Caught a glimpse of this whilst working up on a garage roof. Land Rover special vehicles badge is just visible.

An Esarco as said made as prototypes for MOD. Chassis numberwill be something like Sabateur, normally just behind nearside headlight. Was avaliable as 6x6 or 8x8, front axle steered on both but on the 8 wheeler rear axle steered as well. They weremade with V8 engines, Perkins Phazor engines and 6cyl VM. Transmission was either Auto or manual mated to normal L/R transfer box mated to another L/R transfer box to give 8 wheel drive. Propshafts and radius arms allways. Thing of a 110 transfer suspension on a 110 or 90 and overlap another in between the gaps. 

They were made as soft tops or crew cabs.

IIRC MWD werethe final company involved. 

Think army went for Supercats etc in the end.

 

They were very interesting to drive on and off the road.

Got an article somewhere about them will try and dig it out

the work 130 tipper, 2008 maybe puma engine? always seems to rev up slightly when in the low range, you lightly touch the throttle and the revs surge a bit, which is annoying when trying to reverse a trailer and the like, is this normal or is it something to try and fix.

thanks carl

Yes, this is normal on a Puma (and 2008 will be a 2.4 Puma). It is a feature known as "idle jack" which has the effect of raising the tickover speed of the engine when (a) the t-box is in low range, (b) the clutch is in, and (c) there is no throttle input from the pedal. The reason it was implemented is because it was found during testing that first gear low range was so low that engine braking on steep loose descents was sufficient to break traction and cause a loss of control. The "solution" was to raise the idle speed and hence reduce the amount of engine braking.

 

It can be a minor inconvenience under certain circumstances (such as precision manoeuvring of a trailer) but generally is just one of those things you get used to after a while.  Landrover forums are full of people asking how to turn it off, but there is no practical way to do so. The engine ECU doesn't use the high/low switch to determine the transfer gear, it does this based on matching engine and road speed, so really the only way to stop it is to do an ECU hack. Then of course you'd have the "problem" that idle jack was intended to overcome.

 

You will also find that, as in all post-TD5 Defenders and Discos, the mapping of throttle pedal deflection to fuel delivery changes in low range, so a greater movement of the pedal is needed for the same rev increase compared to high range.

 

You do get used to it after a while, but it is odd when you first drive a Puma after an earlier Defender.

cool thanks for the detailed reply, good to know its meant to be like that, its only slightly annoying when reversing a trailer. thanks again. carl

I specced a 110 D240 new Defender, fairly basic scuff protection and mud flaps, no extra gadgets that I recall and it still came to a gnat’s under £58k. That’s a lot of wedge a vehicle has got to earn back if it is going to be put to work!

What the heck do you get for the basic starting price then? a steering wheel?
