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.

Watch Mark Higgins whomp the Isle of Man TT course in a 2015 WRX STI

Subaru has made another trip to the infamous Isle of Man TT, bringing along its all-new 2015 Subaru WRX STI. The goal? Best the already impressive time set by rally ace Mark Higgins and the 2011 Impreza WRX STI on the same swirling, high-paced ribbon of tarmac. Of course, you already know how that went.
What we didn't know when the story first broke, though, was that Subaru was monitoring data. Specifically, Higgins' data. He was fitted with a monitor that would record his heart rate, breaths, skin temperature and the g forces he was faced with as he lapped the 37-plus-mile road course. While Higgins and Co. were aiming to best their 2011 time (19:56.7), this year's effort also saw a push to beat the time of the sidecar racers.
You can get a recap of the entire event, with plenty of footage and data from Higgins' lap in the exhilarating video below. Take a look.

Subaru WRX hatchback mule spotted

Despite on-again, off-again rumors, this latest set of spy shots seems to indicate that yes, a five-door Subaru WRX is indeed in the works. Subtlety is key with this test mule, but there are clear bits of evidence that indicate a hotter hatchback is what's being developed here.
First, notice the WRX-spec front fascia grafted onto this ordinary-looking Impreza hatch. From there, we can clearly see the tiny bit of added width - most obvious on the roof and at the rear, near the fuel door and taillamps. And of course, let's not forget about that bulge in the hood, consisting of a metal panel that covers the hood scoop and can apparently be removed thanks to a series of screws, according to our spies. The WRX's more robust exhaust and larger wheel/tire package have not been added to this mule, though we're told that this is commonplace for Subaru prototypes - those bits should be added on as the car's development progresses.
We fully expect a WRX hatchback to be, well, just that - mechanically, it should be identical to the sedan brethren, though our spies indicate that Subaru could be testing an updated version of the WRX-spec boxer engine. Of course, there's always a chance that this could be something else entirely, given the on-and-off reports of the five-door 'Rex's existence in the first place...
