Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

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.

Choose the right tool | 2017 Subaru BRZ Performance Package Second Drive

There's something to be said for using the right tool for the job. It's not always possible, but you know that when you whip out the Vise Grips, deep down inside, it just feels wrong. There's satisfaction, joy, even dignity in using the proper instrument to execute a task accurately on the first try. Our attempt to wield the updated 2017 Subaru BRZ on Fuji Speedway last year were stymied by summer fog that rolled into the base of Mt. Fuji, reducing visibility to just a couple of car lengths. But it's an extremely fast circuit with a nearly mile-long front straight so even on a clear day, it's not the ideal venue for the BRZ. Which is why we accepted Subaru's invitation to take another go at it, this time at Circuito Guadix, an off-the-beaten-path track near Granada, Spain. (If you go, try the paella.) The Performance Package is the highest spec available on the chassis to date in the US, and that includes its Toyota and Scion brethren. The setup is exclusive to the BRZ line and has no Toyota counterpart. With a price of $1,195 on top of (and only available on) the $28,465 Limited trim level with a manual, it gets you a host of upgrades to its unsprung components, all of which would cost several times more if procured piecemeal in the aftermarket. Sorry, there are no power upgrades, save for the bump of five horsepower and five pound-feet of torque on manual-transmission 2017 models. The most noticeable of the enhancements are sharp, gunmetal-finish 17-by-7.5-inch wheels, inspired by the famed RS-Watanabe design that adorned Japanese touring racers of the 1970s. The extra half-inch of width accommodates larger Brembo brakes — four-piston calipers up front biting down on rotors that have grown by 0.95 inches in diameter and thickness to 12.8 by 1.18, and two-pot calipers pinching 12.4-by-0.79-inch rotors, up from 11.4 by 0.71, out back. These are the same brake dimensions as you'll find on the car Subaru still considers the flagbearer of its enthusiast lineup, the rally-ready WRX STI. Performance Pack BRZs are suspended by Sachs ZF dampers and incur a weight penalty of just 20 pounds over the Limited. The Series.Yellow seen here takes all the goodies of the Performance Package and adds exclusive yellow paint that Subaru is quick to point out is entirely different from the yellow that appeared on the 2015 Scion FR-S Release Series 1.0. We'll concede that it's less boy-racer, but only slightly.
