Toyota recalling 1.9M Prius models globally for software update

Toyota has announced a set of voluntary recalls covering 960,000 Prius, RAV4, Tacoma and Lexus RX350 models in the United States to address two separate issues. Worldwide, Toyota will have to recall a total of 1.9 million Prius cars.
The Prius recall affects about 700,000 2010-2014 models in the US, due to a fault in the motor/generator control ECU and hybrid control ECU software. It says that the current software could result in high temperatures on certain transistors and possibly damage them. When it fails, the error forces the car into failsafe mode. Toyota says that in rare circumstances, it could even shut the hybrid system down while the car is being driven.
Toyota spokeswoman Shino Yamada told Automotive News that the software update should take about 40 minutes, and dealers would start to be notified about affected vehicles today. She also told them that the first reported glitch occurred in May 2011 in the US when the system overheated and the car entered failsafe mode. The affected cars were built between March 2009 and Feb. 5, 2014, according to Automotive News. Toyota says that it has received no reports of accidents or injuries caused by either fault.

Toyota reaffirms commitment to body-on-frame SUVs

Toyota sold 121,055 Highlander CUVs in 2012, according to Automotive News. By comparison, it sold 78,457 examples of four different body-on-frame, truck-based SUVs (4Runner, FJ Cruiser, Sequoia and Land Cruiser). One could argue then, that the traditional SUVs aren't pulling their weight from a sales perspective. Yet that isn't stopping Toyota from reaffirming its commitment to a segment that has seen its former champions - Ford, General Motors and Chrysler - abandon it with alarming speed. Ford and GM still offer body-on frame utilities, but only in the very largest offerings, catering to seven or even eight passengers. Everything outside of the Expedition or Tahoe rides now on a unibody.
Toyota's decision to stick with the technology is good news if you're in the market for smaller SUVs that are still capable of heading well off the beaten path. Outside of the Jeep Wrangler, Grand Cherokee (a unibody) and perhaps Nissan Xterra, there's not much in terms of capable SUVs between $20,000 and $50,000. As the Toyota brand's US head, Bill Fay, says, "Clearly, the trend has shifted, but there is still an owner base that is interested in these vehicles."
We don't doubt Fay on that, but it may also be somewhat telling that Toyota's SUV lineup is aging, and we haven't seen or heard much about replacement models in the pipeline. Admittedly, the 4Runner (pictured) has been facelifted for 2014, but it's mostly cosmetic in nature. Despite Toyota's posturing, we still expect its body-on-frame lineup to thin in the coming years as sales dwindle and escalating fuel-economy standards make business cases even tougher. Here's hoping that Toyota manages to keep at least one rough-and-tumble SUV in its lineup in the coming years.

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.
