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 unveils catchily named WRX STI tS Type RA in Japan

We feel safe in saying it's time for Subaru to step away from the keyboard for a spell. The company just unveiled this new WRX STI tS Type RA in Japan, and while the car features all sorts of tricks to help it stand out from the rest of the WRX rabble, it also boasts a name that looks like the product of a good old fashioned QWERTY Hulk smash. Nomenclature aside, this WRX STI features a revised suspension with tweaked springs and dampers as well as a faster steering ratio, Brembo brakes and a front strut tower brace.
JDM buyers can pick between the ever-sexy (if loud) Tangerine Orange Pearl paint seen here, Satin White Pearl or Blue Mica. There's also available NBR Challenge Package, complete with a set of Recaro front seats, a few carbon fiber aero bits and 18-inch BBS forged wheels wrapped in Bridgestone Potenza RE070 rubber. How's that for delicious?
Subaru is only planning to crank out 300 WRX STI tS Type RA units, two-thirds of which will carry the NBR goodies.

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.
