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.

Subaru uses a mime and a toy car to explain why it loves the boxer engine

I will freely admit to struggling with why Subaru continues to stubbornly employ a boxer engine design while so few other automakers do the same. After all, with twice the number of cylinder heads and cams as a traditional inline four-cylinder engine, a boxer four is more complex, more expensive to manufacture and more cumbersome to service with few tangible benefits. Until recently, the company's engines struggled to meet the fuel economy numbers of its competitors while offering no real boon in horsepower or torque. Subaru seems to recognize I'm not the only one scratching my head.
In order to help us non-believers understand what's what, the company has employed a pair of mimes, a toy car and a few clay engines to demonstrate the folly of every other automaker on the planet. Subaru says the boxer offers up a lower center of gravity than either an inline four-cylinder engine or a V6, which I will gladly concede. The company also says the design offers up smoother operation.
I'll offer just two counterpoints here. First, an engine with a low center of gravity is excellent, but when vehicles like the Forester, XV Crosstrek and Outback boast more ground clearance than most mainstream SUVs, that argument flies out the window. Second, anyone who's spent any amount of time behind the wheel of a vehicle equipped with an inline four and then proceeded to move into one propelled by a boxer can tell you the latter has all of the idling manners of a small tractor.

BTW: Subaru's SHARC won the 2012 Design Challenge

Part of the festivities that encompass the LA Auto Show is the annual LA Design Challenge. This year's winner was the Subaru Highway Automated Response Concept, or SHARC. It envisioned automated, zero-emission highway patrolling.
The 2012 edition of the challenge was to envision the future of highway patrol in the year 2025. The goal was to conceptualize a vehicle that would account for the needs of "dynamic urban environments." In addition to Subaru's participation in the contest BMW, General Motors, Honda and Mercedes-Benz, all took part in the challenge.
The SHARC is essentially a law enforcement land-drone. It is entirely automated and runs on renewable energy. Subaru envisioned a future where the Hawaiian Islands are connected to each other by a large highway system. Such an expansive area would require considerable manpower to patrol. The concept of an autonomous patrol vehicle would eliminate the need for a good number of full-time personnel.
