Is Subaru close to ditching 6-cylinder engines?

Despite niche outliers like the 6.2-liter supercharged Hellcat V8 and 7.0-liter V8 in the Chevrolet Camaro Z/28, we live in an era where small-displacement, turbocharged engines are becoming the norm. In many model lineups, a boosted four-cylinder now holds the place that a six might have just a few short years ago. At least in some markets, Subaru could be the next automaker to follow this path by axing its 3.6-liter boxer six-cylinder. Granted, that's not as much of a leap for Subie as some other automakers because the Japanese brand is already closely associated with turbocharged four-cylinder engines. The company's six-pot boxer is currently only offered in the Legacy and Outback in the US. Australian website CarAdvice spoke with Subaru deputy general manager of engineering Yoichi Hori about the company's future powertrain plans at least for Down Under. "Our research said the six-cylinder model is decreasing in the world. So that's why probably the future, many companies take the smaller displacement with a turbocharger, or diesel, or hybrid," said Hori to CarAdvice. He was also specific about which engine he had in mind. "In terms of the body size, a 2.0-liter with a turbocharger is enough, I think," he said. Hori said that the automaker stuck with the boxer-six for so long because of the turbocharged four-cylinder's higher maintenance costs. Slotting Subaru's 2.0-liter turbocharged boxer four-cylinder into the Legacy and Outback seems easy to imagine. After all, the mill already does duty in different tunes in the Forester and WRX in the US. Keep in mind, though, that Hori's words are aimed at the Aussie market. A rumor from earlier this year speculated the company's midsize models might get a smaller displacement six and the turbo four for some trims.

2015 Subaru BRZ tS First Drive [w/video]

The Subaru BRZ is a brilliant driver's car: lightweight, rear-wheel-drive, tactile, nimble and fluid at speed. In terms of qualities that allow for dazzling point-to-point performance, it lacks only power and intense mechanical grip. In the US, options for tuning the BRZ to amplify its strengths or diminish its weaknesses are mostly found in the aftermarket. In Japan, meanwhile, driving enthusiasts can start with the factory-tuned model you see above: the BRZ tS. Designed and built with the engineering prowess of Subaru Tecnica International, the limited-edition tS is tuned for track competence over and above that of the base model. The intent of the tS wasn't lost on me as I stared over the front fender towards Turn 1 at Japan's Suzuka Circuit. Not just a proper place to test STI's claims of increased handling brilliance for its BRZ tune, but a perfect one. Suzuka is challenging – fast and technical in equal measure – and a playground for sorting out the margin of improvement from the standard that BRZ I know so well. Wait, Why Am I Here? Of course, Subaru didn't invite me and a half-dozen other motoring journalists to Japan for an academic exercise in JDM hotness. We were there at the behest of STI, as a first step in what will undoubtedly be a deliciously drawn-out expansion of the performance brand in North America. STI started life as the motorsports division for Subaru-parent Fuji Heavy Industries. But chances are good that you, like me, first encountered the three-letter-logo as a Cherry Blossom Red punctuation mark at the end of a WRX road or rally car. The world came to know STI through Subaru's 1990s WRC dominance and prominence in the Gran Turismo franchise. But outside of Japan the significance of the initials was known more as the designation of the top-dog Impreza, rather than a motorsport and performance engineering unit. The company is set on changing that and building STI into a performance brand that's as easily recognizable in America as M and AMG are today. That message was delivered a body in the STI Concept car at the New York Auto Show earlier this week, but as I mentioned then, we don't expect Subaru to turn up with a production-ready BRZ STI next year. First STI will deploy its parts catalog to the US, removing the half-hearted Subaru Performance Tuning parts business in the process. Next, according to a vague timeline presented in Japan, Subaru will offer a car like the tS to US customers in approximately 18 months.

Subaru confirms 2015 WRX STI to grace Detroit show stand

Now that we've seen and driven the 2015 Subaru WRX, it's time to set our sights on the car's more powerful and traditionally massively winged counterpart: the STI. And while a few rumors about the new STI have already leaked, Subaru today confirmed that we'll be seeing the hotter 'Rex at the Detroit Auto Show later this month. Hot diggity.
Last we heard, the new STI will still use a turbocharged, 2.5-liter boxer-four (remember, the standard WRX uses a version of the 2.0-liter engine found in the Forester) producing something like 300 horsepower and 290 pound-feet of torque. What's more, don't expect the STI to hatch a five-door variant - Subaru recently told us that there are no plans to offer anything beyond a sedan bodystyle for both versions of the WRX. Sad trombone, we know.
That said, if our time with the 2015 WRX sedan is anything to go by, this new STI should be pretty rad. The new WRX is significantly sharper than the outgoing model (in terms of driving dynamics, anyway - it's still a pretty ugly little thing), and we fully expect the STI to be a bulgier, harsher, more powerful and aggressive version of the already awesome street-legal rally car. We're just hoping it will be offered with WRC-correct gold wheels, too.
