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

Every time I drive a Subaru WRX, I wish one of my parents had taken some weird, top-secret spy job that would have forced us to relocate to Finland when I was a kid. I could have learned the art of rally-style car control as a young lad, and in my adult life, sought out a dangerous/rewarding/awesome career as a professional WRC driver.
Never was that more clear than on the launch program for the new 2015 WRX, where Subaru pointed us down a long, somewhat treacherous stretch of road in the tree-lined mountains of northern California. Quick elevation changes were met with blind turns and washed-out shoulders, not to mention rogue bits of snow, ice and gravel that lined the apexes of nearly every turn. Here, I couldn't stop grinning, my co-driver and I switching between second and third gears, with precise steering inputs and judicious braking keeping us safely on the road and not plummeting nose-first into the trees. And the WRX simply devoured each inch of pavement with a ferocious poise that made me remember why I have loved this car so darn much.
But this sort of 100 Acre Wood perfection isn't the only way to experience Subaru's darling WRX. After a long stint of driving back down the California coast on Highway 1, I realized that Subaru's line about this being the best-driving WRX yet wasn't just a bunch of PR mumbo-jumbo. Of course, it isn't without a few compromises...

2015 Subaru WRX STI goes for the gold [w/video]

If the all-new 2015 Subaru WRX has taken a good thing and made it great, then this should be, well, greater. Meet the range-topping WRX STI, packing more power, a decidedly more aggressive suspension tune, beefier looks, a giant wing and (woo!) gold wheels.
Those spiffy BBS wheels and WRC rally-ready matching WR Blue paint won't necessarily be around forever, though - Subaru is offering this package (along with unique interior trim) on the STI Launch Edition, limited to just 1,000 units. And cool as it may look, there's far more to love about the new STI package.
Power comes from a 2.5-liter turbocharged boxer four-cylinder engine, sending 305 horsepower and 290 pound-feet of torque to all four wheels via a six-speed manual transmission. (Launch Edition models even get a short-throw shift kit, which will likely be available as a dealer-installed accessory thereafter). Unlike the standard WRX, a do-it-yourself 'box will be the only transmission available. Subaru is employing its new - *ahem* - Multi-Mode Driver Controlled Center Differential version of the Symmetrical All-Wheel Drive, which, in addition to a standard 41/59 torque split, uses things like torque vectoring, and, when put in manual mode, allows the driver to select one of six center differential locking levels. In other words, the STI should be incredibly sharp on the road - sharper than ever before.
