Subaru punches out 15 millionth Boxer engine

It's a small milestone for our favorite manufacturer of gold-wheeled, all-wheel-drive sedans and crossovers, as Subaru announced that it has built its 15 millionth Boxer engine – a mere 49 years after it installed a tiny, horizontally opposed, four-cylinder mill in the 1966 1000 sedan. The milestone engine powers something a good bit larger than the 1000, which was (ironically considering Subaru today) the brand's first front-drive vehicle. Today's boxer, the so-called FB25 2.5-liter four, was built for the current Legacy and Outback. The 15 millionth Boxer hasn't been the brand's only accomplishment in 2015. The company built its 14 millionth Symmetrical all-wheel-drive system just last month. Subaru has only been at its trademark AWD system for 43 years, and with sales going the way they are, it seems only a matter of time before the Boxer engine is surpassed. Related Video:

Subaru uses a mime and a toy car to explain why it loves the boxer engine

I will freely admit to struggling with why Subaru continues to stubbornly employ a boxer engine design while so few other automakers do the same. After all, with twice the number of cylinder heads and cams as a traditional inline four-cylinder engine, a boxer four is more complex, more expensive to manufacture and more cumbersome to service with few tangible benefits. Until recently, the company's engines struggled to meet the fuel economy numbers of its competitors while offering no real boon in horsepower or torque. Subaru seems to recognize I'm not the only one scratching my head.
In order to help us non-believers understand what's what, the company has employed a pair of mimes, a toy car and a few clay engines to demonstrate the folly of every other automaker on the planet. Subaru says the boxer offers up a lower center of gravity than either an inline four-cylinder engine or a V6, which I will gladly concede. The company also says the design offers up smoother operation.
I'll offer just two counterpoints here. First, an engine with a low center of gravity is excellent, but when vehicles like the Forester, XV Crosstrek and Outback boast more ground clearance than most mainstream SUVs, that argument flies out the window. Second, anyone who's spent any amount of time behind the wheel of a vehicle equipped with an inline four and then proceeded to move into one propelled by a boxer can tell you the latter has all of the idling manners of a small tractor.

Next-gen Subaru WRX STI due next year with new engine, new platform

We just covered Japan's updated Subaru Impreza, which naturally has everyone wondering about a new WRX, the current fourth-generation on sale since 2014. According to a story in Japan's Best Car magazine, the fifth generation arrives late next year with a new platform and engine as part of the automaker's Japanese-market overhaul of the WRX STI, JDM-only WRX S4, and Levorg wagon. The STI is expected to switch from the current turbocharged EJ20 boxer-four to a direct-injection FA20 boxer-four engine with output of around 315 horsepower. Note, the Japanese-market WRX STI uses a 2.0-liter engine, the U.S version gets the 2.5-liter EJ257 with 310 hp. The U.S.-market WRX (sans STI) already uses the turbo FA20, but it makes 268 horsepower. The WRX STI will finally move to the Subaru Global Platform that the Impreza switched to in 2017, which will hopefully go a long way in improving ride comfort around town. The six-speed manual makes the switch as well. Best Car says the four-door's size won't change much, but the looks will crib from the Viziv concept - something everyone wants - with a design language called "Dynamic x Solid," U-shaped LEDs, and "greatly inflated front and rear fenders." Until then, the 2020 Subaru WRX STI will stick with its current architecture and another limited edition called the Series.White. A Torque News story says that as with the Series.Gray launched for the 2019 model year, the Series.White will be limited to 250 examples in WRX STI flavor, and 750 examples of the WRX. The Series.White gets a tonal neighbor on the palette for 2020, a new hue called Ceramic White that's exclusive to the WRX and WRX STI, which will omit any metallic or pearl effects in order to distinguish itself from the already-available Crystal White Pearl. The Series.White, as a special edition, will come with the requisite Crystal Black Silica badges, Recaro seats, Performance Package, suspension upgrades, folding side mirrors, and 19-inch black wheels.  The WRX S4 and Levorg will benefit from two brand new, downsized, direct-injection turbocharged engines in Japan, one of 1.5 liters, the other of 1.8 liters. Built around smaller, lighter engine blocks and boasted improved combustion efficiency, the 1.5-liter will produce about 148 hp, the 1.8-liter about 266 hp. Our non-STI WRX gets a 2.0-liter FA20 with 268 hp.
