines. The 300Tdi, that our Land Rover Defender 110 is installed with, was the second-to-last engine introduced. It was smoother and quieter than the previous model, 200Tdi, but turned out to be not economical. In 1998 four-cylinder 300Tdi engines were replaced by five-cylinder Td5. They were more advanced and thus can be considered the best. But our Land Rover Defender was produced in 1995, so it is equipped with the latest engine for that time.
