I'm not surprised the US were all over it.One of the very first hybrid conversions was an investigation funded by DARPA, back in the mid-90s. They replaced the six-litre engine (and three-speed automatic gearbox) in a HMMWV with a pile of batteries, a motor in each wheel, and the 1.9L turbo-diesel unit out of the VW Golf. I don't think they lost that much in the way of payload.
The resulting vehicle could do 0-60 in half the time, get up steeper slopes than the original, and drive twice as far on the same amount of fuel. The latter being important in Afghanistan, because AIUI every gallon of fuel at a FOB cost forty gallons of fuel to deliver it...
So; curse those green gits. How dare they insist on wagons that are faster, quieter, and more efficient!
USMC had some really good gains without having to go down major platform procurement.*
As the US does not generally lean back from problems or innovation, it would be interesting to see where this project in the 90s foundered in between Proof of Concept and deliverables.
The last 20-25 years must have thrown up some better efficiencies on scalability of production, environmental endurance (hot/cold), survivability/robustness.
My point is mostly affected by the MoD approach to innovation and procurement, after all the UK has just procured a platform it started looking at in the 90s and as 8x8s go, this isn't massively innovative. (Its just fcuking massive!).
Colour me unsurprised if this green initiative doesn't survive initial enthusiasm and sinks into Abbey Wood procurement hell
*at the same time, UK initiated the Power FoB programme and was still searching for a prime to underwrite the thinking when it all went a bit glidepath for the door. Did the dissolution of DERA in to Qinetiq (cr@p Swiss Tony's) and DSTL (anorak central) fatally flaw the MoD's ability to think outside the box?
