We will go for the Discovery 4 SD V6 3.0L, inlieu of the LC200 and Discovery 4 2.7L.
Comparing it to the 2.7L, there is a big difference in torque, and with the different gearbox and brakes etc, I agree the 3.0L is the better option.
When comparing the 3.0L to the Landcruiser with its 4.5L engine, the torque is 600 vs 650 and power to weight ratio 185 vs 197. I don't consider the differences to be terribly significant. Especially when coupled with the standard towing features of the Discovery.
Looking at the ratio between the rpm at max power, to the rpm at max torque, I get 1:2 vs 1:1.6 (Toyota state torque at 650 @ 1600 rpm to 2600 rpm. I took the middle at 2100 to base my calculations). Using Toyotas figure of 1600, you get a ratio of 1:2.1 (1 to 2 point 1) or using 2600, a figure of 1:1.3. Again the Discovery 3.0L is at 1:2.
Just in closing, again I appreciate all of the comments and advise that has been provided to me through this Forum.
Best wishes to everyone.
