Toyota recalls 4,000 Tacoma pickups over valve springs

When you build as many cars and trucks as Toyota does, you're bound to run into the occasional recall. In the past month alone, the Japanese auto giant has recalled over 800,000 Camry, Avalon and Venza models over problems with the air-conditioning units, and 10,000 more before that over windshield wiper issues. Now Toyota has issued another recall notice, but this time for far fewer vehicles.
The recall revolves around the engine valve springs in the 2013 and 2014 Tacoma, specifically those fitted with the standard 2.7-liter four-cylinder engine and not the optional 4.0-liter V6. The issue is that the valve springs are prone to cracking and breaking over time, and results from improper maintenance of the manufacturing equipment used by one of the two suppliers that outfit Toyota with the components in question.
All told, some 4,000 vehicles will be subject to the voluntary recall, the owners of which will receive notice by mail. If you think that could be you and want to get a jump on the problem, you can read the announcement below and call Toyota yourself.

Toyota settles first wrongful death suit related to unintended acceleration

Toyota's sales seem to have rebounded from the unintended acceleration issues from 2009 and 2010, but the automaker is far from done dealing with this situation. Following a settlement worth up to $1.4 billion for economic loss to affected vehicle owners, Toyota has settled rather than going to trial in a wrongful death lawsuit stemming from an accident in Utah in 2010 that left two passengers dead. This isn't the first case in which Toyota has settled, but it was the first among a consolidated group of cases being held in Santa Ana, CA.
According to The Detroit News, this case was scheduled to take place next month, and it was for a November 2010 incident in which Paul Van Alfen and Charlene James Lloyd were killed in a Camry when, based on findings by the Utah Highway Patrol, the accelerator got stuck causing the car to speed out of control and hit a wall; the terms of the settlement were not announced.
The article says that while Toyota will settle on some cases, it doesn't plan on settling on all of them as it still wants to be able to "defend [its] product at trial." This will probably be the case in suits claiming that software for the drive-by-wire accelerator was the cause of an accident in a Toyota or Lexus vehicle. The question of whether or not the electronic accelerator played any role in this problem has been a hot-button topic since the beginning. Toyota has issued recalls in the past to attempt to prevent unintended acceleration caused by trapped floor mats and faulty accelerator pedals, but it also says driver error was to blame in some instances.

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.
