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 asking NHTSA for waiver on 206K vehicles

Toyota has filed a petition with the National Highway Traffic Safety Administration asking for a waiver to avoid recalling about 206,271 2012-2014 Camry, Avalon, Corolla, Sienna, Tundra and Tacoma vehicles, some of its most popular models. The affected vehicles contain seat heaters that might not meet government flammability standards. Toyota says in the waiver that "the chance of fire or flame induced by a malfunctioning seat heater is essentially zero," according to The Detroit News. The automaker notes the part makes up less than one percent of the seat's weight.
Initial reports of the problem arose in late January when Toyota issued a stop-sale order for 2013 and 2014 model year versions of those vehicles. The automaker says that there have no been reports of fires or injuries in the affected cars, and the problem was discovered during testing by the South Korean government, according to The Detroit News.
We've reached out to Toyota for comment on this development and are awaiting a reply. We'll update this post if and when we hear back.

Recharge Wrap-up: First EV to attempt Dakar Rally, Mazda makes bioplastic parts

Zap and Jonway Auto brought their Urbee EV and their new Falcon A-380 SUV to the Peru Motor Show in Lima. Jonway sells its SUV and minivan in Lima through Dai-Ichi Motors, which displayed the cars at the show. According to the companies, their cars "received tremendous interest from the public," including private citizens as well as groups who would use the EVs for security guard service or campus use.

The state boasts almost half of the country's electric vehicles, thanks largely to state and local EV incentives that go beyond the federal tax rebate. California also leads the way in legislation, and nine other states have adopted California's ZEV mandate. Washington, Maryland, Georgia and DC also have their own EV incentives, while some utility companies also offer benefits for EV owners in other states. Still, EV sales have only made up about 0.7 percent of new vehicle sales in 2014. Read more at the US Energy Information Administration website. Toyota will be using landfill gas to help power its Kentucky manufacturing facility. Beginning in 2015, Toyota's Georgetown assembly plant will use electricity converted from landfill-sourced methane gas from Waste Services of the Bluegrass. It will provide enough energy to produce 10,000 vehicles each year. Plus it diverts methane - a greenhouse gas - from entering the atmosphere and helps improve the local air quality.

The dyed plastic doesn't require painting, and it reduces petroleum consumption and carbon emissions in the manufacturing process. The bioplastic will be used for interior parts in the all-new MX-5 before being put into use on the exterior of future vehicles. Mazda will display prototype parts at the Eco-Products 2014 exhibit in Tokyo. Read more in the press release below. Acciona will enter the first-ever zero-emissions vehicle (pictured) to compete in the Dakar Rally. The vehicle uses an electric motor and lithium ion batteries, as well as solar panels to power telemetry and security systems. The Dakar Rally will take place from January 4 through 17 through Argentina, Chile and Bolivia. See Acciona's Dakar EV in the video and read more in the press release below.
