US Army tests Subaru-powered hybrid truck

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.

Subaru Viziv 2 presages Tribeca replacement with diesel hybrid tech

Subaru is in the middle of a new product bonanza. It has recent replacements for the Impreza and Forester at dealers, and soon we're getting the WRX, Legacy and if rumors are right the new Outback as well. Now, there are rumblings that there could be two more models from the Japanese brand on the way with styling inspired by the Viziv 2 concept from the Geneva Motor Show.
According to a company insider speaking with Motor Trend, the crossover concept shows the way for the brand's future design language. The shape would be used on a smaller CUV that is still being kept quite secret, and a second, larger one that would replace the recently axed Tribeca. The bigger model is the first priority and is planned as a new technology showcase.
It's rumored to use a turbodiesel, four-cylinder boxer engine that would be boosted with one electric motor on the front axle and two at the rear, with a plug-in hybrid system sourced from Toyota. It should provide a great mix of torque and fuel economy. A smaller flat-six engine would be a second powertrain option. Though the Viziv 2 concept only seats four, the production version would probably offer three rows.

Subaru uses a mime and a toy car to explain why it loves the boxer engine

I will freely admit to struggling with why Subaru continues to stubbornly employ a boxer engine design while so few other automakers do the same. After all, with twice the number of cylinder heads and cams as a traditional inline four-cylinder engine, a boxer four is more complex, more expensive to manufacture and more cumbersome to service with few tangible benefits. Until recently, the company's engines struggled to meet the fuel economy numbers of its competitors while offering no real boon in horsepower or torque. Subaru seems to recognize I'm not the only one scratching my head.
In order to help us non-believers understand what's what, the company has employed a pair of mimes, a toy car and a few clay engines to demonstrate the folly of every other automaker on the planet. Subaru says the boxer offers up a lower center of gravity than either an inline four-cylinder engine or a V6, which I will gladly concede. The company also says the design offers up smoother operation.
I'll offer just two counterpoints here. First, an engine with a low center of gravity is excellent, but when vehicles like the Forester, XV Crosstrek and Outback boast more ground clearance than most mainstream SUVs, that argument flies out the window. Second, anyone who's spent any amount of time behind the wheel of a vehicle equipped with an inline four and then proceeded to move into one propelled by a boxer can tell you the latter has all of the idling manners of a small tractor.
