The 2019 Subaru STI S209 has an intercooler sprayer, here's what it looks like when you activate it

The 2019 Subaru STI S209 gets a lot of features that distinguish it from your average WRX STI including wide body work, a giant wing, additional chassis braces and an extra 31 horsepower. It also brings back a performance gizmo that hasn't been featured in a U.S. market Subaru since 2007: the intercooler sprayer. As the name implies, it sprays cool water onto the air-to-air intercooler when pressing a button. In the case of the S209, that button is one of the paddles on the back of the steering wheel. That triggers the water nozzles hidden in the hood scoop to spray water. You can see what happens in the video below. Note that when the car is in motion, air would carry the spray farther back covering more of the intercooler. Now why would you want an intercooler sprayer? Well, the S209, like all WRX and STI models, uses an air-to-air intercooler to cool off hot air coming from the turbocharger on its way to the intake manifold. The cooler your air, the denser it is, meaning more oxygen to combine with fuel to turn into more power. The effectiveness of the intercooler depends partly on the temperature of the outside air flowing over the intercooler. If it's really hot out, it's not as effective. So spraying water onto the intercooler can counter this to ensure that the car is making maximum horsepower even in toasty conditions. This also means that although this may feel like some special secret performance-boosting weapon, it's really only effective in specific circumstances, and will just get you back to normal power, rather than make the car noticeably faster on the street. Long track days in the summer and after waiting in line at the drag strip or autocross are the kinds of situations where you could see power diminish due to hot air and a lack of moving air. Normal driving won't necessitate its use nor will driving in cool temperatures. In fact, the S209's owner's manual specifically says not to use the sprayer in temperatures below 41 degrees Fahrenheit because of the risk of frozen water in the tank. That brings us to another aspect of the intercooler sprayer: maintenance. In fairness, there isn't much to maintain, but if you want to use the system, you do need to keep the tank filled. It's located in the trunk where the spare tire would normally be. Inside of course is a water pump that connects to hoses that run water to the front. There is a warning light that will illuminate on the instrument panel if it runs low.

2020 Subaru Outback gets new-and-improved roof rack

The next-generation, 2020 Subaru Outback introduced at the New York Auto Show is quite obviously an evolution of the vehicle it replaces. Actually, we wouldn't be surprised if many folks can't tell the difference between the new and previous ones on the outside. There are many improved elements, however, and one of them is the Outback's unique roof rack system that returns for a third generation. As before, the roof rails swing inward to be their own cross bars. There's therefore no need to mount and remove separate crossbars, or alternatively, keep them on the car where they'll create noise and hurt fuel economy. Considering that so many Subaru owners mount things to the roofs of their cars (bikes, kayaks, gear boxes, skis, tents, etc.), this is one of those things than can really make the Outback stand out from the hordes of compact SUVs out there, including the Forester. The fact that the Outback's roof is lower, and therefore easier to lift thing upon, certainly helps. Again, the swing-in roof rails were there before. For the 2020 Outback, Subaru added sturdy arches at the edge of the roof rail assembly. Besides looking cooler than the rather bulky old set-up, these serve as large, easily accessed tie-down points for especially large items like kayaks. It seems like a simple thing, but it can actually make a difference in the way people actually use their cars.

Subaru brings sportier XV, Legacy and Levorg concepts to Tokyo Auto Salon

'Tis the season of the auto shows, boys and girls. We just came down from the techno-fest that was CES, we're set for the start of the Detroit Auto Show, in the UK they're holding the Autosport International racecar show, and in Japan they just opened the Tokyo Auto Salon. And true to form, Subaru was on hand with a wide assortment of tuned machinery. Aside from the competition-spec WRX and BRZ we brought you a few days ago, Subaru also spruced up some of its production models for the street. One of the most intriguing was the Levorg S that gives us an idea of what the conceptual Legacy wagon would look like in STI spec, complete with the requisite blue paint, red trim and STI badges, but also a full aero kit, 19-inch BBS wheels and carbon-fiber trim, plus an interior with bucket seats, flat-bottom rim and all the fixins. The Japanese automaker also showcased a version of the Legacy sedan dubbed Blitzen, decked out in bright red with a similarly upgraded aero kit, 19-inch alloys and a two-tone interior. The XV Crosstrek that was recently launched on this side of the Pacific as a special edition in bright yellow rolled in to the Tokyo salon in the same shade, but with upgrades similar to those on the aforementioned Levorg and Legacy show cars. The XV Sport concept wears upgraded aero, 17-inch wheels and a complementing yellow-trimmed back interior. Also on display was an even less subtle WRX S4 customized by Prova, done up in white but with an outlandish body kit, 20-inch Enkei alloys and a dropped suspension, as well as the new Forester tS.
