Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

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 Yaris Hybrid-R is road-going version of brand's racing technology [w/video]

Did you know that the Yaris is Toyota's best-selling vehicle in Europe? That may help explain to us Americans why the car that's lowest on the company's totem poll here in the US got turned into an all-wheel-drive hybrid track monster for the 2013 Frankfurt Monster Show.
Called the Toyota Yaris Hybrid-R, this three-door pocket rocket isn't just a hybrid making a lot of horsepower - it incorporates technology from Toyota's TS030 Hybrid racecar that competes in the FIA World Endurance Championship series, including the 24 Hours of Le Mans. The Yaris Hybrid-R packs a 300-horsepower, turbocharged, 1.6-liter four-cylinder engine under its hood, which should be enough for most speed freaks, but Toyota pairs it with two 60-hp electric motors at each rear wheel (the same ones used in the production Yaris Hybrid that's sold in Europe). That makes total system output an insane-for-this-size 420 hybrid horsies.
But that's not all, as the Yaris Hybrid-R forgoes the traditional battery pack below the rear seats in favor of a supercapacitor, which can both hold more energy and has a much faster power charge/discharge speed than traditional batteries. Paired with the supercapacitor is a third 60-hp electric motor/generator positioned between the engine and six-speed sequential transmission. Its job is to feed the super capacitor energy during deceleration and direct its power to the rear electric motors when more grip and oomph is needed.
