US Army Tests Subaru-Powered Hybrid Truck

Posted January 05, 2014 3:27 PM

From Autoblog:

The military has been studying the implementation of alternative drivetrains for years, a tiny sampling of which includes the diesel-electric hybrid technical hauler and L-ATV from Oshkosh Defense and the Aggressor from Quantum Technologies. There was also ADA Technologies' work with ultracapitors, General Motors' focus on fuel cells and the roll out of electric motorcycles for Special Forces. In the Ultra Light Vehicle (ULV) prototype vehicle pictured above, we have the latest developments in the Department of Defense's hybrid interest combined with a need to develop a lightweight replacement for the AM General Humvee. In 2010 the Office of the Secretary of Defense put the Army's Tank Automotive Research, Development, and Engineering Center (TARDEC) in charge of developing a personnel carrier that could "balance payload, performance and protection," and do so without exorbitant cost. Armored Humvees can weigh more than seven tons, and while the ULV is just under 14,000 pounds, the new vehicle can do a lot more with its weight. The Subaru turbodiesel under the hood puts out 175 horsepower and 260 pound-feet of torque. That's not much for pulling 13,916 pounds, so it's assisted by two Remy 410HVH HT electric motors each capable of adding 268 continuous hp and 369 peak hp, along with 844 lb-ft of continuous torque or 1,221 ft-lbs at peak. They're only limited by the 14.2 kWh lithium-ion battery rated at 65 kW of continuous power and 180 kW of peak power, but still, TARDEC says the ULV can do 21 miles on electric power and on the flats has a combined range of 337 miles at 35 mph.

Fitted with ELockers. "When locked the Eaton ELocker performs as a full locker, capturing 100% of available torque and sending it equally to both ends of the axle." - from the site. Amazing how few people understand diffs & 4WD.

268 continuous HP for what, 10 minutes until the battery runs flat? Or does the battery account for 11,000 pounds of this hog?

I didn't know that Subaru was a source of energy. What is the unit of measurement for this power source?

garyrich2000 you are one very perceptive person, I myself assumed the same as each of the persons responding with their opinions. Despite the excellence of the Subaru designed engine the 'maximum weight or load carrying capacity' should be the 1st area of compromise, a reduction in the massive weight of 'so many components and manufactured inner content' will reflect in a better performance when it comes down to the overall torque delivery. Seems to me that using the available 'off the shelf manufactured componentry' needs some serious re-evaluating.

Regards,

An Australian perspective.

'....Armored Humvees can weigh more than seven tons, and while the ULV is just under 14,000 pounds, the new vehicle can do a lot more with its weight.....'

.

I wonder if they are actually fooling many people using this tactic of switching units in the weight comparison and using a name that claims it to be 'Ultra Light'.

.

My understanding it that the standard armored Humvee comes in at 14,300 lbs, meaning the even using the ULV designation the weight reduction falls well short of even just 3%.

.

Sad.

It is no surprise that the decision makers don't bother to consider these vehicle manufacturers as that General Motors will lobby successfully no matter the better designed vehicle, nor even the cost of whatever military vehicle. This is not untypical of the American Military Machine's approach, as the cost to the American taxpayer is the very least consideration that will effect the high ranking office-dwelling Pentagon General's in their decision making.

At the end of the day the War Machine will enable its means to do as they themselves wish to do

"At the end of the day the War Machine will enable its means to do as they themselves wish to do"

Or you're dead. ;-)

Interesting phrase is 'Bald Eagle it' which means to find at least one subcontractor in each state - no matter how small the subby and their job, no matter how ridiculous the project.

Ensures a fast pass through guvmin -

'net government is coming!

"...At the end of the day the War Machine will enable its means to do as they themselves wish to do..."

.

If this were true, the huge expense would be somewhat easier to accept. Unfortunately, not only is the bill egregiously high, but the War Machine is not enabled with means to do as they wish.

.

Having fighters that suffocate pilots is not something the War Machine wishes.

.

Having stealth that isn't really all that hard to track is not something the War machine is gung ho about.

.

Creating a pattern that is yearning to become a legacy of introducing new latest and greatest next generation equipment that, though a combination of cost over-runs and performance under-shoots, whittles a planned run of tens of ships or hundreds planes or any number of others.... down to just a few initial prototypes, thereby setting records for the highest expenditure per unit in their respective classes for less than stellar now-oddball equipment, is not something the War Machine becomes giddy with anticipation about.

.

If the end result was closer to what it had been sold as, the bill would still be high, but at least we would be getting what we were told we are paying for.
