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.

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.

2014 Toyota Aygo marks the spot [w/video]

Following the leaked pictures we showed you yesterday, we have the full battery of images and info of the all-new Toyota Aygo, in addition to our gallery of live photos from the floor of the Geneva Motor Show.
Like its cousins from Peugeot and Citroën, the Aygo foregoes a diesel engine in favor of a highly efficient gas powerplant. The 1.0-liter naturally aspirated 4-cylinder turns out 68 horsepower and 70 pound-feet of torque. When it hits the market, it'll be with either a five-speed manual transmission or a five-speed, X-Shift automated manual. The former will help the Aygo return 57.3 miles per gallon and hit 62 miles per hour in 14.2 seconds. Opting for the X-Shift variant will net drivers 56 mpg, with 62 arriving in a leisurely 15.5 seconds.
We'll admit, aside from the fuel efficiency, there's nothing terribly great about those numbers. Still, with its compact dimensions - it's only 136 inches long - and a curb weight of no more than 2,000 pounds, it should prove tossable in the bends.
