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.

Toyota again claims Corolla outsold Focus worldwide

Toyota isn't convinced the Ford Focus was the best-selling nameplate globally last year. Bloomberg reports that for the second time in seven months, both Toyota and Ford are laying claim to the title. Ford cites R.L. Polk & Co. data that says the automaker moved some 1.02 million Focus models in 2012 compared to just 872,774 Toyota Corolla units. But Toyota says the actual figure is closer to 1.16 million Corolla models.
Last year, Ford said it took the sales crown through the fist half of 2012 based on information from IHS Automotive, but Toyota pointed out those numbers left out models like the Corolla-based Matrix and Auris, as well as the Corolla Fielder and Scion xB-based Corolla Rumion. Whether or not Toyota's belief that all these cars should be counted in the Corolla bucket is accurate or not is seemingly up for debate... as is the question of why it matters so much to both parties.
This time around, Ford is holding the line that the Focus is the "best-selling nameplate," with Erich Merkle, a US sales analyst with Ford saying the company's figure is, "a pure number that is verified by a third party." Toyota, meanwhile, has requested clarification from Polk.

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.
