Upcoming Subaru WRX STI rumored to get hybrid drivetrain

Subaru might electrify the next-gen WRX STI. According to a rumor from Motoring in Australia citing an unnamed Subie insider, the brand's engineers reportedly have two hybrid systems under development for the future model. The move would allow the STI to boost power output and improve fuel economy and lower emissions to keep up with US regulations. According to Motoring's speculation, the next STI might use an electric motor at the back to power the rear axle and an upgraded version of the FA20 turbocharged 2.0-liter at the front. A new dual-clutch six-speed gearbox would help the power get to the road, and the total system could allegedly offer around 322 horsepower versus 305 hp from the current US model. This rumor also claims the next-gen STI would continue as a sedan when it arrives in 2017. Like previous iterations, the four-door will share underpinnings with the Impreza, which will mean a move to Subaru's new modular platform. The standard hybrid might only be the beginning of electrification for the future STI. Motoring's source also claims the company has a plug-in hybrid variant under development, but it might not debut until the 2018 Tokyo Motor Show. A hybrid STI could be exciting, but until there are solid facts, this rumor joins a long history of powertrain speculation about the high-performance Subaru. In 2008 and 2010, reports emerged about a diesel version, but it never appeared. We once even heard that the current-gen WRX might boast an electric turbo.

Toyota 86 most likely to get more power through more displacement? [w/poll]

The Sydney Morning Herald has spoken to Tetsuya Tada, chief engineer of the Toyota 86 (our version of it, the Scion FR-S, is pictured above), and they've been promised that more power is on the way. We've heard a lot of speculation about a more powerful Toyobaru since before the standard model was even launched. The only question now is how the power will be delivered, and among the engine concepts we've already heard about - turbo, supercharger, twin-charged, hybrid - is a new one: more displacement.
Tada said that an engine with more displacement than the current coupe's 2.0 liters is being tested alongside a turbocharged and a hybrid-assisted motor. The SMH cites "inside sources" as saying the displacement option is the one likely to get the go-ahead, and suggests increased bore and stroke will see the engine grow to 2.5 liters, horsepower to about 250 - a 50-hp increase over the present car.
While that's apparently the betting man's solution for the long-awaited increase in gumption, what happens with the next generation could be more wide open than we suspected. According to the report, Tada "hinted that [a successor] could be a radically different car, potentially dropping the boxer engine altogether." He said once they've sorted out the concept for the second generation car, then they'll sort out an engine. That's where a turbo option could come to market, perhaps the turbocharged four-cylinder Toyota is developing for the Lexus NX crossover or a hybrid system that uses a capacitor.

Subaru allegedly developing mid-engine hybrid sports coupe

A mid-engine, hybrid sports coupe could give Subaru a high-performance halo model in the coming years. According to Car and Driver, "a source close to Subaru" let slip the company has been testing the prototype powertrain underneath a BRZ at its proving grounds in Japan. "Whether the end result will be a two-door sports coupe or some kind of sports crossover/CUV is still in the evaluation stage," the anonymous source told Car and Driver. "A coupe seems more likely, though." The vehicle's layout allegedly uses a mid-mounted 1.6-liter turbocharged boxer engine with hybrid assist to spin the rear wheels, and two electric motors at the front would power that end. The resulting all-wheel drive powertrain would have about 330 horsepower or more, Car and Driver claims. If a production version happens, it would use the upcoming Subaru Global Platform. Rumors about Subaru's increased development of hybrids offer some support for this alleged sports coupe. The company reportedly might use electrification to boost the next-gen STI. In 2014, a story also suggested the automaker could revive the SVX as a performance-oriented hybrid shooting brake. More recently, even its Viziv GT Vision Gran Turismo concept combined a turbocharged boxer with three electric motors. While a Subaru sports coupe piques our interest, we are taking the prospect with a grain of salt for now. The Japanese brand has a tendency of teasing performance models but not actually delivering on them – like the STI Performance Concept (above) or the aggressive styling of the last WRX Concept. There could also be a long wait before we see what the company is developing. According to Car and Driver, a concept is at least two years away. Then it would take even more time for execs to okay production. Related Video:
