Subaru Legacy Concept has us getting our hopes up

It happens all the time. We get excited about a really attractive Subaru concept, and then the production car comes out and, well, "disappointed" isn't a strong enough word. (Compare that hot Impreza concept to the final production car.) So while we're hopeful that this new Legacy concept previews something sleek for Subaru, allow us to be fully on record as not getting our hopes up.
Anyway, let's talk about how good this car looks. From the front, comparisons to the Buick Regal GS are warranted, but from all other angles, it has a very four-door coupe-like shape. The concept rides on 21-inch wheels with bulging wheel arches that Subaru says hints at the car's all-wheel-drive system (standard Subaru fare, BRZ aside).
As for what exactly this concept previews, the safe guess is, of course, the next-generation Legacy midsize sedan. And while we'll keep our fingers crossed for a sweet-looking production sedan to come out of Fuji Heavy in the near future, it's safe to say we're still skeptical.

Subaru WRX Concept hints at big performance, offers few facts

We're looking at a design statement only at this point.
Subaru has dropped the curtain on its truly attractive WRX Concept and, as previewed a few days ago, we're fast fans of the wide, low, muscular sedan. The concept car looks great, but there was a distinct lack of information being offered about the next-generation WRX that is sure to follow this concept - we're looking at a design statement only at this point.

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.
