Clicky here

It was a LR development (Project Storm) that only went to market about the time of BMW's take over of the company. The 2003 RR TD6 was a BMW motor from the X5.

Land Rover engines - Wikipedia, the free encyclopedia

I was under the impression that it is a Land Rover Built engine & funded by BMW, as at the time LR was owned by BMW.
The story was that BMW already had a 4 & 6 cylinder engines, so funds were drawn up to build a 5 cylinder that apparantly was already in the pipeline.
I am not to sure on the correctness of the story. But have heard this many times

From Internet Land Rover Club

The Td5 Diesel engine
"Storm"

This is a completely new engine. It's codename is Storm but the vehicles are labeled "Td5".

No, it's not an BMW engine, but an Rover design and, as it was almost finished when BMW took over, they agreed to continue work to fit it in Landrovers. It's an 5-cylinder engine, 2498 cc displacement, designed for 4x4 use. It has 300 Nm(manual box)/232 lb-ft of torque at 1950 rpm and 136bhp at 4200 rpm.

Definitely LR designed & built,most design work was done before BMW came along.

Yep, LR were developing a range of motors at the time with parts commonality in mind. TD4 for the Freelander, TD5 for the Disco and the TD6 for the Rangie. The Disco was a TD5 because thats all that would fit under the bonnet.

BMW pulled the pin on the TD4 and TD6 but kept the TD5 going, presumably because they didn't have a engine to fill that spot.

As said, it is a pure Land Rover motor, and to add to this there was no ECU available that would drive the TD5, so LR did all of that in house aswell.

a 3L td5,, that would b nice,,, how about a 4.2 td5-6,, that would be wicked,
i reacon if the td5 did make it to td6 it would of been one helll of a engine,,

some block design elements are borrowed from the tdi which borrowed them from the 2.25.

most of the work was done prior to BMW turning up on the scene BMW did contribute technical knowledge to the project primarily in the injector and ECU side of business.
