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.

Toyota CamRally is vanilla spiced

We weren't quite sure it was possible, but NASCAR driver Parker Kligerman and the other folks behind this Toyota Dream Build Challenge vehicle (check out the other cars in the challenge) have made the Camry, a versatile but vanilla family sedan, into a performance car to be reckoned with. And by stripping it (literally) of its versatility and injecting some spice into it, this rally-spec Camry does indeed appeal to the enthusiast crowd.
The appeal starts with the CamRally's vintage Toyota racing colors of red, orange and yellow painted on a widened body. Those wide fender flares and rocker panels, paired with the revised front and rear fascias (and massive rear spoiler), lend the car an aggressive look without being tacky, and enhance the aerodynamics. But peel back the skin and you'll find plenty of performance upgrades to back up the looks.
While Toyota doesn't say how much horsepower it makes, the CamRally's V6 is turbocharged, and we assume the car's brake upgrade is indicative of the engine's increased output. The stripped interior only contains what's needed for rally racing, including bucket seats, a motorsport steering wheel covered in Alcantara, a carbon-fiber dashboard and a roll cage.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
