Subaru Viziv Performance STI Concept has us dreaming of a future WRX STI

Subaru has revealed the Viziv Performance STI Concept at the Tokyo Auto Salon, and it's pretty much what you would expect. It's very closely related to the Viziv Performance Concept from the Tokyo Auto Show last year, but it's been given a bevy of flashy STI parts to make it aggressive. Up front, a deep lip spoiler complements a redesigned front bumper that does away with the two outboard air intakes and opens up the center one. According to a Subaru designer, it improves the cooling and aerodynamics. Having the blocked-off intakes on each side with STI logos is also a nice throwback to old Impreza STI models that often had blank panels with the logo over the foglight openings. Around the side are side skirts, and at the back are small extensions to the same diffuser from the earlier Viziv concept. And of course, there's a massive wing at the back. What's interesting is how much of the normal Viziv remains under the STI logos, decals and wings. The fenders look nearly untouched, and the hood scoop is the same size and shape as the standard concept. Even the exhaust, taillights and headlights are all the same. Then again, between the production WRX and WRX STI, the only real visible differences are the rear wing, wheels and front spoiler. And, if the Viziv Performance concepts preview future WRX and STI models, following that model makes sense. Of course the big differences between WRX and STI models are under the skin. Unfortunately, Subaru doesn't reveal a thing about what hypothetical powertrain is under this STI. Maybe we shouldn't be so surprised though, since the company didn't say anything about the regular one either. Only the use of a flat-four and all-wheel drive are certain. For that matter, even the styling isn't truly certain. While we can hope that the next WRX and WRX STI have the muscular look of these concepts, we have reason to be skeptical. But instead of getting cynical and sad, let's just enjoy this for what it is: a cool STI concept. Related Video:

Subaru could have all-electric CUV by 2021

Subaru doesn't exactly have an industry-leading electric vehicle program. It sells the Impreza Sport Hybrid in Japan and the Crosstrek Hybrid in the US. There have been electrified rumors and concept cars, but Subaru has been more content to promote getting out into the environment rather than using your car to help it. But maybe this'll change in 2021. That's when, according to a report in the Nikkan Kogyo Shimbun newspaper in Japan, the automaker will introduce an midsize, all-electric AWD CUV in the US. The EV would be based on the Forester or Outback and use a new global platform. As for where the cells, batteries, or motors would come from, there was no mention. The newspaper cited unnamed sources and all that an on-the-record spokesperson would say is that, "We have yet to decide on any specifics at the moment." Or, as Subaru of America's national manager of product communications, Dominick Infante, told AutoblogGreen, "It's a bit early for us to discuss electric vehicles and PHEVs." There's a good reason for Subaru to be considering going electric, and it's the same one that's pushing the entire industry to zero-emission vehicles: tighter emissions regulations. As much as we want to know everything now, it appears that Subaru is taking the same approach to all-electric vehicles as it did with hybrids. At the New York Auto Show in 2013, Subaru's executive vice president Tom Doll said that, "We at Subaru were not the first to market with a hybrid, but we sure made sure we did it right." If it takes the company until 2021 to release an EV, it had better get it right. Related Video:

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.
