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.

Subaru Viziv GT gears up for Vision Gran Turismo action [w/video]

Ever wonder what it would look like if Subaru made a big brother to the BRZ, maybe to take on the Nissan GT-R or Japan's Super GT series? (Well, the BRZ already competes in the GT300 class, but we're talking about the GT500 major leagues here.) Wonder no more, car fans, because it'd probably look something like this. Only it's not a road car, and it's not a racecar. It's the latest addition to the growing roster of Vision Gran Turismo concepts for GT6.
Borrowing on the design theme put forth by the Viziv concept that debuted at the 2013 Geneva Motor Show and the Viziv 2 concept showcased the following year, the Viziv GT Vision Gran Turismo is envisioned as a racing machine. Its hypothetical hybrid powertrain pairs a 2.0-liter boxer four, turbocharged and direct-injected, to a trio of high-output electric motors to deliver a claimed 591 horsepower and 593 pound-feet of torque.
Carbon fiber construction helps offset the weight of the motors and batteries to keep the hybrid racing shooting brake down to a theoretical 3,000 pounds, with competition-spec aero to keep it glued to the track. Gamers will be able to download it directly in the game as part of the latest update, but you can scope it out right here in the image gallery above and the video and press release below.

This Subaru BRZ has a snowmobile engine and gets 104 mpg

A hybrid powertrain didn't win the Honda CR-Z numerous fans, but it might be the magic ingredient in making the Subaru BRZ more potent. This is the "Car of the Future" as envisioned by Mississippi State University's Center of Advanced Vehicular Systems – the result of a two-year project, which married a front-mounted 850 cc snowmobile engine with two electric motors powering the rear wheels. The battery pack accounts for 12.7 kWh, which enables the car to go 50 miles on just electric juice. The two-liter boxer engine is no more, but what the car loses in cubic inches it gains in MPG. According to MSU engineers, the re-engineered car gets 104 mpg equivalent, and it only weighs 2,904 lbs: about 60 lbs more than an unmodified Sportshift BRZ. It clocks a 0-60 mph run at around 5.7 seconds, too, which beats a stock automatic BRZ by a second. The electric brain of the car improves the range by calculating optimizing algorithms, based on earlier driving. The guys from MSU's Bagley College of Engineering call this Predictive Engine Control. The most likable thing about this project might be that it's still clothed in a sports car body. Future-proof car designs are often focused on mobility instead of the driver, and choosing a BRZ as the basis shows how there's still room for petrolheads in the future.
