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.

2017 Scion FR-S getting slight power bump?

A common refrain when discussing the Scion FR-S and its sibling the Subaru BRZ is that they are capable vehicles but are in need of more power. The latest rumors suggest that some more muscle might finally be on the way for the coupe's refresh. Don't expect something like the STI Performance Concept with a 300-horsepower, turbocharged flat-four, though – the gains in the real world are likely to be significantly more modest. According to Toyota insiders speaking with Motoring in Australia, the local Toyota GT86 (our FR-S) is due for a styling and powertrain refresh for the next model year. The 2.0-liter boxer four-cylinder engine isn't expected to get a drastic power increase, but it's not being completely neglected. A new intake manifold and friction reductions reportedly allow for five percent more grunt. If accurate, and if the changes also come here, that would take output of the US version to 210 hp and 159 pound-feet of torque. The adjustments could improve fuel economy by seven percent, as well. Handling is already a forte for the FR-S and BRZ, and things could get even better with this refresh. Motoring claims that dampers from Sachs might become standard equipment, along with a reinforced subframe. The close relationship with the BRZ reportedly rules out any dramatic changes to the styling for this update. However, the coupe is still likely to wear a new hood with vents in it, reshaped headlights, and a revised fascia with a larger lower grille. At the rear, expect a rear diffuser and exhaust pipes at the corners. While minor compared to all of these rumored updates, Scion recently gave the FR-S a few tweaks in the US for the 2016 model year (pictured above). In addition to some new colors and interior trim, it now comes standard with a seven-inch touchscreen infotainment system and rearview camera.
