Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

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.

Will more efficient tech mean higher prices for Subaru?

If the latest ruling by the California Air Resources Board holds, then Subaru at least must build a plug-in hybrid in the coming years to comply with the Golden State's regulations. Fuel economy looks to improve across the board for the brand, though, thanks to $780 million going into the development of cleaner powertrains for this fiscal year alone. However, buyers might have to pay more for a Subie in the future after this boost in green spending. "Related costs are going up more than expected, bringing the profit margin downward," Fuji Heavy Industries President Yasuyuki Yoshinaga said to the Nihon Keizai newspaper in Japan, according to Automotive News. "We are a small company. We do not benefit as much from economy of scale as bigger companies, so we will have to make up for the increased costs by raising our brand value." At the moment, Subaru's electrified lineup in the US comprises just the XV Crosstrek Hybrid, but the company is reportedly planning to add more. Plus, Subie also wants to make its internal combustion engines more efficient. According to Automotive News, all of the brand's mills are getting direct injection by 2016, and cylinder deactivation and lean combustion cycles are on track for 2020. Earlier rumors also suggested that the automaker might bring the turbocharged four-cylinder boxer to more products, as well. While these more efficient models might cost more, Subaru must carefully maintain the balancing act of introducing the technology and keeping sales growing. As of May 2015, the brand had 42 straight months of year-over-year growth in the US and had record sales in the country last year. The company has already decided to significantly boost production capacity at its Indiana factory in hopes of keeping the good times rolling.
