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 recalls 4,000 Tacoma pickups over valve springs

When you build as many cars and trucks as Toyota does, you're bound to run into the occasional recall. In the past month alone, the Japanese auto giant has recalled over 800,000 Camry, Avalon and Venza models over problems with the air-conditioning units, and 10,000 more before that over windshield wiper issues. Now Toyota has issued another recall notice, but this time for far fewer vehicles.
The recall revolves around the engine valve springs in the 2013 and 2014 Tacoma, specifically those fitted with the standard 2.7-liter four-cylinder engine and not the optional 4.0-liter V6. The issue is that the valve springs are prone to cracking and breaking over time, and results from improper maintenance of the manufacturing equipment used by one of the two suppliers that outfit Toyota with the components in question.
All told, some 4,000 vehicles will be subject to the voluntary recall, the owners of which will receive notice by mail. If you think that could be you and want to get a jump on the problem, you can read the announcement below and call Toyota yourself.
