The Land Rover Td5 engine, a 2.5-litre, 5-cylinder turbodiesel used in the Discovery and the Defender had the same bore/stroke dimensions as the L-Series and used the same pistons, connecting rods and crankshaft dimensions. However, the Td5 was not simply a 5-cylinder L-Series. It used Lucas Electronic Unit Injection, instead of the L-Series' direct injection system, as well as a through-flow cylinder head and a very different ancillary equipment layout. The Td5 had been developed by the Rover Group under the codename 'Project Storm', which was originally to develop a replacement range of turbodiesels to replace the L-Series, with 4-, 5- and 6-cylinder engines of 2-, 2.5- and 3-litres respectively. When the Rover Group was taken over by BMW, they brought their own range of diesels which rendered the 2-litre and 3-litre Storm engines unnecessary. Only the Td5 entered production.
