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.

Scion pondering move upmarket?

Scion is simultaneously celebrating its ten-year anniversary with the 10 Series models and trying to figure out what to do with itself over the next ten years. Once a go-to consideration for young, first-time buyers who wanted something cool and different, in 2013 it has a model everyone is still talking about in the FR-S, a model few are still talking about in the iQ, and three models in between in the tC, xB and xD that make everyone wonder, "What happened?"
Automotive News spoke to Toyota's North American CEO, Jim Lentz - he was the VP in charge of Scion when it launched - about the options, and Lentz said one of them could be a move upmarket to challenge the established luxury brands that are moving downmarket. "There's going to be a big need in the $25,000 range for a fun-to-drive, nice-looking, value-oriented product," he said, and the FR-S, which starts at $25,255, could provide the platform for Scion to climb up a notch or two in price and perception. An idea like this could conceivably work in tandem with a proposal to move entry-level Scion products over to the Toyota brand - but remember, this is all just ideas on a whiteboard at the moment.
As opposed to an "entry-luxury fighter," the brand could swing back to the other option that was considered when it was formed, directly challenging the Korean makes that have usurped its cachet with first-time buyers. Lentz said Scion could go either way, and the tone of the piece seems to indicate that the final direction is still a ways away from being resolved.

Honda, Nissan and Mazda recalling 3 million vehicles for airbag inflators

Three million more vehicles can be added to the worldwide tally to be repaired for the faulty airbag inflators supplied by Takata. Honda, Nissan, and Mazda have all issued recalls to replace the bad part, including about 1.2 million of them in North America. NHTSA has been investigating all three companies, plus Chrysler and Toyota, for potentially affected vehicles.
Honda is recalling roughly 1.02 million Civic, CR-V, Odyssey and Element models In North America, built between April 2000 and October 2002. Mazda needs to repair 14,794 units of the RX-8 and Mazda6, and Nissan has 228,000 vehicles in North America to be fixed.
Chrysler is also starting what it calls a "regional field action" to replace the inflators in the 2006 Dodge Charger, according to a company spokesperson. The company says that it has not yet found the problem in any of its vehicles, but it's being done "out of an abundance of caution." The final number of Chargers affected will be announced later this week.
