Subaru launches STI-tuned Forester tS in Japan

Subaru Tecnica International, better known by its initials, STI, has finally unveiled its work at tuning the Forester into a higher performance machine. Unfortunately while tweaks to the suspension and styling are plentiful, it's not clear how much acceleration is going to improve from just a few minor upgrades to the powertrain. All of the tS models come with a turbocharged, 2.0-liter four-cylinder and continuously variable transmission. STI fits new software to control the engine and gearbox, plus a cooler for the CVT, but Subaru doesn't say what effect this has on overall performance. The Sport Sharp driving mode has also been also retuned in the SI-Drive system. However, the Forester tS should definitely be a better handler with a 0.6-inch (15-mm) drop for the suspension and STI parts for the strut tower brace and rear subframe support. The upgrade to forged 19-inch wheels from BBS and commensurately larger tires should help the CUV stick to the road better, too, and Brembo ventilated brake discs front and rear can bring things to a halt. On the outside, the Forester tS wears some subtle updates with a cherry-red pinstripe running around the front grille and rear bumper. STI also fits a new front and rear spoiler, plus black mirrors provide a little contrast on each side. Inside, there are some new seats up front with a mix of black leather and Ultrasuede with red stitching and matching door panels. We were hoping Subaru might let STI go wild on the Forester to create a higher-riding take on the WRX STI, but that didn't happen. The tS goes on sale in Japan on November 25 and is limited to just 300 units. Prices ring up at 4,027,778 yen before the country's consumption tax ($34,170). Scroll down for all the details about this hotted-up crossover. STI Releases Subaru "Forester tS" in Japan Nov 25,2014 Tokyo, November 25, 2014 - Subaru Tecnica International Inc. (STI)*1 today announced the release of the Subaru "Forester tS", which goes on sale on November 25 through Subaru dealerships in Japan. With a development concept focused on creating an on-road vehicle which has a rugged styling, responsive handling performance and quality feel, the Forester tS offers an enhanced version of the driving performance the Forester provides as an SUV, delivering the ultimate in driving enjoyment and pleasure of ownership. The Forester tS benefits from its own exclusive tuning the "S# (Sport Sharp) mode" for "SI-DRIVE".

Subaru WRX and STI meet at the dyno with interesting results

Road and Track recently put the 2015 Subaru WRX and the 2015 WRX STI through a battery of dyno tests to find out not only how much difference there is between their two engines, but what kind of differences there are. The WRX gets the company's new FA20 2.0-liter boxer four-cylinder engine with features like a twin-scroll turbocharger, direct injection and variable valve timing on its two cams. The WRX STI stands pat with the older EJ-Series motor, meaning a 2.5-liter boxer four-cylinder with port fuel injection and carryover turbo lag. Subaru pegs the $26,295 WRX at 268 horsepower, 258 pound-feet of torque and an "extremely conservative" 0-60 mile per hour time of 5.4 seconds. The $34,495 STI clocks in at 305 hp and 290 lb-ft with a 0-60 mph time of 5.1 seconds. Ok, fight.
R&T's dyno runs sussed power numbers at the wheel of 223 hp and 245 lb-ft for the WRX, 247 hp and 243 lb-ft for the STI, then went on to demonstrate in numbers what everyone knew: that the WRX consistently puts out more of its torque earlier than the STI and achieves full boost almost three seconds quicker. On the other hand, on the track, the STI was also shown to have a conservative official 0-60 mph time, stopping the timer at 4.8 seconds compared to the WRX's 5.2 seconds.
The mag says it has comprehensive results coming from its "complete battery of tests," but for now, you can scrutinize their dyno charts and let the battle continue about which one you'd rather put your money down for.

NHTSA investigating 33k Subaru Imprezas for airbag sensor flaw

The National Highway Traffic Safety Administration is beginning an investigation into an estimated 33,500 units of the 2012 Subaru Impreza because of a potential flaw with the sensor for the airbag system. The government agency has 26 complaints about possible faults with the Occupant Detection System for the front passenger seat, and this is the sensor that decides whether a person is an adult, petite, child seat or some other object and adjusts the deployment of the airbag accordingly. However, these reports allege that it was incorrectly turned off when someone was in the vehicle, which caused the airbag not to activate. Subaru put out a Technical Service Bulletin in May 2012 that attempted to address a similar problem. For now, this investigation is classified as a preliminary evaluation and is gathering more data about the potential problem to "assess the scope, frequency, and consequence," according to NHTSA.

SUMMARY: The Office of Defects Investigation has received 26 Vehicle Owner Questionnaire reports involving the passenger frontal air bag in MY 2012 Subaru Impreza vehicles. These vehicles use a capacitive type Occupant Detection System, which is intended to classify the occupant of the passenger seat as either full sized, small stature, a child seat or other object. The reports allege that the Occupant Detection System, failed to operate properly and incorrectly suppressed (turned off) the front passenger air bag when the seat was occupied. In a frontal crash sufficient to warranty deployment, a suppressed air bag may increase the risk of injury to the occupant of the seat. Additionally, ODI notes that Subaru published a Technical Service Bulletin (TSB) No. 17-16-12 on May 29, 2012 to address conditions with the Occupant Detection System that can lead to suppression of the passenger air bag when the passenger seat is occupied. ODI is opening this this investigation to assess the scope, frequency, and consequence of incorrect air bag suppression and any connection that may exists to the TSB.
