10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.

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 urges owners of old Corolla, Matrix and RAV4 models to park them until airbags are replaced

DETROIT — Toyota and General Motors are telling the owners of about 61,000 older Corolla, RAV4, Matrix/ Pontiac Vibe models to stop driving them because their Takata airbag inflators are at risk of exploding and hurling shrapnel. The urgent warning Monday covers: Certain Corolla compact cars and Matrix hatchbacks from the 2003 and 2004 model years. RAV4 small SUVs from 2004 and 2005. Also covered are about 11,000 Pontiac Vibes from 2003 and 2004, which are essentially the same as the Matrix and were made at the same California factory. Most of the vehicles are in the U.S. “If the airbag deploys, a part inside is more likely to explode and shoot sharp metal fragments, which could cause serious injury or death to the driver or passengers,” Toyota said in a statement. Owners can go to nhtsa.gov/recalls and enter their 17-digit vehicle identification number to see if their cars are affected. If you're not the original owner of the vehicle, the manufacturer's recall letter might not reach you, so be sure to do the VIN check. The recalled RAV4s have Takata driver's airbags while the Corolla and Matrix models have them on the passenger side. The Corolla and Matrix also are under a separate recall because their airbags can be deployed without a crash, the company said. Both companies said owners should contact a local dealer instead of driving the cars in for repairs. Dealers will provide options such as mobile repair, towing the car to a dealer, or vehicle pickup and delivery. Takata used volatile ammonium nitrate to create a small explosion to inflate airbags in a crash. But the chemical propellant can deteriorate over time when exposed to high temperatures and humidity. It can explode with too much force, blowing apart a metal canister and spewing shrapnel. At least 26 people have been killed in the U.S. by Takata inflators since May 2009, and at least 30 have died worldwide including people in Malaysia and Australia. In addition, about 400 people have been injured. The exploding airbags sent Takata of Japan into bankruptcy. The potential for a dangerous malfunction led to the largest series of auto recalls in U.S. history. About 100 million inflators were recalled worldwide. Recalls Pontiac Toyota Takata airbag recall
