A closer look at the 2015 Subaru Legacy

The Subaru Legacy might not have been the hottest debut at the recent Chicago Auto Show, but for the Japanese automaker, it's hugely important. Much as we'd love to focus on Subaru's more engaging WRX, STI and BRZ models, the truth is, its the mainstream Forester, Outback and Legacy that make up the vast majority of the brand's sales, not to mention the Impreza and XV Crosstrek.
This new Legacy looks to gain a lot more traction in the mainstream market than its predecessor, with handsome, if familiar, styling, standard all-wheel drive, and more efficient powertrains. Under the hood, customers can choose between a 2.5-liter boxer-four, or a more powerful six-cylinder engine. Subaru says that the four-cylinder setup actually boasts class-leading fuel economy for all-wheel-drive vehicles in the Legacy's class.

Subaru investigation confirms vehicle data tampering in Japan

Subaru has admitted that alteration of fuel-economy and emissions data took place in its Gunma and Yajima manufacturing plants between December 2012 and November 2017. Some 900 vehicles were affected by data tampering, which Subaru says was done in the vehicles' final inspections by factory-floor inspectors. In a report, Subaru says "non-conforming" final vehicle inspections were identified in late 2017, and that the Japanese Ministry of Land, Infrastructure, Transport and Tourism demanded that Subaru undertake an internal investigation of the matter. Almost 7,000 vehicles were subject to inspection in the investigated time period, and the measurement equipment retained test data for some 6,500 of those. It showed that 903 vehicles had had their data "inappropriately altered," partially so that average data values would meet quality control standards. Subaru says that the decision to do this was made among vehicle inspectors and their foremen. As Subaru's statement reads: "Inspectors engaging in sampling of fuel economy and emissions were instructed by their seniors that, if results for each vehicle did not meet such standards, measurement values should be altered to those that meet such standards, and, according to such instructions, the inspectors altered measurement values. [...] Even if there were no problems in comparison with the internal quality control standards, inspectors altered measurement values with the intention of reducing variance in measurement values in order to avoid questions from the Group Chiefs and the Section Chief on such variance. It should be noted that alterations were made not only to make results better, but also to make them worse." It appears that everything was done to keep the average values right. Subaru adds: "Although the relevant laws and regulations stipulate that, in certain limited cases, measurement values could be altered in order to adjust errors caused by measurement equipment, inspectors misunderstand such adjustment method because of deficient internal rules and inadequate training. Inspectors altered measurement values by adjustment methods not stipulated in the relevant laws and regulations, without understanding that their methods were inappropriate." Test equipment did not contain data from earlier than 2012, but Subaru suspects such tampering took place as long ago as 2002. However, the matter will not result in recalls.

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.
