Subaru WRX S4 gets big power bump in Japan

A month after originally teasing it, Subaru is finally unveiling its WRX S4 model for Japan. It's a bit more than just a plush take on the sport sedan, because Subaru is fitting a more powerful version of the 2.0-liter, turbocharged boxer four-cylinder engine than we get on these shores.
The company says that S4 stands for "'Sports performance', 'Safety performance', 'Smart driving' and 'Sophisticated feel," and it certainly looks like this Rex ticks all of those boxes. The most surprising feature is the Japanese model's 2.0-liter turbo engine boasting 296 horsepower (221 kilowatts) and 295 pound-feet (400 Newton-meters) of torque in this application. That's quite a healthy upgrade over the 268 hp and 258 lb-ft that Americans get in the standard WRX, and it's even nipping at the heels of the 305 hp and 290 lb-ft from the STI with a 2.5-liter mill that we get over here.
While extra power is always welcome, enthusiasts might not be so thrilled that Subaru's Sport Lineartronic Continuously Variable Transmission is the sedan's only available gearbox. However, it offers a simulated eight-speed shifting mode when drivers notch the car into Sport# driving mode. Of course, the S4 also packs Subie's trademark all-wheel drive with Vehicle Dynamics Control and Active Torque Vectoring as standard.

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.

Toyota 86 most likely to get more power through more displacement? [w/poll]

The Sydney Morning Herald has spoken to Tetsuya Tada, chief engineer of the Toyota 86 (our version of it, the Scion FR-S, is pictured above), and they've been promised that more power is on the way. We've heard a lot of speculation about a more powerful Toyobaru since before the standard model was even launched. The only question now is how the power will be delivered, and among the engine concepts we've already heard about - turbo, supercharger, twin-charged, hybrid - is a new one: more displacement.
Tada said that an engine with more displacement than the current coupe's 2.0 liters is being tested alongside a turbocharged and a hybrid-assisted motor. The SMH cites "inside sources" as saying the displacement option is the one likely to get the go-ahead, and suggests increased bore and stroke will see the engine grow to 2.5 liters, horsepower to about 250 - a 50-hp increase over the present car.
While that's apparently the betting man's solution for the long-awaited increase in gumption, what happens with the next generation could be more wide open than we suspected. According to the report, Tada "hinted that [a successor] could be a radically different car, potentially dropping the boxer engine altogether." He said once they've sorted out the concept for the second generation car, then they'll sort out an engine. That's where a turbo option could come to market, perhaps the turbocharged four-cylinder Toyota is developing for the Lexus NX crossover or a hybrid system that uses a capacitor.
