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.

2015 Subaru WRX: Introduction

"As far as street-legal rally cars go, there's still nothing better than a WRX." I wrote that line following my first drive of the 2015 Subaru WRX late last year - one of the better motoring experiences I had in 2013. Sure, a particularly involving drive route helped, but I don't want to sell the new Subaru short: it's a seriously good car - easily one of the sharpest, best-driving little turbos available today.
When I drove the even hotter 2015 WRX STI in January, it was a similar love-fest. The STI is infused with all of the WRX's greatness, but it's sharper, meaner, and on good roads (and race tracks), the winged wonder is really outstanding. But because of its higher price tag, less forgiving suspension tuning, and only marginal performance increases, I'm convinced that the STI isn't the best WRX for the money. And much as I love it, I just don't think I'd ever buy the STI over its more sedate sister (though I totally understand why others might).
So when it came time to add a new long-term car to the Autoblog fleet, many votes were cast in favor of the WRX. There was a lot of debate about whether or not to get the standard version, or the mightier STI. But at the end of the day, my argument that the basic WRX is the better daily driver - nee, one of the best all-around, all-weather performers money can buy - carried the day.

2015 Subaru Impreza gets visual tweaks, added refinement

While our love for the Subaru Impreza is mostly reserved for its turbocharged WRX and STI models, there's still a fully competent, well-rounded package in the base model, now in its fourth generation. In order to keep it competitive, Subaru has given the Impreza a light refresh for the 2015 model year, and while the car hasn't changed much mechanically, there are a number of thoughtful updates in store for the revised model.
Most noticeably, the front end has been touched up, with a revised lower fascia that's a bit more aggressive than before, nicely incorporating foglamps on higher-end models. Around back, not much has changed, though there's a new lip spoiler on sedan models to improve aerodynamics. Inside, a new infotainment system is available, with a seven-inch color touchscreen, and Subaru's EyeSight driver assistance package can now be had on the Limited models. There's also an updated instrument cluster with an LCD color display, new door and shifter trim, a standard rearview camera, and a few tuning enhancements that allow for a quieter ride, according to Subaru's release.
Under the hood is the same 2.0-liter boxer four-cylinder engine as before, with 148 horsepower on tap, mated to either a five-speed manual or continuously variable transmission. Subaru notes that there's a quicker ratio for the electronic power-assisted steering (that's a good thing), and reminds us that the Impreza is still pretty fuel-efficient considering its standard all-wheel drive, able to achieve 28 miles per gallon in the city, 37 mpg highway and 31 mpg combined.
