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 Legacy revealed with sublime interior, new platform

The completely redesigned 2020 Subaru Legacy just took the stage at the Chicago Auto Show, and it looks like a ... Subaru Legacy! We tease, because while Subaru has ever so subtly changed the metalwork everywhere you look, it's not obvious at first glance. Creases turn in slightly different directions, the fenders pop out just a bit more, and the wheels are different. To really see the difference, you should look at the cabin, underpinnings and mechanicals, where Subaru gave the seventh-generation Legacy a thorough overhaul. Subaru hasn't changed the Legacy's identity, but we're glad to report that this "all-new" Legacy represents a significant step forward for the model. The midsize sedan hops onto the Subaru Global Platform introduced a couple years ago with the Impreza. This structure is much more rigid than the 2019 model year car's platform, and also increases the use of ultra-high-tensile steel and structural adhesives. All this basically means that the new Legacy is stiffer, lighter and safer than the outgoing model — all good qualities to inherit. Both engine options are reasonably attractive for 2020. Subaru is ditching the 3.6-liter flat-six as the premium option and moving to its new 2.4-liter turbocharged boxer-four introduced in the Ascent SUV. It makes the same 260 horsepower and 277 pound-feet of torque here, good for 0-60 mph times of 6.1 seconds. Most buyers will end up with the standard 2.5-liter four-cylinder boxer, outputting 182 horsepower and 176 pound-feet of torque (0-60 mph in 8.4 seconds). This engine is also relatively new, as we got our first shot at it behind the wheel of the 2019 Forester. Both engines are predictably paired with Subaru's CVT. Your best fuel economy is achieved with the naturally aspirated four, rated at 27/35 mpg city/highway. You'll take a small hit with the turbo at 24/32 mpg city/highway. As the Legacy is still a Subaru, every version is equipped with all-wheel drive. A revised suspension design features a MacPherson strut setup in front and double-wishbone layout in rear. Subaru claims much higher dynamic performance and ride comfort with this suspension in combination with the new structure. We'll be the judge of that once we get behind the wheel, eventually. The interior is, in a word, impressive. We saw some hints of what Subaru is capable of with the Ascent's interior materials and design, but the highest-trim Legacy takes it to another level.
