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.

Autoblog Minute: VW finds CO2 'irregularities', Takata dropped by automakers, SEMA recap

Volkswagen's diesel emissions scandal gets a new wrinkle, US regulators hit Takata Corporation with a substantial fine, and we head to Las Vegas for a look at tuner paradise at the 2015 SEMA show. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Volkswagen's diesel emissions scandal gets a new wrinkle. US regulators issue a significant fine to Takata Corporation. And we take a peek inside tuner paradise at the 2015 SEMA show. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. The VW diesel emissions scandal, first brought to light in September, gets a new wrinkle, as an internal investigation by the German automaker revealed [00:00:30] irregularities in CO2 emissions that could affect approximately 800,000 vehicles. VW estimates the issue could pose a 2-billion euro economic risk. VW claims that most of the vehicles affected have diesel engines, but industry analysts say a 1.4-liter gas engine is also affected. VW says that fuel consumption figures were set too low during the CO2 certification process. During all of this, sales of some diesel-powered Volkswagen, Audi, and Porsche models [00:01:00] have been halted. Takata Corporation is back in the news in connection with its deadly airbag scandal. Federal regulators fined Takata $70 million. If the parts supplier does not comply, the fine could balloon to $200 million. Takata was also dropped this week by its biggest customer, Honda. And now, Toyota and Mazda will be following Honda's lead in dropping Takata. We're also hearing that Mitsubishi and Subaru are considering a switch in air-bag inflator suppliers. SEMA 2015 [00:01:30] came and went. We saw offerings from Mopar, like the AWD Challenger concept. Honda unveiled a Ridgeline that it will race at the Baja 1000, which gives us a hint at what future production model could look like. The celebrity presence was also felt in Vegas as it always is. Kid Rock brought a Duramax Diesel Chevy Silverado, and Acura restored and presented Ludacris with his now famous 1993 Acura Legend. Those are the highlights from the week that was. Be sure to come back on Saturday for my full recap, [00:02:00] where I'll have some added insight into Hyundai's foray into the luxury sector. For Autoblog, I'm Greg Migliore.

Suppliers love Toyota and Honda: Why that matters to you

You might think that a survey of automotive suppliers and their relationship with OEMs is the automotive equivalent of nerd prom. In some ways that's what the North American Automotive OEM-Supplier Working Relations Index (WRI) is. The study, the 17th annual conducted by Planning Perspectives Inc., is based on input from 652 salespeople from 108 Tier One suppliers, or, PPI points out, 40 of the top 50 automotive suppliers in North America. Suppliers to General Motors, Ford, FCA, Toyota, Honda, and Nissan. But the results have consequences in terms of tens of millions of dollars for OEMs - and in the quality, technology, and cost of the next vehicle you buy. There are a couple of ways to look at the results of the WRI. One is, "So what else is new?" And the other is, "Damn! How did that happen?" The study looks at five relationship areas — OEM Supplier Relationship; OEM Communication; OEM Help; OEM Hindrance; Supplier Profit Opportunity — within six purchasing areas — Body-in-White; Chassis; Electrical/Electronics; Exterior; Interior; Powertrain. In the overall rankings, Toyota is on top for the 15 th time in 17 years, with a score of 328. Honda, the only company to best Toyota (in 2009 and 2010), comes in second, at 319. Those two companies, explains John Henke, president of PPI, have collaborative working arrangements with colleagues and suppliers alike built into the very fabric of their cultures. This, however, is not a situation where one can readily conclude it is about "Japanese companies," because the third company with headquarters on the island of Honshu, Nissan, came in dead last. This is the "How did that happen?" portion. The Nissan score of 203 puts it 125 points behind Toyota. There hasn't been a number that low since the then-Chrysler Corp. scored 187 in 2010, when the company was clawing its way out of the recession. Clearly, the suppliers don't feel particularly engaged by the buyers at Nissan. Henke explains that whether a company does well or not on the WRI is rather simple. All people do things based on what they're measured on. "If you're measured on taking 10% out of your annual buy, you immediately know how to do it. But if you're also measured on improving relations, suddenly there is a new dynamic as to what you can do to achieve both.
