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.

Subaru teasing STI surprise for NYC show?

Subaru is no stranger to the Special Edition car, least of all where its vaunted WRX and STI are concerned. From Spec C to Prodrive to 22B, more than a handful of STI's around the world have been released as limited-run editions, often with stirring results. So, while we were more than a little bit surprised to see that big-wing crop up on the Subaru Twitter page today, we can't say as though its not true to the brand's history.
However, while most of the interesting WRX STI variants have been offered to Europe and Japan only, whatever is wearing that carbon-fiber-lipped wing is set to debut at the New York Auto Show this week.
We don't have a clue as to the precise nature of the car in front of that wing, save to say that it's likely based on the STI. We can guess, however that the extra vertical supports and the use of carbon fiber indicate a higher-performance version than currently exists. Anything from a racing application to some new goodies for the aftermarket are in the realm of possibility.

Subaru details BRZ tS, stops short of full-on STI

Fans of the sweet-handling Subaru BRZ awaiting some performance enhancements got their hopes up earlier this month when parent Fuji Heavy Industries dropped some teasers hinting at an apparent STI version, but as was subsequently suspected, the model in question - now revealed in full - stops short of being a full-on STI model.
What we're looking at here is the new Subaru BRZ tS, which incorporates a series of enhancements but leaves the engine alone. Available exclusively in the Japanese Domestic Market, the BRZ tS package includes a thicker driveshaft, a front lip spoiler, Brembo ventilated brake discs packed inside 18-inch wheels and a smattering of STI logos inside and out. STI has also upgraded the suspension components, retuned the stability control and exhaust note and enhanced the interior with some carbon and Alcantara touches. An additional GT package includes further upgrades, most noticeably the giant rear wing (made of carbon fiber) shown above, black-painted alloys and Recaro bucket seats.
Only 500 examples of the BRZ tS will be offered in Japan, with no more than 250 of those outfitted with the supplementary GT package. Here's hoping Subaru gives us a taste on this side of the Pacific as well - or better yet, maybe they'll quit joking around and give us the full-on STI already.
