Td5 Defender / Td5 Discovery Power difference?

[BlackAdder]

Has anyone else out there noticed the different power output from the Td5 Defender and the Td5 Discovery?

Both are the 2495cc but there is a difference in the spec'd power output:

Defender 90 kW @ 4200 rpm
Discovery 101 kW @ 4200 rpm

Any ideas why?

I noticed it a while ago, landrover detuned the engine for the defender apparently.

Why? Don't aske me, I don't know why you would bother.

better fuel economy ?

G'Day Pheonix, I agree, don't know why they would do that.

Hey Incisor, I can understand the better fuel economy, but at the cost of 11 kW (more than 10%), does not make sense. Would be nice to be able to switch between 90 and 101 kW at will, sort of like a turbo boost controller :wink:

Anyway, cheers.

I think it is to do with the size of the intercooler. TDI defenders were always quoted at less kw as well.

[Pedro_The_Swift]

maybe its the other way around,,
maybe they increased the KW's because of the extra weight in the Disco's

Thanks for that ShaunP, it's something I had not considered.

Theres a dofference between the Manual and auto Discovery TD5 as well (101kw/300Nm - manual, 101kw/340Nm). I think its something to do with the amount of torque the R380 can handle, where the auto can take more. I originally thought the discovery had the higher power less torque for better on road performance where the defender had less power but more torque for better off road performance................

I also heard it had to do with the auto box. Apparently the lower figure is suppose to enhance the drivability of the manual Defender???? (or so a LR dealer once told me)

Another one of those great Landrover mystery's.
