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 teases 2014 4Runner, will debut on April 27

The 2014 Toyota 4Runner appears to be getting a styling refresh that is as out of the ordinary for Toyota as the venue at which it will be debuting. Launching on April 27 at the 2013 Stagecoach Music Festival in Indio, CA, the 2014 4Runner looks to be getting more of an in-your-face design. Toyota says this marks the first time it has ever revealed a new product at a music festival.
While we only see two images of the updated 2014 4Runner, the new headlights break from the rectangular shape present on the current model for an edgy, scalloped shape. Below the headlights are vertical air inlets - looking quite similar to the 2014 Subaru Forester XT - but it isn't clear if all models will get these or just special trim levels. The other image Toyota released was of the smoked, LED taillight.
As the presenting sponsor of the music festival, Toyota will have legendary off-road driver Ivan "Ironman" Stewart at the show as well as an off-road driving course for people to drive the automaker's trucks and SUVs. Scroll down for a press release giving some additional information about both the 2014 4Runner and the Stagecoach Music Festival.

NHTSA urges owners of recalled Takata airbag vehicles to take immediate action

The National Highway Traffic Safety Administration and the Department of Transportation are taking the unusual step of issuing a followup press release urging owners of certain recalled vehicles "to act immediately" to fix their cars and trucks. The problem in question concerns the repair campaigns for rupturing Takata airbag inflators issued in June and covers a long list of models from Toyota, Lexus, Honda, Acura, Mazda, BMW, Nissan, Infiniti, Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac.
While NHSTA doesn't specifically say why the recall is vital in the new release, Toyota's own explanation in its newly announced renotification campaign earlier today sheds some new light on the topic. According to the Japanese automaker, in testing, Takata found a possible link between the rupturing airbag inflators and high humidity. NHTSA is advocating that all owners pursue repairs immediately if they haven't already done so already. This is especially crucial for those drivers especially in Florida, Puerto Rico, Guam, Saipan, American Samoa, Virgin Islands and Hawaii because of the humid conditions there.
We don't need to tell you how dangerous an inadvertent airbag deployment could be - even in a stationary vehicle - but adding to the Takata issue is fears that the deployment could lead to shrapnel being sprayed into the cabin.
