Toyota adds 1.6m cars to Takata inflator recall list

As part of the Takata airbag inflator recall expansion announced by NHTSA earlier this month, Toyota has listed an additional 1.6 million cars that will need to have inflators or airbag assemblies replaced. This brings the total of recalled Toyota, Scion, and Lexus vehicles to 4.73 million. Other automakers will announce their expanded recall lists this week as well. This round of recalls affects some but not all vehicles with the following model names and years: 2009–2011 Toyota Corolla and Matrix 2006–2011 Toyota Yaris 2010–2011 Toyota 4Runner 2011 Toyota Sienna 2008–2011 Scion xB 2007–2011 Lexus ES 2010–2011 Lexus GX 2006–2011 Lexus IS To see if your specific vehicle falls under recall, write down your VIN and go to toyota.com/recall; you can also check any recalls, Takata or otherwise, at safercar.gov/vin. Toyota will inform owners of affected vehicles by mail. Depending on the model, either the inflator or the entire airbag assembly will have to be replaced. Due to the number of vehicles that have already been recalled, it may take some time for the necessary parts to be available. A total of 11 deaths have been attributed to the faulty Takata inflators, and federal investigators now know why the parts are prone to failure. The state of Hawaii was the first to sue the auto supplier, with more states expected to follow. The 17 other automakers are required to announce their additions resulting from the May 4 expansion this week, so expect more of the 35 to 40 million vehicles to be listed soon.

Question of the Day: Ever consider driving a minivan?

Since I'm supposed to know something about cars, it happens all the time: friends and relatives ask me advice about what kind of vehicle they should get. Very often, the only type of vehicle that can check every item on their wish list (e.g., hauls lots of people and stuff, gets good fuel economy, has great crash-test ratings, can take four Great Danes camping, and so on) is a modern minivan... and, of course, nobody wants to hear this. I'm not a minivan person, they will wail, and so they end up with a cramped, fuel-swilling SUV or a not-so-space-efficient minivan-in-disguise CUV. So, is it worth becoming one of those minivan people in order to get the incredible usefulness of these masterpieces of vehicle engineering, or do you hold your head high and drive something that doesn't quite meet your needs?

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.
