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 FT-86 Open Concept leaves us feeling flushed

When last we checked in on our topless would-be hero, the Toyota FT-86 convertible had been reportedly placed on "indefinite hold." That was back in early October, not long after Toyota had trotted out the rear-wheel-drive canvasback to Scion dealers as a possible future product carrot if they decided not to turn in their franchises. And yet, we're here at the Tokyo Motor Show, where Toyota has taken the time to at least repaint the FT-86 Open Concept in "Flash Red," if not build a whole other car (the original Geneva showcar was white). It's enough to make our heads spin like a teenager on the verge of a breakup. Will they? Won't they?
At this point, we still don't know any more than you do - the last word we heard out of Toyota was not encouraging, although the story was that the program could still be fast-tracked if management had a change of heart. As the car has never been seen before in Japan, perhaps Toyota is merely extending its domestic audience a courtesy view before it lines this showcar in mothballs, or maybe they're still trying to make a decision on its fate and gauging public reaction on the homefront.
Interestingly, in a new story published today, Automotive News quotes Subaru brand boss Yasuyuki Yoshinaga downplaying the likelihood of a production model, saying flatly "We make the car, so if we don't make it, it can't happen." The executive went on to note, "Our engineering department told me that losing the entire roof requires a complete redesign of the structure. It would need a big change." Given that such a car would probably trade in rather small volumes, that sounds like a significant hurtle.

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.
