Subaru files for S209 trademark in the U.S.

Last week, Subaru filed an application with the U.S. Patent and Trademark Organization to trademark "S209." The paperwork indicates Subaru would like to apply it to "automobiles, structural parts, and structural fittings therefor," and "floor mats for automobiles." An application doesn't mean anything, but the obvious deduction would be that Subaru is thinking about another special edition Impreza WRX STI for the U.S. market, one that brings a taste of JDM-only nomenclature our way. The S appellation is as serious to the Subaru Tecnica International division as STI is to Subaru overall. The STI boffins have rolled out these extra special modes since the S201 STI in 2000, the Japanese market reaping a new S harvest every couple of years. Our last distant visions of such were the S207 shown at the 2015 Tokyo Motor Show, and the S208 revealed last year. The 208 benefited from a bump in horsepower, from 323 hp to 329 hp and 319 pound-feet of torque, quick-ratio steering, a front strut tower brace, Bilstein dampers as part of a DampMatic II suspension, torque vectoring front and rear, 19-inch BBS wheels, Brembo brakes, a carbon roof, and an unmissable rear spoiler. None of the previous "S" models made it to the U.S. If this one does, we can only guess how Subaru will differentiate it from the hottest Impreza we've had, the recent Type RA (pictured). Our Type RA lost 68 pounds with the help of a carbon roof and spoiler, while a bag of engine mods and revised gearing helped make the most of unchanged 310 hp and 290 lb-ft from the 2.5-liter EJ25 engine. A power bump would likely be first on the wishlist for an S209, but it should be noted that the recent Japanese S cars have used the EJ207 2.0-liter boxer-four, not our 2.5-liter. As with the carmaker's home market, we'd expect an S209 to go into severely limited production. Subaru built 300 units of the S206, 400 of the S207, and 450 of the S208. Even if we do get a brawnier STI, Japan is likely to keep its power close with the WRX STI TC 380 teased last month, putting out 375 hp from a 2.0-liter turbocharged boxer-four. Still, the South-Africa-only WRX STI Diamond Edition rocked 349 hp and 342 lb-ft from its 2.5-liter, so there's a lot of headroom for a U.S. S209 to play with. If we get one, that is. Related Video:

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.
