Thread: Disco 3.0Lt v Jaguar 3.0Lt

What are the torque differences? Maybe the D4 has been tuned for more torque?

Michael

You can get a re-map for the D4 3.0L that puts out 720Nm of torque not sure what the power increase was. I would say difference is due to mapping, D4 needs to cope with different qualities if fuel in a greater range of conditions so is detuned.

Hi Michael, the torque is exactly the same. Not sure why the Disco is de-tuned for power??

But is the torque curve the same?

Yes, both have 500Nm available from idle. Not sure beyond this, but I assume it would be the same.

The Land Rover variants are probably de-tuned slightly in the interests of economy. A D4 is a lot heavier than a Jag, so to get reasonable consumption figures, they may have decided to sacrifice a bit of power.

That makes sense Gordon. Another story I heard is that when testing the D4, they found that by reducing the power output, it was not only better on fuel, but ran cooler as well????
