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.

2015 Subaru WRX looks to set a new benchmark in LA

Subaru has just taken the wraps off of the new, 2015 WRX at the 2013 Los Angeles Auto Show. The totally redesigned sedan - the five-door option won't be offered - is more powerful, more fuel efficient (with the right transmission), better looking and more intelligently designed than the car it's replacing.
A new 2.0-liter, direct-injected, turbocharged flat-four sits thumping away under the hood, its top-mount intercooler getting force-fed air by a rather prominent hood scoop. Power output sits at 268 ponies and 258 pound-feet of torque, accessible between 2,000 and 5,000 rpm. While the new car only has a three-horsepower advantage on the current Impreza WRX, it delivers 14 more pound-feet of torque and delivers peak output across a much wider swath of the rev range (the old car netted 244 lb-ft at 4,400 rpm). All this extra grunt comes at a negligible weight penalty - a 2015 WRX with the six-speed manual is just 59 pounds heavier than a 2014 model.
As we said, a six-speed manual is will be available, and as a bonus, it packs one additional cog over the current, 2014 WRX's five-speed DIY transmission. So equipped, the WRX will scamper to 60 in just 5.4 seconds. As for the previously-confirmed continuously variable transmission, it will come with both six- and eight-speed manual shift modes, but will take half a second longer to get to the magical 60-mile-per-hour mark.

Subaru teasing new WRX S4 model ahead of Japanese debut

The Subaru WRX range is growing just a little bit larger, at least in Japan, with the automaker's teasing announcement of a new version called the S4. Unfortunately, the company is keeping details about its latest all-wheel drive sport sedan a closely guarded secret for the moment.
From what we can glean, it appears that the S4 might be a more luxurious take on the WRX. According to the release, the name stands for the four qualities that Subaru wants the sedan to have: "'Sports performance', 'Safety performance', 'Smart driving' and 'Sophisticated feel.'" As part of this focus, the car comes with the company's EyeSight camera system. Thankfully, we don't have too long to wait to find out what all of the buzz words actually mean because Subaru is unveiling the S4 on August 25 in Japan.
The automaker also launched a teaser website for the S4 that you can cheek out, here, but at the moment it doesn't provide any more details about the new sport sedan. The site just has countdown until the August reveal. There's also no indication yet whether this potentially more premium WRX could make it US shores. Scroll down to read the Subaru's rather concise teaser for the upcoming S4.
