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 to get CVT option?

The 2015 Subaru WRX will make its debut at the 2013 Los Angeles Auto Show next week - that much we know for sure. We'll have all of the official specs very soon, but it seems Jalopnik has stumbled upon an official-looking document that spells out some of the 'Rex's finer details, including the availability of a continuously variable transmission.
Now, before you throw your laptops and phones out the window, know this: a proper manual transmission will still be available. Do remember, the WRX has always had an automatic option, and the move to a CVT for the 2015 model isn't terribly surprising. According to the document, the new WRX will use a 2.0-liter turbocharged flat-four - a change from the 2.5-liter engine in the current car. Subaru also employs a 2.0T boxer engine in the Forester, where it's mated to a CVT. What's more, the Impreza on which the new WRX is based also uses a CVT in favor of a conventional automatic.
Jalopnik points out that the more hardcore WRX STI will use a 2.5-liter turbo-four, and will only be available with a manual transmission. Additionally, there will reportedly be a "launch edition" of the STI, painted in the car's signature WR Blue (fingers crossed for gold wheels!).

Subaru's first hybrid drawing close

In 2011 Subaru parent company Fuji Heavy Industries confirmed that a hybrid Subaru would debut this year. Ever since, there's been speculation about what kind of technology the gasoline-electric hybrid would use - Subaru's own or some version of the Toyota Hybrid Synergy Drive, which car would debut the new system - Forester, Legacy, or Outback - and whether it would come to America or be a Japan-only model.
A report in The Detroit Bureau says that whatever that first model is, it could be shown as soon as the New York Auto Show, and while the company feels it's a must-have offering for the Japanese market it will also come to the US. It will have a Subaru-developed mild hybrid system that could have been previewed by the Hybrid Tourer concept shown at the 2009 Tokyo Motor Show, and is not expected to be able to drive on electric power alone. The Hybrid Tourer used a direct-injected, 2.0-liter boxer engine connected to a CVT and assisted by an electric motor rated at 13 horsepower. Subaru has yet to give anything away about the details of its hybrid plans, so we'll look to New York for the long-awaited unveil.
