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.

2021 Subaru WRX STI to pack 400 horsepower?

The next-generation Subaru WRX STI may boast as much as 400 horsepower from a re-tuned, 2.4L turbocharged boxer engine, making it the most powerful factory STI ever to be offered in America.  Forbes reports that an upgraded version of the engine currently offered in the three-row Subaru Ascent crossover will power the new model, rather than the 2.0-liter unit that powers the current WRX or the 2.5L found in the current STI.   According to the report, which cites an unnamed source close to Subaru, the company's engineers are hard at work beefing up the FA24 turbocharged boxer to coax 400 horses and 361 pound-feet of torque from an engine that currently offers just 260 horsepower and 277 lb-ft of torque in family-hauling tune.  While Subaru has been building high-output WRX and STI models for its home market for decades, this would be the first time a 400-horsepower STI would be offered for sale in the U.S. In fact, it would become the most powerful Subaru sold here, period. That honor currently belongs to the 341-horsepower 2019 STI S209, which is incredibly rare (and correspondingly expensive). It followed closely on the heels of the STI Type RA, which was similarly difficult to obtain, but not nearly as powerful or expensive.  Limited (as its name suggests) to just 209 units, the S209 was offered for only one model year at an eye-watering MSRP of $64,880. Customers are still taking delivery of their cars, as STI's tuning shop can only crank out a small handful per day. If it seems like Subaru has been taking its sweet time introducing a new WRX and STI, that's because development of the hotter models diverged from that of the base Impreza prior to the launch of the latter's latest generation. Subaru considers them independent models, and while they still share platform commonalities, they are no longer treated as a single product line. Current models are still loosely based on the last-generation Impreza, and the best hint we have as to the future of the WRX and STI is the Viziv Performance STI concept, which debuted at the Tokyo Auto Salon back in 2018.

Subaru WRX hatchback back off the table

It's fair to see we're rather fond of the new Subaru WRX. That's not to say we don't have a number of issues with the budget sports sedan, though. Foremost among those complaints is that it's short exactly one door. Yes, the sedan-only WRX is just fine, but we'd be lying if we said we weren't missing the long-roofed, five-door model of years past. More pressing than our sentimentality, though, is the business case for a WRX wagon - half of the 2013 WRX and STI models sold had five doors. As a general rule, ignoring half of your former customers isn't the best strategy for long-term success. There was some hope, as recently as a few weeks ago, though, that Subaru would right this wrong and offer a real, five-door WRX. An Australian reporter managed to corner project manager Masuo Takatsu, who said strong interest from the US meant that the Subaru mothership was considering a WRX with a hatch rather than a trunk. Sadly, that doesn't seem to be the case, as Subaru USA is dashing any and all hope of a second body style. According to Motor Trend, the company's US arm reached out to Japan and, despite the statements made by Takatsu, confirmed that there were no plans for a WRX wagon. Sigh...
