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.

Next Toyota Prius coming in 60-mpg 'Eco Grade' version?

There's some mystery surrounding the fuel economy level of the next-generation Toyota Prius. The closest we've had to an official number is 55 miles per gallon, which was hinted at by Toyota Motor Corporation's managing officer, Satoshi Ogiso, last year. That number wasn't an official target, but the company even provided a graphic (above) showing how each next generation Prius beat the previous one by four or five mpg. Since the current, third-gen model gets 50, well, we have been left to guess that 55 is the next logical target. But, according to a new report in Automotive News, the new, fourth-generation Prius that's due next year will come in two versions, with one having a bigger ego – sorry, eco – than the other. AN says that the model will arrive with a standard nickel-metal hydride battery pack in a version that gets "about 55 mpg" and then a new "eco grade" version with a li-ion battery that "will be rated at more than 60 mpg." AN says this information came from company executives who were speaking at an August meeting with Toyota dealers. Our sources within Toyota say that they haven't heard anything about two high-efficiency models, so we'll take this with the requisite grain of salt. The current version of the Prius Plug-In Hybrid does use lithium-ion batteries, but this is the non-plug model the dealers are talking about. We think. The dual-battery strategy is certainly a rumor we've heard before. We had thought that the li-ion pack would be for an extended EV range (the current Prius has a barely noticeable EV-only range), but such a pack would be lighter and could boost efficiency, too. In other words, we look forward to hearing more during the upcoming auto show season.

Camry, Avalon Hybrids involved in stop-sale of 50,000 Toyota vehicles

A number of popular Toyota vehicles can currently not be sold thanks to something called a "stop-sale" order. The reason is that the seat heater on these vehicles - which include the 2013 and 2014 Camry, Camry Hybrid, Avalon, Avalon Hybrid, Sienna, Corolla, Tacoma and Tundra models - "does not meet a provision of US Federal Motor Vehicle Safety Standards (FMVSS) requiring materials to retard flame at a specified rate." In other words, the seat heater could burn too fast. There have been no reports of fires or injuries due to the issue. Toyota told AutoblogGreen that around 50,000 vehicles are affected. No Scion or Lexus vehicles have the problem. The exact fix has not been identified, but Toyota said it is preparing a modification for all vehicles still on dealer lots, but there has not yet been an official recall. Instead, Toyota filed a "Non-Compliance Information Report" with the National Highway Traffic Safety Administration (NHTSA) today. You can read Toyota's official statement below. Toyota and NHTSA are also looking at around 30,000 2007-2008 model year Camry Hybrids for brake issues. Seat Heater Non-Compliance Issue Creates Temporary Stop Sale On Certain Toyota Models January 30, 2014 Toyota has informed the National Highway Traffic Safety Administration (NHTSA) that it has initiated a stop sale of certain Avalon, Avalon Hybrid, Camry, Camry Hybrid, Corolla, Sienna, Tacoma and Tundra vehicles equipped with seat heaters in order to address a non-compliance issue. In involved vehicles, the seat heater, which is a small portion of the soft materials of the seat assembly, does not meet a provision of U.S. Federal Motor Vehicle Safety Standards (FMVSS) requiring materials to retard flame at a specified rate. Toyota is preparing a modification for this condition, which will be implemented on all covered vehicles in dealer inventory. There have been no reports globally of any related incidents in the field with units in operation. Per NHTSA regulations, Toyota will file a Non-Compliance Information Report today.
