Subaru updates EyeSight system with color-detecting cameras

Subaru is giving its EyeSight driver assistance camera system a major upgrade for the 2015 model year with new color cameras, as well as reducing its size by 15 percent over the rather bulky original system.
Subaru locates its EyeSight hardware inside the vehicle at the top of the windshield, which is unlike most other camera-based systems that have their hardware mounted somewhere in the front fascia. The benefit is that these rather expensive components are protected from any detritus that may hit the car, but the original system's size ate up a chunk of the driver's outward view. Thus, the shrinkage should be appreciated by new owners.
The upgraded stereo cameras have a 40-percent longer and wider detection range than the original system's cameras, and their ability to see color allows the system to recognize brake lights at a speed differential of 30 miles per hour, instead of 19 mph before. And as before, EyeSight continues to offer adaptive cruise control, lane departure warning and pre-collision breaking that can slow the car automatically if an imminent accident is detected, even bringing the vehicle to a complete stop.

Subaru STI Performance Concept previews a bright BRZ future [w/video]

Subaru unveiled its STI Performance Concept car today at the New York Auto Show, a BRZ-based corner carver that says as much about the future of STI in America as it does about the future of the BRZ. And while this marks the world's first official look at the STI concept, Subaru gave me a preview of the car, and a long description of its significance, on a trip to Japan last month. The Performance Concept sends a tangible message about the motorsports heritage and engineering capability of Subaru Tecnica International. STI started life as the motorsports arm of Subaru parent Fuji Heavy Industries. Appropriately, the concept car uses a racing powerplant. Under the hood is the same turbocharged, 2.0-liter boxer-four that powers the BRZ GT300 from Japan's Super GT series, estimated at around 300 horsepower and 330 pound-feet of torque. But the STI concept is more like the ultimate road version of the BRZ instead of a recapitulation of an existing racecar. Chassis, suspension and braking components can all be found on the Japanese Domestic Market's road-going BRZ tS, for instance. Subaru invited me to drive the tS on that same trip, so stay tuned for a report on that experience later this week. It will pain Subaru fans to hear that this concept is not a defacto preview of a forthcoming turbocharged BRZ STI, at least not in the immediate future. STI has been charged with expanding its presence and reach in the North American market, but the process is going to roll out slowly without jumping straight to a fully realized production vehicle. Stage one of the STI expansion will be a consolidation of parts and aftermarket support in the US. Subaru has offered a pastiche of performance products through its dealerships up to today, including the US-only Subaru Performance Tuning (SPT) parts. In the near term, the company will phase out SPT in favor of STI parts and accessories, meaning you'll be able to purchase a lot of the stuff that the Japanese market has today. And we're talking about parts that actually impact performance, not just STI-badged shift-lever knobs or gas caps. The STI Performance Concept does show that Subaru sees a future for its rear-drive coupe in the American market, and that it wants to cater to enthusiasts. Stage two, which will happen in roughly the next year and a half, is to bring an STI-tuned version of the BRZ to the US, not unlike the JDM BRZ tS.

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.
