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.

Hi-po Toyota GT86 to get KERS?

We happen to like the Toyota GT86 - and, it of course goes without saying that the same applies to the Subaru BRZ and Scion FR-S, as well - just the way it is. Yes, that includes the standard 2.0-liter four-cylinder boxer engine and its 200 horsepower at 7,000 rpm.
That said, a little extra power never hurt anybody, right?
The most obvious way to add some punch to the GT86 would be with a turbocharger, and that has indeed long been rumored for an STI version of the BRZ. Will Toyota follow suit? According to Top Gear, the answer is no. Says GT86 chief engineer Tetsuya Tada, "I think 300bhp with a turbo and 200g/km of CO2 would be tasteless in this day and age. And a turbo would mean the loss of the GT86's uniqueness." Perhaps a bit harsh, but there you go.

Subaru teases Impreza sedan concept for LA

When the doors open at the Los Angeles Auto Show later this month, Subaru will be on hand to preview its upcoming Impreza. But before it does, it's giving us an idea of what to expect. Although we can only see so much of it from the teaser image above, the Impreza Sedan Concept pictured here for the first time looks similar to the Impreza 5-Door Concept we saw in Tokyo mere days ago. It seems to bear the same headlights and the same sculpted flank as the hatchback show car. Only as you might have discerned by now, it has a trunk instead of a tailgate. And instead of that blueish-silver, this one's done up in metallic red. For more than that, we'll have to wait. And it's entirely possible that even when it does arrive, Subaru won't tell us much about the technical specifications. Many of these concepts don't actually have engines, after all, When the new Impreza does reach production, it will in all likelihood feature a boxer four engine and all-wheel drive. Subaru to Debut "Impreza Sedan Concept" at 2015 Los Angeles Auto Show Tokyo, November 10, 2015 – Fuji Heavy Industries Ltd.
